The example method then includes determining that the requester is in an approved list of requestors and granting access to the content item. In one variation, the request to access the content item includes activation of a shared link. In another variation, the request to access the content item includes access to a shared folder in the synchronized online content management system. In a third variation, determining that the requester is in an approved list of requesters includes determining that the requester is logged into a primary and secondary account, and that the requester is in an approved list for the secondary account.

Description

TECHNICAL FIELD

The present technology pertains to online content management systems and more specifically pertains to controlling access to shared content in a content management system.

BACKGROUND

Online content management systems allow a user to upload content to such a system and access the uploaded content from any device. One advantage of such a system is that once the content is uploaded, the content is stored in a cloud server and thus is not subject to being lost in the event of failure of any individual device memory or storage mechanism. Another advantage of such a system is that a user can quickly and easily share large files with multiple other users. For example, a user can upload a large content item such as a high-resolution video to the content management system. Once the video is uploaded the user can give a second user read-write access to the content item by granting the second user shared folder access. Similarly, the user can give read-only access to the content item by sending a third user a network address associated with the content item. In this case, the third user does not even need to be a member of the content management system to access the content item.

Groups such as businesses, universities, and schools can utilize an account for a content management system to allow members of the group to upload, share, and collaborate on uploaded content items. However, in such systems there exists the possibility that a member of the group might inadvertently or otherwise share sensitive confidential data with external unauthorized users. Thus a need exists for enabling an administrator of a group account to limit sharing of content outside of the group and to provide more control for how group members share content.

SUMMARY

Disclosed are systems, methods, and non-transitory computer-readable storage media for controlling access to shared content in an online content management system. An example method includes receiving a request to access a content item from a requestor, wherein the content item is stored in a synchronized online content management system. The example method then includes determining that the requestor is in an approved list of requestors and granting access to the content item. In one variation of the example method, the request to access the content item includes activation of a shared link. In another variation of the example method, the request to access the content item includes access to a shared folder in the synchronized online content management system.

In a third variation of the example method, determining that the requestor is in an approved list of requestors includes determining that the requestor is logged into a primary and secondary account, and that the requestor is in an approved list for the secondary account. In a fourth variation of the example method, the method includes prompting the user to login to the secondary account.

A second example method allows an administrator of a group account to control types of shared links that each user in the group can create. The second example method includes, receiving a request from a requestor to perform a predefined action, wherein the predefined action is sharing a link to a folder or sharing access to a folder in a synchronized online content management system. The second example method includes determining that the requestor is in a predefined group and determining a setting for the predefined group, wherein the setting is always public, always private, or allowing the requestor to specify public or private. The second example method then includes performing the predefined action according to the setting.

In a first variation, the second example method can include receiving a list of recipients to perform the predefined action with and displaying users to which the first action can be performed in a first configuration and displaying users to which the first action cannot be performed in a second configuration.

DETAILED DESCRIPTION

Various embodiments of the disclosure are discussed in detail below. While specific implementations are discussed, it should be understood that this is done for illustration purposes only. A person skilled in the art will recognize that other components and configurations may be used without departing from the spirit and scope of the disclosure.

The disclosed technology addresses the need in the art for enabling an administrator of a group account of an online content management system to limit sharing of content outside of the group and to provide more control for how group members share content. An example method includes receiving a request to access a content item from a requestor, wherein the content item is stored in a synchronized online content management system. The example method then includes determining that the requestor is in an approved list of requestors and granting access to the content item. In one variation of the example method, the request to access the content item includes activation of a shared link. In another variation of the example method, the request to access the content item includes access to a shared folder in the synchronized online content management system.

In a third variation of the example method, determining that the requestor is in an approved list of requestors includes determining that the requestor is logged into a primary and secondary account, and that the requestor is in an approved list for the secondary account. In a fourth variation of the example method, the method includes prompting the user to login to the secondary account.

