Patent Application
20100218249
Computing devices are utilized by virtually everyone and in many different types of contexts (e.g., personal, social, professional, and so on). For example, it is common to see people communicating (e.g., telephone calls, text messages, emails, data transfer, and so forth) no matter where that person might be located (e.g., in a supermarket, in a library, taking public transportation, and so forth). As technology advances, so does the speed of communications and the demand for increased computing power. Further, data can be transferred across the country or across the globe in a matter of seconds. Based on the increased demands for computing capabilities, people are requiring more and more resources to be available for communicating electronically, whether the communication is with friends, family, coworkers, or others.
Computing technology has evolved such that touch screens and other devices (e.g., cameras) can track a user's gestural movements and make intelligent decisions regarding those movements. It has also become more commonplace for users to share a single computing environment and work together and/or separately within that computing environment. Since the demand for electronic computing devices is at an all time high, it is important to provide users with anytime, anywhere computing capabilities.
However, concerns can arise relative to security in a shared computing environment, especially when others within the computing environment can provide input possibly confused with another user. Such concerns can relate to protecting users from unauthorized inputs being received by the environment and any data security that can be associated.
The following presents a simplified summary of the innovation in order to provide a basic understanding of some aspects described herein. This summary is not an extensive overview of the claimed subject matter.

As utilized herein, terms “component,” “system,” “analyzer,” “authenticator,” “store,” “engine,” “modulator,” and the like are intended to refer to a computer-related entity, either hardware, software (e.g., in execution), and/or firmware. For example, a component can be a process running on a processor, an object, an executable, a program, a function, a library, a subroutine, and/or a computer or a combination of software and hardware. By way of illustration, both an application running on a server and the server can be a component. One or more components can reside within a process and a component can be localized on one computer and/or distributed between two or more computers.
Various aspects will be presented in terms of systems that may include a number of components, modules, and the like. It is to be understood and appreciated that the various systems may include additional components, modules, etc. and/or may not include all of the components, modules, etc. discussed in connection with the figures. A combination of these approaches may also be used. The various aspects disclosed herein can be performed on electrical devices including devices that utilize touch screen display technologies and/or mouse-and-keyboard type interfaces. Examples of such devices include computers (desktop and mobile), smart phones, personal digital assistants (PDAs), and other electronic devices both wired and wireless.
Furthermore, the claimed subject matter may be implemented as a method, apparatus, or article of manufacture using standard programming and/or engineering techniques to produce software, firmware, hardware, or any combination thereof to control a computer to implement the disclosed subject matter. The term “article of manufacture” as used herein is intended to encompass a computer program accessible from any computer-readable device, carrier, or media. For example, computer readable media can include but are not limited to magnetic storage devices (e.g., hard disk, floppy disk, magnetic strips . . . ), optical disks (e.g., compact disk (CD), digital versatile disk (DVD) . . . ), smart cards, and flash memory devices (e.g., card, stick, key drive . . . ). Additionally it should be appreciated that a carrier wave can be employed to carry computer-readable electronic data such as those used in transmitting and receiving electronic mail or in accessing a network such as the Internet or a local area network (LAN).

The surface computing equipment 104 can further allow interaction with and among a multitude of users. For example, the surface computing equipment 104 can be include in an environment 102 where a multitude of users interact, such as a meeting room, a coffee shop, and so forth. As the trend moves to using any surface (e.g., table, wall, and so forth) as a display, there can be multiple individuals interacting with the display at substantially the same time. Further, the surface computing environment 102 can allow users to share a single computing environment and work together and/or separately within that computing environment (e.g., classroom setting, business setting, conference, symposium, seminar, personal or family setting, and so forth). In addition, the surface computing environment 102 can be utilized to access and interact with user data. However, with multiple potential users interacting with the environment 102 simultaneously, users can be authenticated to allow interaction with user data. Further, user input can also be authenticated to prevent a user from accessing or interacting with data of other users.
