Wherein the intelligent contract is stored on the block chain, and the intelligent contract is equivalent to a digital contract which can execute the code on the CPU. The intelligent contract may be defined, and the intelligent contract may be generated according to a use condition of the vehicle diagnostic data, wherein the use condition of the vehicle diagnostic data may be set according to the right of ownership of the vehicle diagnostic data. Further, the intelligent contracts are registered in the blockchain and broadcast to the various nodes of the blockchain. Since each node of the block chain has no authority to modify the intelligent contract, the normalization of the intelligent contract is ensured.
Step S306: a data usage request of a user is received.
Step S306 is the same as step S105, and is not described herein again.
Step S307: and judging whether the data use request is legal or not.
Specifically, the step of determining whether the data use request is legal includes the following steps:
step S401: keywords input by a user are received.
The user can be a vehicle owner, a vehicle enterprise and other types of users. For example, when the user is an owner of a vehicle, the owner of the vehicle may enter keywords related to the performance of the vehicle. After the user inputs the keywords, the keywords input by the user are received.
Step S402: and judging whether a data index matched with the keyword exists or not based on the keyword.
For example, if the user aims to inquire the mileage of a car and inputs "mileage is within 10 KM", it is determined whether an index matching the keyword exists in the block chain based on "mileage is within 10 KM".
Step S403: and if the data index matched with the keyword exists, judging whether the transaction commitment in the data use request meets the intelligent contract.
The keywords and the index may be in a one-to-one relationship or a one-to-many relationship. It is not assumed that index a, index B, and index C are queried based on "mileage within 10KM," and obviously there is an index matching the keyword, and it is determined whether the transaction commitment in the data usage request satisfies the smart contract.
Illustratively, determining whether the transaction commitment in the data usage request satisfies the smart contract comprises:
determining whether the user has paid a predetermined fee; and if the user pays a preset fee, determining that the user meets the condition of the intelligent contract.
Step S404: and if the intelligent contract is met, determining that the data use request is legal.
For example, when the owner of the vehicle wants to inquire about the relevant diagnostic data, the owner pays a predetermined fee to obtain the right to view, i.e., to satisfy the intelligent contract. If the owner does not pay the predetermined fee, the intelligent contract is not satisfied, and the system returns the word 'not satisfied'. The predetermined fee may be set in advance in the smart contract. It will be appreciated that the user need not pay when viewing his own authorized diagnostic report.
Step S308: and sending the corresponding diagnosis data to the user according to the type of the user.
Step S308 is the same as step S106, and is not described herein again.
In this embodiment, whether an index matched with a keyword exists in a block chain is judged by receiving the keyword input by a user, whether a transaction commitment in the data use request meets an intelligent contract is further judged, if yes, corresponding diagnostic data is sent to the user according to the type of the user, and normalization of an acquisition condition of the diagnostic data is ensured, so that safety of the diagnostic data is ensured.
