Life-logging in smart environments: Challenges and security threats

As the world becomes an interconnected network in which objects and humans interact, new challenges and threats appear. In this interconnected world, smart objects seam to have an important role in giving users the chance for life-logging in smart environments. However, the limitation of smart devices with regard to memory, resources and computation power, hinder the opportunity to apply well-established security algorithms and techniques for secure life-logging on the Internet of Things domain. As the need for secure and trustworthy life-logging in smart environments is vital, a lightweight approach has to be considered to overcome the constraints of smart objects. The purpose of this paper is to detail current topics of life-logging in smart environments while describing interconnection issues, security threats and suggesting a lightweight framework for ensuring security, privacy and trustworthy life-logging.
