Live face recognition method and device

Abstract

The present invention relates to the technical field of identity verification, in particular, to a living face recognition method, device and system. Including: obtaining a plurality of face images in real time; according to the face images, obtaining the fixation point or the movement track of the fixation point of at least one eye in each face image; according to the fixation point or the movement track of the fixation point of the eyes , judging whether the eyes move according to the prompt; if the judging result is yes, passing the biometric verification. In this method, when the user performs facial feature verification, the eyes must move according to the prompts, because the extraction of facial features and eye movement data are extracted from the same photo / same group of photos or videos, and illegal logins cannot use it. The face image or video can be used to "deceive" the verification device, so that this method can judge that the user matches the facial features, and the facial information comes from a living person in reality.

Description

technical field [0001] The present invention relates to the technical field of identity verification, in particular to a living face recognition method and device. Background technique [0002] Currently, facial recognition technology is widely used for identity verification in secure login systems. The current facial recognition technology generally obtains the current user's facial photo in real time through image acquisition equipment, and compares the facial photo obtained in real time with the previously stored facial photo based on the characteristics and distribution of facial features. If the comparison is consistent, the identity verification pass. [0003] However, in the process of facial recognition, illegal registrants can "deceive" cameras or other image acquisition devices by forging faces, so that the photos acquired by the image acquisition devices are not photos of living faces. For example, if the registrant's face photo or face video clip is placed in f...

[0003] However, in the process of facial recognition, illegal registrants can "deceive" cameras or other image acquisition devices by forging faces, so that the photos acquired by the image acquisition devices are not photos of live faces

For example, if the registrant's face photo or face video clip is placed in front of the image acquisition device, the current user's face photo acquired by the image acquisition device is actually from the photo or video clip, or illegal registrants can also forge a 3D human face. Face model, the 3D face model is placed in front of the image acquisition device. At this time, the face photo acquired by the image acquisition device is a photo of the 3D face model, but when comparing the characteristics and distribution based on facial features, it is Unable to detect this point, this has caused the problem of weak anti-counterfeiting ability and low security of the identification system
