Online signature verification is a challenging problem. It’s difficulty comes from the problem of separation between genuine variation of an individual’s signatures and that of forgery signatures. Different algorithms have been proposed by various researchers, however lack of the publically available signature databases hinders benchmarking their performances. In this paper we introduce a signa...

The human signature is still the most widely used and accepted form of personal authorisation and verification applied to documents and transactions. In this paper we describe the design and implementation of a flexible and highly configurable framework for the experimental construction and performance investigation of biometric signature verification systems. We focus on a design approach whic...

This paper proposes a designated verifier signature scheme based on the Schnorr signature and the Zheng signcryption schemes. One of the advantages of the new scheme compared with all previously proposed schemes is that it achieves the “strong designated verifier” property without encrypting any part of the signatures. This is because the designated verifier’s secret key is involved in the veri...

A study of online signature verification has been carried out based on experimental evaluation. We started by presenting a brief survey of the recent literatures on important factors of online signature verification. Four main issues have been addressed in the work: 1) assessment for signature consistency caused by different physiological factor. 2) Analysis for variation and complexity of onli...

In this paper we propose a new voting scheme that provides a receipt to each voters. The receipt is build in a way that prevents that the vote can be revealed to third entities other than a judge. The scheme is based on the concept of strong designated verifier signature scheme and threshold RSA signatures. The signing key size remains bounded by the size of a RSA modulus. The computational cos...

Hand written Signature used as a biometric symbol for various application. Each signature signed by everyone may be distinct at a similar time. So it’s important to have a web processed signature Verification system for differentiate digital signature. A variety of studies regarding off line and online verification systems are introduced by researchers within the last years. The paper provides ...

In this article, we proposed a batch verification scheme for multiple proxy signatures to reduce the proxy signature verification time. The proposed scheme is not only efficient because it does not verify each individual proxy signature separately, but also secure because it can detect forged multiple proxy signatures without failure.
