Project Description

Trust and reputation systems, which in their simplest form allow users to provide a “star” rating to a service provider, have seen widespread use on the internet. Computer scientists have designed complex trust systems aimed at resisting different types of attacks (such as collusion between raters). To date, the evaluation of such systems has been mostly empirical. This project will investigate general properties of trust and reputation frameworks using a formal setting. The aim is to provide both desiderata for trust system properties, and proofs regarding whether specific trust systems do, or do not, meet these properties.

One approach to proving these properties comes from the field of dynamic networks, where the system is modelled through difference (or differential) equations, and properties proved based on the properties of these equations. To this end, the proposed studentship will be supervised by members of both the Computing Science and Physics departments.

The successful applicant should have, or expect to have, an Honours Degree at 2.1 or above (or equivalent) in A mathematical discipline (e.g. Mathematics, physics or economics).

Funding Notes

There is no funding attached to this project, it is for self-funded students only.