System 100 includes an authentication object 106 that retains authentication information 108. The authentication object 106 can be a device such as an electronic device, a mobile device (e.g., cell phone, smart phone, PDA, etc.), a computing device and the like. In addition, the authentication object 106 can be a wearable object such as jewelry (e.g., ring, bracelet, etc.), a pendant, a key fob, a token or any other suitable object carried by a user and capable of retaining authentication information 108. According to an aspect, the authentication information 108 can be information that identifies a user 110. For example, the authentication can be a user ID for the surface computing equipment 104, a user ID associated with an online service (e.g., an online persona), a personal identification number, a password, a unique numeric identifier, a cryptographic key or the like.
The surface computing equipment 104 can obtain the authentication information 108 from the authentication object 106. For instance, the authentication object 106 can convey the information 108 to the equipment 104 via a variety of communication mediums as described infra. The surface computing environment 104 can analyze the authentication information 108 and identify user 110. Identification of user 110 can include associating the authentication information 108 with a particular user within the surface computing environment 102 and interacting with the surface computing environment 104. In addition, the authentication information 108 can be employed to obtain a user profile corresponding to user 110.
After identification of the user 110 via the authentication information 108, the surface computing equipment 104 can be employed to access and/or interact with data of user 110. For instance, the authentication information 108 can be employed to establish a secure communication channel between the authentication object 106 and the surface computing equipment 104. According to an aspect, user data can be obtained from the authentication object 106, another user object, a network (e.g., the cloud, a LAN, etc.) and so forth. Further, identification of the user 110 can be employed to associate user identify with touch input obtained by the surface computing equipment 104. For instance, certain user interactions with the surface computing equipment 104 can require validation of a user's identity such as, but not limited to, interactions to purchase products or services, to authorize future communications, or to provide personal data. The authentication object 106 and authentication information 108 can be employed by the surface computing equipment 104 to associate touch input with user 110 when required. Pursuant to an illustration, a location of the authentication object 106 relative to the surface computing equipment 104 and a location of the touch point on the surface computing equipment 104 can be evaluated to determine if an input is authenticated via the authentication object 106.
According to another aspect, the surface computing equipment 104 can provide visual feedback in the user interface to indicate that a particular touch input (e.g., a touch point) is authenticated. For example, the surface computing equipment 104 can utilize color visual feedback upon detecting a touch point. The color feedback can be colored light emitted at and around a location of a touch point. Visual feedback can be displayed in association with authenticated touch points. Moreover, each authenticated user can be assigned a particular color such that visual feedback of the particular color is displayed at touch points from an associated authenticated user. Upon verification of authentication information 108 from authentication object 106 of user 110, the surface computing equipment 104 can inform user 110 of an assigned color. Touch points originated from user 110 can be connected with visual feedback of the assigned color.
The surface computing equipment 104 and the authentication object 106 can employ a variety of mechanisms to exchange authentication information 108. For example, a radio frequency (RF) signal can be emitted through a user's body onto the surface computing equipment 104. The RF signal can include modulated authentication information 108. In such instance, the surface computing equipment 104 can include a capacitive array that detects the RF signal and employs filters to extract the authentication information 108. Whenever user 110 provides touch input to the surface computing equipment 104, the authentication information 108 is conveyed as well.
Pursuant to another illustration, the authentication information 108 can be conveyed via optical and/or physical mechanisms. For example, the authentication object 106 can include a display configured to transmit authentication information 108 by modulation of a backlight or through specific display patterns. In addition, the authentication object 106 can include a vibrator that can be configured to convey modulated authentication information 108 via a vibration pattern. Further, the authentication object 106 can be a mobile device or other electronic device capable of communication via short message service (SMS), near field communication (e.g., magnetic field induction), Bluetooth or other protocol that enables pairing, communication and data transfers.
The surface computing equipment 104 can associate authentication information 108 with touch input (e.g., associate input with user 110). The surface computing equipment 104 can be provided authentication information 108 simultaneously with touch input, for example, with modulated capacitance and/or near field communication. Pursuant to another example, the surface computing environment 104 can employ optical mechanisms. For instance, the authentication object 106 can be placed on a surface display. A halo or authenticated region can be established on the surface display around the object 106 such that any touch input obtained within the region is associated with user 110 and authenticated according to information 108 associated with user 110.
System 200 can be included in a surface computing environment 102 that can be located in a variety of places (e.g., store, office, coffee shop, library, and so forth). It should be understood that although only a single (piece of) surface computing equipment 104 is illustrated (for purposes of simplicity), surface computing equipment 104 can comprise a multitude of pieces or sets of equipment (e.g., dual monitors). Further, the equipment 104 can be of different types (e.g., a surface on a table and a surface on a wall).
