Online dating is one domain, which would benefit from the application of computational trust. One of the problems with the application of traditional computational trust models, as identified in our previous work, is authenticity of information provided by parties which helps other users ascertain whether they want to go on dates. In this position paper, we suggest a solution: a concordance based...
Users are able to arbitrarily make assertions about themselves online. In many spaces, it is valuable to both the users and information consumers that those statements can be validated and trusted. In this paper, we present the Publish Trust Framework. This leverages Semantic Web technologies to add provenance to the attributes a person wants to assert about themselves. That connects the statements...
This work provides a game theoretic framework through which one can study the different trust and mitigation strategies a decision maker can employ when soliciting advice or input from a potentially self-interested third-party. The framework supports a single decision maker's interacting with an arbitrary number of either honest or malicious (and malicious in varying ways) advisors. We include some...
Web sites usually express their privacy practices in natural language text that is often complex, informal and possibly confusing. The platform for Privacy Preference (P3P) has been proposed by W3C as a technology for expressing privacy practices of web sites in precise, machine readable language. This paper provides an account of the current status of research on P3P and proposes directions for future...
This paper describes a data collection distributed platform composed of various high interaction honeypots deployed in different locations, along with our first analyses of this data. This deployment follows a previous experiment conducted with the same honeypot that was deployed at a single location (cf. [1]). The objective is to check if the results of our first experiment can be generalized.
Traditional security technologies are based on numerous assumptions about the environment in which systems are used. This includes assumptions about the enforcement of legislative and contractual frameworks, limitations of particular technologies and the constraints on human behaviour imposed by social and religious norms. Most of these assumptions, however, are implicit and they will fail when the...
