A method for validating a road traffic control transaction including recording an image of a vehicle, reading a vehicle identification in the recorded image by means of OCR and generating a control transaction thereof; generating a random key and encrypting the recorded image into authentication data with the random key and a cryptographic key of a transaction receiver in a separate processing element of a control station; sending the recorded image, the control transaction , the random key and the authentication data to the transaction receiver; in the transaction receiver: encrypting the recorded image into nominal authentication data with the received random key and the cryptographic key and comparing the received authentication data with the nominal authentication data, wherein the control transaction is validated if the two datasets are identical. |
