A method and system of enforcing file authorization access. The method may include generating an authorization combination at a metadata server and encrypting the authorization combination. The authorization combination may include a block combination including a block list for accessing user requested data from a storage server system and an authorization prefix. The authorization prefix may indicate at least one operation which the user requesting data access is authorized to perform. The method may further include receiving the encrypted authorization combination at the storage server, and decrypting the encrypted authorization combination to recover the block list for retrieving the user requested data.
