Abstract

The invention discloses a method for two-factor identity authentication based on biometric technology: a user submits an account registration request to a server through a browser; generates a first random number through the server, and sends the first random number and the public key of the server to the browser; the user Set the user account and password on the browser; collect the user's biometric information, and send the user's biometric information to the browser; combine the password and biometric information set by the user through the browser to generate the user's master key; Use the server's public key to encrypt the first random number and the user's master key through the browser, and send the user account, the encrypted first random number, and the user's master key to the server; The account lookup is the first random number generated for the user account, and the server's private key is used to decrypt the encrypted first random number and the user's master key to obtain the decrypted user's master key and second random number.

Description

technical field [0001] The present invention relates to the technical field of encryption and decryption, and more specifically, to a two-factor identity authentication method and system based on biometric identification technology. Background technique [0002] With the development of Internet technology, there are more and more enterprise business applications based on WEB technology. Generally, WEB application systems use the method of "username + password" to realize account management and identity authentication, and there are many problems, including: simple passwords are easy to be cracked and leaked, complex passwords are easy to be forgotten, and passwords are not changed for a long time. Use the same user name and password to expand the scope of influence of password leaks, etc. With the increase in the number of application systems, the use of "username + password" user account management and identity authentication will significantly increase the workload of ent...
