1. Field of the Invention
The present invention relates to a flash memory encryption device that enables various types of memory cards can be encrypted or decrypted so as to achieve the goal of protecting the data of the memory card.
2. Description of Related Art
Accompanying the science and technology developing, the memory card manufacturers had already produced many various type memory cards, such as SmartMedia, CompactFlash, MMC, Security Digital (SD), Memory Stick, Memory Stick Pro, xD or Microdrive, Memory Stick Duo and Memory Stick Pro Duo memory card etc., and many card reader were designed to read the data of the various data.
There were many multi-in-one flash memory card readers had been produced in the markets for reading various memory cards, such as SmartMedia, CompactFlash, MMC, Security Digital (SD), Memory Stick, Memory Stick Pro, xD or Microdrive, Memory Stick Duo and Memory Stick Pro Duo memory card etc.. However, the prior art flash memory card readers did not have ability of protecting the data of the memory cards being misread by other users, so the memory card owner must keep his/her memory card very carefully, so as to prevent his/her memory card from losing, due to the data of the memory cards can be read from any flash memory card reader, therefore, the prior art flash memory card readers could not meet the requirement of data security.
There is therefore a need for a new and improved strategy and technique for overcoming these deficiencies and the present invention overcomes these deficiencies in a new and novel fashion.
The present invention generally relates to a strategy and a technique, which overcomes some or all of the above referenced deficiencies associated with prior memory card reader.

Referring to
For controlling the controller 40 to execute data encryption/decryption function, the flash memory encryption device of the present invention further comprises a lock seat 45 protruded from the third opening 16 and coupled to the controller 40 through wires 46; whereby a key 47 can be inserted into the lock seat 45 for controlling the controller 40 whether to execute encryption/decryption data function or not. The controller 40 executes data encryption/decryption function when the key 47 is inserted into the lock seat 45 and turned to an on position, and the controller 40 does not execute the data encryption/decryption function when the lock seat 45 is turned off, so the flash memory encryption device of the present invention could execute data encryption/decryption function to the memory card 60 according the status of the lock seat 45.
Furthermore, the flash memory encryption device of the present invention further comprises an indicator, for example but not limited to a LED, disposed on the front edge of the printed circuit board 20 and protruded from the hole 17 for indicating the access status of the flash memory encryption device.
While operating, the user can connect a cable 70 between the second connector 50 of the flash encryption device of the present device to a host computer (figure not shown), and insert a memory card 60, for example but not limited to a CompactFlash memory card into the first connector 30, then inserts the key 47 into the lock seat 45 and switches the key 47 to the on position, then the data wrote to/read from the memory card 60 will be encrypted/decrypted and the memory card 60 can not be read without using the key 47 of the flash encryption device of the present device so as to achieve the goal of protecting the data of the memory card 60.
