An anti-attack palmprint authentication method and its application authentication system

Abstract

The invention provides an anti-attack palm print authentication method and an authentication system with the anti-attack palm print authentication method applied. When palm print images are collected through a shooting unit, a first standard palm print image and a second standard palm print image are collected under the conditions that a flash lamp is turned on and the flash lamp is turned off; the shooting unit carries out collection many times to obtain multiple palm print images to be authenticated, wherein the flash lamp is turned on or turned off randomly in each collection process of the palm print images to be authenticated, first palm print images to be authenticated are collected when the flash lamp is turned on, and second palm print images to be authenticated are collected when the flash lamp is turned off; the first palm print images to be authenticated collected when the flash lamp is turned on are compared with the first standard palm print image through the palm print authentication system, the second palm print images to be authenticated collected when the flash lamp is turned off are compared with the second standard palm print image through the palm print authentication system, authentication is passed when comparisons are identical, and attacks of high-definition pictures can be effectively avoided by means of random flashing and corresponding authentication.

Description

Technical field [0001] The invention relates to the technical field of palmprint recognition, in particular to an anti-attack palmprint authentication method and an authentication system for its application. Background technique [0002] Palmprint recognition is an emerging identity recognition technology, which has the advantages of easy collection and rich texture. [0003] However, the existing palmprint recognition technology has major shortcomings and cannot effectively counterfeit attacks such as the use of high-definition palmprint photos. If illegal users use high-definition palmprint photos to attack, they will pass system verification; and if in order to prevent photo attacks, Improvements in hardware will inevitably require the addition of other auxiliary equipment, which will increase system overhead, reduce the versatility of palmprint recognition, and increase costs. Summary of the invention [0004] In view of the above-mentioned shortcomings of the prior art, the pu...

Problems solved by technology

[0003] However, the existing palmprint recognition technology has major flaws and cannot effectively counteract counterfeiting attacks such as using high-definition palmprint photos. If an illegal user uses high-definition palmprint photos to attack, it will pass the system verification; To improve the hardware, it is necessary to add other auxiliary equipment, which will increase the system overhead, reduce the versatility of palmprint recognition, and increase the cost.
