摘要:
To provide a mechanism for preventing information leakage by erasing stored information if a preset condition is not satisfied, because if an external storage device in which the information is stored is stolen or lost the risk of information leakage through decryption still remains even in the case where the information is encrypted. An external storage device has a locking management function capable of setting available conditions for stored information and controlling permission/prohibition of user access depending on whether the conditions are satisfied. User access is permitted if the available conditions are satisfied. The stored information is erased if the available conditions are not satisfied.

In a client/server architecture system, a device management system having the function of safely sharing a device without compromising user convenience is provided.The device is coupled to a terminal that the user uses or a hub coupled to a network. A device management manager having a device driver function and communication function installed on the terminal or the like, a virtual device manager having a device driver function and communication function installed on the server, and an authentication server that manages access permission for the device allow the device to be virtually available as in the case of the device directly coupled to the server while managing the access to the device.

A thin client terminal that can perform information processing in an off-line state is provided. A thin client terminal 101a sends a request for registration of data to be used off-line and designation of application software to be used off-line to a management server 107 through a remote computer 104. The management server 107 registers the data and application software according to the request. The thin client terminal 101 requests the management server 107 to acquire the requested data and application software, receives the data and application software, and stores the received data and application software into a storage medium 110.

摘要:
A memory device is provided which is connected to operate with power and clocks supplied from a host apparatus. The memory device includes external terminals, a flash memory chip to store data, an IC chip to process data; and a controller chip connected with the external terminals, the flash memory chip and the IC chip, wherein, the flash memory chip, the IC chip and the controller chip are discrete chips. The controller chip writes data inputted from the host apparatus into the flash memory chip or the IC chip and transfers data read from the flash memory chip or the IC chip to the host apparatus, based upon commands from the host apparatus.
