In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
In addition, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present invention. It will be understood by those skilled in the art that the present invention may be practiced without some of these specific details. In some instances, well known means have not been described in detail so as not to obscure the present invention.
An embodiment of the present invention provides a vehicle anti-theft method, which can be applied to vehicle anti-theft of cars, shared bicycles, and the like, where fig. 1 is a flowchart of the method in this embodiment, and referring to fig. 1, the method in this embodiment includes steps S101 to S103:
s101, acquiring a dynamic characteristic graph of a mobile terminal by vehicle-mounted equipment, performing characteristic analysis on the dynamic characteristic graph to obtain secondary dynamic verification data, and calculating according to the secondary dynamic verification data and a preset first algorithm to obtain a first calculation result; the dynamic characteristic graph is generated by the mobile terminal according to primary dynamic verification data provided by the server and a preset second algorithm, and the primary dynamic verification data is generated by the server according to verification request information sent by the mobile terminal and a preset third algorithm;
specifically, the vehicle-mounted device is a device mounted on a vehicle, and is capable of executing the process of steps S101 to S103, and the mobile terminal is, for example, a mobile phone, a tablet computer, a smart watch, or the like.
It can be understood that any encryption algorithm can be selected for the preset first algorithm, the preset second algorithm and the preset third algorithm, so that a unique encryption value can be obtained in the calculation process, and the data consistency verification can be performed after the multi-terminal calculation conversion, which is not specifically limited in this embodiment.
For example, the authentication request information is the identity of the current user, such as a registered user, the identity of which is already authenticated and confirmed, and only the real and valid user can send a request, and the authentication request belongs to the user applying for the use permission from the server.
The server verifies the verification request information according to the mobile terminal, and generates primary dynamic verification data by using a preset third algorithm under the condition that the verification is passed, wherein it needs to be noted that the generation of the primary dynamic verification data is random so as to improve the reliability of theft prevention.
It can be understood that the APP on the mobile terminal and the server have a dedicated network interface, and the user applies for the server through an account number (for example, a binding mobile phone number, an identity card, and the like to determine that the user is a real and valid user) that has been successfully registered on the APP. The verification method comprises two verification steps, wherein the first verification step is that the mobile terminal APP can send verification request information only through an existing account, and the second verification step is that the server verifies and confirms the verification request information uploaded by the mobile terminal APP.
The information stored in the dynamic characteristic graph at least comprises identification generation time, effective time and data content corresponding to one-time dynamic verification data, the data content is stored in a data storage area of the graph, a timestamp is stored in a timestamp storage area of the graph, and the dynamic characteristic graph can be a two-dimensional code graph.
The step of performing feature analysis on the dynamic feature graph to obtain secondary dynamic verification data specifically comprises: and judging the specification and the timestamp of the dynamic feature pattern, wherein the timestamp comprises identification generation time and valid time, if the specification of the dynamic feature pattern does not meet the preset requirement, or the identification generation time and the valid time of the pattern do not meet the time requirement, for example, the identification generation time and the valid time exceed the valid time, the dynamic feature pattern is judged to be an invalid pattern, and if the specification of the dynamic feature pattern meets the preset requirement, image features are further extracted to obtain secondary dynamic verification data. For example, in dynamic changes, since the effective time of the timestamp storage area changes, and the decoding method also changes, the corresponding verification data also follows the synchronous change of the storage area. When the equipment scans the dynamic feature pattern, after the timestamp is confirmed to be normal, the decoding mode is obtained, the features are extracted in different areas according to the current decoding mode, and the verification data is analyzed.
Step S102, the vehicle-mounted equipment sends the first calculation result to a server;
step S103, the vehicle-mounted equipment receives a verification result sent by the server and releases the vehicle anti-theft system according to the verification result; and the verification result is a matching result obtained by the server generating a second calculation result according to the primary dynamic verification data and a preset first algorithm and matching the first calculation result with the second calculation result.

The dynamic characteristic graph of the mobile terminal held by the user is identified through the vehicle-mounted equipment, the dynamic characteristic graph is used as a use certificate for removing the vehicle anti-theft system, and compared with a currently used physical key or a currently used virtual Bluetooth key, the flexibility and the convenience for removing the vehicle anti-theft system can be improved. And the dynamic characteristic graph is generated by the mobile terminal, and a user only needs to interact with the background server through the mobile terminal, so that the condition that the handheld terminal enters an illegal website to cause cheating or virus implantation is avoided.
In a specific embodiment, the step of generating the dynamic feature pattern by the mobile terminal according to the primary dynamic verification data provided by the server and the preset second algorithm specifically includes the following steps S201 to S204:

In a specific embodiment, the method further comprises:
when the server matches the first calculation result with the second calculation result to obtain a matching result that the first calculation result is consistent with the second calculation result, the server binds the user information with relevant information (vehicle information or vehicle-mounted device information) of the vehicle-mounted device sending the first calculation result, and sends the verification result to the vehicle-mounted device and the mobile terminal; wherein the authentication request information at least comprises user information (for example, account information registered by the user through the APP);
