Abstract: A method for tracking and controlling privacy information within a lead sales system includes logging receipt in a log of one or more encrypted leads by a trusted privacy information manager (TPIM) that are received from a participant thereof, the one or more leads including private lead information from a lead provider having been pre-processed and encrypted with a one-way hash algorithm; comparing the received one or more encrypted leads with stored encrypted leads to find matches; updating the log related to the one or more encrypted leads with information associated with the matching one or more encrypted leads, the log information including at least one of an e-mail address and a phone number of the lead provider; and communicating to the lead provider at least one way to access a user interface of the TPIM that enables the lead provider to control his or her private lead information.
