Restrain from pervasive logging employing geo-temporal policies

Life logging has been a prominent research concern in recent years with the invention of wearable life capture gadgets and it has played a significant role in some situations such as helping Alzheimer disease patients. However, at the same time, it has raised privacy concerns among ordinary people. At present, life log devices are pervasively capturing information, including people in the vicinity without their consent. This will produce a great concern in the future if the majority of people come to have life log devices that record continuously what is happening around. In this paper, we propose a mechanism to restrict people from capturing a person in their personal digital diaries in real time by introducing Geo-temporal privacy framework. Furthermore, the system ensures that the unwilling party is not revealed to the life logging system users and privacy is sustained when the Geo-temporal framework discontinues the log activity after an encounter with the reluctant party. The prototype is developed on an Android-based smart phone that works as a life log device with a policy controller. The phone is connected to an Infrared Transmitter/Receiver with an interface board, for identifying human proximity.
