Abstract—While personal data privacy is threatened by online
social networks, researchers are seeking for privacy protection
tools and methods to assist online social network providers
and users. In this paper, we aim to address this problem by
investigating how to quantitatively evaluate the privacy risk, as
a function of people’s awareness of privacy risks as well as
whether their friends can be trusted to protect their personal
data. We present a trust-aware privacy evaluation framework,
called TAPE. Simulations are performed to illustrate the key
concepts and calculations in TAPE, as well as demonstrate the
advantages of TAPE.
