GB2501005A - Limiting the number of devices with which a user can synchronise data in a cloud storage account - Google Patents

Abstract

A user device sends a login request to a cloud based service. The request includes user details and a device identifier. The device identifier may be a CPU identifier. The service determines whether the device is currently authorised to synchronise with the users account. The service may compare the device identifier with a list of identifiers of devices that have already been authorised. If the device has been authorised, synchronisation with the device is enabled. Otherwise, the service determines whether the limit on the number of devices allowed to synchronise with the account has been reached. If not, the device is added to a list of authorised devices and synchronisation with the device is enabled. Otherwise, synchronisation is disabled. The service may send the device an authentication token, if synchronisation is enabled. Each account may have a different limit on the number of devices.

[00191 FIG. I illustrates an example diagram of a system having a host server 100 of a cloud service and/or cloud storage accounts with device pinning capabilities to control content access such as content synchronization.

[00201 The client devices 102 can be any system and/or device, and/or any combination of devices/systems that is able to establish a connection, including wired, wireless, cellular connections with another device, a server and/or other systems such as host sewer 100 and/or notification server 150. Client devices 102 will typically include a display and/or other output functionalities to present information and data exchanged between among the devices 102 and/or the host server 100 and/or notification server 50.

[00211 For example, the client devices 102 can include mobile, hand held or portable devices or non-portable devices and can be any of, but not limited to, a server desktop, a desktop computer, a computer cluster, or portable devices including, a notebook, a laptop computer, a handhcld computer, a palmtop computer, a mobile phone, a cell phone, a smart phone, a PDA, a Blackberry device, a Treo, a handhelcl tablet (e.g. an iPad, a Galaxy, Xoom Tablet, etc.), a tablet PC, a thin-client, a hand held console, a hand held gaming device or console, an iPhone, and/or any other portable, mobile, hand held devices, etc. running on any platform or any operating system (e.g., Mac-based OS (OS X, iOS, etc.), Windows-based OS (Windows Mobile, Windows 7, etc.), Android, Blackberry OS, Embedded Linux platforms, Palm OS, Symbian platform. In onc embodiment, the clicnt devices 102, host sewer 100, and app server are coupled via a network 106 and/or a netDrk 108. In some embodiments, the devices 102 and host server 100 may be directly connected to one another.

[00221 The input mechanism on client devices 102 can include touch screen keypad (including single touch, multi-touch, gesture sensing in 2D or 3D, etc.), a physical keypad, a mouse, a pointer, a track pad, motion detector (e.g., including 1-axis, 2-axis, 3-axis accelerometer, etc.), a light sensor, capacitance sensor, resistance sensor, temperature sensor, proximity sensor, a piezoelectric device, device orientation detector (e.g., electronic compass, tilt sensor, rotation sensor, gyroscope, accelerometer), or a combination of the above.

[00231 Signals received or detected indicating user activity at client devices 102 through one or more of the above input mechanism, or others, can be used in the disclosed technology by various users or collaborators (e.g., collaborators 108) for accessing, through network 106, a web-based collaboration environment or online collaboration platform (e.g., hosted by the host server 100).

[00241 The collaboration platform or environment hosts workspaces with work items that one or more users can access (e.g., view, edit, update, revise, comment, download, preview, tag, or otherwise manipulate, etc.). A work item can generally include any type of digital or electronic content that can be viewed or accessed via an electronic device (e.g., device 102). The digital content can include.pdf files, .doc, slides (e.g., Powerpoint slides), images, audio files, multimedia content, web pages, blogs, etc. A workspace can generally refer to any grouping of a set of digital content in the collaboration platform. The grouping can be created, identified, or specified by a user or through other means. This user may be a creator user or administrative user, for

example.

100251 In general, a workspace can be associated with a set of users or collaborators (e.g., collaborators 108) which have access to the content included therein. The levels of access (e.g., based on permissions or Riles) of each user or collaborator to access the content in a given workspace may be the same or may vary among the users. Each user may have their own set of access rights to every piece of content in the workspace, or each user may be different access rights to different pieces of content. Access rights may be specified by a user associated with a work space and/or a user who created/uploaded a particular piece of content to the workspace, or any other designated user or collaborator.

