There is a complex web of regulations and policies that govern data privacy. The most frequently cited are the Health Insurance Portability and Accountability Act (HIPAA), and the Payment Card Industry Data Security Standard (PCI DSS). European data protection laws often go even further, prohibiting any personally identifiable information from moving outside EU or country borders. This puts some obvious limits on unrestrained use of the public cloud. Organizations are also concerned that law enforcement or government officials could potentially access data directly from their cloud service provider, bypassing the company completely.
For example, European data protection laws prohibit personal data that can be linked to a specific person from moving outside of European Union (EU) or even specific country borders. Such laws can prohibit organizations from storing or processing data in the cloud because infrastructure providers may store, process or back up data in multiple global locations. In the U.S., regulations such as the Health Insurance Portability and Accountability Act (HIPAA) require maintaining security and privacy around personal health information (PHI). The complexity of doing so may dissuade healthcare providers from using cost-effective public cloud-based solutions that could slow the rising cost of healthcare.
One way to get around the issues of data security, residency, and privacy is to obfuscate the data that goes into the cloud. Two common methods of obfuscation are encryption and tokenization. Using either of these approaches ensures that data remains undecipherable to prying eyes while the organization enjoys the benefits of cloud-based applications. Encryption uses algorithmic schemes to transform plain text information into a non-readable cipher text. A key (or algorithm) is required to decrypt the information and return it to its original plain text format. Tokenization is an increasingly popular approach for the protection of sensitive data. It involves the use of data substitution with a token (or alias) as a replacement for the real values. Unlike encryption, which uses a mathematical process to transform data, tokenization uses random characters to substitute for the actual data. There is no “key” that can decipher the token and turn it back into real data.
In the process of tokenization, the sensitive data is sent to a centralized and highly secure server called a “vault” where it is stored securely. At the same time, a random unique set of characters (the token) is generated and returned for use in place of the real data. The vault manager maintains a reference database that allows the token value to be exchanged for the real data when it is needed again. Meanwhile the token value, which has no meaning whatsoever to prying eyes, can be used in various cloud-based applications as a reliable substitute for the real data.
Merchants often use tokenized data as a substitute for sensitive credit card information after a sale has concluded. This allows a merchant to perform sales analytics on customers' transactions without putting the real card data at risk. What's more, PCI prohibits the use of live card data for anything other than the payment transaction. By tokenizing post-transaction data, merchants can reduce their PCI burden because no sensitive data exists in their backend systems.
The same methods can be applied for other types of sensitive data, including patient records, customer account records, human resources information and so on. Tokenizing the real data takes it out of harm's way and addresses the requirements for security, residency, and privacy. Tokenized data can be stored and used anywhere—even in the cloud—because it cannot be turned back into the real data if lost or stolen.

An application refers to a software program, which on execution performs specific desired tasks. In general, several applications are executed in a run-time environment containing one or more operating systems (“OSs”), virtual machines (e.g., supporting Java™ programming language), device drivers, etc. Developers often use Application Development Frameworks (“ADFs”) (which are by themselves applications) for implementing/developing desired applications. An ADF provides a set of pre-defined code/data modules that can be directly/indirectly used in the development of an application. An ADF may also provide tools such as an integrated development environment (“IDE”), code generators, debuggers, etc. In general, an ADF simplifies application development by providing re-usable components which can be used by application developers to define user interfaces (“UIs”) and application logic by, for example, selecting components to perform desired tasks and defining the appearance, behavior, and interactions of the selected components. Some ADFs, such as “Oracle ADF” from Oracle Corp., are based on a model-view-controller (“MVC”) design pattern that promotes loose coupling and easier application development and maintenance.

Callable interfaces associated with MCS 122 may receive requests for services according to a communication protocol. Device application developers can connect to MCS 122 for their custom applications. In some embodiments, a callable interface associated with MCS 122 may be configured by the same person that develops an app, such that the person can implement a custom application to communicate with MCS 122.
Callable interfaces associated with MCS 122 may further enable enterprise computer systems 126 to communicate with MCS 122 according to a standardized protocol or format. Similar to application developers, those who manage enterprise computer systems can implement code (e.g., an agent system) that is configured to communicate with MCS 122 via one or more callable interfaces. Callable interfaces associated with MCS 122 may be implemented based on a type of a computing device, a type of enterprise computer systems, an app, an agent system, a service, a protocol, or other criterion. In some embodiments, callable interfaces associated with MCS 122 may support requests for services including authentication, compression, encryption, pagination with cursors, client-based throttling, non-repudiation, logging, and metrics collection. In some embodiments, callable interfaces associated with MCS 122 may be implemented for custom business-related services, such as authentication, policy enforcement, caching of responses, throttling of calls to MCS 122, translation between asynchronous and synchronous patterns, logging of calls to underlying services, or combinations thereof. In some embodiments, callable interfaces associated with MCS 122 may enable users to load custom code for implementation by cloud infrastructure system 102. The custom code may implement one or more callable interfaces associated with MCS 122 for cloud infrastructure system 102, which can enable users to access custom services or other enterprise computer systems.
Protocol translators associated with MCS 122 may process a message to determine a communication protocol for a message and/or to convert a message to a communication protocol for a destination. Protocol translators associated with MCS 122 may convert a request received from client computing devices 104, 106, or 108. The request may be converted from a format of a communication protocol supported by client computing devices 104, 106, or 108 to a format of a communication protocol supported by a service provided by cloud infrastructure service 102 or enterprise computer systems 126. Protocol translators associated with MCS 122 may convert a response received from a service provided by cloud infrastructure service 102 or enterprise computer systems 126. A response may be converted from a format of a communication protocol supported by a service provided by cloud infrastructure service 102 or enterprise computer systems 126 to a format of a communication protocol supported by client computing devices 104, 106, or 108.
