Lip biometrics: An enhanced method for key generation

Abstract

Authentication is the key factor of badging the right person for access which enhances the security system in wireless communication. In this paper, an efficient way of authenticating a person is achieved by selecting a novel biometric feature as ―Lip. Series of image processing procedures are done to enhance the image features and also to fix the boundary values for corresponding pixels. A new filer termed as ―Weighted Triangular Filter (WTF) is formulated to enhance the image features. Finally an 8 bit key is generated in lieu of biometric feature which is then used for encryption in wireless mode.
