Protecting privacy while sharing information in electronic communities

A great deal of economically useful information is distributed among many people. Collecting and utilizing this information could potentially provide many useful services not only for the people from whom the information is obtained but also others with similar interests. For instance, recommendation systems rely on feedback about the quality or suitability of various items from those who have used them in the past. As another example, the development of reputations through dealing with a number of people can help future transactions with new people by establishing well-regarded brand names. Reputations are extremely valuable in the context of electronic commerce, for they provide a mechanism to establish trust and reduce the costs and risks involved in transactions.
