Zusammenfassung:A portable secure data file includes an encrypted data portion and a metadata portion. When a request associated with a current user of a device to access a portable secure data file is received, one or more records in the metadata portion are accessed to determine whether the current user is permitted to access the file data in the encrypted data portion. If a record indicates the user is permitted to access the file data, a content encryption key in that record is used to decrypt the encrypted data portion.
