Online signature verification by spectrogram analysis
Applied Intelligence, 2017The concept of electronic signatures emerged decades ago, however they are still not prevalent due to lack of reliable infrastructure. Although the signatures are hard to perfectly imitate, it is simple with an image editing software to copy the original signature and paste on a document.

Online signature verification using GA-SVM
2011 International Conference on Image Information Processing, 2011This paper presents an online signature verification system based on Genetic Algorithm-Support Vector Machine (GA-SVM). The raw information, obtained from SVC 2004 database, as time functions is used to derive 75 features. Six different groups of features have been generated from 75 features and their performance evaluated using SVM.

EXPLOITING STABILITY REGIONS FOR ONLINE SIGNATURE VERIFICATION
2014We present a method for finding the stability regions within a set of genuine signatures and for selecting the most suitable one to be used for online signature verification. The definition of stability region builds upon motor learning and adaptation in handwriting generation, while their selection exploits both their ability to model signing habits ...

Uniform segmentation in online signature verification
2015 Annual IEEE India Conference (INDICON), 2015In this paper, an online signature verification system based on the segmentation of online signature is proposed. The two set of features i.e shape features and dynamic features are extracted and a feature vector concatenating these two set of features is obtained.

Online/Offline Verification of Short Signatures
2011Fast signature verification is desirable in many applications, especially when signature recipients need to make response quickly. In this paper, we present an efficient online/offline verification of short signature (OVS) scheme without random oracles.

Online signature verification using hybrid features
2015 Second International Conference on Information Security and Cyber Forensics (InfoSec), 2015Biometrics is the process by which a person's physical, behavioral and psychological traits are identified and recorded by an electronic device of identity.Online handwritten signature verification is a biometric based security system. Most of the previous work is based on statistics of online signatures, local and global features.

Distance based verification techniques for online signature verification system
2015 2nd International Conference on Recent Advances in Engineering & Computational Sciences (RAECS), 2015This paper presents different distance based verification techniques for online signature verification system. For the purpose of extracting the features of the signature, histogram feature extraction technique is used. Each signature is symbolized as a feature vector. In case of verification of the online signature three different distance calculation

Online signature verification modeled by stability oriented reference signatures
Information Sciences, 2018Abstract Signature verification is widely used in the fields of finance, access control and security. However, one of the biggest problems associated with signature verification is its instability. This instability may concern specific fragments of a signature or its entirety.

Detecting forgeries and disguised signatures in online signature verification
Qatar Foundation Annual Research Forum Volume 2012 Issue 1, 2012Online signatures are acquired using a digital tablet which provides all the trajectories of the signature, as well as the variation in pressure with respect to time. Therefore, online signature verification achieves higher recognition rates than offline signature verification.

Online Handwritten Signature Verification for Low-End Devices
2017Handwritten Signature Verification (HSV) systems are widely used to verify the authenticity of a user signature automatically. In offline systems, the handwritten signature (represented as an image) is taken from a scanned document, while in online systems, pen tablets are used to register the signature, characterized by several dynamics (e.g., its ...
