A Survey Study of Life Log and a Proposal of Record-Prevention Method

The Life Log records computer use, details of mobile device use and sensor values collected from user's activities. Data recorded in life log is analyzed by the cloud computing and turned into useful information. Many researches to provide useful services to human beings making use of the useful information have been widely conducted. This paper surveys life log and proposes a record-preventing method and a device that is facilitated with the record-preventing function. The proposed system consists of the input component, the control component, and the output component. The input component reads data from the GPS receiver, the RFID (Radio-Frequency Identification) reader, the QR code (Quick Response Code) reader, a camera, and sensors. The control component compares the input data with the data stored in the database in order to determine whether the user is within a forbidden area. The control component stops life-logging if the user is within a forbidden area.
