Smart device oriented intelligent context-awareness system for U-SAFE service using object oriented modeling technique

Abstract

Smart phone technology has the potential to improve crime figures by preventing certain crimes altogether or diminishing their frequency or severity. Elementary school sexual assault incidents as well as female serial murder cases have captured the public's attention, and when facing such social hazards, the user with a smart mobile device that is equipped with fusion technology may evade physical harm or evade the danger altogether. This paper discusses the components of context awareness system for this purpose and describes a putative implementation on a phone. The u-SAFE service aims to fight crime when it inputs phone sensing information (audio, video, image) and performs context acquisition and analysis, and pattern analysis of data tempered by knowledge of the user's activity history. © 2011 Springer-Verlag.
