US 2006/0218633 A1 · System and method for management of external storage medium

Abstract

An external storage medium management system takes into account the maintenance of data security in case an external storage medium has been taken out on emergency. It comprises an external storage medium device and an enclosure device, which is connected to a host side device and which accommodates the external storage medium device, the external storage medium device reports the result of authentication to the enclosure device in case authentication operation is done. On detection of extraction of the external storage medium device from the enclosure device, the external storage medium device of inhibits access to retained data and allows access to the data only in case the authentication in accordance with a preset system has met success. In case the enclosure device also has detected the extraction of the external storage medium device by a medium extraction detection unit, the enclosure device announces the status prevailing at the time of the extraction (authentication coincidence/non-coincidence/authentication data invalid/no authentication data) to the host side.

Dependent claims

An external storage medium device that may be accommodated in an enclosure device connected to a host side device, said external storage medium device comprising:

a data holding unit holding data;
a medium management unit verifying whether or not there persist right for access, based on input authentication information;
a medium extraction detection unit detecting that the external storage medium device has been extracted from said enclosure device;
and
an access control unit that exercises read/write control for said data holding unit responsive to a request from said host side device and inhibits data access, not mediated by said medium management unit, upon extraction from said enclosure device as an incentive.

2 more elements

A management method for an external storage medium device employing said external storage medium device and an enclosure device connected to a host side device and accommodating therein said external storage medium device, said method comprising:

a step of detecting extraction from said enclosure device of said external storage medium device, by a medium extraction detection unit which detects said extraction from said enclosure device;
and
a step of said external storage medium device, having detected extraction thereof from said enclosure device, subsequently inhibiting access to retained data until the time of success in authentication in accordance with a preset authentication system.