Security services associated with MCS 122 may manage security authentication for requests received from any of client computing devices 104, 106, or 108. Security services associated with MCS 122 may protect the integrity of customer processes and enterprise data. To prevent system or data from being compromised, security authentication may occur when a request is received from client computing devices 104, 106, or 108. Security authentication may be performed before a request is dispatched for processing by cloud infrastructure system 102. The security authentication determined for a user may enable a user associated with a mobile computing device to have authorization to request services via MCS 122. The security authentication may reduce efforts for a user to authenticate for different requests and/or services requested via MCS 122. Security services associated with MCS 122 may be implemented as one or more functional blocks or modules configured to perform various operations authenticating security of a request.
Authentication services associated with MCS 122 may manage security authentication for requests received from client computing devices 104, 106, or 108. Authentication services associated with MCS 122 may determine security authentication for a user associated with a computing device that sends a request to MCS 122. Security authentication may be determined based on a time period, which may be tied to operation of an application (e.g., launching an application), a request, a computing device, an enterprise computer system, other criterion related to a request, or combinations thereof. Security authentication may be verified and granted for any one of the following, such as an individual request, one or more enterprise computer systems, a particular service, a type of service, a user, a computing device, other criterion for determining security authentication, or combinations thereof. In some embodiments, cloud infrastructure system 102 may store authentication information of users received from enterprise computer systems or authentication systems supporting enterprise computer systems. Cloud infrastructure system 102 may determine authentication by performing a lookup function to determine whether an identity of a user associated with a request has authority to make such a request. The stored authentication information may include information such as the type of requests, functions, enterprise computer systems, enterprise data, or the like that a user may be authorized to access. In some embodiments, infrastructure system 102 may initiate communication with a requesting computing device to determine authentication.
In some embodiments, security authentication may be determined based on a role associated with a user requesting a service. The role may be associated with a user requesting access to MCS 122. In some embodiments, a user may request services as a subscriber or tenant of MCS 122 who may be granted access to resources and/or services provided by MCS 122. Authentication may correspond to a user's subscription to MCS 122, such that a user may be authorized to request services via MCS 122 as a subscriber. In some embodiments, the subscription may be limited to a particular set of resources provided by MCS 122. Security authentication may be based on the resources and/or services accessible to the user of MCS 122. In some embodiments, a request may be provisioned a template during execution called a “runtime environment.” The runtime environment may be associated with resources that are allocated for a request, a user, or a device.
In some embodiments, authentication services associated with MCS 122 may request an identity management system to determine security authentication for the user. The identity management system may be implemented by cloud infrastructure system 102 (e.g., as identity management 114) or by another computer system that is external to cloud infrastructure system 102. Identity management 116 may determine security authentication of the user based on the user's role or subscription for accessing MCS 122. The role or subscription may be assigned privileges and/or entitlements with respect to an enterprise computer system, a service provided by an enterprise computer system, a function or feature of an enterprise computer system, other criterion for controlling access to an enterprise computer system, or combinations thereof.
Various different ADFs 124 may be provided in cloud infrastructure system 102. ADFs 124 provide the infrastructure code to implement agile SOA based applications. ADFs 124 further provide a visual and declarative approach to development through one or more development tools (e.g., “Oracle JDeveloper 11g” development tool). One or more frameworks provided by ADFs 124 may implement an MVC design pattern. Such frameworks offer an integrated solution that covers all the layers of the MVC architecture with solutions to such areas as Object/Relational mapping, data persistence, reusable controller layer, rich Web UI framework, data binding to UI, security and customization. Extending beyond the core Web based MVC approach, such frameworks also integrate with the Oracle SOA and WebCenter Portal frameworks simplifying the creation of complete composite applications.
In certain embodiments, ADFs 124 make it easy to develop agile applications that expose data as services by coupling a service interface to built-in business services provided by cloud infrastructure system 102. This separation of business service implementation details is performed in ADFs 124 via metadata. Use of this metadata-driven architecture enables application developers to focus on the business logic and user experience, rather than the details of how services are accessed. In certain embodiments, ADFs 124 store implementation details of services in metadata in a model layer. This enables developers to exchange services without modifying the UI, making the application extremely agile. Additionally, the developer creating the UI does not need to bother with business service access details. Instead, developers can focus on developing the application interface and interaction logic. Creating the user experience can be as simple as dragging-and-dropping the desired business services onto a visual page designer and indicating what type of component should represent that data.
In various embodiments, developers interact with ADFs 124 to create modules forming enterprise applications. The enterprise applications can be executed within the context of cloud infrastructure system 102. In various embodiments, developers interact with ADFs 124 to create modules forming mobile applications. The mobile applications can be executed within the context of cloud infrastructure system 102. Features of the present invention described below may be implemented using any desired combination of programming language and application development framework as will be apparent to one skilled in the relevant arts by reading the disclosure provided herein.
One or more frameworks provided by ADFs 124 may be embodied as Oracle ADF in one example. Accordingly, a framework in ADFs 124 can be based on an MVC design pattern. An MVC application is separated into: 1) a model layer that handles interaction with data-sources and runs the business logic, 2) a view layer that handles the application UI, and 3) a controller that manages the application flow and acts as the interface between the Model and the View layers. Separating applications into these three layers simplifies maintenance and reuse of components across applications. The independence of each layer from the others results in a loosely coupled, SOA.
In various embodiments, ADFs 124 provide tools and resources allowing developers to create an application in the form of multiple layers, each layer containing code modules/files implementing desired logic according to pre-defined specification. Thus, in one embodiment, ADFS 124 enables the application to be developed as four layers: a view layer containing code modules/files that provide the UI of the application, a controller layer containing code modules that control the flow of the application, a model layer containing data/code modules that provide an abstraction layer for the underlying data, and a business services layer containing code modules that provide access to data from various sources and handles business logic.
In certain embodiments, ADFs 124 let developers choose the technology they prefer to use when implementing each of the layers. Enterprise JavaBean (“EJB”), Web Services, JavaBeans, JPA/EclipseLink/TopLink objects, and many others can all be used as Business Services for ADFs 124. View layers can include Web based interfaces implemented with Java Server Faces (“JSF”), Desktop Swing applications and Microsoft Office front ends, as well as interfaces for mobile devices.
