(An) IoT trust value estimation scheme leveraging interaction history of friends sharing a common experience

Abstract

Existing trust management is a method of calculating the trust value by providing information on the sociality or past experiences of IoT devices, or it calculates the trust value using the experience related to the target device of the user. In the former case, it is impossible to compute the trust value when the user first visits the site. In the latter case, it is the direct experience of the user. However, since the experience using the same device type Do not use the information to calculate the trust value. In this paper, we propose trust management using the opinions of friends in Social Network Service, personal trust using the personal experience of the user, and stereotypical trust value related to place at the location where the user first visited. Because of the lack of direct information about the area, we use opinions from users and similar friends on the social network service.
