Abstract
Abstract Apparatus for identifying wireless subscriber units and for granting or denying access to a subscriber service includes a plurality of wireless subscriber units each for generating a wireless subscriber signal including internal data traits and external signal traits. The internal data traits include an identification code. The plurality of wireless subscriber units also receive a transmitter/receiver signal. A receiver/transmitter is located remote from the wireless subscriber units and receives the wireless subscriber signal and transmits the transmitter/receiver signal. A characterizing device is connected to the receiver/transmitter and generates a plurality of characterizing signals for one of said wireless subscriber units. The characterizing device generates said plurality of characterizing signals by measuring features of said external traits of said one of said wireless subscriber signal from at least one of a first category including variations of specified parameters of said one of said wireless subscriber units, a second category including variations in non specified parameters, and a third category including variations in reactions or responses to interrogations. A converter connected to the characterizing device converts the plurality of characterizing signals into a security pattern. The security pattern and the identification code are used to identify said one of said wireless subscriber units. A historic security pattern storing device stores historic security patterns for said wireless subscriber units. A comparing device connected to the converter and the historic security pattern storing device compares the security pattern to the historic security pattern corresponding to said one of said wireless subscribers and generates a confidence level indicating a likelihood that one of said wireless subscriber units also generated the historic security pattern. An access device grants or denies access to the subscriber service based upon the confidence level.
