PROBLEM TO BE SOLVED: To provide a device and a system for authentication and a storage medium which can prevent data from illegally being copied to plural terminals by performing authentication processing using individual data of storage media when terminals are connected and identification data issued at the time of data transfer. SOLUTION: In the authentication system 1 wherein a PC 2 and a WAP 3 are connected, the PC 2 issues a data ID at the time of data transfer and the PC 2 and WAP 3 share a memory card ID characteristic of a memory card of the WAP 3 and the issued data ID. When a connection is made again, the PC 2 obtains the memory card ID and data ID from the WAP 3 and compares them with a registered memory card ID and a registered data ID to perform authentication. According to the authentication result, a transfer function for data is limited. |
