Abstract: A method, system, and computer-readable medium for assisting in targeting information to users while protecting the privacy of those users is described. Various transaction and/or other user-specific information may first be obtained from one or more of a variety of information sources, and can then be provided to user targeters that desire to target information to other users that match specified criteria. Information about the matching users is provided to the user targeters in a manner that obscures the identity of those users. After a user targeter selects identity-obscured users to which targeted information is to be provided, the information is provided to those targeted users in various ways. In some situations, the targeted information is marketing information such as an advertisement and/or information about a discount or other promotional benefit that is available, and is provided to users at a POS location.