[00261 In general, the collaboration platform allows multiple users or collaborators to access or collaborate efforts on work items such each user can see, remotely, edits, revisions, comments, or annotations being made to specific work items through their own user devices. For example, a user can upload a document to a work space for other users to access (e.g., for viewing, editing, commenting, signing-off or otherwise manipulating). The user can login to the online platform and upload the document (or any other type of work item) to an existing work space or to a new work space. The document can be shared with existing users or collaborators in a work space.

[00271 A diagranmiatic illustration of the online collaboration environment and the relationships between workspaces and users/collaborators are illustrated with further reference to the example of FIG. 2. A diagrammatic illustration of a workspace having multiple work items with which collaborators can access through multiple devices is illustrated with further reference to the example of FIG. 3.

[00281 In one embodiment, the host server 100 of cloud-based services and/or cloud storage such as an online or web-based collaboration environment is able to track or monitor the devices used by users to access content or activities.

[00291 Functions and techniques disclosed for device pinning for cloud-based services and storage accounts hosted by server 100 are illustrated further in the example of FIG. 5. Functions and techniques performed by the host server 100 and/or other related components therein are described, respectively, in detail with further reference to the example flow charts of FIGS. 6-7.

[00301 In one embodiment, client devices 102 communicate with the host server and/or notification sewer 150 over network 106. In general, network 106, over which the client devices 102, the host sewer 100, and/or notification server 150 communicate, may be a cellular network, a telephonic network, an open network, such as the Internet, or a private network, such as an intranet and/or the extranet, or any combination thereof. For example, the Internet can provide file transfer, remote log in, email, news, RSS, cloud-based services, instant messaging, visual voicemail, push mail, VoIP, and other services through any known or convenient protocol, such as, but is not limited to the TCP/IP protocol, Open System Interconnections (OSI), FTP, UPnP, iSCSI, NSF, ISDN, PDH, RS-232, SDH, SONET, etc. [00311 The network 106 can be any collection of distinct networks operating wholly or partially in conjunction to provide connectivity to the client devices 102 and the host sewer 100 and may appear as one or more networks to the serviced systems and devices. In one embodiment, communications to and from the client devices 102 can be achieved by, an open network, such as the Internet, or a private network, such as an intranet and/or the extranet. In one embodiment, communications can be achieved by a secure communications protocol, such as secure sockets layer (SSL), or transport layer security (TLS).

[00321 In addition, communications can be achieved via one or more networks, such as. but are not limited to, one or more of WiMax, a Local Area Network (LAN), Wireless Local Area Network (V/LAN), a Personal area network (PAN), a Campus area network (CAN), a Metropolitan area network (MAN), a Wide area network (WAN), a Wireless wide area network (WWAN), enabled with technologies such as, by way of cxampk, Goba] System for Mobile Communications (USM), Personal Communications Service (PCS), Digital Advanced Mobile Phone Service (D-Arnps), Bluetooth, Wi-Fi, Fixed Wireless Data, 20, 2.50, 30, 40, IMT-Advanced, pre-4G, 30 LTE, 3GPP LTE, LTE Advanced, mobile WiMax, WiMax 2, WirelessMAN-Advanced networks, enhanced data rates for GSM evolution (EDGE), General packet radio service (GPRS), enhanced GPRS, iBurst, UMTS, HSPDA, HSLTPA, HSPA, UMTS-TDD, xRTT, EV-DO, messaging protocols such as, TCP/TP, SMS, MMS, extensible messaging and presence protocol (XMPP), real time messaging protocol (RTMP), instant messaging and presence protocol 1MPP), instant messaging, USSD, IRC, or any other wireless data networks or messaging protocols.

