Abstract:
1. An IC card, comprising: a holder configured to store first digital contents; a certificate data storage configured to store certificate data including key information associated with the first digital contents; an encryption processor; and an execution processor, the execution processor being configured to execute a predetermined command when receiving a predetermined trigger signal, wherein the predetermined command executed by the execution processor causes the execution processor to create the first digital contents when a create right of the first digital contents is acknowledged; store a state of the IC card before transmission of the first digital contents; causes the encryption processor to perform an encryption process on the first digital contents, based on the key information associated with the first digital contents; deletes the first digital contents from the holder when a commit instruction indicating completion of a reception process on the encrypted first digital contents is received from a destination device; and performs a return process to the state of the IC card stored in the execution processor when a transmission process on the first digital contents is interrupted.
