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.
