A biometrics-based safe printing method and system

Abstract

The invention discloses a biometrics-based safe printing method and system, The method realizes identity authentication by using human body biometrics, and encrypts and protects print data at the sametime. The method comprises the following steps: when a user submits a print request, a print client obtains encrypted authentication data and combines the extracted user biometrics vector for identity authentication, generates a master key, and then combines the generated symmetric encryption key with a random number to encrypt the print file; When the user starts the print job, the print serveradopts a similar identity authentication method to authenticate, obtains the master key and generates a decryption key combined with the random number in the print request data, decrypts the print file and drives the printer to start printing. Compared with the prior art, the invention realizes the security protection of the biometrics and the key generation and negotiation by introducing the biometrics converter technology, and enhances the security of the prior biometrics-based printing method.

Description

technical field [0001] The invention belongs to the field of printers, and in particular relates to a safe printing method and system utilizing biometric identification and biometric converter technology. Background technique [0002] At present, the measures to enhance the security of the printing system mainly include means such as identity authentication and printing data encryption. Among them, the commonly used identity authentication methods in the printing system include passwords, employee smart cards, biometric authentication, etc.; passwords are easy to forget, weak passwords are cracked by violence, etc., and employee smart cards cannot really verify user identities, because anyone can use them. User's lost employee card. Identity authentication based on human biometrics can avoid the above problems. Therefore, more and more security systems have begun to use human biometrics to build authentication modules. In addition, encryption is a common means to protect t...

Problems solved by technology

This method uses asymmetric cryptography to complete the authentication and key negotiation process, and uses DES symmetric cryptography to encrypt data; this method has the risk of key leakage. If the user's private key is leaked, the security of the printing task cannot be guaranteed.
