摘要: A method for testing the authenticity of data carriers having integrated circuits, memory and logic means to determine physical properties each circuit that are distinctive this use them obtain characteristic circuit. According present invention, one preferably evaluates different programming times cells an E2 PROM memory, evaluation which can be determined by various methods processed as characteristics. Other individual utilized are, example, features a input.
