OFFLINE SIGNATURE VERIFICATION

Abstract

Biometrics has provided various techniques to recognize a person based on physical attributes. Biometric technologies are becoming foundation for highly secure identification solutions.The need for biometrics can be found in many local and government departments, military operations etc.Features measured can be any or combination of face, retina, handwriting, iris, signature and tone of voice. Signatures are extensively used for the purpose of providing authenticity for a person.In various commercial applications like transactions,bank cheques; it is unrealistic to check manually all the person’s signature in limited amount of time.So there is highly need for automated signature verification and identification techniques.Handwritten signature are different from other textuals, people used to draw a shape as their signature which is in static form.So we can infer lot of important information from these shapes and can use them for identification and verification purpose. Signature can be done in two modes, when a signature is made on paper with a pen it is called an offline mode.If one does a sign on a tablet in real time it is called an online mode.In online mode of signatures some more information which is dynamic in nature can be inferred which is not possible to obtain in offline mode.Such dynamic information is pressure, time taken to put sign,pen angle etc. The present research work is done in the field of offline signature verification system by extracting some special features that make a signature difficult to forge. In this research work, existing signature verification systems have been thoroughly studied and a model is designed to develop an offline signature verification system.
