Method for logining BIOS based on fingerprint verification

Abstract

A BIOS logging method based on fingerprint certification includes inserting fingerprint module observing module format of BIOS into BIOS, starting computer up to finalize self-detection, calling up fingerprint module by BIOS to scan user fingerprint for collecting fingerprint image, comparing collected fingerprint image with fingerprint of fingerprint information bank and starting up operation system after BIOS is operated normally by system if certification is passed or otherwise switching system off by protection.

Description

technical field [0001] The invention relates to the technical field of computer security, in particular to a bios login method based on fingerprint authentication. Background technique [0002] With the popularity of computers and the improvement of the Internet, security is the first consideration for many computers and their systems. In many current computer systems, including many very confidential systems, the traditional identity authentication method is used for user identity authentication and access control, that is, the method of "user ID+password". In fact, this scheme has some hidden problems, often resulting in a situation where the code is recognized but the person is not recognized. Once the password is forgotten, stolen or cracked, it will cause trouble or even heavy losses to the user. The usual workaround is as follows: [0003] 1) The system prevents password theft by requiring users to change their passwords in time. The disadvantage of this method is th...

Problems solved by technology

[0003] 1) The system prevents password theft by requiring users to change their passwords in time. The disadvantage of this method is that it increases the user's memory burden and cannot fundamentally solve the problem

The defect of this method is: this protection is based on the operating system, if an illegal user starts the system with other operating systems, the system will still not be protected

[0006] To sum up, although there are many methods of system identity authentication and access control, some of them are only protection methods at the operating system level, and some use frequent password changes to protect the system. , the above methods are useless.