100331 FIG. 2 depicts a diagram of a web-based or online collaboration platform deployed in an enterprise or other organizational setting 250 for organizing work items 215, 235, 255 and workspaces 205, 225, 245, as one example of a hosted cloud service and/or cloud storage with dcviec pinning capabilities.

[00341 The web-based platform for collaborating on projects or jointly working on documents can be used by individual users and shared among collaborators. In addition, the collaboration platform can be deployed in an organized setting including but not limited to, a company (e.g., an enterprise setting), a department in a company, an academic institution, a department in an academic institution, a class or course setting, or any other types of organizations or organized setting.

[00351 When deployed in an organizational setting, multiple workspaccs (e.g., workspace A, B C) can be created to support different projects or a variety of work flows. Each workspace can have its own associate work items. For example, work space A 205 may be associated with work items 215, work space B 225 can be associated with work items 235, and work space N can be associated with work items 255. The work items 215, 235, and 255 may be unique to each work space but need not be. For example, a particular word document can be associated with only one work space (e.g., work space A 205) or it may be associated with multiple work spaces (e.g., Work space A 205 and work space B 225, etc.).

100361 In general, each work space has a set of users or collaborators associated with it. For example, work space A 205 is associated with multiple users or collaborators 206. In some instances, work spaces deployed in an enterprise may be department specific. For example, work space B may be associated with department 210 and some users shown as example user A 208 and workspace N 245 can be associated with departments 212 and 216 and users shown as example user B 214.

[00371 Each user associated with a work space can generally access the work items associated with the work space. The level of access will depend on permissions associated with the specific work space, and/or with a specific work item. Permissions can be set for the work space or set individually on a per work item basis. For example, the creator of a work space (e.g., one of user A 208 who creates work space B) can set one permission setting applicable to all work items 235 for other associated users and/or users associated with the affiliate department 210, for example. Creator user A 208 may also set different permission settings for each work item, which may be the same for different users, or varying for different users.

[00381 Tn each work space A, B... N, when an action is performed on a work item by a given user or ally other activity is detected in the work space, other users in the same work space may be notified (e.g., in real time or in near real time, or not in real time). Activities which frigger real time notifications can include, by way of example but not limitation, adding, deleting, or modifying collaborators in the work space, uploading, downloading, adding, deleting a work item in the work space, creating a discussion topic in the work space.

[00391 Specifically, items or content downloaded or edited in accordance with the techniques described in the present disclosure can be cause notifications to be generated. Such notifications can be sent to relevant users to notify them of actions surrounding a download, an edit, a change, a modification, a new file, a conflicting version, an upload of an edited or modified file.

[00401 Tn one embodiment, in a user interface to the web-based collaboration platform where notifications are presented, users can, via the same interface, create action items (e.g., tasks) and delegate the action items to other users including collaborators pertaining to a work item 215, for example. The collaborators 206 may be in the same workspace A 205 or the user may include a newly invited collaborator.

Similarly, in the same user interface where discussion topics can be created in a work space (e.g., work space A, B or N, etc.), actionable events on work items can be created and/or delegated/assigned to other users such as collaborators of a given work spacc 206 or other users. Through the same user interface, task status and updates from multiple users or collaborators can be indicated and reflected. In some instances, the users can perform the tasks (e.g., review or approve or reject, ctc.) via the same user interface.

[00411 FIG. 3 depicts an example diagram of a workspace 302 in an online or web-based collaboration environment accessible by multiple collaborators 322 through various devices authorized to access the work space.

[00421 Each of users 316, 318, and 320 can individually usc multiple different devices to access and/or manipulate work items 324 in the work space 302 with which they are associated with. For example users 316, 318, 320 can be collaborators on a project to which work items 324 are relevant. Since the work items 324 are hosted by the collaboration environment (e.g., a cloud-based environment), each user can access the work items 324 anytime, and from any physical location using any device (e.g., including devices they own or any shared/public/loaner device).

