Abstract

An access control program is executed by a specific electronic device first connected to the non-volatile storage device to associate with the specific electronic device to be given full access to the storage, executed by the specific electronic device to set the specific electronic device associated with the non-volatile storage device to a first mode permitting full access to the storage, executed by an arbitrary electronic device connected to the non-volatile storage device to judge whether the arbitrary electronic device is the specific electronic device associated with the non-volatile storage device by performing certification; and executed by the arbitrary electronic device connected to the non-volatile storage device to perform mode setting.

Dependent claims

A non-volatile storage device removably connected to an electronic device, comprising a storage capable of reading and writing data configured to store an access control program, the program being readable by the electronic device,

wherein the program comprises:
being executed by a specific electronic device first connected to the non-volatile storage device to associate with the specific electronic device to be given full access to the storage;
being executed by the specific electronic device to set the specific electronic device associated with the non-volatile storage device to a first mode permitting full access to the storage;
being executed by an arbitrary electronic device connected to the non-volatile storage device to judge whether the arbitrary electronic device is the specific electronic device associated with the non-volatile storage device by performing certification;
and
being executed by the arbitrary electronic device connected to the non-volatile storage device to perform mode setting so that the arbitrary electronic device connected to the non-volatile storage device is set to the first mode when the arbitrary electronic device is judged to be the specific electronic device based on the certification, or so that the arbitrary electronic device connected to the non-volatile storage device is set to a second mode restricting access to the storage when the arbitrary electronic device is not judged to be the specific electronic device based on the certification,
every time the non-volatile storage device is connected to a new electronic device, the new electronic device being set to the first or second mode based on a result of the certification.
