Abstract:
A data transmission apparatus, a data reception apparatus, and a data transfer system prevent a case where same usable data is present in plural apparatuses at the same time and can certainly move data, in MOVE processing of the data between the data transmission apparatus and the data reception apparatus. The data transmission apparatus includes a synchronous control unit synchronizing a timing of (i) deleting or invalidating, in the data transmission apparatus, move-target data and (ii) decrypting, in the data reception apparatus, the move-target data that has been encrypted. With this, it becomes possible to prevent a case where the same usable data is present in plural apparatuses at the same time.
