A Conceptual Study on User Identification and Verification Process using Face Recognition Technique

Abstract

The rapid growth of information and communication technology resulted in abundant data and information growth in every field with the necessity for high data security. Face recognition is one of the types of unique biometrics measure related to human characteristics,which can be used for identification or authentication purpose as individual’s claimed identity. Face recognition system acquired great scope for the past few years in image processing for the security purposes including identification and verification process, due to its applications in various domains like crime detection, banking, and defense. Based on face data acquisition, face recognition techniques can be broadly classified into three types asintensity images using local binarypattern, video sequences using training videos and 3D information using 3D feature extraction. This paper discusses different face recognition algorithms and analyses it uses its advantages and disadvantages. This paper also compares and discusses how these techniques can be used for various identification and verification system in various fields and attempts to disclose state of the art of face recognition technology
