Single Input Multi Factor User Authentication Protocol for Smartphone (original) (raw)

Smart phones are increasingly becoming a tool for ubiquitous access to a number of services including but not limited to e-commerce and home banking, and are more and more used for sensitive data storage. If on the one hand this makes the smartphone a powerful tool in our private and professional life, on the other it has brought about a series of new challenging security and privacy threats and raised the need to protect users and their data through new secure authentication protocols. In this article, we illustrate how the security level of a human authentication system increases from traditional systems based on the use of passwords or badges to modern systems based on biometrics. We have moved a step forward by conceiving an authentication protocol based on the combined recognition of human face, voice and smartphone fingerprint.
