Method for performing identity authentication and file encryption and decryption based on fingerprint UsbKey

Abstract

The invention discloses a method for performing identity authentication and file encryption and decryption based on a fingerprint UsbKey, relating to the field of computer information security. A memory unit, a fingerprint identifier and an indication light are integrated on U disc-like equipment with USB interfaces, configuration management is performed by special PC (personal computer for running Windows, Linux and other normal operation systems) terminal management software, and the U disc-like equipment has a memory function of an ordinary U disc, enables a user to perform identity authentication and file encryption and decryption through fingerprints and also can be taken as the ordinary U disc. Password and key management are performed by the safe and convenient method, and loss caused by the fact that a password or a key is lost is avoided.

Description

[0001] technical field [0002] The invention relates to a method for realizing identity authentication and file encryption and decryption based on fingerprint UsbKey, which belongs to the field of computer information security. By integrating a storage unit, a fingerprint reader, and an indicator light on a U disk-like device with a USB interface, the method is controlled by a special PC. (Personal computers running Windows, Linux and other common operating systems) UsbKey management software to configure and manage, with the storage function of ordinary U disks, so that users can quickly and conveniently perform identity authentication and file encryption and decryption through fingerprints. Background technique [0003] In recent years, with the popularity of personal computers and office automation, protecting sensitive files from leakage has become a hot issue that people pay attention to. In addition to directly stealing physical storage devices, intruders can also s...

Problems solved by technology

General users are reluctant to use these applications because they are cumbersome to operate, not tightly integrated with the overall system, and vulnerable to attacks.

[0004]Current network identity authentication methods are divided into single-factor authentication / two-factor authentication / multi-factor authentication. The more factors, the higher the security. The most widely used single-factor authentication is password , it has security risks such as small difficulty in cracking, hard to remember, and the same password for multiple accounts; two-factor authentication methods include USB-KEY / IC card / dynamic password card, etc. The most typical method of multi-factor authentication is certificate + usbkey, they There are potential safety hazards such as easy loss, difficult accountability, and easy password cracking; the fingerprint UsbKey+ certificate just solves the above problems, so the fingerprint UsbKey+ certificate is the most secure and convenient way in multi-factor authentication
