  • Patent number: 11580221
    Abstract: Disclosed are systems, methods, and non-transitory computer-readable storage media for malware detection and content item recovery. For example, a content management system can receive information describing changes made to content items stored on a user device. The content management system can analyze the information to determine if the described changes are related to malicious software on the user device. When the changes are related to malicious software, the content management system can determine which content items are effected by the malicious software and/or determine when the malicious software first started making changes to the user device. The content management system can recover effected content items associated with the user device by replacing the effected versions of the content items with versions of the content items that existed immediately before the malicious software started making changes to the user device.

  • Patent number: 11514078
    Abstract: In some embodiments, a system for synchronizing content with client devices receives a request from a client device to synchronize operations pertaining to content items associated with a user account registered at the system. The request can include the operations and a cursor identifying a current position of the client in a journal of revisions on the system. Based on the operations, the system generates linearized operations associated with the content items. The linearized operations can include a respective operation derived for each of the content items from one or more of the operations. The system converts each respective operation in the linearized operations to a respective revision for the journal of revisions and, based on the cursor, determines whether the respective revision conflicts with revisions in the journal. When the respective revision does not conflict with revisions in the journal, the system adds the respective revision to the journal.

  • Patent number: 11516288
    Abstract: The disclosed technology addresses the need in the art for synchronizing a content library between a content management system and client devices. Each content item in a user's content library is stored on the content management system and a record of each change to the content library is recorded in a content journal. A client device transmits a synchronization request that a portion of the content journal representing unsynchronized changes be processed to update the content library on the client device. The synchronization request includes a content library identifier and a content journal number identifying the content entry in the content journal last processed by the client device. Synchronization commands are sent based on the content entries not processed by the client device. Updated synchronization data representing the processed content entries is sent to the client device after synchronization is completed.
