The problem of signature verification is in theory a pattern recognition task used to discriminate two classes, original and forgery signatures. Even after many efforts in order to develop new verification techniques for static signature verification, the influence of the forgery types has not been extensively studied. This paper reports the contribution to signature verification considering di...

Handwritten Signature Verification (HSV) is a natural and trusted method for user identity verification. HSV can be classified into two main categories: offline and online HSV. Offline systems take handwritten signatures from scanned documents, while online systems use specific hardware (e.g., pen tablets) to register pen movements during the act of signing. Online HSV systems may embed signatu...

Some of the biometrics used in identity verification, such as face, iris or fingerprint, have small fixed size pattern vectors which can easily be stored for rapid scoring. Important dynamic biometrics such as voice and signature, however, have much larger and variable sized feature vectors which require far greater verification computation. Such dynamic biometrics cannot therefore normally be ...

The paper presents an off-line signature verification system using support vector machine technique. Global features are extracted from the signatures using radon transform. For each registered user in the system database a number of reference signatures are enrolled and aligned for statistics information extraction about his signature. Dynamic time warping algorithm is used to align two signat...

Handwritten signature is the most widely accepted biometric for identity verification. To facilitate objective evaluation and comparison of algorithms in the field of automatic handwritten signature verification, we organized the First International Signature Verification Competition (SVC2004) recently as a step towards establishing common benchmark databases and benchmarking rules. For each of...

The person’s signature is an important biometric attribute which is used for authentication and identification of individual. Today, Signature verification is one of the most important features. There are many parameters for security checking like password, pin code, but signature recognition is the very popular because it is quite accurate and cost efficient too. On the other hand, it’s very d...

In the era of emergent technology, security is that the foremost anxiety to avoid replicas and counterfeits. There are diverse Biometric systems that enable in personal identification, amongst those verification systems, one system is Signature Verification System. Signatures are substantiated discrimination on-line and offline systems. Every human being has their own writing style and hence th...

This work is focused on dynamic signature verification for state-of-the-art smart phones, including performance evaluation. The analysis was performed on database consisting of 25 users and 500 signatures in total acquired with Samsung Galaxy Note. The verification algorithm tested combines two approaches: feature based (using Mahalanobis distance) and function based (using DTW), and the result...

We propose an efficient batch signature generation scheme for signing multiple messages simultaneously. The scheme can be based on any signature scheme with appendix and resultant signatures preserve the property of independent verification by different recipients. The scheme is shown to be of almost constant complexity for both generation and verification as the number of messages increases wh...

paper presents a new approach for static signature verification based on optical flow. In the first part of the paper, optical flow is used for estimating local stability of static signatures. In the second part, signature verification is performed by the analysis of optical flow, using an alternating decision tree. The experimental tests, carried out on signature of the GPDS database, demonstr...
