Recent drastic advances on the mobile technologies and the network infrastructure have enabled kinds of new cyber spatial services to substitute for the various existing offline activities. The Social Network Services can be considered the most conspicuous one of these services and it has been propagating day by day in virtue of the expansion of the mobile internet devices. Even though this type of services is getting prevalent in our society, lack of assurance on the privacy and trust management has been highly worried among cautious users. The messages are released imminently and intuitively in these services, especially on the mobile devices, and the opinions and interactions may be imprecise or imprudent. This makes people get difficulties to give trust to the posts published on the social network services. At the beginning of the era of the mobile computing environment, it seems to be most important to achieve assurance with the management of Trust and Privacy if we desire to keep our another-society clean, transparent and reliable. This special issue focuses on recent advances and significant contributions to the Trust Management.
