چکیده
Biometrics authentication has been gaining popularity among the industries that highly incorporate securities in their daily activities. Signature verification is one of the biometrics authentication techniques which has been used for years and publicly accepted. The ease of use of signature verification coupled with lower cost and technology advances in tablet technologies, signature verification has been adapted into applications such as credit cards transactions, checks transactions and documents verification. This paper focuses on the development of an online signature verification using Dynamic Time Warping (DTW) algorithm. The developed system would be fully described in the relevant sections as well as the techniques and implementations involved. The developed system was tested on a database in the purpose to evaluate the performance of the system. The database used in the system is obtained from Signature Verification Competition 2004 (SVC2004) which consists of genuine signatures and skilled forgery signatures. The equal error rate (EER) obtained after some experiments is 0.15 using universal threshold and 0.135 using user-based threshold with the implementation of Dynamic Time Warping (DTW) algorithm.

متن کاملOnline signature verification using a new extreme points warping technique
There are two common methodologies to verify signatures: the functional approach and the parametric approach. In this paper, we propose a new warping technique for the functional approach in signature verification. The commonly used warping technique is dynamic time warping (DTW). It was originally used in speech recognition and has been applied in the field of signature verification with some ...
متن کاملIdentity authentication using improved online signature verification method
We present a system for online handwritten signature verification, approaching the problem as a two-class pattern recognition problem. A test signature s authenticity is established by first aligning it with each reference signature for the claimed user, using dynamic time warping. The distances of the test signature to the nearest, farthest and template reference signatures are normalized by t...
متن کاملDynamic Signature Verification using Local and Global Features
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...
متن کاملFusion of Local and Regional Approaches for On-Line Signature Verification
Function-based methods for on-line signature verification are studied. These methods are classified into local and regional depending on the features used for matching. One representative method of each class is selected from the literature. The selected local and regional methods are based on Dynamic Time Warping and Hidden Markov Models, respectively. Some improvements are presented for the l...
