Computer-implemented method for managing user-submitted reviews using anonymous reputation system

A computer-implemented method for managing user-submitted reviews of items of goods or services, comprising:

• maintaining an anonymous reputation system constructed from a group of group signature schemes run in parallel, wherein:
• each item of a plurality of items of goods or services is associated uniquely with one of the group signature schemes;
• the anonymous reputation system allows a user to join the group signature scheme associated with the item when the anonymous reputation system receives information indicating that the user has performed a predetermined operation associated with the item;
• the anonymous reputation system allows the user to submit a review of the item when the user has joined the group signature scheme associated with the item;
• the anonymous reputation system is publicly linkable, such that where multiple reviews are submitted by the same user for the same item, the reviews are publicly linked to indicate that the reviews originate from the same user;
• and
• the anonymous reputation system is configured to be non-frameable, wherein non-frameability is defined as requiring that it is unfeasible for one user to generate a valid review that traces or links to a different user.
