Automatic off-Line Signature Verification Systems: A Review
نویسندگان
چکیده
The use of biometric technologies for human identity verification is growing rapidly in civilized society and showing its advancement towards the usability of biometrics for security. Off-line signature verification is considered as a behavioral characteristic based biometric trait in the field of security and the prevention of fraud. So, offline signatures are extensively used as a means of personal verification and identification. Manual signature-based authentication of a large number of documents is a very difficult and time consuming task. Consequently for many years, in the field of protected communication and financial applications, we have observed an explosive growth in biometric personal authentication systems that are closely connected with measurable physical unique characteristics (hand geometry, iris scan, finger prints or DNA).. Human signatures also provide secure means for confirmation and authorization in legal documents. So nowadays, automatic signature verification becomes an essential component. In order to convey the state-of-the-art in the field to researchers, in this paper we present a survey of off-line signature verification systems. General Terms: Systems, Forgeries, Methods, Skilled,

A General Approach to Off-line Signature Verification
Although automatic off-line signature verification has been extensively studied in the last three decades, there are still a huge number of open questions and even the best systems are still struggling to get better error rates than 5%. This paper targets some of the weak spots of the research area, which are comparability, measurability and interoperability of different signature verification ...
متن کاملStatistical Features Based Off Line Signature Verification System using Image Processing Techniques
Handwritten signature recognition can be divided into online (or dynamic) and off-line (or static) recognition. Online recognition refers to a process that the signer uses a special pen called a stylus to create his or her signature, producing the pen locations, speeds and pressures, while off-line recognition just deals with signature images acquired by a scanner or a digital camera. In genera...

ـــ ـ Automatic signature verification is a wellestablished and an active area for research with numerous applications such as bank check verification, ATM access, etc. Most off-Line signature verification systems depend on pixels intensity in feature extraction process which is sensitive to noise and any scale or rotation process on signature image. This paper proposes an off-line handwritten ...
متن کاملOff-Line Signature Verification: A Comparison between Human and Machine Performance
When a large number of documents, e.g. bank cheques, have to be authenticated in a limited time, the manual verification of, say the authors’ signatures, is often unrealistic. This led to the development of a wide range of automatic off-line signature verification systems. However, the value of such a system is rarely demonstrated by conducting a subjective test. We recently developed a novel o...
