Online Signature Verification: A Survey on Authentication in Smartphones

Smart phones are advance generation of mobile phones. They enable us to access a large variety of services like data storages, voice communication, wireless connectivity etc. As the number of services increased the number of vulnerabilities and attacks has been increasing as well. There has been a corresponding rise of security solution proposed by researchers for authentication in smart phones like password, face and voice recognition, secret path and signature verification. The most popular authentication mechanism is online biometric signature verification. People adopt this mechanism due to its nature which is most fashionable, secure, trustable and difficult for unauthorized persons to breach privacy. With this work, we aim to provide a structured and broad over view of the research on signature verification process for authentication in smart phones. This paper surveys on signature verification process in smart phones, by focusing on different techniques used in signature verification process. We grouped existing approaches aimed to analyze performance and accuracy rate of different approaches adopted by signature verification process in smart phones. With this categorization, we aim to provide an easy and concise view of different approaches adopted by signature verification process in smart phones.
