- Abstract
- These days lifelog data collected from smartphones provide a substantial amount of information that helps to enhance personalized medical services. Because of the high dependency on smartphones, however, there are some drawbacks to the personalized healthcare services. Although smartphones acts as small and light-weight portable computers, smartphones have some limitations of computing power and storage spaces. Moreover, the loss or disclosure of private information could occur when a smartphone is changed or lost. So it is natural to come up with a system that lifelog data are sent to a stable and powerful server and the server utilizes the data efficiently and effectively. Since the system handles very sensitive personal information with unstable network wireless connections, an elaborate design of upstreaming system is required. This paper introduces the personal lifelog upstreaming system, called PLUS, that ensures us to transfer lifelog data in a smartphone to a stable server in a secure and reliable way. We also present the details of upstreaming protocol that shows how PLUS ensures the security and reliability during lifelog transmission. Finally we briefly introduce D-PLUS, an extension of PLUS that has a high availability and fault tolerance by dividing the tasks into several servers.
