Abstract

The invention is a method of making a mobile telephone more secure and includes generating an identification code, inserting the code into transmitted speech, detecting the code at a base station and comparing it with stored information to verify the authenticity of the mobile telephone. The identification code comprises two portions: the first portion (which stores the code) being produced during manufacture of a chip and the second portion being formed by a randomised process during commissioning of the telephone. The invention overcomes problems associated with similar, prior art systems because the chip containing the identification code has part of its code randomly selected because it is an irreversible process.
