Abstract

A system and method to protect a target telephone number from unauthorized access includes a first one-way encoding unit to encode the target telephone number using nonreversible encoding. A storage unit stores the encoded target telephone number. A second one-way encoding unit encodes a calling telephone number and a receiving telephone number using the non-reversible encoding. A comparing unit determines whether the stored encoded target telephone number matches the encoded calling telephone number and/or the receiving telephone number and routing a call between the calling telephone number and the receiving telephone number matching the target telephone number to a monitoring unit. The monitoring unit monitors and/or records the call and connects the calling telephone number to the receiving telephone number.
