This paper deals with an off-line Japanese signature verification using a pattern matching method. An annoying problem encountered in off-line signature verification using a pattern matching is that variation of signature stroke widths and a registered signature selected from a set of reference samples affect the verification performance. In this paper, we propose a modified pattern matching me...

ER (Extended R-squared) is proposed as a similarity measure for on-line signature verification. SLR (Simple Linear Regression) defines R as a measure of goodnessof-fit. We observed that R is a good similarity measure for 1-dimensional sequences. However, many kinds of sequences are multidimensional, such as on-line signature sequences, 2D curves, etc. Therefore, we extend R to ER for multidimen...

In this work we present a strategy for off-line signature verification. It takes into account a writer-independent model which reduces the pattern recognition problem to a 2-class problem, hence, makes it possible to build robust signature verification systems even when few signatures per writer are available. Receiver Operating Characteristic (ROC) curves are used to improve the performance of...

The signatures are one of the ways to identify the signer. Signature recognition is the process of verifying the person’s identity by checking their signature with the signatures which are stored in the database. This process is of two types: offline and online. This paper deals with the offline technique. This technique recognizes the person whether he/she is genuine or forged. In this paper t...

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...

This paper proposes a stroke extraction method for use in off-line signature verification. After giving a brief overview of the current ongoing researches an algorithm is introduced for detecting and following strokes in static images of signatures. Problems like the handling of junctions and variations in line width and line intensity are discussed in detail. Results are validated by both usin...