A second example method allows an administrator of a group account to control types of shared links that each user in the group can create. The second example method includes receiving a request from a requestor to perform a predefined action, wherein the predefined action is sharing a link to a folder or sharing access to a folder in a synchronized online content management system. The second example method includes determining that the requestor is in a predefined group and determining a setting for the predefined group, wherein the setting is always public, always private, or allowing the requestor to specify public or private. The second example method then includes performing the predefined action according to the setting.

In a first variation, the second example method can include receiving a list of recipients to perform the predefined action with and displaying users to which the first action can be performed in a first configuration and displaying users to which the first action cannot be performed in a second configuration.

An exemplary system configuration 100 is shown in FIG. 1, wherein electronic devices communicate via a network for purposes of exchanging content and other data. System 100 can be configured for use on a wide area network such as that illustrated in FIG. 1. However, the present principles are applicable to a wide variety of network configurations that facilitate the intercommunication of electronic devices, such as a local area network, wireless network, etc. For example, each of the components of system 100 in FIG. 1 can be implemented in a localized or distributed fashion in a network.

In system 100, a user can interact with content management system 106 through any one of a variety of client devices 102₁, 102₂, . . . , 102_n (collectively “102”) connected to network 104 by direct and/or indirect communication. Content management system 106 can support connections from a variety of different client devices, such as desktop computers; mobile computers; mobile communications devices, e.g. mobile phones, smart phones, tablets; smart televisions; set-top boxes; and/or any other network enabled computing devices. Client devices 102 can be of varying type, capabilities, operating systems, etc. Furthermore, content management system 106 can concurrently accept connections from and interact with multiple client devices 102.

A user can interact with content management system 106 via a client-side application installed on client device 102_i. In some embodiments, the client-side application can include a content management system specific component. For example, the component can be a stand-alone application, one or more application plug-ins, and/or a browser extension. However, the user can also interact with content management system 106 via a third-party application, such as a web browser, that resides on client device 102_i and is configured to communicate with content management system 106. In either case, the client-side application can present a user interface (UI) for the user to interact with content management system 106. For example, the user can interact with the content management system 106 via a client-side application integrated with the file system or via a webpage displayed using a web browser application.

Content management system 106 can make it possible for a user to store content, as well as perform a variety of content management tasks, such as retrieve, modify, browse, and/or share the content. Furthermore, content management system 106 can make it possible for a user to interact with the content management system through multiple client devices 102. For example, a user may upload content to content management system 106 using client device 102_i via network 104. The user can later retrieve the uploaded content from content management system 106 using the same client device 102_i or some other client device 102_j.

To facilitate the various content management services, a user can create an account with content management system 106. The account information can be maintained in user account database 150. User account database 150 can store profile information for registered users. In some cases, the only personal information in the user profile can be a username and/or email address. However, content management system 106 can also be configured to accept additional user information.

User account database 150 can also include account management information, such as account type, e.g. free or paid; usage information, e.g. file edit history; maximum storage space authorized; storage space used; content storage locations; security settings; personal configuration settings; content sharing data; etc. Account management module 124 can be configured to update and/or obtain user account details in user account database 150. The account management module 124 can be configured to interact with any number of other modules in content management system 106.

An account can be used to store content, such as documents, text files, audio files, video files, etc., from one or more client devices 102 authorized on the account. The content can also include folders of various types with different behaviors, or other mechanisms of grouping content items together. For example, an account can include a public folder that is accessible to any user. The public folder can be assigned a web-accessible address. A link to the web-accessible address can be used to access the contents of the public folder. In another example, an account can include a photos folder that is intended for photos and that provides specific attributes and actions tailored for photos; an audio folder that provides the ability to play back audio files and perform other audio related actions; or other special purpose folders. An account can also include shared folders or group folders that are linked with and available to multiple user accounts. The permissions for multiple users may be different for a shared folder.

