  • Access control based on operation expiry data
    Patent number: 10223363
    Abstract: The controlling of access to a file system entity based on location of the requestor and operation expiry data of the file system entity. Operation expiry data and location data are associated with a file system entity (e.g., a file, a directory, a partition, or a disk) such that the file system entity and the operation expiry data and the location data are moved or copied atomically together. Upon receiving a request to perform an operation on the file system entity, the system identifies a location status of the requestor. The system then identifies expiry data that corresponds to the location status, and that is associated with the requested operation. The system then uses the identified expiry data to determine whether or not the requested file operation is to be permitted.