In one aspect, the view layer represents the UI of the application being developed. The view layer can include desktop, mobile, and browser-based views, each of which provides all or a portion of the UI and is accessible in a variety of manners corresponding to view type. For example, Web pages may be sent by the application in response to receiving client requests containing corresponding URLs. The Web pages may then be displayed by a browser on a display unit (not shown) associated with a requesting client system, thereby enabling users of the requesting client system to interact with the enterprise application. ADFs 124 support multi-channel access to business services allowing reuse of business services and access from a Web client, a client-server swing desktop-based application, Microsoft Excel spreadsheets, mobile devices such as a smart-phone, or the like.
The code files/modules forming the view layer (such as Web pages) may be implemented using one or more of hypertext markup language (“HTML”), Java server pages (“JSP”), and JSF. Alternatively, the UI may be implemented using Java components such as Swing, and/or XML. As further noted, the UI may leverage a user's experience and familiarity with desktop applications, such as Word and Excel by Microsoft.
As noted above, the relevant user-developed code/data modules are provided in each of the layers. However, each layer typically contains other pre-defined code/data modules provided by ADFs 124. Some of the pre-defined modules may be used during development, for example, as templates for developing the Web pages, for including desired functionality in the developed code etc. Other pre-defined modules (such as a URL rewriting module) may be deployed along with the developed application and may provide additional functionalities (mapping of requested URLs to internal names) to the user during execution of the enterprise application.
A controller layer contains code modules/files that control the flow of the application. Each controller object contains software instructions and/or data implemented according to a desired manner of presenting information in the view layer. The desired manner may include the specific Web pages to be displayed when links in another Web page are clicked/selected by the user, the page to be displayed when errors occur during execution, indicating the specific data to be stored/retrieved, etc.
In one aspect, the controller layer manages the applications flow and handles user input. For example, when a Search button is clicked on a page, the controller determines what action to perform (do a search) and where to navigate to (the results page). There are two controller options for Web-based applications in JDeveloper: the standard JSF controller or the ADF Controller that extends the JSF controller functionality. Whichever controller is used, application flow is typically designed by laying out pages and navigation rules on a diagram. An application's flow can be broken into smaller, reusable task flows; include non-visual components such as method calls and decision points in a flow; and create “page fragment” flows that run inside a region of a single containing page.
The code modules/files forming the controller layer are often implemented as Java servlets receiving the client requests and sending desired Web pages as corresponding responses. Controller objects may also be implemented, for example, as Apache Jakarta Struts controllers or according to the JSF standard.
A model layer contains data/code modules that connect various business services to the objects that use them in the other layers, such as to the controller objects discussed above or directly to desktop applications. Each abstract data object of the model layer provides a corresponding interface that can be used to access any type of business service executing in an underlying business service layer. The data objects may abstract the business service implementation details of a service from a client and/or expose data control methods/attributes to view components, thus providing a separation of the view and data layers.
In one aspect, the model layer consists of two components, data controls and data bindings, which utilize metadata files to define the interface. Data controls abstract the business service implementation details from clients. Data bindings expose data control methods and attributes to UI components, providing a clean separation of the view and model. Due to the metadata architecture of the model layer, developers get the same development experience when binding any type of Business Service layer implementation to the View and Controller layers.
In certain embodiments, ADFs 124 emphasize the use of the declarative programming paradigm throughout the development process to allow users to focus on the logic of application creation without having to get into implementation details. At a high level, the development process for a Fusion Web application usually involves creating an application workspace. Using a wizard, libraries and configuration needed for technologies selected by a developer are automatically added and an application is structured into projects with packages and directories.
By modeling database objects, an online database or offline replica of any database can be created, definitions edited, and schemas updated. Using a unified modeling language (“UML”) modeler, use cases can then be created for the application. Application control and navigation can also be designed. Diagrammers can be used to visually determine the flow of application control and navigation. Then, an underlying XML file describing the flow can be automatically created. A resource library can be used to allow a developer to view and use imported libraries by simply dragging and dropping them into the application. From database tables, entity objects can be created using wizards or dialogs. From those entity objects, view objects are created to be used by pages in the application. Validation rules and other types of business logic can be implemented.
In this example, a business services layer manages interaction with a data persistence layer. It provides such services as data persistence, object/relational mapping, transaction management, and business logic execution. The business services layer can be implemented in any of the following options: as simple Java classes, EJB, Web services, JPA objects, and Oracle ADF Business Components. In addition, data can be consumed directly from files (XML or CSV) as well as REST. Thus, each business service manages interaction with a corresponding data persistence layer, and also provides such services as object/relational mapping, transaction management, business logic execution, etc. The business services layer may be implemented using one or more of simple Java classes, Enterprise Java Beans, Web services, etc.
Business components represent a business service implemented using, for example, “Oracle ADF Business Components” from Oracle Corp., to provide interaction with databases, Web services, legacy systems, application servers, and the like. In one embodiment, business components of the business services layer contain a mixture of application modules, view/query objects, and entity objects, which cooperate to provide the business service implementation. An application module can be a transactional component/code module that UI clients communicate with for working with application/transaction data. The application module may provide an updatable data model and also procedures/functions (commonly referred to as service methods) related to user transactions.
An entity object may represent a corresponding row in a database table and simplifies the manipulation (update, deletion, etc.) of the data stored in the corresponding row. An entity object often encapsulates business logic for the corresponding row to ensure that the desired business rules are consistently enforced. An entity object may also be associated with other entity objects to reflect relationships existing between rows stored in the underlying database.
Privacy, Residency and Security (PRS) relates to addressing the issues of obfuscating data that goes into the cloud. Two common methods of obfuscation are encryption and tokenization. Using either of these approaches ensures that data remains undecipherable to prying eyes while the organization enjoys the benefits of cloud-based applications offered by cloud infrastructure system 102.