The content can be stored in content storage 160. Content storage 160 can be a storage device, multiple storage devices, or a server. Alternatively, content storage 160 can be a cloud storage provider or network storage accessible via one or more communications networks. Content management system 106 can hide the complexity and details from client devices 102 so that client devices 102 do not need to know exactly where the content items are being stored by content management system 106. In one variation, content management system 106 can store the content items in the same folder hierarchy as they appear on client device 102_i. However, content management system 106 can store the content items in its own order, arrangement, or hierarchy. Content management system 106 can store the content items in a network attached storage (NAS) device, in a storage area network (SAN), in a redundant array of independent disks (RAID), etc. Content storage 160 can store content items using one or more partition types, such as FAT, FAT32, NTFS, EXT2, EXT3, EXT4, ReiserFS, BTRFS, and so forth.

Content storage 160 can also store metadata describing content items, content item types, and the relationship of content items to various accounts, folders, or groups. The metadata for a content item can be stored as part of the content item or can be stored separately. In one variation, each content item stored in content storage 160 can be assigned a system-wide unique identifier.

Content storage 160 can decrease the amount of storage space required by identifying duplicate files or duplicate segments of files. Instead of storing multiple copies, content storage 160 can store a single copy and then use a pointer or other mechanism to link the duplicates to the single copy. Similarly, content storage 160 can store files more efficiently, as well as provide the ability to undo operations, by using a file version control that tracks changes to files, different versions of files (including diverging version trees), and a change history. The change history can include a set of changes that, when applied to the original file version, produce the changed file version.

Content management system 106 can be configured to support automatic synchronization of content from one or more client devices 102. The synchronization can be platform agnostic. That is, the content can be synchronized across multiple client devices 102 of varying type, capabilities, operating systems, etc. For example, client device 102_i can include client software, which synchronizes, via a synchronization module 132 at content management system 106, content in client device 102_i's file system with the content in an associated user account. In some cases, the client software can synchronize any changes to content in a designated folder and its sub-folders, such as new, deleted, modified, copied, or moved files or folders. The client software can be a separate software application, can integrate with an existing content management application in the operating system, or some combination thereof. In one example of client software that integrates with an existing content management application, a user can manipulate content directly in a local folder, while a background process monitors the local folder for changes and synchronizes those changes to content management system 106. Conversely, the background process can identify content that has been updated at content management system 106 and synchronize those changes to the local folder. The client software can provide notifications of synchronization operations, and can provide indications of content statuses directly within the content management application. Sometimes client device 102_i may not have a network connection available. In this scenario, the client software can monitor the linked folder for file changes and queue those changes for later synchronization to content management system 106 when a network connection is available. Similarly, a user can manually stop or pause synchronization with content management system 106.

A user can also view or manipulate content via a web interface generated and served by user interface module 122. For example, the user can navigate in a web browser to a web address provided by content management system 106. Changes or updates to content in the content storage 160 made through the web interface, such as uploading a new version of a file, can be propagated back to other client devices 102 associated with the user's account. For example, multiple client devices 102, each with their own client software, can be associated with a single account and files in the account can be synchronized between each of the multiple client devices 102.

Content management system 106 can include a communications interface 120 for interfacing with various client devices 102, and can interact with other content and/or service providers 109₁, 109₂, . . . , 109_n (collectively “109”) via an Application Programming Interface (API). Certain software applications can access content storage 160 via an API on behalf of a user. For example, a software package, such as an app on a smartphone or tablet computing device, can programmatically make calls directly to content management system 106, when a user provides credentials, to read, write, create, delete, share, or otherwise manipulate content. Similarly, the API can allow users to access all or part of content storage 160 through a web site.

Content management system 106 can also include authenticator module 126, which can verify user credentials, security tokens, API calls, specific client devices, and so forth, to ensure only authorized clients and users can access files. Further, content management system 106 can include analytics module 134 that can track and report on aggregate file operations, user actions, network usage, total storage space used, as well as other technology, usage, or business metrics. A privacy and/or security policy can prevent unauthorized access to user data stored with content management system 106.