System 200 can also include an authentication object 106 that retains authentication information 108 uniquely associated with a user 110. The authentication object 106 can be an electronic device such as a mobile device (e.g., cell phone, smart phone, etc.), a PDA, computer, laptop and the like. In addition, the authentication object 106 can be a wearable object such as a watch, ring, bracelet, pendant, necklace, earrings, and so forth. It is to be appreciated that the authentication object 106 can be any suitable object generally carried by user 110 and capable of retaining authentication information 108 and transmitting the information 108 to the surface computing equipment 104.
A user 110 can walk into a room (or other area) and begin interacting with the surface computing equipment 104. In accordance with some aspects, the authentication object 106 can be located in a user's pocket, purse, or worn on the user's person. The surface computing equipment 104 can obtain the authentication information 108 corresponding to user 110 from the authentication object 106 in user's 110 possession. The surface computing equipment 104 includes an authentication component 202 that analyzes the obtained authentication information 108. The authentication component 202 can determine an identity of the user 110. For instance, the identity can be a relative identity that distinguishes user 110 from other users interacting with the surface computing equipment 104. The identity can be a user ID for the surface computing equipment 104, a user ID for an online service and the like. In addition, the authentication component 202 can establish a secure communication channel between the authentication object 106 and the surface computing equipment 104. Pursuant to an illustration, the authentication component 202 and the authentication object 106 can utilize cryptographic keys to establish secure communications. It is to be appreciated that other security techniques can be employed such as, but not limited to, passwords, pass codes, PINs, keys, biometrics, visual verifications and so forth.
After establishment of a secure channel and/or identification of user 110, user data can be accessed via the surface computing equipment 104. For instance, user data can be verified and unlocked to the surface computing equipment 104 from the authentication object 106 over the established secure channel. In addition, identity of user 110 can be employed to retrieve, unlock and access user data retained by the surface computing equipment 104 or stored in a cloud (not shown).
People can interact with the surface computing equipment 104 in a “hands-on” manner and, at substantially the same time. System 200 enables multiple users to interact with the surface computing equipment 104 and with user data without interference from other, unauthenticated users. After authentication by the authentication component 202, touch input can be analyzed to determine if the input originates from an authenticated user. The surface computing equipment 104 includes a touch input component 204 that associates touch input with user 110 and enables the touch input to be processed accordingly.
According to an aspect, the authentication object 106 can convey authentication information 108 via a modulated capacitance transmitted through a user's body. When user 110 provides touch input to the surface computing environment 104, authentication information 108 is conveyed as well. The touch input component 204 can extract the authentication information 108 from the touch input to determine if the touch is authenticated. For instance, the touch input component 204 can employ a filter (e.g., low pass filter, high pass filter, etc.) to extract the authentication information 108. Accordingly, interactions related to data of user 110 or otherwise related to user 110 are not accepted by the surface computing equipment 104 unless the touch input component 204 extracts authentication information 108 associated with user 110. In another aspect, the authentication object can provide a modulate capacitance directly to the surface computing equipment 104. For instance, user 110 can utilize the authentication object 106 to provide touch input (e.g., tap the authentication object 106 on a surface).
Pursuant to another example, the touch input component 204 can determine authenticated input based on a location of touch input on a surface relative to a location of the authentication object 106. Location of touch input is determined via a capacitance array or other similar mechanism included in the surface computing equipment 104. Location of the authentication object 106 can be detected through optical (e.g., visual) or physical observation. For example, the authentication object 106 can be placed upon a surface of the surface computing equipment 104. A shadow or shape of the authentication object 106 can be detected and/or the authentication object 106 can vibrate to inform the surface computing equipment 104 of the object's location. In addition, near-field communications, Bluetooth or other wireless communication protocols can be employed to infer a location of the authentication object 106.
In accordance with an aspect, location of the authentication object 106, once determined, can be utilized to create an authenticated halo and/or region of the surface. For example, the authentication object 106 can be placed upon the surface and a region or area in the vicinity of the object 106 can be displayed. The touch input component 204 can associate touch input obtained within the region with the authentication information 108 and, correspondingly, the user 110.
