Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a living body recognition method and system based on iris changes. According to the light-sensitivity characteristics of the iris, the state of pupil constriction within a period of time is obtained, and by judging the state of pupil constriction and the change in illumination within this period of time, In order to solve the problem that the existing technology cannot quickly and efficiently carry out living body recognition, and the accuracy of living body recognition is low

Abstract

The invention provides an iris-change-based living body identification method and system. The method comprises: screen brightness information of a current device is obtained; pupil constriction state information of a user for the current device screen brightness is obtained; the screen brightness information and the pupil constriction state information are compared to obtain association coefficients of the screen brightness information and the pupil constriction state information; and the association coefficients are compared with a preset threshold value and if the association coefficients are larger than the threshold value, the user is determined to be the human being. With the method, intelligence of face detection equipment is enhanced; accuracy of living body identification by the face detection equipment is improved; and an objective of manpower loss reduction is achieved. Moreover, the method and system are simple and are easy to implement and popularize.

Description

technical field [0001] The invention relates to the field of biological feature identification, in particular to a living body identification method and system based on iris changes. Background technique [0002] Face detection technology is based on human facial features, and compares the input face image or video stream with known faces to identify the identity of each face. Face recognition technology has a wide range of application prospects , can be used in government, military, banking, social welfare, e-commerce, security defense and other fields, such as: face recognition access control, on the one hand, it can be used as the attendance of in-service personnel, on the other hand, it can also identify sensitive people according to the built-in database of the system The bank can use the face recognition system as an auxiliary voucher for withdrawals to prevent fraudulent claims and financial fraud; the public security organs can use the face recognition system to hunt...
