File Storage System And User Terminal
Abstract: A data storage system (1) uses an encryption format in which an encrypted file can be decrypted using a decryption key when decryption conditions set in the encrypted file are satisfied by user attributes set in the decryption key. The data storage system (1) stores an encrypted file encrypted using the encryption format in a file storage device (20). When user attributes are specified from a user terminal (10) the data storage system (1) extracts from among the encrypted files stored in the file storage device (20) those files for which the specified user attributes satisfy the decryption conditions and displays the extracted encrypted files classified by decryption condition.
