In specific implementation, the terminal 501 may respectively send the first hash value and the second hash value to the vehicle management station node server 502 according to a predetermined sequence of annual inspection time of the vehicle or a predetermined sequence of purchasing years of the vehicle.
Wherein the first stored information is information of a first vehicle M stored in advance, and the second stored information is information of a second vehicle N stored in advance;
it should be noted that after the license plate numbers of the first vehicle M and the second vehicle N are interchanged, the specific information of the two vehicles is as follows: the license plate number of the first vehicle M is jing DEF123, the engine number of the first vehicle M remains unchanged, the annual inspection time validity period of the second vehicle M is 2020, 5 and 31, the license plate number of the second vehicle N is jing ABC666, the engine number of the second vehicle N remains unchanged, and the annual inspection time validity period of the second vehicle N is 2021, 2 and 28.
The second broadcast message comprises a block chain identifier of the terminal, identity information of a user to which the terminal belongs, a first hash value, a second hash value, an updated license plate number of the first vehicle and an updated license plate number of the second vehicle.
