Iris identification method and apparatus

Abstract

The embodiment of the invention discloses an iris identification method. The method comprises: iris feature information of a user is obtained; a vault value that is generated in advance is read, wherein the vault value is obtained in advance by calculation based on iris feature information of an authorized user and a preset encrypted secret key; according to the iris feature information of the user as well as the vault value, a decrypted secret key is calculated; whether the decrypted secret key obtained by calculation matches the preset encrypted secret key is determined; and if so, success of the iris identification is confirmed. In addition, the invention also discloses an iris identification apparatus. With the method and apparatus, encryption protection can be carried out on the terminal and leakage of iris feature information can be prevented effectively.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an iris recognition method and device. Background technique [0002] As the use scenarios and functions of electronic terminals become more and more extensive, more and more personal privacy information is stored in electronic terminals. Therefore, there are higher and higher requirements for the security and privacy of electronic terminals. Iris recognition It is a very popular identification method at present. However, due to the uniqueness and invariance of the iris, once the user's iris template is leaked, the security risk is irreversible, that is, the user cannot use a method similar to "replacing the password" to replace the iris. At the same time, electronic terminals are easy to be stolen due to their small size and portability. Therefore, when an iris recognition solution is applied to electronic terminals, how to ensure the security of stored iris templates is a c...

Problems solved by technology

However, due to the uniqueness and immutability of the iris, once the user's iris template is leaked, the security risk is irreversible, that is, the user cannot use a method similar to "replacing the password" to replace the iris

At the same time, electronic terminals are easy to be stolen due to their small size and portability, so how to ensure the security of the stored iris templates is a critical issue when applying iris recognition solutions on electronic terminals

At present, the main solution is to directly store the iris template in the terminal, or encrypt and save the iris template through a password set by the user. However, due to the reversibility of password encryption (that is, there is a decryption method that can restore the original data), there are still attackers who can After successfully decrypting the encrypted iris template, the possibility of leaking the iris template
