Biometric Control System of Face Recognition Access and Live Face Detection

Biometric access control system can not remain advantageous if it is not reliable. Hackers can easily enter the premises by spoofing the face recognition access control system. Unauthorized access can cause problems on site. A good quality face recognition access control system can make the difference between a live face and a photograph. Live face detection can be done by a biometric access control in a number of ways. Some of the common algorithms, which a biometric access control utilize to recognize live faces of good quality can be given as below:

The compounds and the standard deviation in the input image: face recognition access control system can be designed to differentiate a real face and a photograph, by analyzing the number of components and the gap in the input image. An image is small and flat, the number of high frequency components in the photograph may be lower.

* Observing the eye movements: Eye movements are determinants to live face detection. There are slight variations in facial features and images of the face shape of sequential faces. A smart biometric access control can notice eye movements in the sequential face images and conclude whether the given face is a real human face or a simple photograph.

* Method based on face detection feature live: The proposed method increases the live face detection accuracy rate in biometric. The input image must have a resolution. The face is large and sensitive skin tone. Facial recognition access control system by the method based on the features for live face detection are not able to match an image with the image in the database.

* Movements of the face for live face detection: This system can be based on the detection of head movements and facial gestures. It considers eye movements, eyebrow movements, mouth and lip movements, head movements and other factors. The input image which is not, is a live face and not a picture! The biometric access control system does not need an expensive camera. It can operate in a low cost camera and guarantees higher security by denying easy entry.
