Activity Modeling and Threat Taxonomy for Context Aware Proactive System (CAPS) in Smart phones

Mobile technology and Internet is becoming an integral part of our daily life. Widespread usage of smart phones and its greater in-built functionality have provided portability to perform transaction like shopping, ticket booking and banking transactions on the fly. In mobile computing, the characteristic like context awareness allows to provide proactively adapted services to user according to the context. Especially in combination with mobile devices, these mechanisms carries high value and are used to increase usability tremendously. Equally being an Android operating system as open source, it is prone to attack. In this view there is need to define new attack taxonomy and its modeling. This paper presents a novel taxonomy for Context Aware Proactive System (CAPS) in smart phone. This paper also presents activity modeling of proposed taxonomy to get an actual view of happening of attack like Cross Service attack, spyware and Battery Exhaustion attack. At the end this paper also discusses mitigation techniques to address few of the mentioned attacks.