[00431 Work items to be edited or viewed can be accessed from the workspace 302 in accordance with the platform and/or application independent mechanisms. Users can also be notified of access, edit, modification, and/or upload related-actions performed on work items 324 by other users or any other types of activities detected in the work space 302. For example, if user 316 modifies a document, one or both of the othcr collaborators 318 and 320 can be notified of the modification in real time, or near real-time, or not in real time. The notifications can be sent through any of all of the devices associated with a given user, in various formats including, one or more of, email, SMS, or via a pop-up window in a user interface in which the user uses to access the collaboration platform. In the event of multiple notifications, each notification can be depicted preferentially (e.g., ordering in the user interface) based on user preferences and/or relevance to the user (e.g., implicit or explicit).

[0044J For example, a notification of a download, access, read, write, edit, or uploaded related activities can be presented in a feed stream among other notifications through a user interface on the user device according to relevancy to the user determined based on current or recent activity of the user in the web-based collaboration environment.

[00451 In one embodiment, a notification feed stream includes updates when an invited user accepts an invitation and/or successfully creates a new account through receipt of an invitation from an existing user. The invited user, upon creation of the new account, receives the account having enhanced features. The new user can automatically be connected to the existing user who sent the invitation. The system can also automatically prompt both users to query they wish to be collaborators in a common work space.

[00461 FIG. 4A depicts an example table 400 monitored/updated by an administrative users to configure/manage devices 404 for users 402 for an enterprise or account that are authorized to synchronize with content stored for the enterprise/account in the cloud-based service/storage account.

[00471 The user and device manager 400 can be used (e.g., accessed via a user interface or console) to track the users 402 in a given enterprise/organization who collaborates or accesses corporate content with various devices. The devices can be tracked/updated using the device list 404 associated with each user. The admin or other authorized user can also set the allowed number of devices 406 via the user/devices manager 400. In some instances, additional information, such as the IP address 406 and/or device authentication date 410 can be stored for each authorized device, or alternatively, for the most recently authorized device or other preferred device.

[00481 FIG. 4B depicts an example table 450 showing a manager 450 for trusted devices 454 for different accounts 452 in the cloud-based service/storage account. The *manager 450 can be accessed (e.g.. via a user interface) by an admin user or other authorized user to view, monitor, or update lists of trusted devices on an account by account basis. Each account may be associated with one enterprise, or they may be affiliated with different enterprises/organizations.

[00491 FIG. 5 depicts a block diagram illustrating an example of components in a host server 500 for cloud-bascd scrvices and storage accounts with dcvicc pinning capability for access and synchronization control.

[00501 Thc host server 500. in one embodiment, hosts a cloud based service and/or cloud based storage service which can include cloud based collaboration andlor file sharing platform. The host server 500 can include, for example, a network interface 502, an account manager 505 having a device number tracking engine 506 and/or a device list manager 507, a security enforcement engine 515 having a device identifier 517 and/or a user identifier, a synchronization manager 535 having an authentication token authorization engine 536 and/or a synchronization engine 537. Additional or less components/modules/engines can be included in the host server 500 and each illustrated component.

100511 The network interface 502 can be a networking module that enables the host server 500 to mediate data in a network with an entity that is external to the host server 500, through any known and/or convenient communications protocol supported by the host and the external entity. The network interface 502 can include one or more of a network adaptor card, a wireless network interface card (e.g., SMS interface, WiFi interface, interfaces for various generations of mobile communication standards including but not limited to 10. 20,30, 3.50,40, LTE, etc.,), Bluetooth, a router, an access point, a wireless router, a switch, a multilayer switch, a protocol converter, a gateway, a bridge, bridge router, a hub, a digital media receiver, and/or a repeater.

[00521 As used herein, a "module," "a manager," a "handler," a "detector," an "interface," a "processor," a "tracker," a "detector," a "generator," a "launcher," a "selector," an "updator," or an "engine" includes a general purpose, dedicated or shared processor and, typically, firmware or software modules that are executed by the processor. Depending upon implementation-specific or other considerations, the module, manager, hander, or engine can be centralized or its functionality distributed.

