In this paper, we propose a system architecture with disclosure control for aggregating multi-user life logs. The miniaturization of mobile terminals with various sensors has made it possible to collect life logs in everyday life. While current location based services use GPS data only for estimating users’ location, collaborative filtering with multi-user’s life log and extraction of collective knowledge from life logs are expected to improve the services. In order to accomplish life log services using multi-user’s life logs, we propose a system architecture which consists with a local system for each user and an aggregated life log system. The local system includes a disclosure control function and the aggregated life log system has a function for accumulating and processing huge amount of life logs. We prototype this architecture and implement several life log services. |
