摘要
An external storage device connectable to an information processing apparatus is provided. The storage device includes: an input/output interface via which data is exchanged with an information processing apparatus; a first storage region where data associated with first and second validity periods is stored; and a second storage region where a control program is stored. While the first validity period is used when the external storage device is connected to one information processing apparatus, the second validity period is used when the external storage device is connected to another information processing apparatus. The control program causes a processor to execute the steps of: establishing connection of the external storage device to an information processing apparatus; identifying any one of the validity periods as a validity period to be used for the data; and executing predetermined security protection processing on the data in accordance with the identified validity period.
