Patent number: 11954221Abstract: A request is received from a user at a client to access a file of a set of files backed up to a backup server. Upon verifying a password provided by the user, the client is issued another request for authentication. A first data structure is received responsive to the request. The first data structure is generated using identifiers corresponding to a set of files at the client of which at least some presumably have been backed up to the server. A second data structure is generated. The second data structure is generated using identifiers corresponding to the set of files backed up to the server. The first and second data structures are compared to assess a degree of similarity between the files at the client and the files backed up to the backup server. The user is denied access when the degree of similarity is below a threshold.Type: GrantFiled: February 24, 2023Date of Patent: April 9, 2024Assignee: EMC IP Holding Company LLCInventors: Yossef Saad, Itay Glick

Patent number: 11956240Abstract: One example method includes providing temporary access to a computing system and to providing temporary access as a service. The features of a temporary access can be defined by an entity and a user may be able to obtain a token that includes these features, which may be embedded in the token as claims. The user's access is then controlled in accordance with the embedded claims. The temporary access as a service can be federated. The token may include trust levels and tolerance limits. Further, aspects of the temporary access can be monitored and/or changed. Adjustments to trust levels can be automated or manually performed. Further trust for specific users can be gained or lost over time based on at least previous accesses.Type: GrantFiled: April 19, 2021Date of Patent: April 9, 2024Assignee: EMC IP HOLDING COMPANY LLCInventors: Hana Schuster Smith, Janardan Revuru

Patent number: 11947499Abstract: A peer-to-peer global namespace for storage system metadata federations. Specifically, the disclosure proposes a peer-to-peer metadata federation architecture, where enterprise storage metadata for any and all geo-distributed sites may be distributed across and continually reconciled by a network of nodes, instead of being maintained by a single node assigned to a given geographic location. In implementing a federation, the network of nodes may lack exploitable, centralized points of vulnerability, and therefore, may exhibit no central point of failure. Furthermore, the disclosure proposes the implementation of a global metadata namespace for the enterprise storage metadata spanning the entirety of an enterprise (across all geographic locations). The global metadata namespace may be maintained on each node through event-based synchronization.Type: GrantFiled: July 31, 2020Date of Patent: April 2, 2024Assignee: EMC IP Holding Company LLCInventor: Qi Bao
