Abstract: An automated network access protection system providing an efficient method for creating a list of disallowed network connection points. This is done by collecting network addresses connected to by users who have accessed the network in an unauthorized manner. This list of addresses is filtered to eliminate addresses which have been connected to by users not known to be unauthorized. Once this filtering has been completed, the list contains network addresses or phone numbers connected to only by unauthorized users. This list may further be filtered by removing any network addresses which appear in a separate list of globally valid addresses. This list may also be filtered to eliminate network addresses which are owned by commercial entities. Finally, custom filters may be applied to this list. After this filtering, this list is transferred to a mechanism for preventing connection to or from any of the network addresses or phone numbers contained in the disallowed list.

Abstract: A cellular phone identity protection system that protects the identities of cellular telephones as they initiate calls through a cellular telephone system. The identity protection is provided through the use of jamming techniques and intentional false and tagged identity transmissions designed to prevent criminals from receiving valid subscribers' mobile identities over the airwaves. Jamming transmissions are made on the same frequency as the mobile transmissions, overpowering the valid mobile signals at the criminals' receivers, thereby preventing the criminals' equipment from properly decoding the MIN, ESN, SCM and other valid data transmitted by the valid mobile unit. These same jamming transmissions are fed, 180 degrees out of phase and level adjusted, into the receive antenna lines of the cell site control channel, canceling the effects of the jamming at the cell site receivers thereby allowing valid mobile call attempts to be processed normally.
