Lifelog Event Management: Crowd Research Case Study

Lifelog research involves complex event analysis that re- quires the efforts of many advanced experts in different disci- plines. It also handles privacy and/or copyrighted materials where mutual consent on the use of data is very important. Thus we propose a secure Web-based lifelog database ser- vice to help researchers concentrate efforts to solve difficult research issues. This paper details many aspects of lifelog research topics and technical challenges that the author has experienced over one year case study. It also describes eco- nomical and efficient methods to implement the back-end system and services for real lifelog event management.
