What is Ambient Assisted Living

Developed societies are registering a dramatic change in terms of population evolution, the most important fact being the ageing population. An alarming fact is that the birth-rate is dropping very fast, inverting the ageing pyramid that used to have a higher incidence on the young population, now having a higher incidence in the older population. In the quest to provide answers to some problems the elderly population has, applications and projects arise from the Ambient Assisted Living area, providing services that help the user in his daily life, providing the needed help and trying to be as non-invasive as possible. The fact is that these systems operate optimally by using information about the user, assisting him according to his preferences. The data gathered for such events is highly personal and sensitive. This can cause a loss of privacy and affect personal data. In this chapter, the authors present an Ambient Assisted Living project towards assistance to an elderly population. The problems and possible solutions in the legal area towards loss of privacy and personal data and information use is also covered.
