-This paper describes a technique for on-line signature verification using Hidden Markov Models (HMMs). Signatures are captured and digitized in real-time using a graphic tablet. For each signature a HMM is constructed using a set of sample signatures described by the normalized directional angle function of the distance along the signature trajectory. The Baum-Welch algorithm is used for both ...

Signature verification is the process carried out to determine whether a given signature is genuine or forged. Handwriting comes in many different forms and there is great deal of variability even signature of people that use same language. Some signature may be quite complex while others are simple and appear as if they may be forged easily. In this paper we present an effective method to perf...

Face and signature are still two most dominant authentication modes in banking, legal documents, or personnel records in spite availability of more robust biometric modes. Hence, it is imperative to develop low-cost and reliable automated face recognition and signature verification system. Therefore, this paper presents our work in development of a two-in-one portable low-cost dsPIC30F3013 digi...

Key substitution vulnerable signature schemes are signature schemes that permit an intruder, given a public verification key and a signed message, to compute a pair of signature and verification keys such that the message appears to be signed with the new signature key. Schemes vulnerable to this attack thus permit an active intruder to claim to be the issuer of a signed message. A digital sign...

Handwritten Signature verification is a biometric technique that is useful because signatures are in many practices accepted as a means of identity verification. This work approaches signature verification using seprate filters with different approaches. In the first, global features of the signature, such as average velocity are considered using a Euclidian distance. In the second filter, loca...

This paper specifies how biometric verification methods can be applied in addition to PIN verification on digital-signature smart cards in compliance with established smart-card standards. After successful PIN verification, multiple digital signatures can be created; each signature creation, however, is preceded by biometric verification.

-Authentication of identity is rapidly becoming an important issue. Signature verification is a promising biometric authentication method for resolving this issue. This paper proposes a new on-line signature verification algorithm that utilizes only pen position trajectories. The algorithm is an improvement in our previous work [9]. In preliminary experiments, the equal error rate (EER) was 1.2...

The most widely accepted bio-metric for identification and authentication of a person are signatures. Signature verification is a technique used by banks, intelligence agencies and high-profile institutions to validate the identity of an individual. There are various techniques for signature verification, both online and offline. This paper aims at providing detailed overview on different signa...

Signature recognition is probably the oldest biometrical identification method, with a high legal acceptance. Verification can be performed either Offline or Online based on the application. Online systems use dynamic information of a signature captured at the time the signature is made. Offline systems work on the scanned image of a signature. We have worked on the Offline Verification of sign...