Content management system 106 can include sharing module 130 for managing sharing content publicly or privately. Sharing content publicly can include making the content item accessible from any computing device in network communication with content management system 106. Sharing content privately can include linking a content item in content storage 160 with two or more user accounts so that each user account has access to the content item. The sharing can be performed in a platform agnostic manner. That is, the content can be shared across multiple client devices 102 of varying type, capabilities, operating systems, etc. The content can also be shared across varying types of user accounts.

In some embodiments, content management system 106 can include a content management module 128 for maintaining a content directory. The content directory can identify the location of each content item in content storage 160. The content directory can include a unique content entry for each content item stored in the content storage.

A content entry can include a content path that can be used to identify the location of the content item in a content management system. For example, the content path can include the name of the content item and a folder hierarchy associated with the content item. For example, the content path can include a folder or path of folders in which the content item is placed as well as the name of the content item. Content management system 106 can use the content path to present the content items in the appropriate folder hierarchy.

A content entry can also include a content pointer that identifies the location of the content item in content storage 160. For example, the content pointer can include the exact storage address of the content item in memory. In some embodiments, the content pointer can point to multiple locations, each of which contains a portion of the content item.

In addition to a content path and content pointer, a content entry can also include a user account identifier that identifies the user account that has access to the content item. In some embodiments, multiple user account identifiers can be associated with a single content entry indicating that the content item has shared access by the multiple user accounts.

To share a content item privately, sharing module 130 can be configured to add a user account identifier to the content entry associated with the content item, thus granting the added user account access to the content item. Sharing module 130 can also be configured to remove user account identifiers from a content entry to restrict a user account's access to the content item.

To share content publicly, sharing module 130 can be configured to generate a custom network address, such as a uniform resource locator (URL), which allows any web browser to access the content in content management system 106 without any authentication. To accomplish this, sharing module 130 can be configured to include content identification data in the generated URL, which can later be used to properly identify and return the requested content item. For example, sharing module 130 can be configured to include the user account identifier and the content path in the generated URL. Upon selection of the URL, the content identification data included in the URL can be transmitted to content management system 106 which can use the received content identification data to identify the appropriate content entry and return the content item associated with the content entry.

In addition to generating the URL, sharing module 130 can also be configured to record that a URL to the content item has been created. In some embodiments, the content entry associated with a content item can include a URL flag indicating whether a URL to the content item has been created. For example, the URL flag can be a Boolean value initially set to 0 or false to indicate that a URL to the content item has not been created. Sharing module 130 can be configured to change the value of the flag to 1 or true after generating a URL to the content item.

In some embodiments, sharing module 130 can also be configured to deactivate a generated URL. For example, each content entry can also include a URL active flag indicating whether the content should be returned in response to a request from the generated URL. For example, sharing module 130 can be configured to only return a content item requested by a generated link if the URL active flag is set to 1 or true. Thus, access to a content item for which a URL has been generated can be easily restricted by changing the value of the URL active flag. This allows a user to restrict access to the shared content item without having to move the content item or delete the generated URL Likewise, sharing module 130 can reactivate the URL by again changing the value of the URL active flag to 1 or true. A user can thus easily restore access to the content item without the need to generate a new URL.

While content management system 106 is presented with specific components, it should be understood by one skilled in the art, that the architectural configuration of system 106 is simply one possible configuration and that other configurations with more or less components are also possible.

FIG. 2 shows example graphical user interface 200 to enable an administrator of a group account on a content management system to manage sharing permissions for members of the group. Graphical user interface 200 includes Sharing Icon 202. Under Sharing Icon 202, Folder Privacy Settings 204 and Link Privacy Settings 222 are provided.

Folder Privacy Settings 204 enable an administrator to generally allow folders in the group account to be shared with users outside of the group. The administrator for example can check a “Yes” setting 206, which will permit content in the group account to be shared with external users. The administrator may require that a warning message be provided to a group member when content is designated by the member to be shared with an external user, such as by checking a “warning” setting 208. Conversely, the administrator may generally prohibit folders in the group account from being shared with external users, for example by checking a “No” setting 210 in the Folder Privacy Settings 204.