The module, manager, hander, or engine can include general or special purpose hardware, firmware, or software embodied in a computer-readable (storage) medium for execution by the processor. As used herein, a computer-readable medium or computer-readable storage medium is intended to include all mediums that are statutory (e.g., in the United States, under 35 U.S.C. § 101), and to specifically exclude all mediums that are non-statutory in nature to the extent that the exclusion is necessary for a claim that includes the computer-readable (storage) medium to be valid. Known statutory computer-readable mediums include hardware (e.g., registers, random access memory (RAM, non-v&atile (NV) storage, to name a few), but may or may not be limited to hardware.

[00531 One embodiment of the host server 500 includes the account manager 505 which is able to manage the security policies that govern which and what devices are allowed to synchronize to a given account or with content of a given organization/enterprise. The security policies can include, for example, an allowed number of devices for a user, for any given account/enterprise and/or a list of allowed/authorized devices for a user or for one account/enterprise.

[00541 The device number tracking engine 506 can track, update, cross verify, and/or configure the allotted or allowed number of devices for a user. The allowed numbers can be set by default or configured/reconfigured by a admin user or other user (e.g., IT specialist or security team) with the appropriate rights/permissions. The device list manager 507 can track the list of devices that have been or are authorized for a given user or for a given account (see, for example, the user/device manager table of FIG. 4A and the trusted device manager table of FIG. 411). The trusted devices lists and/or the user/device tracking lists can be stored in repository 530.

[00551 The device list manager 507 can update the list when new devices become authorized or when devices are removed from the list. These updates can be authorized automatically (e.g., as compliant to a set of rules) and/or authorized by a system administrator or other user with appropriate rights. In one embodiment, devices may be added to the authorized list automatically by the device list manager 507 if it is the first device that a user uses to access an account, or any time a user uses a new device and is under the total number of devices allowed for the user. In some instance, any given user can remove an authorized device from being an authorized device such that another device may be added to the trusted devices list by the device list manager 507 (e.g., when the user purchases a new device).

[00561 When a content access or synchronization request is detected by the host sewer 500, the security enforcement engine 5 15 enforces security mechanisms by determining whether the requested device has been authorized or can be authorized.

The request can include a device identifier (e.g.,, CPU ID, or any hardware or software ID uniquely identiring a device) retrieved from a synchronization or mobile client/application which can be used by the engine 515 to determine whether the device has been authorized. The user identifier 518, which can also be included in the access request or synchronization request to identify the associated account/enterprise to determine the relevant security settings (e.g., via the account manager 505).

[00571 Once a requesting device has previously been authorized or can be authorized, the synchronization manager 535 can send device an authentication token (e.g., by the authorization engine 536) to the device on which the sync/mobile application is installed. An authentication token can expire after a certain amount of time, for example, each authorized device can use the granted token for a certain amount of times or over a set period of time for any number of sync/access requests.

Authentication tokens can also be granted until revoked by a user or by the system. The synchronization engine 537 can facilitate content synchronization or access by the authorized device with the host sewer 500.

[00581 FIG. 6 depicts a flow chart illustrating example process flow's for controlling or limiting a number of devices that a user can use to synchronize with a cloud-based service.

[00591 In process 602, a login request to synchronize a device with a cloud-based service from a userjs received. In one example, the cloud-based service enables a collaboration platform (e.g., an online or web-based collaboration platform) that hosts multiple accounts associated with different enterprises or different clients. The cloud-based service can a'so enable/host a cloud-based storage/file sharing service for multiple users and/or for multiple clients which are organization or enterprises. The login request can be sent by a desktop synchronization client associated with the cloud-based service installed on the device. The login request can also be sent by a mobile application associated with the cloud-based service installed on the device (e.g., the device is a smart phone or a tablet or other mobile/portable device).

