A Pixel Based Signature Authentication System

Abstract- Signature verification is the process used to recognize an individual’s h a n d-written s i g n a t u r e. The p r o c e s s o f verifying signature is cumbersome in practice. There is a need for automatic verification system for a signature since the signature has been a means of a person’s identification through ages. Verification of a signature can be done either Offline or Online based on the application. Online systems use dynamic information of a signature captured at the time the signature is made. Offline systems work on the scanned image of a signature. In this paper, we verify the off-line signatures by taking a boundary of the entire signature and do the pixel comparison. Signature is acquired using a scanner. Detection process is done after the data acquisition and pre-processing. Pre processing includes noise removal, grey-scale, manipulation, edge detection
