Problems solved by technology

Furthermore, even for complex systems that account for eye blinks and other types of facial motion, detecting a live face can be frustrated by using a video stream of someone else's face instead of a live face

Embodiment approach

[0104] Other implementations of the face verification system 1 are possible. Figure 8A A method 90 is shown in . Such as Figure 8A As shown in , method 90 begins in block 91 to capture a NIR image and a visible image. As described above, once the NIR and visible images are captured, method 90 moves to block 92 where human faces are detected in the NIR and visible images. Method 90 then moves to block 93 to verify the detected geometry for the face using any suitable method. After verifying the facial geometry, method 90 proceeds to block 94 where the detected face is biometrically verified. While image data of live and non-live skin has been used in various disclosed implementations herein, it should be appreciated that various other methods for verifying that a face is live can be performed. For example, iris recognition or retinal scanning may be used in some implementations. In other implementations, the subject's veins and arteries beneath the skin can be imaged to ...

Abstract

Systems and methods for detecting a live human face in an image are disclosed. The methods and systems are capable of receiving multispectral image data that includes a human face. The multispectral image data can comprise visible light image data and near-infrared (NIR) image data. The multispectral image data can be processed to detect the human face. The detected human face in the visible light image data can be associated with the detected human face in the NIR image data to determine whether the detected human face is a live human face.

Description

technical field [0001] The present invention relates to systems and methods for facial authentication. In particular, the present invention relates to systems and methods for detecting a human face and determining whether the detected human face is a live human face. Background technique [0002] Facial detection and / or verification systems may be useful in a variety of contexts, including, for example, parental control applications, law enforcement, mobile banking, and security applications. Conventional automatic face detection systems detect human faces in images. However, such systems generally cannot determine whether a face detected in an image was captured from a live human face, or merely from a photograph or other rendition of a human face. [0003] For example, in some cases, the detected face may come from an artificial source, such as a face in a photograph, an image of a face on a display screen, a mask, a model reproduction of a face, a mannequin, or any othe...
