Mobile devices are getting very popular these days. Most of people use mobile phones and now, as the new generation of smartphones, the capabilities that are included in a portable palmtop device are amazing. However, single user authentication is not enough as their compact size makes them easy to be stolen. The variety of frauds on these devices has lead to the development of an intrusion detection system, that acts as a constant and transparent authentication mechanism.In this paper an algorithm for host based intrusion detection in mobile devices has is developed. Normal Intrusion Detection Systems use signature checking algorithms, something that can not be implemented easily on a mobile device. This system is based on statistical models that try to identify anomalies in users’ attitude by utilizing a profiling procedure and then requires a second layer of authentication from the user, where at the same time network administrator is warned about possible abuse.
