Abstract

The invention relates to a data access device, system and method, which are suitable for a source device and a data access device. The data access device stores an access application program, after being connected with the data access device, the source device generates an external operation command according to the application program and transmits the external operation command to the serial-connection type access module of the data access device, and the data access device analyzes an external operation instruction according to an access application program and carries out access actions in the serial-connection type access module, or in a concealed storage module through the serial-connection type access module. Accordingly, the safety in the use of the data access device by a user is reinforced, and when the user has important data, the protection to data privacy can be reinforced.

Description

Technical field [0001] The invention relates to a data access device, a system and a method thereof, and more particularly to a data access device with a hidden storage module that cannot be read by the outside world. Background technique [0002] At present, due to the rapid development of science and technology, since pocket disks with universal serial connector (USB) interfaces came out, they have gotten rid of floppy disks because of their large data storage capacity, fast data transmission, and convenient portability. Due to the limited capacity of floppy disks and the time-consuming problem of burning optical discs, it has become an extremely convenient mobile storage device. However, important data in general portable hard disks can be easily stolen, tampered with, or destroyed, which highlights the increasing importance of various electronic access devices to their confidentiality. [0003] The current methods for data encryption include fingerprint encryption, chip encryp...
