Abstract: A trust policy is constructed based upon a social relationship between real-world entities. The trust policy may determined based upon a social network and social network maps. The social network map provides a framework to determine social distances. The trust policy provides quick and secure access to desired or trusted nodes while providing security from entities outside the trusted sphere of nodes. The trust policy determined by the social distance may be used for various types of applications including filtering unwanted e-mail, providing secure access to resources, and accessing protected services. File sharing, referral querying, advertisement targeting, announcement targeting, access control, and various applications may be limited using the constructed trust policy.
