Towards a Reputation System for the Internet

Ian Wakeman

University of Sussex

As the Internet becomes an increasingly complex web of applications and data, a major challenge will be in reducing the required management intervention from both users and network administrators. One of the recurring management decisions we would like to automate is when one system has to decide how to interact with another system. Should it trust the other system? If it is charging for the interaction, how much should it charge?

We believe that predefining which systems and what interactions are allowed will be too rigid for some systems and their possible interactions. Instead the decision should be based on the past history of the systems with each other and other systems. To this end we are designing and building a reputation system, where the history of past interactions is used to provide measures of the reputation of entities.

In this talk, I will discuss the challenges in building such a reputation system, and our progress to date.