[00601 In process 606, it is determined whether the device has been previously authorized or registered. Tn one embodiment, whether the device has been authorized can be determined by comparing a device ID of the device with a list of existing device IDs associated with the user. Such a list for a user can be maintained for a specific account or for a specific work space in the cloud-based service. In some instances such a list is maintained for a user for each enterprise or organization with which the user is affiliated in the cloud-service. In general, the device ID includes a CPU ID or other types of hardware identifiers uniquely associated with the device.

[00611 If the device has been authorized, an authentication token is granted in process 616 and synchronization of the device with content associatcd with the account in the cloud-based service is enabled, lithe device has not been previously authorized or registered, in process 608, it is determined whether the number of devices that the user is allowed use for synchronization or other access been reached. In general, the number of devices that the user is allowed to use is specific to one account (e.g., specific to one user account, or one organization/enterprise) ill the cloud-based service and may not be applicable to other accounts. For example, if a user has different accounts in the cloud-service, each account may have its own allowed number of devices.

[00621 The number of devices can be set by an enterprise or organization with which the user's account is affiliated. For example, the allotted number may take upon a default sefting or is set/configured by an administrator user of the account/enterprise or other types of organizations (e.g., the number of devices allowed for any user can be managed on client by client basis or enterprise by enterprise). The number of allowable devices for a given can be updated or changed, for example, responsive to reconfiguration by the administrator user or another user with the appropriate rights/permissions.

100631 If so. in process 620, the device is prohibited from synchronizing with the content associated with the account in the cloud-based service and an error message can be generated in process 622. If the allowed number of devices for the user has not been reached in process 608, the device is then registered in process 610. In process 612, an authentication token is granted and synchronization of the device with content associated with the account in the cloud-based service is enabled in process 614.

100641 FIG. 7 depicts a flow chart illustrating an example process for a synchronization client or mobile application to request content synchronization with a collaboration environment.

[00651 Tn process 702, a synchronization client or mobile application is installed on a device or a synchronization request is detected at a device. A synchronization client can include any software application or module that is able to download content or updates to content managed or stored by a remote server or cloud-based service/storage for a user or enterprise/organization. The synchronization client or mobile application for content synchronization access can generally be installed on any device including mobile devices such as mobile phones, smart phones, and/or tablets.

[00661 For example, the following processes can be automatically performed when the synchronization client or mobile application is first installed or when the application is launched. The processes can also be performed when a request for synchronization or access is initiated by a user or automatically by the client/application.

[00671 Tn process 704, the user is prompted for user credentials and the synchronization client or the mobile application receives user credentials that specific to a given user. The credentials submitted by the user may be specific to one user account used to access work spaces associated with one enterprise or organization. The user may use different sets of user credentials to access multiple work spaces that are affiliated with different enterprises or organizations. Alternatively, one set of user credentials may be used by a user to access all of their accounts with different organizations/enterprises.

[00681 Tn process 706, a device identifier for the device on which the synchronization client is installed is retrieved. The device identifier can include, for example, a CPU ID or other hardware, manufacturer's identifier of the device or any hardware or software components in the device.

[00691 Tn process 708, the synchronization client or mobile application sends the device identifier and user credentials to the collaboration environment. The server hosting the collaboration environment (e.g., or other types of cloud-based services) receives the device identifier and performs an authentication process as described in the flow chart of FIG. 7.

100701 The server or cloud service can also track numbers of devices allowable for synchronization across the accounts in the online collaboration platform and can grant access to synchronization of a device with an account in response to determining that the device has previously been authorized for the account. Each of the accounts can be associated with differcnt enterprise clients serviced by the collaboration platform or other types cloud-services/storage platforms. In general, the access to the account is granted for the device if a number of devices allowable for the account or a user of the account has not been reached or exceeded.

100711 Tn process 710, it is determined whether an authentication has been received, by the device or client. If authorized, in process 712, the synchronization client or mobile application can synchronize the device with content in the collaboration environment. Ifthe device is not authorized, in process 714, an error is generated and synchronization or other access is not allowed. For example, the device is prohibited from synchronizing with the online collaboration platform if a number of devices allowable for the account has been reached or exceeded and the device has not been previously authorized.
