Abstract: A method and apparatus for a non-revealing do-not-contact list system in which a do-not-contact list of one-way hashed consumer contact information is provided to a set of one or more entities. The set of entities determine whether certain consumers wish to be contacted with the do-not-contact list without discovering actual consumer contact information.

Abstract: A method and apparatus to protect a master do-not-email list from being compromised. A set of one or more false email addresses that each point to an email account that is not used for any email is created for a client and is unique to the client. An encryption scheme is applied to the set of false email addresses. The encrypted false email addresses for the client are recorded on the master do-not-email list, which also includes multiple encrypted real email addresses that each correspond to a real email address that point to an email account that is used for real email and does not wish to be contacted. A client do-not-email list is seeded for the client with the encrypted real email addresses and the encrypted false email addresses. The email accounts corresponding to the set of false email addresses are monitored for received email messages, where email messages received at one of the set of email accounts is an indication that the client should be investigated to determine potential liability.
Abstract: A computer implemented method comprising receiving a list of one or more contact points from a sender and comparing the list of one or more contact points to a satellite server's do-not-contact list. Any contact point on the list of one or more contact points that appears on the satellite server's do-not-contact list is reported to the sender. The satellite server's do-not-contact list is generated from a do-not-contact list distributed by a master server. A registrant registers with the master server to provide a registrant contact point to be on the do-not-contact list to be distributed by the master server. The contact points in the registry may be organized in a hierarchy with preferences at one or more levels.
