Policy-Driven Negotiations and Explanations: Exploiting Logic-Programming for Trust Management, Privacy & Security
Traditional protection mechanisms rely on the characterization of requesters by identity. This is adequate in a closed system with a known set of users but it is not feasible in open environments such as the Web, where parties may get in touch without being previously known to each other. In such cases policy-driven negotiation protocols have emerged as a possible solution to enforce security on future web applications. Along with this setting, we illustrate Protune, a system for specifying and cooperatively enforcing security and privacy policies (as well as other kinds of policies). Protune relies on logic programming for representing policies and for reasoning with and about them.
