Conference Title: 2016 14th Annual Conference on Privacy, Security and Trust (PST) Conference Start Date: 2016, Dec. 12 Conference End Date: 2016, Dec. 14 Conference Location: Auckland, New Zealand Trust is an important concept in human relationships. However, trust yields a false sense of security as trust leads to decreased vigilance towards a threat. Cases related to fraudulent activities and life-threatening incidents highlight the importance and necessity of peers trust re-evaluation. Trust re-evaluation has been studied over the last decade, yet none of the approaches targets the physiological measurements of a trustee nor does any provide the trustor a system to detect the intentions of a trustee when providing/requesting information. In this paper, we present the design of a trust re-evaluation system (TrustMe) that provides the trustor with the risk levels when trusting a trustee. TrustMe is a cloud-based service that detects the intention and motivation levels behind the information a trustee provides using the intent and motivation detection components of the Intent-based Access Control (IBAC) model. A trustor is provided the risk of trusting a trustee; hence, a trustor can make informed decisions whether to trust the trustee and accept the provided information. Further, a certificate of good intention is granted to a trustee to present to a trustor if the risk levels are determined to be lower than a pre-determined threshold set by the trustor. The current design of TrustMe assesses risk in decisions that involve personal and financial matters.