Link Privacy Settings 222 enables an administrator to determine how group members are permitted to specify privacy settings for links to specific content folders. Setting 216 permits each member of a group to select a level of privacy for a specific link to content, such as public or private (i.e. limited to group members only). Setting 218 sets a default user selection as group members only, but allows members to change the privacy of the link to public. Setting 220 allows members of the group to only view a shared link, thus making each shared link private.

FIG. 3 shows example database 300 for storing and looking up user IDs 302 and team IDs 305. As shown, database 300, in response to a query, can return whether a UserID is present and can return an indication of the team or group of which a UserID is a member. Database 300 can be any database capable of returning data in response to a query, such as a SQL structured database. One of ordinary skill in the art will recognize that other databases can be utilized as well. As shown in example database 300, a first group (1) has four members with unique UserID values (1, 2, 3 and 4) and a second group (2) has three members with unique UserID values (5, 6 and 7). According to one aspect of the invention, the system determines whether a requester is registered with the content management system (i.e. is logged-in to a first account) and then further determines whether the requester is a member of a shared group (i.e. is logged-in to a secondary account).

FIG. 4 shows example database 400 for storing and looking up stored group policies for various sharing functions in the content management system. Example database 400 includes Shared Folder functions 402, with three options 406 shown. As shown, an administrator has selected a second option from options 406. In one example, options 406 correspond to options 206, 208 and 210 in Folder Privacy Settings 204 described above with respect to FIG. 2.

Example database 400 also includes Shared Link functions 404, with three options 408 shown. As shown, an administrator has selected a third option from options 408. In one example, options 408 correspond to options 216, 218 and 220 in Link Privacy Settings 222 described above in FIG. 2. Database 400 can be any database capable of returning data in response to a query, such as a SQL structured database. One of ordinary skill in the art will recognize that other databases can be utilized as well.

FIG. 5 shows method 500 for permitting access to a shared link, in the form of a process flow. At step 502, a request is received from a requester to access a content item that is stored in a synchronized online content management system. At step 504, it is determined that the requester's ID is in an approved list of requesters, and then step 506 is executed granting access to the content item. This determination can include querying a structured database such as the one shown in FIG. 3 or FIG. 4.

In one variation of the method 500, the request to access the content item includes activation of a shared link. In another variation of method 500, the request to access the content item includes access to a shared folder in the synchronized online content management system.

In a third variation of method 500, determining that the requestor is in an approved list of requestors includes determining that the requestor is logged into a primary and secondary account, and that the requestor is in an approved list for the secondary account. In a fourth variation of the method 500, the method includes prompting the user to login to the secondary account. In one example, this feature can utilize single sign-on (SSO) technology that allows a user to sign into a personal and work account simultaneously and switch between the two accounts.

FIG. 6 shows method 600 for allowing an administrator of a group account to control types of shared links that each user in the group can create. Method 600 begins at step 602 and includes, receiving a request from a requester to perform a predefined action, wherein the predefined action is sharing a link to a folder or sharing access to a folder in a synchronized online content management system. Method 600 then proceeds to step 604 and includes determining that the requester's ID is in a predefined group and determining a setting for the content folders in the predefined group, wherein the setting is always public, always private, or allowing the requester to specify public or private. Method 600 then proceeds to step 606 and includes performing the predefined action according to the retrieved setting.

In a first variation, method 600 can include receiving a list of recipients to perform the predefined action with and displaying users to which the first action can be performed in a first configuration and displaying users to which the first action cannot be performed in a second configuration. In one example, if a requester specifies public, names within a same group are identified with a first color such as green and names not within the group are identified with a second color such as red to warn the requestor of links being sent to names not within the group. Similarly, if the requester specifies private, names within the same group are identified with a first color such as green and names not within the group are identified with a second color such as red to show the requestor link recipients that will be sent and link recipients that will be blocked by current settings. These examples are merely illustrative and one of ordinary skill in the art will recognize that other indicators can be used in various circumstances.

