Biometric authentication technique using smartphone sensor

Abstract

User identity theft is a growing challenge for security of electronic systems. Traditional authentication techniques such as password and PIN code are more vulnerable to this problem. On the other hand, biometric authentication techniques are safer as compared to password identification for authentication purpose. Biometric techniques use certain characteristics of human to authenticate the legitimate user. This paper presents a biometric authentication mechanism using motion sensor of smart phone. The user has to perform signature by moving his phone, the motion pattern is detected using accelerometer of the smartphone. We have used the concepts of signal matching for identification mechanism. Results depict that legitimate user can be identified using a certain level of error threshold.
