Single use user IDS

摘要

An access verifier may act as an intermediary to allow users to receive single use user IDs while protecting their anonymity. The access verifier has some relationship with the user that allows the access verifier to know details regarding the user that might be helpful in determining whether the user is a potentially desirable customer. The user may request a user ID from the access verifier. The user may then pass the user ID to the access provider when the user wishes to gain access. Upon receiving the user ID, the access provider may request verification that the ID is valid from the access verifier. The access verifier may respond that the ID is valid (if appropriate), and also may include user information. The access provider is thereby provided with some level of assurance that the user is a potential customer without knowing confidential information.
