Power Based Malicious Code Detection Techniques for Smartphones

In recent years there have been a growing number of viruses, root kits, and malware designed to gain access to system resources and information stored on smartphones. This paper examines the effectiveness of two smartphone-specific techniques for detecting malicious code behavior based on individual power consumption profiles based on time and location. Prototypes for each of the techniques were developed for use with Google´s Android platform and were each evaluated over periods of six months or more involving several real-world users. This paper describes the design and implementation of each of these prototypes as well as the evaluation of their results.