It is to be appreciated that the system 200 can include any suitable and/or necessary interface component (not shown), which provides various adapters, connectors, channels, communication paths, etc. to integrate the authentication component 202 and touch input component 204 into virtually any application, operating and/or database system(s) and/or with one another. In addition, the interface component can provide various adapters, connectors, channels, communication paths, etc., that provide for interaction with and between the authentication component 202, the touch input component 204, and any other device and/or component associated with the system 200.
In accordance with some aspects, the authentication object 106 can employ a variety of mechanisms to transmit or convey authentication information to the surface computing equipment 104. For example, the authentication object 106 can modulate a display pattern (e.g., lighting), a vibration pattern, or a capacitance to convey authentication information. In addition, the authentication object 106 can employ near-field communication, Bluetooth, text messaging or other suitable wireless communication technology.
The authentication object 106 can include a display modulation component 302 that modulates a display to encode authentication information. For instance, the authentication object 106 can include a display (e.g., mobile device display with backlight) or other light emitting portion that can be configured to emit a pattern or light sequence that can encode authentication information. The surface computing equipment 104 can include cameras or light sensors (not shown) that obtain the modulated light sequence. The authentication component 202 can analyze the sequence and demodulate the information to facilitate authentication of the object 106 and corresponding user (not shown).
The authentication object 106 can include a vibration modulation component 304 that can control a vibrator (not shown) to transmit authentication information. The vibration modulation component 304 can convey authentication information through encoding the information with a rhythmic, character, numerical, binary or other encoding format. For example, the authentication object 106 can be placed in physical contact with the surface computing environment 104. The vibration modulation component 304 can activate a vibrator included in object 106 to provide authentication information to the authentication component 202 for verification.
In addition, the authentication object 106 includes a capacitance modulation component 306 that modulates information as a radio frequency signal that can be transmitted through a user's body. For example, the RF signal can alter a capacitance of user's touch on the surface computing equipment 104. The surface computing equipment 104 can receive capacitive input and process it accordingly to extract the RF signal encoded with authentication information. In accordance with another aspect, the authentication object 106 can transmit a capacitive signal generated by the capacitance modulation component 306 directly to the surface computing equipment 104. For instance, the authentication object 104 can be tapped on the surface to transmit the signal.
In accordance with another aspect, the authentication object 106 can transfer authentication information via a proximity communication protocol such as, but not limited to, Bluetooth, near field communications, or other similar protocol. The authentication object 106 includes a proximity communication component 308 that can establish a proximity communication channel with the surface computing equipment 104. Pursuant to an illustration, the authentication object 106 can pair with the surface computing equipment 104 upon moving into an appropriate range for communication. Upon successfully pairing, the authentication object 106 can transmit authentication information via the proximity communication channel for verification by the authentication component 202. In addition, the proximity communication channel can be employed to transfer other data beyond authentication information. For instance, user data retained by the authentication object 106 can be transmitted via the proximity communication channel after successful authentication.
According to another aspect, the authentication object 106 and surface computing equipment 104 can employ text messaging (e.g., SMS) to transfer authentication information. To facilitate such exchange, the authentication object 106 can include a messaging component 310. The authentication object 106 can utilize the messaging component 310 to send authentication information via a wireless communications network (e.g., cellular telephone network). For instance, a telephone number associated with the surface computing equipment 104 can be displayed within the surface computing environment 102. A user, employing the authentication object 106, can send a message to the displayed telephone number. The message can include authentication information analyzed and verified by the authentication component 202. According to one aspect, the message can include a request for a return message. The authentication object 106 can be placed on the surface computing equipment 104 such that a display or other feature that presents messages is visible to the surface computing equipment 104. The surface computing equipment 104 can employ sensors and/or cameras to observe a return message sent to the authentication device 106 and, accordingly, complete verification. In accordance with this example, a telephone number can represent a unique user identifier. In addition to verifying identity, visualizing the authentication object 106 can facilitate locating the object 106 to enable authentication of touch input as described above.
