Abstract

Digital Diorama, the sensing-based real-world content, can be constructed by integrating real-time information obtained from sensors monitoring the real world. In order to increase the benefits of viewers without violating the privacy of monitored persons, this paper proposes three-level privacy control over the monitored persons based on their agreement to the usage of their information obtained from sensors: privacy control with i) no agreement, ii) partial agreement. and iii) mutual agreement. i) presents only their positions to show where persons are. ii) additionally presents the information which can be automatically obtained from sensors such as age and gender to show what kinds of persons are where without disclosing the visual appearances. iii) presents their visual appearances based on their mutual agreement with specific viewers. Our evaluation indicated that the representation simulating each privacy control presented information from sensors with acceptable privacy protection.
