Embedded encrypted mobile storage device and operation method thereof

Abstract

The invention discloses an embedded encrypted mobile storage device and an operation method thereof. The embedded encrypted mobile storage device comprises a storage medium, an identity recognition device and a singlechip, wherein the storage medium and the identity recognition device are connected with the singlechip, an equipment encryption-decryption module is arranged in the singlechip, and the equipment encryption-decryption module is used for correspondingly setting unlocked stage of the embedded encrypted mobile storage device to be unlocked or locked according to the identity recognition information input by the identity recognition device; and the singlechip is used for carrying out treatment corresponding to an operational order on the storage medium according to the unlocked state when receiving an external reading-writing operational order. The embedded encrypted mobile storage device has the advantages that data encryption and decryption can be separately completed, plug and play is realized, size is small, and hardware cost is low.

Description

technical field [0001] The invention relates to the field of mobile storage, in particular to an embedded encrypted mobile storage device and an operating method thereof. Background technique [0002] The mobile storage device is a portable storage product that uses a hard disk as the storage medium to exchange large-capacity data between computers. The most common mobile storage device is a mobile hard disk, and its existence provides many conveniences for modern people's daily life and work. The current mobile storage devices generally use the universal serial bus to communicate with the external host for communication and transmission connection. Universal Serial Bus (USB, UniversalSerialBus) is an interface standard widely used in various electronic products at present, and its main advantage is that it supports plug-and-play and is easy to install and use. [0003] At present, more and more users have become accustomed to storing a large number of files in mobile stor...

Problems solved by technology

[0005] 1. In the invention patent application document with the application number 200910109577.5, the fingerprint encryption and decryption needs to cooperate with the computer, and the encryption and decryption operation is performed by installing the corresponding software on the computer. Every operation must be connected to the computer, which is inconvenient to operate and relies on Encryption and decryption by an external computer still poses certain security risks

[0006] 2. In the invention patent application document with the application number 201210179058.8, the problem of relying on computers for fingerprint management was solved, but the management of fingerprints and the encryption of data stored in the hard disk are based on external hardware products (fingerprint processor TFS5416 and security chip), which increases hardware complexity and cost, and also makes the mobile hard disk bulky and inconvenient to carry
