Problems solved by technology

However, there is no data encryption measure for data transmission between the central processing unit and the main storage unit storing data and fingerprint templates
Once the fingerprint template is intercepted, the simulated sending of the fake fingerprint template to the central processing unit may cause false recognition of the fake finger

Abstract

The invention provides a modular fingerprint U disk and a communication method thereof. The modular fingerprint U disk comprises a fingerprint U disk main control unit, a fingerprint identification module, a Flash memory and USB interfaces, wherein the fingerprint U disk main control unit is used for controlling the fingerprint identification module and the Flash memory and is responsible for communication with an external device; the fingerprint identification module is composed of a fingerprint algorithm chip and a fingerprint sensor for fingerprint registration and fingerprint matching; and the Flash memory is connected with the fingerprint U disk main control unit for storing encrypted U disk chip data. According to the modular fingerprint U disk and the communication method thereof provided by the invention, hardware protection for the data is realized and fingerprint template data can be stored more safely; internal data in the U disk are transmitted in an encrypted mode, and the data can be transmitted more safely; and due to the dual-interface USB, functionality and convenience of the fingerprint U disk use are improved.

Description

technical field [0001] The invention relates to the fields of mobile storage and security authentication, in particular to a modularized fingerprint U disk and a communication method thereof. Background technique [0002] U disk, the full name of USB flash drive, has the advantages of small and portable, large storage capacity, cheap price, reliable performance, etc. It is used in various fields such as personal, business, and military. But with the development of information technology, people have higher and higher requirements for information security. U disk, as a portable mobile storage device, is prone to loss or theft, so U disk data protection is particularly important. [0003] Fingerprint U disk is also called fingerprint encrypted flash disk, which combines U disk technology with fingerprint recognition technology. Fingerprint is a unique feature of the human body. As one of the most widely used and cheapest identification technologies in biometrics, fingerprint...
