I am facing some probs regarding offline signature verification..

need difference between offline and online and algorithm

There exists a range of biometric techniques, for example, signatures, fingerprints, Iris and so there is considerable interest in handwriting authentication signature verification system, as this is the cheapest way to human authentication. Fingerprints and iris scan requires costly equipment and Hencse may not be used in places such as day-to-day banking and so on forensic experts because I can not be used in every love There has been significant efforts towards the development of algorithms to validate and authenticate to the identity of the person. Many times the signatures is not readable even human beings. Therefore, the signature is treated as an image in UN specific patterns of pixels that applies to a particular person. Signature verification problem, therefore, is concerned with determining particular signature is really the person or not.

The signature is a special case of handwriting, in which the special characters and has a right to exist. Signature verification is difficult to image recognition as because no two genuine signatures of the person, is not exactly the same. His difficulty is that great fakes along the same lines as opposed to the original fingerprints fingerprint, Iris and iris or from two different individuals can vary widely. Ideally, the interpersonal differences are much greater than the realization should not BE changes. Therefore, it is important to identify and extract the features that Those changes and to minimize and maximize the interpersonal intrapersonal variations. There are two approaches to the verification of signatures, online and offline Differential date Purchased by the way. If there is no signature, resulting on a sheet of paper, and then scanned. While the online case is electronic signature Tablet and pen. Obviously, dynamic information, like speed, pressure is lost in homes as opposed to stand-alone houses on the Internet.