In this example, system 200 includes enterprise infrastructure system 225, PRS system 230, and cloud infrastructure system 220. Enterprise infrastructure system 225 can include one or more client devices, servers, networking devices, routers, proxies, gateways, and the like. As illustrated, enterprise infrastructure system 225 includes one or more client computing devices 205, 210, and 215 in communication with the PRS system 230 and the cloud infrastructure system 220. As illustrated, PRS system 230 includes a PRS server 235 and a private database 240, and the cloud infrastructure system 220 includes a cloud-based application 245 and a cloud database 250.
Client computing devices 205, 210, and 215 may be devices similar to those described above for 104, 106, and 108 shown in
Client computing devices 205, 210, and 215 may be portable handheld devices (e.g., an iPhone®, cellular telephone, an iPad®, computing tablet, a personal digital assistant (“PDA”)) or wearable devices (e.g., a Google Glass® head mounted display), running software such as Microsoft Windows Mobile®, and/or a variety of mobile OSs such as iOS, Windows Phone, Android, BlackBerry 10, Palm OS, and the like, and being Internet, e-mail, short message service (“SMS”), Blackberry®, or other communication protocol enabled. Client computing devices 205, 210, and 215 can be general-purpose personal computers including, by way of example, personal computers and/or laptop computers running various versions of Microsoft Windows®, Apple Macintosh®, and/or Linux OSs. Client computing devices 205, 210, 215 can be workstation computers running any of a variety of commercially available UNIX® or UNIX-like OSs, including without limitation the variety of GNU/Linux OSs, such as for example, Google Chrome OS. Alternatively, or in addition, client computing devices 205, 210, and 215 may be any other electronic device, such as a thin-client computer, an Internet-enabled gaming system (e.g., a Microsoft Xbox gaming console with or without a Kinect® gesture input device), and/or a personal messaging device, capable of communicating over one or more networks.
PRS server 235 may comprise one or more computers and/or servers. These computer systems or servers may be composed of one or more general purpose computers, specialized server computers (including, by way of example, personal computer (“PC”) servers, UNIX® servers, mid-range servers, mainframe computers, rack-mounted servers, etc.), server farms, server clusters, or any other appropriate arrangement and/or combination. One or more computer systems or servers associated with PRS server 235 may run an OS including any of those discussed above, as well as any commercially available server OS. One or more computer systems or servers associated with PRS server 235 may also run any of a variety of additional server applications and/or mid-tier applications, including hypertext transport protocol (“HTTP”) servers, file transfer protocol (“FTP”) servers, common gateway interface (“CGI”) servers, JAVA® servers, database servers, email servers, reverse proxies, and the like.
In certain embodiments, services provided by PRS server 235 may include a host of services, such as data privacy, residency, and security. PRS server 235 can be graphically installed and configured to support cloud application-specific requirements using application-specific adaptors. In some examples, PRS server 235 may provide data privacy by protecting data leaving enterprise infrastructure system 225, for example by using encryption or tokenization. PRS server 235 can seamlessly intercept data transmissions between client computing devices 205, 210, and 215 and cloud-based application 245, replacing sensitive data with replacement data, e.g., a token or encrypted data. As defined by the organization, sensitive data that cannot, or should not, leave enterprise infrastructure system 225 remains in private database 240, e.g., behind the firewall of PRS system 230, while users of the client computing devices 205, 210, and 215 experience virtually all of the functionality of the cloud-based application 245, regardless of where the sensitive data resides. PRS server 235 can perform “encryption on the fly” where instead of storing and managing, the sensitive data locally, the sensitive data is encrypted or tokenized before it is sent to cloud-based application 245, and decrypted or substitute with the sensitive data on the return. The sensitive data received by the cloud-based application 245 and optionally stored in cloud database 250 itself, if accessed directly without PRS system 230, would appear only as an encrypted list of values or tokens.
PRS server 235 may provide data residency by preventing data that meets certain conditions, e.g., sensitive data, from leaving enterprise infrastructure system 225. PRS server 235 can identify specific pieces of data from the data transmission that meet the conditions, save the specific pieces of data to the private database 240, generate replacement values (e.g., encryption values or tokens) for the real values of the identified specific pieces of data, and send the generated replacement values to the cloud-based application 245. The real values for the identified specific pieces of data remain resident locally in the private database 240, which may be governed by local statutes and operate under corporate policy. Thus, cloud-based application 245 operates with the replacement data, which can be stored in cloud database 250. PRS server 235 can categorize cloud application data, such as using categories as tokens, sortable tokens, encrypted values, and clear text. In some embodiments, the data can be protected on a field-by-field basis using an obfuscation strategy as discussed in detail herein.
PRS server 235 may provide data privacy, residency, and security by managing access to data stored in private database 240. PRS server 235 can ensure that only authorized access to cloud-based application 245 occurs from the organization. PRS server 235 can create a secure authentication link between enterprise infrastructure system 225 and cloud infrastructure system 220. In one embodiment, PRS server 235 is configured to utilize algorithmic schemes of encryption to transform plain text information detected in a network transmission into a non-readable cipher text. PRS server 235 may provide key management allowing PRS server 235 to encrypt and decrypt data within network transmissions. The key management may include the ability to generate, distribute, store, rotate, and revoke/destroy cryptographic keys as needed to protect the sensitive data with which they are associated. In other embodiments, PRS server 235 is configured to utilize tokenization for the protection of the sensitive data. PRS server 235 can use data substitution with a token (or alias) as a replacement for the real values. In the process of tokenization, PRS server 235 intercepts sensitive data and sends the data to private database 235 where it is stored securely. At the same time, PRS server 235 can generate a random unique set of characters (the token) and return the token for use in place of the real data. PRS server 235 (or private database 240) can maintain a reference database that allows the token value to be exchanged for the real data when it is needed again.
