Abstract

The embodiment of the invention discloses a living body detection method and system for a target object, and the method comprises the steps: carrying out the imaging of a to-be-detected target object,and generating an image of at least one mode; based on an attack type identification model, identifying the image of at least one mode, and determining a pre-judged attack type of the to-be-detectedtarget object corresponding to the image of at least one mode, wherein the pre-judged attack type is an element in an attack type set; determining a living body detection model associated with the pre-judged attack type; inputting the image of at least one mode of the to-be-detected target object into the associated living body detection model for detection, and determining whether the to-be-detected target object is a living body or not.

Description

technical field [0001] The embodiments of this specification relate to the technical field of data processing, and in particular to a method and system for detecting a living body of a target object. Background technique [0002] With the wide application of identity recognition technology in various fields, such as using face recognition, palmprint recognition or fingerprint recognition to realize access control unlocking, mobile phone unlocking and online payment, etc., the security of identity recognition technology has become more and more popular. s concern. [0003] At present, there are many lawbreakers who forge living bodies for identification, and conduct acts that endanger property, personal, and public safety after successful identification. Among them, living bodies refer to living objects, such as living animals, plants, human bodies and its organization. However, detection of a living body and prevention require high costs. [0004] Therefore, in order to r...