In accordance with an aspect, the authentication object 106 and the surface computing equipment 104 can communicate via a network 402. For example, the network 402 can be the Internet, a local area network, a wide area network, a wireless local area network, or other suitable network. Pursuant to an illustration, the authentication object 106 can be an Internet Protocol (IP) capable device such as, but not limited to a mobile device (e.g., cell phone, smart phone, etc.) or other electronic or computing device (e.g., PDA, laptop . . . ). The authentication object 106 can employ a network communication protocol such as TCP/IP to establish a communication channel with the surface computing equipment 104 over network 402. It is to be appreciated that other suitable communication and/or transport protocols can be employed for data exchange over network 402.
According to an example, the authentication object 106 and surface computing equipment 104 can establish a TCP/IP channel or other suitable network channel. The channel can be created when the authentication object 106 enters the surface computing environment. In addition, the channel can also be created by an explicit request of a user or by the surface computing equipment 104 when a user interacts therewith.
The authentication object 106 can utilize the channel to convey authentication information 108 to the surface computing equipment 104. The surface computing environment 104 can analyze the authentication information 108 to verify an identity of a user and/or the authentication object 106. In addition to identity verification, the authentication information 108 can be utilized to secure a communication channel. For instance, the authentication information 108 can include cryptographic keys that establish encryption of data between the authentication component 106, surface computing equipment 104 and/or any network entities included in network 402.
In accordance with another aspect, the secure channel can be employed for data transfers between the authentication object 106 and the surface computing environment 104. For instance, user data can be transferred therebetween. The user data can include photos, videos, music and/or any other use media, files or information. With verification of a user's identity via authentication information 108, the user data can be accessed, manipulated and interacted with on the surface computing equipment 104
Moreover, it is to be understood that the intelligence component 502 can provide for reasoning about or infer states of the system, environment, and/or user from a set of observations as captured via events and/or data. Inference can be employed to identify a specific context or action, or can generate a probability distribution over states, for example. The inference can be probabilistic—that is, the computation of a probability distribution over states of interest based on a consideration of data and events. Inference can also refer to techniques employed for composing higher-level events from a set of events and/or data. Such inference results in the construction of new events or actions from a set of observed events and/or stored event data, whether or not the events are correlated in close temporal proximity, and whether the events and data come from one or several event and data sources. Various classification (explicitly and/or implicitly trained) schemes and/or systems (e.g., support vector machines, neural networks, expert systems, Bayesian belief networks, fuzzy logic, data fusion engines . . . ) can be employed in connection with performing automatic and/or inferred action in connection with the claimed subject matter.
A classifier is a function that maps an input attribute vector, x=(x1, x2, . . . xn), to a confidence that the input belongs to a class, that is, f(x)=confidence(class). Such classification can employ a probabilistic and/or statistical-based analysis (e.g., factoring into the analysis utilities and costs) to prognose or infer an action that a user desires to be automatically performed. A support vector machine (SVM) is an example of a classifier that can be employed. The SVM operates by finding a hypersurface in the space of possible inputs, which hypersurface attempts to split the triggering criteria from the non-triggering events. Intuitively, this makes the classification correct for testing data that is near, but not identical to training data. Other directed and undirected model classification approaches include, e.g., naive Bayes, Bayesian networks, decision trees, neural networks, fuzzy logic models, and probabilistic classification models providing different patterns of independence can be employed. Classification as used herein also is inclusive of statistical regression that is utilized to develop models of priority.
The surface computing equipment 104 can further utilize a presentation component 504 that provides various types of user interfaces to facilitate interaction between a user and any component coupled to the surface computing equipment 104. As depicted, the presentation component 504 is a separate entity that can be utilized with the surface computing equipment 104. However, it is to be appreciated that the presentation component 504 and/or similar view components can be incorporated into the surface computing equipment 104 and/or a stand-alone unit. The presentation component 504 can provide one or more graphical user interfaces (GUIs), command line interfaces, and the like. For example, a GUI can be rendered that provides a user with a region or means to load, import, read, etc., data, and can include a region to present the results of such. These regions can comprise known text and/or graphic regions comprising dialogue boxes, static controls, drop-down-menus, list boxes, pop-up menus, as edit controls, combo boxes, radio buttons, check boxes, push buttons, and graphic boxes. In addition, utilities to facilitate the presentation such as vertical and/or horizontal scroll bars for navigation and toolbar buttons to determine whether a region will be viewable can be employed. For example, the user can interact with one or more of the components coupled and/or incorporated into surface computing equipment 104.
