A data capsule comprises an encrypted data hold means which holds an encrypted version of data which is provided for use, a verification means which communicates with an external proving device to get proof data generated by it and verifies the legitimacy of the proof data, a usage control means which enables the use of the data based on the verification result provided by the verification means, and a decryption means which decrypts the data held by the data hold means. The data is decrypted for use in response to the successful verification of the proof data from the proving device.
