A survey on offline handwritten signature verification system using writer dependent and independent approaches

Handwritten signature verification systems are studied using On-line and Off-line approaches. Due to the lack of dynamic information, Off-line signature verification systems are more difficult to compare to On-line verification systems. There are two different approaches to deal with the problem of off-line signature verification. The first one is the writer dependent model (also known as personal model) and other is writer independent model (also known as global model). This paper presents a survey of off-line handwritten signature verification systems using writer dependent (WD) and writer independent (WI) approaches. Many recently used approaches of verification systems have been investigated. A conclusion of all these works and an outlook into the future work is also presented in this paper.
