Fingerprint ciphering flash memory disk

The utility model relates to a mobile memory, particularly a fingerprint encrypting flash memory disk and the fingerprint encrypting flash memory disk is encrypted through fingerprints and can effectively prevent the random access of other people. For achieving the purpose, the utility model realizes the way that the fingerprint encrypting flash memory disk comprises following structures that a memory is used for storing application programs, data which need to be protected, fingerprint data and basic information of a user; a fingerprint sensor grasps real-time fingerprint information according to the control of a controller and transmits the grasped fingerprint information to the controller, and the controller is used for controlling the data transmission among the memory, the fingerprint sensor and a terminal system. The utility model has the advantages and effects that the utility model has a good secrecy function for stored data, and information in the flash memory disk can not be read when a fingerprint is not the fingerprint of an owner. When the fingerprint encrypting flash memory disk is lost, the fingerprint encrypting flash memory disk can provide the basic information of the owner to a picker.
