Embodiment Construction
[0012] Such as figure 1 As shown, the electronic license plate circuit part includes a display screen 3 , an intelligent control circuit 2 and a power supply circuit 1 . The display screen 3 is used to display the two-dimensional code, the intelligent control circuit 2 is used to control the time-based generation of the two-dimensional code, the power supply circuit 1 includes a built-in battery, and has a connection device with the internal battery of the locomotive as a power supplement.
[0013] figure 2 It is a schematic diagram of the encryption process of the electronic license plate. You can choose the AES algorithm as the encryption algorithm, and use the 16-byte ASCII string as the identification code, corresponding to a 128-bit binary code, as the identification code plaintext 8. When every minute is selected as the change interval, corresponding to the time value per minute, we have a 16-byte time value, such as "2015‐01‐03 21:23", and the time value is expressed ...

The invention provides a program control variable two-dimension code-based anti-counterfeiting license plate and an application method of the program control variable two-dimension code-based anti-counterfeiting license plate. The license plate is composed of a license plate number printing part and a two-dimension code display screen part controlled by an intelligent circuit. The display screen is made of an electronic ink screen, an LCD screen or an LED screen. Firstly, an identification code is set for each registered vehicle by the vehicle management department, the identification code is only stored in a server of the vehicle management department and an intelligent circuit chip of an electronic license plate, secret keys corresponding to time are generated by the intelligent circuit chip at a fixed time interval in specific rules according to the time variation, the identification code of the vehicle is encrypted through the secret keys, cryptograph is displayed on the display screen of the license plate in the form of two-dimension code, the image is sent to the server of the vehicle management department after a special surveillance camera on the road or a camera held by a policeman takes a picture of the vehicle, decryption is carried out by the identical secret keys, and comparison with the identification code of the vehicle registered in the server is then carried out, so that authenticity of the license plate can be known.
Description
technical field [0001] The invention relates to an anti-counterfeiting license plate, which uses electronic intelligence technology to realize anti-counterfeiting and anti-theft of the license plate, and is applied in the field of vehicle management. Background technique [0002] Vehicle license plates seriously endanger the country's economic order and social stability. Therefore, cracking down on plate license plates has become an important task for the motor vehicle management department. There are many license plate anti-counterfeiting technologies, such as laser anti-counterfeiting and watermark anti-counterfeiting, but their characteristics are all displayed through visual effects. Because they are visible, they can also be imitated by high-tech means. In addition, even if anti-counterfeiting technology is added, when the license plate is stolen, it is still difficult to identify the stolen license plate through effective means. Contents of the invention [0003] In...
