Abstract
Audio and video sensors are useful in Active Assisted Living (AAL) systems as they provide a rich source of information in well-known formats and since such sensors are readily available. This, however, also means that audio and video sensors will record a wide range of private information. Misusing this private information can have far-reaching consequences, including extortion, theft, and harassment. This chapter provides an overview of privacy issues in video and audio from the perspective of AAL systems and the most important protections for privacy.
