Abstract
The present invention relates to a method of ensuring integrity when transmitting data from a transmitting device to a receiving device, wherein said method comprises the step of adding a token to said data before transmitting said data. Thereby, by comparing transmitter tokens, the receiver can cancel out unwanted multiple copies of the same message originating from the same transmitting device. This can be performed without the sender knowing the real identity of the user operating the transmitting device. The token could e.g. be a random number, and if the chosen random number interval is large, the probability for other transmitting devices to create the same number is minimized.
