All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In order that the above-recited objects, features and advantages of the present application will become more readily apparent, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description.
Fig. 1 is a schematic diagram of a block chain-based interface trace-back system according to an embodiment of the present application, which mainly includes a requirement information analysis unit, a requirement information verification unit, a data format unit and a response data unit.
Specifically, the requirement information analysis unit, the requirement information verification unit, the data format unit and the response data unit are all located at the data response end. The data response end is coupled to the data request end and both are coupled to the blockchain as shown in fig. 2.
The request information analysis unit is used for receiving request data information sent by the data request end and obtaining request data verification information stored on the blockchain according to the request data information. The demand information verification unit is used for carrying out data request verification on the request data information and the request data verification information, and generating interface qualification when the data request verification passes. The data format unit is used for receiving the request data information according to the interface qualification and generating formatted data according to the request data information. The response data unit is used for sending the formatted data to the data request terminal according to the interface qualification and the request data information, generating response data verification information at the same time, and sending and storing the response data verification information to the blockchain.
Next, the structural composition and functional implementation of each device section will be specifically described in connection with the present embodiment.
In this embodiment, the request data information sent by the data request end mainly includes a request data number, request data information, request interface information, and request format information, and request end address information of the data request end. The information is sent to the data response end through the internet and is also sent to the blockchain and stored in the blockchain, and the information is called request data verification information. The two information contents are completely consistent, wherein the request data information sent through the Internet is mainly used for providing corresponding data by a data response end, and the request data verification information stored on the blockchain is mainly used for providing later requirement information verification.
After receiving the request data information sent by the data request end through the Internet, the data response end does not directly prepare and send the response data, but performs verification of the data response end, including verification of the request information by the demand information analysis unit and verification of the specific demand information by the demand information verification unit.
First, verification of the request information by the request information analysis unit is introduced.
After receiving the request data information sent by the data request end through the Internet, the request information analysis unit firstly inquires corresponding request data verification information in the blockchain according to the request data number in the request data information so as to judge whether the data request really exists.
When the same request data number is found, the request data information and other request data information, the request interface information, the request format information and the request end address information in the corresponding request data verification information are checked, if all the information is consistent, the request data information is confirmed to be a real data request, and the request data verification information is downloaded and acquired. If the individual information is inconsistent, the data request is considered to be unreal, and the data response end sends the returned information with wrong request to the data request end through the demand information analysis unit.
After the request data information sent by the data request end is confirmed to be a real data request, the demand information verification unit of the data response end verifies the specific demand information.
In this embodiment, the data request checks include a demand data check, a demand interface check, and a demand format check. Accordingly, the requirement information verification unit includes a requirement data verification subunit, a requirement interface verification subunit, and a requirement format verification subunit.
The demand data checking subunit is used for carrying out demand data checking, checking whether the content is the data demand provided by the data request terminal or not, and if not, sending return information which cannot be provided by the data to the data request terminal through the demand information analysis unit. If so, the demand interface test is continued.
The demand interface checking subunit is used for carrying out demand interface checking, checking whether an interface which is provided by the data request end and used for data transmission can be authorized to be used or not, and if the interface can not be used, sending return information which can not be provided by the interface to the data request end through the demand information analyzing unit. If the interface is available, generating interface qualification and carrying out requirement format check.
The demand format checking subunit is used for performing demand format checking, and checking whether the data request with the content set by the data request end and the data response end can be provided.
If all the three items can be met, the data format unit receives the request data information according to the interface qualification and generates formatted data according to the request data information.
Specifically, the data format unit includes an interface subunit, a data subunit, and a formatting unit.
The interface subunit opens the corresponding data interface according to the interface qualification, so that the request data information and the subsequent formatted data can pass through. Then, the data subunit receives the request data information through the data interface, and acquires the corresponding data, called response data, from the database according to the request data information. And finally, the formatting unit performs formatting processing on the response data according to the required format information in the request data information, generates formatted data, namely data content corresponding to the request data information sent by the data request end, and sends the formatted data to the data request end by the response data unit.
In this embodiment, the response data unit is composed of a data transmission subunit and an information backup subunit.
Specifically, the data transmitting subunit transmits formatted data to the data request end through the data interface according to the interface qualification and the address information of the request end in the request data information.
The information backup subunit performs image processing on the formatted data and the request data information, generates response data verification information, and sends and stores the response data verification information to the blockchain. In this embodiment, the image processing refers to packaging processing of keywords in the formatted data and the request data information.
In the foregoing data request verification, there is also a case where the demand format verification fails, which means that the data responding end cannot provide the data format corresponding to the data requesting end. In this embodiment, the manner of solving the problem is to set an encryption subunit in the data format unit, encrypt the response data by using the encryption subunit, and generate encrypted data, so as to ensure the security in the data transmission process, and generate a response key for decrypting the data of the data request end.
At this time, the information backup sub-unit performs image processing on the encrypted data and the request data information, generates response data verification information, and transmits and stores the response data verification information and the response key to the blockchain. The data requesting end obtains the response key from the blockchain. In this embodiment, the response key is one-to-one with the corresponding encrypted data, that is, the encrypted data and the corresponding response key are obtained simultaneously, and the party can obtain the response data.
Further, in order to ensure that the data requirements of the data request end and the data provided by the data response end are consistent, a storage unit and a verification unit are arranged on the blockchain.
The storage unit is used for storing request data verification information and response data verification information.
The verification unit is used for carrying out demand consistency verification on the request data verification information and the response data verification information, and when the demand consistency verification is passed, the verification unit sends verification passing information to the data request terminal, and the verification passing information indicates that the data request is consistent with the response. When the demand consistency test fails, the verification unit sends response error information to the data request terminal, and the data request terminal needs to send request data information to the data response terminal again.
The above embodiments are merely illustrative of the preferred embodiments of the present application, and the scope of the present application is not limited thereto, but various modifications and improvements made by those skilled in the art to which the present application pertains are made without departing from the spirit of the present application, and all modifications and improvements fall within the scope of the present application as defined in the appended claims.