The user can also interact with the regions to select and provide information via various devices such as a mouse, a roller ball, a touchpad, a keypad, a keyboard, a touch screen, a pen and/or voice activation, a body motion detection, for example. Typically, a mechanism such as a push button or the enter key on the keyboard can be employed subsequent entering the information in order to initiate the search. However, it is to be appreciated that the claimed subject matter is not so limited. For example, merely highlighting a check box can initiate information conveyance. In another example, a command line interface can be employed. For example, the command line interface can prompt (e.g., via text rendered on a display and/or an audio tone) the user for information via providing a text message. The user can then provide suitable information, such as alpha-numeric input corresponding to an option provided in the interface prompt or an answer to a question posed in the prompt. It is to be appreciated that the command line interface can be employed in connection with a GUI and/or API. In addition, the command line interface can be employed in connection with hardware (e.g., video cards) and/or displays (e.g., black and white, EGA, VGA, SVGA, etc.) with limited graphic support, and/or low bandwidth communication channels.
The surface computing environment 104 can further employ a data store 506. The data store 506 can be utilized to retain user profiles employed to verify authentication information, user data, application data, operating system data and the like. It is to be appreciated that the data store 506 can be, for example, either volatile memory or nonvolatile memory, or can include both volatile and nonvolatile memory. By way of illustration, and not limitation, nonvolatile memory can include read only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), or flash memory. Volatile memory can include random access memory (RAM), which acts as external cache memory. By way of illustration and not limitation, RAM is available in many forms such as static RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), Synchlink DRAM (SLDRAM), Rambus direct RAM (RDRAM), direct Rambus dynamic RAM (DRDRAM), and Rambus dynamic RAM. The data store 506 of the subject systems and methods is intended to comprise, without being limited to, these and any other suitable types of memory. In addition, it is to be appreciated that the data store 506 can be a server, a database, a hard drive, a pen drive, an external hard drive, a portable hard drive, and the like.
According to an aspect, the authentication object can be obtained automatically, manually, and/or by request. For instance, the authentication information can be obtained when the authentication object enters the surface computing environment and/or traverses within a predetermined range from surface computing equipment (e.g., table, wall, desk, etc.) that acts as a display for user interactions. In addition, the authentication information can be conveyed automatically to the surface when a user interacts (e.g., touches) with the surface while carrying the authentication object retaining the authentication information. Pursuant to another illustration, the authentication information can be conveyed manually by a user. For example, a user can place the authentication object on a surface and initiate transfer according to one or mechanisms (e.g., light modulation, vibration modulation, capacitance modulation, text messaging, near field communications, and the like) described previously. In addition, authentication information can be conveyed in response to a request. For example, the surface can request authentication information upon receiving user input for a first time.
At reference numeral 604, the obtained authentication information is analyzed. For instance, the surface can verify the authentication information against a user profile, user account, network service and the like. In addition, the authentication information can include login information to enable a user to login to the surface.
At reference numeral 606, the authentication information is associated with a user/device pairing. For instance, the authentication information can identify a user and a user's authentication object. The association can facilitate verification of authorized input from the user based at least in part on the authentication object, data from the authentication object and/or a location of the authentication object.
At reference numeral 704, a location of the touch point is determined. According to an aspect, touch points can be created by inductance and/or capacitance. The surface can include an inductance or capacitance array that can provide a location of a touch point on the surface. At reference numeral 706, a location of an authenticated device is ascertained. For example, a device such as a mobile device, electronic device, jewelry item and so forth can be an authentication object that includes authentication information conveyed to the surface as described supra. Pursuant to an illustration, the location of the device can be determined via optical and/or physical observations. For instance, the device can be placed on the surface. In addition, a location can be determined via near field communications between the surface and the device.
At reference numeral 708, it is determined if the obtained touch point originates from an authenticated user or is otherwise authenticated. For example, the touch point can include an embedded RF signal that includes encoded authentication information. The RF signal can modulate a capacitance received by a surface when a touch point is generated. The surface can extract the authentication information to determine if the input is valid. According to another aspect, the determined location of the authenticated device can be employed to create an authenticated region or area on the surface. A touch point within the region is determined to be authenticated in accordance with the authentication information included on the authenticated device.
