Review on the Security Related Issues in Context Aware System

Abstract

A context aware system is recognized as a “system which uses any context information previous to, or in the duration of, service stipulations”, whereas the main goal of this system is to track and identify the users. The mobility feature of most computing and personal assistance devices have made the ‘context of the user’ an important aspect of the system, affecting its development process in terms of end-user requirements and system behaviour. Context Aware Systems are different from traditional systems as they provide unique features such as heterogeneity, high complexity and artificial intelligence. Since the parameters that constitute a context aware system, such as location and time of the day are rapidly changing. The use and importance of this system is increasing and therefore becoming a major part in prospective wireless systems. However, beside the numerous advantages, context-aware systems have also come up with the numerous issues and challenges related to privacy and security of the user’s information in these systems. Therefore, this paper is mainly aimed at a review of the security and privacy issues related with context-aware systems. It also gives a brief introduction regarding the preferred and suitable frameworks required to implement the security requirements. It further focuses on the main question for most researchers about the frameworks used for context-aware systems
