The Modified DTW Method for On-Line Automatic Signature Verification
Dynamic Programming Matching (DPM) is a mathematical optimization technique for sequentially structured problems, which has, over the years, played a major role in providing primary algorithms in pattern recognition fields. Most practical applications of this method in signature verification have been based on the practical implementational version proposed by Sakoe and Chiba [1], and is usuall...
متن کاملPractical On-Line Signature Verification
A new DTW-based on-line signature verification system is presented and evaluated. The system is specially designed to operate under realistic conditions, it needs only a small number of genuine signatures to operate and it can be deployed in almost any signature capable capture device. Optimal features sets have been obtained experimentally, in order to adapt the system to environments with dif...
متن کاملDWT Domain On-Line Signature Verification
Biometrics attracts attention since person authentication becomes very important in networked society. As the biometrics, the fingerprint, iris, face, ear, vein, gate, voice and signature are well known and are used in various applications (Jain et al., 1999; James et al., 2005). Especially, assuming mobile access using a portable terminal such as a personal digital assistant (PDA), a camera, m...
متن کامل7 Automatic on - Line Signature Verification
Signature verification is an art: Whereas we may bring objective measures to bear on the problem, in the final analysis, the problem remains subjective. This art is both well studied and well documented as it applies to the verification by humans of signatures whose only records are visual [13,5,10] — that is, as it applies to signatures during whose production no measurement is made of the pen...
متن کاملReliable On-Line Human Signature Verification Systems
On-line dynamic signature verification systems were designed and tested. A data base of more than 10,000 signatures in (I, y(t))-form was acquired using a graphics tablet. We extracted a 42-parameter feature set at first, and advanced to a set of 49 normalized features that tolerate inconsistencies in genuine signatures while retaining the power to discriminate against forgeries. We studied alg...