Accordingly, PRS server 235 can allow the encrypted value or the token value, which has no meaning whatsoever to prying eyes, to be used in various cloud-based applications as a reliable substitute for the real data, such as with cloud-based application 245. Cloud-based application 245 can be representative of one or more enterprise applications developed using ADFs 124 as discussed with respect to
In one aspect, the view layer represents the UI of the application being developed. The view layer can include desktop, mobile, and browser-based views, each of which provides all or a portion of the UI and is accessible in a variety of manners corresponding to view type. For example, Web pages may be sent by cloud-based application 245 in response to receiving client requests containing corresponding URLs from one or more of the client devices 205, 210, and 215. The Web pages may then be displayed by a browser on a display unit (not shown) associated with one or more of the client devices 205, 210, and 215, thereby enabling users of the one or more client devices 205, 210, and 215 to interact with cloud-based application 245. The code files/modules forming the view layer (such as Web pages) may be implemented using one or more of hypertext markup language (“HTML”), Java server pages (“JSP”), and JSF. Alternatively, the UI may be implemented using Java components such as Swing, and/or XML. As further noted, the UI may leverage a user's experience and familiarity with desktop applications, such as Word and Excel by Microsoft.
As noted above, the PRS server 235 may monitor (e.g., intercept) network traffic and enforce privacy, residency, and security policies. With regard to communications between the one or more client devices 205, 210, and 215 and cloud-based application 245, the PRS server 235 can intercept transmissions originating from the one or more client devices 205, 210, and 215 to enforce the privacy, residency, and security policies. In the illustrated example, the one or more client devices 205, 210, and 215 can send a network transmission that includes the following pieces of information: ADDRESS=“123 MAIN” and CONTACT=JOHN” to the cloud infrastructure system 220. The PRS server 235 can intercept the network transmission and inspect its contents to determine whether any of the pieces of information are subject to the privacy, residency, and security policies. For example, the PRS server 235 can determine that the “CONTACT” piece of information is sensitive data subject to the privacy, residency, and security policies, and should not be transmitted to the cloud infrastructure system 220. The PRS server 235 can modify the network transmission to encrypt or tokenize the information as follows, with the “CONTACT” piece of information being designated as sensitive or private data: ADDRESS=“123 MAIN” [Public Data] and CONTACT=“JIDL45” [Private Data]. PRS server 235 can store the cryptographic key and/or the original data together with a token map in private database 240. PRS server 235 can then forward the modified network transmission with the replacement values (e.g., encryption values or tokens) to cloud-based application 245.
With regard to communications between the one or more client devices 205, 210, and 215 and cloud-based application 245, the PRS server 235 can intercept transmissions destined for the one or more client devices 205, 210, and 215 in a reverse the process to enforce the privacy, residency, and security policies. In the illustrated example, the PRS server 235 can determine that the “CONTACT” piece of information has been encrypted or tokenized, and the PRS server 220 can modify the network transmission to decrypt or detokenize the information using the cryptographic key and/or the original data together with a token map retrieved from private database 240. The PRS server 235 can then forward the modified network transmission to the one or more client devices 205, 210, and 215.
In some embodiments, a model layer associated with cloud-based application 245 contains data/code modules that connect various business services to the objects that use them in the other layers, such as to the controller objects discussed above or directly to desktop applications. Each abstract data object of the model layer provides a corresponding interface that can be used to access any type of business service executing in an underlying business service layer. The data objects may abstract the business service implementation details of a service from a client and/or expose data control methods/attributes to view components, thus providing a separation of the view and data layers.
In one aspect, the model layer consists of two components, data controls and data bindings, which utilize metadata files to define the UI. Data controls abstract the business service implementation details from clients. Data bindings expose data control methods and attributes to UI components, providing a clean separation of the view and model. By modeling database objects, cloud database 250 can be created for use with cloud-application 245. From database tables, entity objects can be created using wizards or dialogs. From those entity objects, view objects are created to be used by pages in the application. Validation rules and other types of business logic can be implemented.
An entity object may represent a corresponding row in a database table and simplifies the manipulation (update, deletion, etc.) of the data stored in the corresponding row. An entity object often encapsulates business logic for the corresponding row to ensure that the desired business rules are consistently enforced. An entity object may also be associated with other entity objects to reflect relationships existing between rows stored in the underlying database.
Thus, an entity object can be an ADF Business Component that represents a row in cloud database 250 and simplifies modifying its associated attributes. The entity object can be defined by specifying the database table in cloud database 250 whose rows it will represent. Associations can then be created to reflect relationships between entity objects. At runtime, entity rows are managed by a related entity definition object and each entity row is identified by a related row key. Entity rows are retrieved and modified in the context of an application module associated with cloud-based application 245 that provides the database transaction to cloud database 250.
As the general approach of a PRS server is to sniff or monitor wire traffic and perform data encryption or tokenization on protected fields, it can be difficult to integrate this functionality with cloud-based applications utilizing components that share various entity objects as illustrated in
To overcome these problems, in some embodiments, the cloud infrastructure system 220 can provide one or more services for self-describing the configuration of entity objects, UI pages, etc. of cloud-based application 245 with respect to the PRS server 235. Cloud infrastructure system 220 can provide an API that allows an administrator of PRS server 235 (e.g., at the request of the organization associated with enterprise infrastructure system 225) to identify sensitive data at the data or component level of cloud-based application 245. For example, the administrator can mark the social security number attribute 450 of entity objects at the data level such that any and all contact and employee objects 415, 420 that include the social security number attribute 450 have their data protected no matter where the sensitive data is used outside of the enterprise infrastructure system 225. In another example, the administrator can mark the name attribute 450 of only certain types of entity objects (e.g., the employee object 420) at the component level such that only those entity objects used by the given component that include the name attribute 450 are protect when used by the given component outside of the enterprise infrastructure system 225. Cloud infrastructure system 220 can then dynamically generate a map between UI elements recognized by PRS server 235 and the marked fields. This way, cloud infrastructure system 220 can have a shared component protected no matter where it is used and what value is associated with the identifier. This reduces the need to have multiple entries maintained by the PRS server 235.
