Abstract: A mark or sign made by an individual on an instrument or document to signify knowledge, approval, acceptance or obligation is called as signature. Signature recognition is a behavioral biometric that identifies an individual on the basis of their handwritten text. There are two types of signature verification systems which are offline (static) and online (dynamic). When a person does a signature on a paper or on a document then it is called offline or static signature. The offline signatures images are obtained by scanner or captured by a camera. It is used in several documents and many different official purposes. Hand written signature is a common biometric used in transaction as a general authentication like bank cheques and credit cheques. Mainly biometric identification has two phase 1) recognition and 2) verification. Online signature is captured by pen based tablet and also depends on the pressure of the pen, ups and downs of the pen and time stamping. Online signature is more trustworthy and accurate but offline handwritten signature is more user friendly than online signature.
