[0030] Figure 1 A flow chart of a method provided by an embodiment of the present invention is shown.

[0031] Specifically, the Internet of Vehicles data sharing method based on blockchain includes the following steps: Step S101, receiving target road condition data sent by a first intelligent vehicle, and performing initialization recognition on the target road condition data to generate an initialization recognition result.

[0032] In an embodiment of the present invention, multiple smart vehicles can report abnormal road conditions during driving automatically or according to the driver's requirements. By receiving the target road condition data sent by the first smart vehicle, a driving record instruction is generated, and then the driving record instruction is sent to the first smart vehicle. After receiving the driving record instruction, the first smart vehicle can feedback and transmit the driving record data. By receiving the driving record data fed back by the first smart vehicle, the target road condition data is initialized and identified based on the driving record data, and an initialization identification result is generated to achieve authenticity identification of the target road condition data.

At the same time, the power operation enhances the nonlinear representation capability and can better capture complex data relationships. Finally, by introducing multiple weight matrices and bias vectors, the model parameters can be adjusted in multiple directions to improve the robustness of the results. Furthermore, the blockchain-based Internet of Vehicles data sharing method further includes the following steps: Step S104, performing road condition verification analysis on the verification feedback data to determine whether the verification is passed.

The location verification result and the road condition verification result are combined to determine whether the verification is passed, thereby achieving accuracy verification. Specifically: only when both the location verification and the road condition verification are passed, can it be determined that the verification is passed.

[0046] Specifically, Figure 5 A flow chart of road condition verification, analysis and judgment in the method provided by an embodiment of the present invention is shown.
