Flow and Threat Modelling of a Context Aware System

1. Context Awareness

The depiction of applications, devices and human users present in an environment is first identified by Schilit and refers to the smart classification of the activity or ‘Context’ (Schilit, Hilbert, & Trevor, 2002). The context includes spatial, temporal and deduced information within an activity, describing the people, the computational devices and the services present within an environment (Mokhtar, Foumier, Georgantes, & Issamy, 2006). Context awareness is the ability of systems to identify the users context and adapt services based on their needs. Since Weiser’s vision, context aware computing has evolved from context aware applications to platforms that classify current activity based on the context (Strang & Linnhoff-Popien, 2004; Weiser, 1991; Mahmud & Javed, Context Inference Engine (CiE): Classifying Activity Of Context Using Minkowski Distance And Standard Deviation Based Ranks, 2014).