Once sensitive data objects are identified using the PRS server 235, in one embodiment, the administrator can (1) add hints to the component's underlying data layer and (2) add a protectionKey attribute to the component. When cloud-based application 245 generates a UI page using a protected entity object, any data involving those protected components is sent in the payload of the network transmission together with a map between the identifier and the field recognizable by the PRS server 235 to perform necessary data encryption/tokenization. Thus, when configuring components, a new attribute named protectionKey can be added to the EditableValue component that controls whether the value of the component should be protected or not. The value of the attribute can be the name of the component that the PRS server 235 recognizes. Logic can be added at the data binding layer of cloud-based application 245 to extract protection hints that include the value recognized by the PRS server 235. If protectionKey is not present at the component level, cloud-based application 245 can retrieve the protectionKey attribute from the data-binding layer. For requests sent to the cloud-based application 245, if there is protected data involved, a build id to protectionKey map can be put in the payload of the network transmission. Thus, instead of directly mapping component client identifiers to object/fields recognizable by the PRS server 235, the map can be generated on the fly based on a static configuration.
In one embodiment, cloud infrastructure system 220 maintains a list of protectable attributes/components used by cloud-based application 245. The cloud infrastructure system 220 may additionally send hints with the list of protectable attributes/components such as type information for protected fields to the PRS server 220. The hints may provide information concerning parameters of the protectable data. Cloud infrastructure system 220 returns response 510 having the following format:
<objects>
<object name=“emp” type=“object”>
</object>
</objects>
In block 512, the PRS server 235 generates a user interface using the information on the protectable attributes/components received from cloud infrastructure system 220. The user interface allows for an administrator of the PRS server 235 to configure one or more protectable attributes/components of the entity modeled as a protected attribute/component. In block, 514, an administrator of the PRS server 235 (e.g., at the request of the organization associated with enterprise infrastructure system 225) configures one or more protectable attributes/components of the entity modeled, e.g. field “fname” in object “emp”, in the user interface to be marked as a protected attribute/component. In some embodiments, the marking of the attribute/component as protected may further include an indication on the type of protection to be applied to the attribute/component (e.g., tokenization or encryption). In block 516, the PRS server 235 informs cloud infrastructure system 220 of the protected attribute/component by sending the protected attribute/component information generated with the user interface to the cloud infrastructure system 220. In one embodiment, the PRS server 220 sends message 518 having the following format:
<objects>
<object name=“emp” type=“object”>
</object>
</objects>
In block 520, the cloud infrastructure system 220 marks designated components or entity object attributes as protected. In block 522, the cloud infrastructure system 220 may send confirmation information for protected fields to the PRS server 220. Cloud infrastructure system 210 may return response 524 having the following format:
<objects>
<object name=“emp” type=“object”>
</object>
</objects>
and the generated UI or client component may have the following format:
AdfPage.PAGE.addComponents(newAdfRichInputText(‘it3’, {‘columns’: 10,‘maximumLength’: 10,‘protectionKey’:‘EMP_OBJ/Ename_FLD’));
and a subsequent payload of the response 612 may contain map information having the following format:
oracle.adf.view.rich.TOKENIZED={‘it3’:{‘EMP_OBJ/Ename_FLD’}’}
In block 614, the PRS server 235 intercepts response 612 and populates the UI or client component with any protected data from private database 240 using the map included in the payload of the response 612. For example, the PRS sever 235 uses the map to replace random tokenized values used for <field name=“fname” protect=“protect” tokenize=“tokenize”/> with the sensitive data values stored in the private database 240 for the same protected field: <field name=“fname” protect=“protect” tokenize=“tokenize”/>. The PRS server 235 then forwards the modified response 616 to the one or more client devices 205, 210, and 215. In block 618, the one or more client devices 205, 210, and 215 display the generated UI or client component that includes any protected data from the private database 240 in the protected fields.
In block 620, the one or more client devices 20, 210, and 215 may post data to the cloud infrastructure system 220. The posted data can include changes or updates to sensitive data of the protected fields within the UI or client component. In one embodiment, a client runtime (e.g., ADF Faces client) uses the tokenization information of the UI or client component to spoon feed mappings to the PRS server 235 using a well-known field (e.g., ProtectionKey). For example, the PRS server 235 may use the well-known field to look up its configuration and find corresponding actions (e.g., encryption or tokenizing). In block 622, the one or more client devices 205, 210, and 215 insert the mappings into a request 624 (e.g., generate ID→protectionKey Map such as oracle.adf.view.rich.TOKENIZED={‘r1:0:foo:it1’:{‘object’:‘emp’, ‘field’:‘fname’}}). The one or more client devices 205, 210, and 215 may generate the request 624 as follows to include the mapping from block 622:
r1:0:foo:it1=SecretFirstName
r1:0:foo:it5=PublicLastName
r2:1:bar:it1=publicemail@oracle.com
javax.faces.ViewState=!-12t5t4tf7q
org.apache.myfaces.trinidad.faces.FORM=f1
Adf-Page-Id=0
event=b5
event.b5=<m xmlns=“http://oracle.com/richClient/comm”><k v=“type”><s>action</s></k></m>
oracle.adf.view.rich.PROCESS=f1,b5
oracle.adf.view.rich.TOKENIZED={‘r1:0:foo:it1’:{‘object’:‘emp’, ‘field’:‘fname’}}
In block 626, the PRS server 235 intercepts the request 624, and replaces any protected data with encrypted or tokenized values using the map (e.g., ID→protectionKey Map) and stores the protected data in private database 225. The PRS 235 then forwards the modified request 628 to the cloud infrastructure system 220.
Thus, the administrator of the PRS server 235 can identify sensitive data at the data model/component level and mark them in a self-describing way. Any generated UI elements associated with cloud-based application can be dynamically mapped to object/field tokens recognized by the PRS server 235. This way, a shared component will always be protected no matter where it is used and what id values it has. Moreover, there is no need to add multiple entries to the PRS server 235.
The cloud database 250 can contain encrypted or tokenized versions of sensitive data. As suggested above, entity objects can share the same structure as well as share the same database table. Some entity objects can be protected while other entity objects are not protected. Traditionally, different database tables are required to serve different protection configurations consequently duplicating database tables.
To overcome these problems, in some embodiments, when the administrator of the PRS server 235 configures a protection rule of a component or a data object at the data object layer, a discriminate flag can be defined to identify to which component or data object a particular row belongs. Therefore, all components or data objects sharing the same structure, while having different protection rules, can still share the same database table. This simplifies administration work of maintaining multiple similar database tables, but also allows reuse of common logic operating on the structurally similar components or data objects, without raising any security concerns.