FIG. 7A, and FIG. 7B show exemplary possible system embodiments. The more appropriate embodiment will be apparent to those of ordinary skill in the art when practicing the present technology. Persons of ordinary skill in the art will also readily appreciate that other system embodiments are possible.

FIG. 7A shows a conventional system bus computing system architecture 700 wherein the components of the system are in electrical communication with each other using a bus 705. Exemplary system 700 includes a processing unit (CPU or processor) 710 and a system bus 705 that couples various system components including the system memory 715, such as read only memory (ROM) 720 and random access memory (RAM) 725, to the processor 710. The system 700 can include a cache of high-speed memory connected directly with, in close proximity to, or integrated as part of the processor 710. The system 700 can copy data from the memory 715 and/or the storage device 730 to the cache 712 for quick access by the processor 710. In this way, the cache can provide a performance boost that avoids processor 710 delays while waiting for data. These and other modules can control or be configured to control the processor 710 to perform various actions. Other system memory 715 may be available for use as well. The memory 715 can include multiple different types of memory with different performance characteristics. The processor 710 can include any general purpose processor and a hardware module or software module, such as module 1732, module 2734, and module 3736 stored in storage device 730, configured to control the processor 710 as well as a special-purpose processor where software instructions are incorporated into the actual processor design. The processor 710 may essentially be a completely self-contained computing system, containing multiple cores or processors, a bus, memory controller, cache, etc. A multi-core processor may be symmetric or asymmetric.

To enable user interaction with the computing device 700, an input device 745 can represent any number of input mechanisms, such as a microphone for speech, a touch-sensitive screen for gesture or graphical input, keyboard, mouse, motion input, speech and so forth. An output device 735 can also be one or more of a number of output mechanisms known to those of skill in the art. In some instances, multimodal systems can enable a user to provide multiple types of input to communicate with the computing device 700. The communications interface 740 can generally govern and manage the user input and system output. There is no restriction on operating on any particular hardware arrangement and therefore the basic features here may easily be substituted for improved hardware or firmware arrangements as they are developed.

Storage device 730 is a non-volatile memory and can be a hard disk or other types of computer readable media which can store data that are accessible by a computer, such as magnetic cassettes, flash memory cards, solid state memory devices, digital versatile disks, cartridges, random access memories (RAMs) 725, read only memory (ROM) 720, and hybrids thereof.

The storage device 730 can include software modules 732, 734, 736 for controlling the processor 710. Other hardware or software modules are contemplated. The storage device 730 can be connected to the system bus 705. In one aspect, a hardware module that performs a particular function can include the software component stored in a computer-readable medium in connection with the necessary hardware components, such as the processor 710, bus 705, display 735, and so forth, to carry out the function.

FIG. 7B shows a computer system 750 having a chipset architecture that can be used in executing the described method and generating and displaying a graphical user interface (GUI). Computer system 750 is an example of computer hardware, software, and firmware that can be used to implement the disclosed technology. System 750 can include a processor 755, representative of any number of physically and/or logically distinct resources capable of executing software, firmware, and hardware configured to perform identified computations. Processor 755 can communicate with a chipset 760 that can control input to and output from processor 755. In this example, chipset 760 outputs information to output 765, such as a display, and can read and write information to storage device 770, which can include magnetic media, and solid state media, for example. Chipset 760 can also read data from and write data to RAM 775. A bridge 780 for interfacing with a variety of user interface components 785 can be provided for interfacing with chipset 760. Such user interface components 785 can include a keyboard, a microphone, touch detection and processing circuitry, a pointing device, such as a mouse, and so on. In general, inputs to system 750 can come from any of a variety of sources, machine generated and/or human generated.
