A study on enhanced dynamic signature verification for the embedded system

This paper is a research on the dynamic signature verification of error rate which are false rejection rate and false acceptance rate, the size of signature verification engine, the size of the characteristic vectors of a signature, the ability to distinguish similar signatures, and so on. We suggest feature extraction and comparison method of the signature verification. Also, we have implemented our system with Java technology for more efficient user interfaces and various OS Platforms and embedded system.

A Study on an Advanced Evaluation Method for Dynamic Signature Verification System

This paper is a research on an evaluating method for the dynamic signature verification system. It is described about various factors such as error rate, the size of signature verification engine, the size of the characteristic vectors of a signature, the ability to distinguish similar signatures, the processing speed of signature verification and so on. This study identifies factors to consider in evaluating signature verification systems comprehensively and objectively without an officially approved signature database, examines the meaning of each of the factors, and proposes criteria for evaluating and analyzing the factors.

An Enhanced Dynamic Signature Verification System for the Latest Smart-Phones

We propose an algorithm for dynamic signature verification using the latest Smart-phones such as iPhone, android phone and MS windows phone. Also, we suggest simple signature patterns, the performance of a dynamic signature verification system, which determine the authentication of signatures by comparing and analyzing various dynamic data such as shape of the signature, writing speed, slant of shape, and the order and number of strokes for personal signatures for the smart-phones. In ubiquitous society, the smart-phone will be very important portable device for the mankind.

A Study on Modified DTW for the Dynamic Signature Verification

This paper deals with a modified method of the dynamic time warping and feature points to extract various important information of the signature for the dynamic signature verification. We could achieve lower equal error rate, small and efficient feature points and fast processing time for the notification.
