Data storage security apparatus and method which erases memory and utilizes a power switch to cut-off electric power during unsuccessful access

摘要

When a connector of a data storage device 10 is connected to a connector 104 of a data processor 100, a power is supplied to a microprocessor 24, and the data storage device 10 sends a discrimination signal to the data processor 100. If the discrimination signal is decided to be a prescribed signal, the data processor 100 sends a detection signal to the data storage device 10. If the detection signal is not received or it is not decided to be a prescribed one, the microprocessor 24 makes a card mode controller 16 inactive to inhibit data read from a memory section 14, and it vanishes the data stored in the memory section 14.
