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

Embodiment Construction
[0050] Exemplary embodiments of the present invention will now be described in detail, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like parts throughout.
[0051] figure 1 A flowchart showing a method for generating an irreversible pseudo-iris template (hereinafter referred to as a method for generating a pseudo-iris template) according to an exemplary embodiment of the present invention.
[0052] refer to figure 1 , in step S10, collect the user's iris image, and perform preprocessing on the collected iris image, so as to obtain the iris comparison area.
[0053] Specifically, in step S10, multiple iris images of the user can be collected, and an iris image that meets the recognition requirements is selected from the multiple iris images as an iris image for subsequent processing, and then the selected iris image is pre-processed. Process to get the iris comparison area. For example, a quality assessment may be p...

A method and device for generating a pseudo iris template and an identity authentication method and device are provided. The method for generating a pseudo iris template includes: (A) collecting an iris image of a user, and preprocessing the collected iris image to obtain an iris comparison area; (B) select images of a predetermined number of sub-regions from the iris comparison region; (C) utilize an irreversible algorithm to encrypt images of the predetermined number of sub-regions respectively; (D) compare all images in the iris comparison region The images of the predetermined number of sub-regions are replaced by encrypted images to generate a pseudo iris image; (E) extracting a pseudo iris feature code from the pseudo iris image to generate a pseudo iris template. The above pseudo iris template does not reflect the real and complete iris, which can effectively protect personal privacy and improve the security of iris recognition.
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...
