Abstract

The recent proliferation of digital cameras and smart phones with camera devices permits an enduser to record the flow of everyday events and experiences. A vast amount of daily activity record,called lifelog, is a valuable resource for health examination. The advent of lifelogging technologyhas been changing the uses as well as the paradigm of healthcare services, and emphasizing theimportance of services being personalization. To provide accurate personalized healthcare service,it is necessary to gather as much personal lifelog data as possible about patients. However, as theamount of lifelog data becomes vast, it requires an efficient way to manage and store such vastinformation. In this paper, we propose a selective lifelog management scheme based on thecharacteristics of collected data in hierarchical lifelog system. In our proposed scheme, theavailable storage for the preprocessing of lifelog data is selected to optimally utilize computing andstorage resources. The analytical results show that our approach achieves better performance than that of the existing lifelog management scheme by the selective lifelog management scheme.
