Production method and equipment of fake iris template and identity authentication method and equipment

Abstract

The invention provides a production method and equipment of a fake iris template and an identity authentication method and equipment. The production method of the fake iris template comprises the following steps: (A) collecting the iris image of a user, and preprocessing the collected iris image to obtain an iris comparison area; (B) selecting the images of a preset number of subareas from the iris comparison area; (C) utilizing a non-invertible algorithm to independently encrypt the images of the preset number of subareas; (D) replacing the images of the preset number of subareas in the iris comparison area with the encrypted image to generate a fake iris image; and (E) extracting fake iris feature codes from the fake iris image to generate the fake iris template. The above fake iris template does not reflect the truly complete iris, can effectively protect individual privacy and improves iris identification safety.

Description

technical field [0001] The present invention generally relates to iris recognition technology, and more specifically relates to a method and device for generating a pseudo iris template, and an identity authentication method and device based on the pseudo iris template. Background technique [0002] With the development of social economy and science and technology, biometric identification technology has increasingly entered people's lives, and has applications in airport security checks, office attendance, home access control, banking services, etc., and has broad application prospects. And huge economic benefits, become an important technical direction. The iris recognition technology in the biometrics recognition technology uses the iris characteristics of people as the identification basis, which has the advantages of high accuracy and great application potential. It has been successfully applied in coal, banks, prisons and other places. [0003] With the development of...

AI Technical Summary

Problems solved by technology

[0004] Iris recognition technology is deeply applied to various places in life, which brings many conveniences but also brings hidden dangers: all places collect people's iris characteristics and bind them with personal identity information, and the system security performance of these places is average. Not high, the iris features are easy to be stolen or copied, resulting in personal privacy leaks, what is more serious is that criminals may use the stolen iris features to forge irises, and then pretend to be real irises to deceive important places (such as home access control, safes, etc.) , bank teller machines, border security) iris recognition system recognition, in order to achieve illegal purposes
