Behavior Fingerprints Based Smartphone User Authentication - A Review.

Nowadays, humans have become too dependent on their smartphone devices for a broad range of tasks: shopping, bank interactions, socialization …etc. Wide-speared dependence on smartphone devices raises numerous security and privacy risks. To deal with these evolving threats, various authentication methods based on user behavioral biometrics have been proposed in recent research. Behavioral biometrics are used to identify the smartphone user continuously without seeking his/her cooperation which makes the task more convenient. In this paper, we review the current behavioral biometrics authentication methods on smartphones. We present an analytical study of several proposed mechanisms and discuss the strengths and limitations of available approaches. A comparative evaluation of the various state of the art obtained results is discussed. Finally, a list of open problems, challenges, and future directions are carried out for future studies on this research area.
