A proposed technique of online face authentication to be used for the user identification

摘要

A technique of online face authentication has been proposed which may be used for the user identification. Pre processing of acquired image has been accomplished through consecutive steps viz. image reading and subsequent adjustment of illumination level and feature extraction from a certain portion of the clipped image to form a template. Provision for automatic uploading of the template through internet to remote server by the client background service has been made. Eigen values of the clipped block of image, i.e. template have been calculated and compared with those of already saved image in the remote server in order to authenticate the received image along with the password of the user. The present work based on person based authentication is expected to be less prone to be cracked by the hackers and has provided a higher recognition rate of the transmitted images from the client side.
