Glove-Based Approach to Online Signature Verification
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2008Utilizing the multiple degrees of freedom offered by the data glove for each finger and the hand, a novel on-line signature verification system using the Singular Value Decomposition (SVD) numerical tool for signature classification and verification is presented.

Online Signature Verification on Mobile Devices
IEEE Transactions on Information Forensics and Security, 2014This paper studies online signature verification on touch interface-based mobile devices. A simple and effective method for signature verification is developed. An online signature is represented with a discriminative feature vector derived from attributes of several histograms that can be computed in linear time.

Reliable online human signature verification systems
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1996Online dynamic signature verification systems were designed and tested. A database of more than 10,000 signatures in (x(t), 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 ...

Recurrent Adaptation Networks for Online Signature Verification
IEEE Transactions on Information Forensics and Security, 2019Online signature verification remains a challenging task owing to large intra-individual variability. To tackle this problem, in this paper, we propose to use recurrent neural networks (RNN) for representation learning in the dynamic time warping framework. Metric-based loss functions are designed explicitly to minimize intra-individual variability and

Signature barcodes for online verification
Pattern Recognition, 2022Abstract As a sub-branch of behavioral biometrics, online signature verification systems deal with unique signing characteristics, which could be better differentiated by extraction of habitual singing styles instead of geometric features in case of perfect forgery. Even if the signatures are geometrically identical, speed and frequency components of

Online Signature Verification system
2009 5th International Colloquium on Signal Processing & Its Applications, 2009Online Signature Verification is a process of verifying the writer's identity by using signature verification system. This system can be use as a security system such as verification for assessing entry application and password substitutions. Signature verification technology requires primarily a digitizing tablet and a special pen connected to the ...

Velocity-Image Model for Online Signature Verification
IEEE Transactions on Image Processing, 2006In general, online signature capturing devices provide outputs in the form of shape and velocity signals. In the past, strokes have been extracted while tracking velocity signal minimas. However, the resulting strokes are larger and complicated in shape and thus make the subsequent job of generating a discriminative template difficult. We propose a new

A Multi-stage Online Signature Verification System
Pattern Analysis & Applications, 2002: This paper presents a new three-stage verification system which is based on three types of features: global features; local features of the corner points; and function features that contain information of each point of the signatures. The first verification stage implements a parameter-based method, in which the Mahalanobis distance is used as a ...

Online Signature Verification using Deep Descriptors
2020 Conference on Information Communications Technology and Society (ICTAS), 2020Signature verification is a technique used to counter signature forgery. In the past, the process began with staff at a bank, who is an expert, would confirm if a signature is genuine or forged. With the development of technology, now people no longer sign on paper, rather on a digital pad which can take more data which is recorded on paper, for ...

Online Signature Verification Based on Generative Models
IEEE Transactions on Systems, Man, and Cybernetics, Part B (Cybernetics), 2012The success of generative models for online signature verification has motivated many research works on this topic. These systems may use hidden Markov models (HMMs) in two different modes: user-specific HMM (US-HMM) and user-adapted universal background models (UBMs) (UA-UBMs).
