in the ecosystem. In this interconnected
world, smart objects have an important role in giving users the chance for life-logging in
smart environments. However, smart devices have several limitations with regards to
memory, resources and computation power, hindering the opportunity to apply wellestablished
security algorithms and techniques for secure life-logging on the Internet of
Things (IoT) domain. The need for secure and trustworthy life-logging in smart environments
is vital, thus, a lightweight approach has to be considered to overcome the
constraints of Smart Objects. The purpose of this paper is to present in details the 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. In order to investigate the efficiency of the lightweight framework
and the impact of the security attacks on energy consumption, an experimental test-bed
was developed including two interconnected users and one smart attacker, who
attempts to intercept transmitted messages or interfere with the communication link.
Several mitigation factors, such as power control, channel assignment and AES-128
encryption were applied for secure life-logging. Finally, research into the degradation of
the consumed energy regarding the described intrusions is presented.
