A secure Ambient Assisted Living (AAL) environment: An implementation view

T Subjects such as knowledge engineering, pervasive computing, unified communication, ubiquitous sensing and actuation and situation awareness are gaining the most critical and crucial attention from information technology (IT) professionals and pundits across the globe these days in order to accomplish the vision of ambient intelligence (AmI). It is all about effective and round-the-clock gleaning of data and information from different and distributed sources. Secondly whatever is gathered, transmitted, and stocked are being subjected to a cornucopia of tasks such as processing, mining, clustering, classification, and analysis for the real-time and elegant extraction of hidden actionable insights. Based on the knowledge extracted and the needs identified, the final tasks is decide and initiate the next course of actions in time. Not only information, interaction and transaction, but also physical services can be conceived, constructed and supplied to human users with the stability and maturity AmI technologies and instrumented, interconnected, and intelligent devices. This paper gives the detailed description of an AmI application which can provide impenetrable and unbreakable security, convenience, care and comfort for the needy. Our focus here is to develop a secure and safety-critical Ambient Assisted Living (AAL) environment which can monitor the patient's situation and give timely updates. In order to fulfill all these needs, a smart environment has been created to effectively and insightfully control patients' needs. The middleware standard preferred for the development and deployment a bevy of ambient and articulate services is Open Service Gateway Initiative (OSGi).