Security configurations (i.e., protection rules of a component or a data object) can be placed at a layer above the database tables, e.g., data models layer 720. An attribute of each data model, e.g., TYPE, can be explicitly defined or implied. Because the discriminate flag is built into the data object only rows that belong to the data object should be picked up when the data object is used in the cloud-based application 245, e.g., such as being bound to various UI components. For example, in “Emp” object, “A” attribute is protected so it has two hints in data model layer: protectionState and protecionKey. These do not exist for “A” attribute in “Contact” object. Further, in “Contact” object, “B” attribute is protected so it has two hints in data model layer: protectionState and protecionKey. These do not exist for “B” attribute in “Emp” object. Data protection, therefore, is configured at the data object level so only the rows that belong to the data object will be subject to encryption/tokenization.
A data object can be bound to one or more UI components in UI layer 730. Typically, the data object is bound to a UI component for rendering one or more attributes of the data object. For example, a data object from data models layer 720 may be exposed to the UI layer 730 thru standard expression language such as <af:inputText id=“FIELD1” value=“# {EMPbinding.A.inputValue}”/>. In document object model layer 740, the rendered UI component can include identifiers indicating that certain document object models (DOM) elements are protected fields. As discussed above, the identifiers may include token identifiers generated by the PRS server 235.
In step 810, a database table definition supporting a plurality of data objects is received. The database table can be defined to support a plurality of data objects. For example, a person table can include columns corresponding to a superset of attributes shared among the plurality of data objects. In step 820, at least one column is designated as the discriminate flag for the data objects. In some embodiments, a predetermined column of the database table can be used or a new column can be created for the discriminate flag.
In step 830, at least attribute of a data object supported by the database tables is designated as a protected field. As discussed above with respect to providing a self-describing configuration, the administrator of the PRS server 235 can request a list of data objects used by the cloud-based application 245. The administrator can select which data objects (and/or their individual attributes) are subject to security policies and send that information to cloud-based application 245. Cloud based application 245 can then configure any database tables, data models, and components that are required to be protected.
In step 840, data is stored in the database table commingling protected and non-protected data. Thus, when the administrator of the PRS server 235 configures a protection rule of a component or a data object at the data object layer, a discriminate flag can be defined to identify to which component or data object a particular row belongs. Therefore, all components or data objects sharing the same structure, while having different protection rules, can still share the same database table. This simplifies administration work of maintaining multiple similar database tables, but also allows reuse of common logic operating on the structurally similar components or data objects, without raising any security concerns.
As different data objects can have different protected fields, certain operations performed by cloud-based application 245 can become invalid if the operation is performed against protected fields. In some embodiments, the cloud-based application 245 can automatically determine operations that might be unsupported to avoid user confusion. For example, the cloud-based application 245 can exam all possible operators on protected data and make intelligent decisions on enabling/disabling them. This can greatly reduce the amount of work required to avoid generating erroneous results on certain operations performed against protected data. Self-describing configurations come are useful this case because when changes are made to the protection state of a certain field, the cloud-based application 245 becomes aware of the change and any related operators can be automatically enabled/disabled. Some examples of operations that can be enabled/disabled include server side validation on protected data, auto-suggest behavior on protected data, allow exact match on searching against protected data, sorting against protected data, and the like.
In step 910, a data model layer configuration is generated in the data model layer and received at the PRS server 235. For example, the PRS server 235 can utilize an API of the cloud infrastructure system 220 to obtain data model attributes that are subject to security policies. The data model layer configuration may have the following format:
<EMP_OBJAttribute
Name=“Ename”
AttrName=“FName”>
<Properties>
</Properties>
</EMP_OBJAttribute>
In step 920, one or more protected fields are determined. As discussed above with respect to providing a self-describing configuration, the administrator of PRS server 235 can request a list of data objects used by cloud-based application 245. The administrator can select which data objects (and/or their individual attributes) are subject to security policies and send that information to cloud-based application 245. Cloud based application 245 can then determine which fields are protected.
In step 930, operations than can be performed using protected fields are determined. This may include determining whether a protected field is searchable, used in an autocomplete, or the like. In step 940, the cloud-based application 245 is configured based on the determined operations that can be performed on protected fields. In one embodiment, the cloud-based application 245 can be configured when processing validators on protected data to only process a required check and skip any other validators. Cloud-based application 245 can be configured to add logic to control auto-suggest behavior on protected data. Cloud-based application 245 can be configured when rendering a query page to only allow exact match search operators. Cloud-based application 245 can be configured when rendering a table to disable sorting on columns from protected data objects.
One operation that can be performed by cloud-based application 245 that may become invalid if it is operated against protected fields is search. When a certain field is protected, search becomes a challenge. Traditionally, either search functionality is compromised to only support exact match, or the PRS server 235 has to have a complete copy of every single searchable row with data replications setup between the cloud database 250 and private database 240. The PRS server 235 then needs to perform both searching on the sensitive data and rendering logic to render the final result.
In some embodiments, the one or more client devices 205, 210, and 215 can federate or centralize search results generated from searching the private database 240 and the cloud database 250. Rendering of a page associate with the cloud-based application 245 can be very complicated. For example, it can be a huge task for users to integrate the cloud-based application 245 with the PRS server 235 if the PRS server 235 has to render the cloud-based application 245. By using a client side federated search, the amount of integration work may be reduced, and the cloud-based application 245 can render the final result page completely so all pages will have the same look and feel, and be consistent. Thus, a federated search makes a search on protected and non-protected fields transparent to an end user. Additionally, there is no searchability compromise on the sensitive data.
