With the development of social network such as microblog, the number of microblog users increases rapidly. The problem of information overload caused by a large amount of data generated by users is becoming more and more serious. In order to mine the messages which specific users are interested in, we measure social relationship and interactive relationship of users respectively in this paper a...

Zhong et al. formulated the problem of disclosing credentials (associated with privacy) for building trust in an open environment like Internet. Thus, one form of privacy-trust problem is formulated in [17]. In [17], an entropy measure is defined to quantify privacy loss. In this research paper, by a proper formulation (modelling), the privacy-trust tradeoff is attacked from the Information The...

An evaluating mechanism-based cloud computing trust model is raised to aim at the issue of how the cloud service user selects credible cloud service supplier. The trust model constitutes an evaluating system about service behavior between cloud service supplier and cloud service user. After formalized evaluation about entity achieved, certain algorithm would be used to get the trust and trust v...

An important challenge regarding peer’s trust valuation in peer-to-peer (P2P) networks is how to cope with such problems as dishonest feedbacks of malicious peers and collusions, which cannot be effectively tackled by the existing solutions. So a feedback confidence (FC)-based distributed trust management scheme for P2P networks, named FCTM for short, is proposed to quantify and evaluate the tr...

We describe preliminary research that attempts to quantify the level of trust that exists in typical interactions between human users and their computer systems. We describe the cognitive and emotional states that are correlated to trust, and we present preliminary experiments using functional near infrared spectroscopy (fNIRS) and electroencephalography (EEG) to measure these user states. Our ...
