Abstract

Automatic signature verification is a biometric method that can be applied in all situations where handwritten signatures are used, such as cashing a check, signing a credit card, authenticating a document, and others. Over the last two decades, several innovative approaches for off-line signature verification have been introduced in literature. Therefore, this chapter presents a survey of the most important techniques used for feature extraction and verification in this field. The chapter also presents strategies used to face the problem of a limited amount of data, as well as important challenges and research directions.