In various embodiments, the one or more client devices 205, 210, and 215 split the original search into two searches. The one or more client devices 205, 210, and 215 split the original search based on a marked protected field map as in block 610 of
For example, “Emp” object “firstName” attribute may be protected with protectKey EMP_OBJ/Ename_FLD, when a user does search “FirstName startwith ‘B’”, the original search request contains all the necessary information. The PRS server 235 intercepts the request, searches FirstName in the private database 240, updates the payload of the request with the tokenized values of all matched FirstNames, and passes on the request to cloud-based application 245. The cloud-based application 245 will then search the cloud database 250 with the tokenized values from the PRS server 235 and generates the final result dataset, which is used in final page rendering. The rendered page will be sent back to the one or more client devices 205, 210, and 215. The PRS server 235 intercepts the response and converts the tokenized values to real text before sending to the one or more client devices 205, 210, and 215. The searched results of protected fields from the PRS server 235 and the non-protected fields search results directly done in the cloud-based application 245 are combined in a final dataset.
In various embodiments, when a user initiates a search, if any of the search criteria is on protected fields, the PRS server 235 can apply the search against the private database 240. The PRS server 235 can generate a result sets as a set of qualified rows identified by row keys. The set of row keys are then sent to a search request for the cloud-based application 245. When cloud-based application 245 handles the search request, the qualified set of row keys will be used to filter out the final search result. For example, the row keys are used to identify the tokenized or encrypted data that match the search criteria and the tokenized or encrypted data are added to the search result obtained from running the search criteria against the non-protected data in the cloud database 250 The final search result will be rendered and sent back to the one or more client devices 205, 210, and 215 to display as a response to the original search request.
In step 1010, a query is received. For example, the one or more client devices 205, 210, and 215 can construct a query from information provided by a user and the cloud-based application 245 can receive the query from the one or more client devices 205, 210, and 215. The query can include search criteria applicable to protected and non-protected fields, e.g., a search of a person's first and last name where the first name is non-protected data but the last name is protected data. In step 1020, search criteria related to protected fields is sent to a data security provider such as the PRS server 235. In one embodiment, the one or more client devices 205, 210, and 215 send the entire query to PRS server 220 for processing on protected fields. PRS server 235 can then send the search results together with the original query to cloud-based application 230. For example, in step 1030, search criteria related to public fields is sent to a cloud-based application together with result of protected fields search. In some embodiments, the search criteria for each private database 225 and cloud database 235 can be sent independently.
In step 1040, any final results of the search are rendered using protected fields results and cloud search results. In one embodiment, when a user initiates a search, if any of the search criteria is on protected fields, PRS server 220 can apply the search against private database 225. PRS server can generate a result sets as a set of qualified rows identified by the row keys. The set of row keys are then sent to a search request for cloud-based application 230. When cloud-based application 230 handles the request, the qualified set of row keys will be used to filter out the final search result. Only the final search result will be rendered and sent back to client device 215 to display.
The final search result includes a combination of cloud data and tokenized/encrypted data that satisfied the search criteria against private database 240. The tokenized/encrypted data can be replaced with data from private database 240 before being displayed by the one or more client devices 205, 210, and 215. Accordingly, search results from both the private database 240 and the cloud-database 250 can be federated to provide a more seamless search experience to the user.

Communications subsystem 1224 provides an interface to other computer systems and networks. Communications subsystem 1224 serves as an interface for receiving data from and transmitting data to other systems from computer system 1200. For example, communications subsystem 1224 may enable computer system 1200 to connect to one or more devices via the Internet. In some embodiments communications subsystem 1224 can include radio frequency (RF) transceiver components for accessing wireless voice and/or data networks (e.g., using cellular telephone technology, advanced data network technology, such as 3G, 4G or EDGE (enhanced data rates for global evolution), WiFi (IEEE 802.11 family standards, or other mobile communication technologies, or any combination thereof), global positioning system (GPS) receiver components, and/or other components. In some embodiments communications subsystem 1224 can provide wired network connectivity (e.g., Ethernet) in addition to or instead of a wireless interface.
In some embodiments, communications subsystem 1224 may also receive input communication in the form of structured and/or unstructured data feeds 1226, event streams 1228, event updates 1230, and the like on behalf of one or more users who may use computer system 1200.
By way of example, communications subsystem 1224 may be configured to receive data feeds 1226 in real-time from users of social networks and/or other communication services such as Twitter® feeds, Facebook® updates, web feeds such as Rich Site Summary (RSS) feeds, and/or real-time updates from one or more third party information sources.
Additionally, communications subsystem 1224 may also be configured to receive data in the form of continuous data streams, which may include event streams 1228 of real-time events and/or event updates 1230, that may be continuous or unbounded in nature with no explicit end. Examples of applications that generate continuous data may include, for example, sensor data applications, financial tickers, network performance measuring tools (e.g. network monitoring and traffic management applications), clickstream analysis tools, automobile traffic monitoring, and the like.
Communications subsystem 1224 may also be configured to output the structured and/or unstructured data feeds 1226, event streams 1228, event updates 1230, and the like to one or more databases that may be in communication with one or more streaming data source computers coupled to computer system 1200.
Computer system 1200 can be one of various types, including a handheld portable device (e.g., an iPhone® cellular phone, an iPad® computing tablet, a PDA), a wearable device (e.g., a Google Glass® head mounted display), a PC, a workstation, a mainframe, a kiosk, a server rack, or any other data processing system.
Due to the ever-changing nature of computers and networks, the description of computer system 1200 depicted in the figure is intended only as a specific example. Many other configurations having more or fewer components than the system depicted in the figure are possible. For example, customized hardware might also be used and/or particular elements might be implemented in hardware, firmware, software (including applets), or a combination. Further, connection to other computing devices, such as network input/output devices, may be employed. Based on the disclosure and teachings provided herein, a person of ordinary skill in the art will appreciate other ways and/or methods to implement the various embodiments.
In the foregoing specification, aspects of the invention are described with reference to specific embodiments thereof, but those skilled in the art will recognize that the invention is not limited thereto. Various features and aspects of the above-described invention may be used individually or jointly. Further, embodiments can be utilized in any number of environments and applications beyond those described herein without departing from the broader spirit and scope of the specification. The specification and drawings are, accordingly, to be regarded as illustrative rather than restrictive.
