Step A2: the cloud traffic management server takes the first cloud digital abstract, the vehicle identification code and the first cloud digital signature as parameters to generate a digital watermark, and then embeds the digital watermark into a common vehicle license plate image by combining the digital watermark key to generate the safe vehicle license plate image;
step A3: and generating a safety vehicle license plate according to the safety vehicle license plate image.
The invention has the beneficial effects that:
first, the invention embeds digital watermark information in the vehicle license plate image to generate a safe vehicle license plate, wherein the digital watermark information comprises abstract information of a common vehicle license plate image, a vehicle identification code corresponding to the vehicle license plate when the vehicle license plate is registered in a vehicle management department and signature information after the digital abstract and the vehicle identification code are digitally signed by a cloud traffic management server. By verifying the abstract information of the vehicle license plate image and the signature information of the vehicle identification code, whether the image content of the safe vehicle license plate is complete or not and whether the image content of the safe vehicle license plate is tampered or not can be determined, and whether the safe vehicle license plate is issued by the cloud management server or not can be determined. The problem of harm such as fake license plates and the like caused by illegal altering, tampering and/or imitation of the vehicle license plate image is solved from the source, and once the safety vehicle license plate image is illegally altered, tampered and/or imitated, the illegal operations can be verified;
Secondly, the invention compares the vehicle identification code information contained in the digital watermark with the vehicle identification code information which is built in a manufacturer and can only be read by a vehicle user when the vehicle leaves the factory, thereby determining whether the vehicle license plate is a fake-licensed vehicle or not;
thirdly, when the verification result of the vehicle license plate identification verification or the comparison result of the vehicle identification code information is problematic, the vehicle management part can be timely informed of whether the integrity of the safety vehicle license plate is damaged, tampered and forged or not and/or whether the fake license plate behavior of the vehicle license plate is verified;
fourth, when the collection end and the cloud traffic management server communicate with each other, signature and verification are carried out on communication information of the two parties, so that the integrity of the information and the authenticity of the identity of the sender in the communication process of the two parties are ensured.
