A Preliminary Study on Various Off-line Hand Written Signature Verification Approaches
Biometrics can be classified into two broad categories— behavioral (signature verification, keystroke dynamics, etc.) and physiological (iris characteristics, fingerprint, etc.). Handwritten signature is amongst the first few biometrics to be used even before the advent of computers. Signature verification is widely studied and discussed using two approaches [5]. On-line approach uses an electr...
متن کاملClassification Approaches in Off-Line Handwritten Signature Verification
The aim of off-line signature verification is to decide, whether a signature originates from a given signer based on the scanned image of the signature and a few images of the original signatures of the signer. Although the verification process can be thought to as a monolith component, it is recommended to divide it into loosely coupled phases (like preprocessing, feature extraction, feature m...
متن کاملA Survey on Off-line signature Recognition and Verification Schemes
The signature Recognition and verification system is used to recognize and verify individual’s handwritten signature. Now a day’s handwritten signature is one of the most widely accepted personal attributes for identity verification. Signature verification provides authorization in financial and business transaction. Signature verification finds its application in the field of net banking, pass...
متن کاملA Hybrid On/Off Line Handwritten Signature Verification System
This paper proposes a new hybrid handwritten signature verification system where the on-line reference data acquired through a digitizing tablet serves as the basis for the segmentation process of the corresponding scanned off-line data. Local foci of attention over the image are determined through a self-adjustable learning process in order to pinpoint the feature extraction process. Both loca...
متن کاملFeature matching in off-line signature verification
The last three decades of research brought many improvements in the field of signature verification. On-line signature verification already has several commercial applications. However, the off-line verification problem is much harder to tackle. One of the tasks is the identification and matching of coherent shapes in different images, which can be a key factor in imporving existing systems. Th...
