[0036] In the embodiment of the present invention, the meaning of on-chain storage is to store accurate evidence data in the blockchain network, and to store information on the chain in an encrypted manner to ensure the security of the information.

[0037] According to the precise information processing method of the embodiment of the present invention, the data information generated in the precise data processing process can be processed by data standardization, key data can be extracted and encrypted, and the precise evidence data formed after encryption can be obtained.

[0038] The precise information processing method of the embodiment of the present invention can standardize precise data notarization behavior, improve precise data management capabilities, and perform full life cycle management and reliable traceability of the entire process of precise data processing, thereby improving the data management level and supervision efficiency of data processing objects.

[0039] In some embodiments, the original data information includes at least one of stock data and incremental data generated during the precise data processing process; wherein the stock data information refers to the precise data saved by an existing precise data platform before a specified time node (such as the current moment); and the incremental data information refers to the precise data added to the existing precise data platform within a specified time period.

[0040] The specified time period may be set according to actual needs, for example, greater than or equal to 1 time unit, and the time unit may be an hour, a day, a month or a year.

The information digest algorithm and the hash algorithm can be selected according to actual needs, and the embodiment of the present invention does not specifically limit them.

[0043] In the embodiment of the present invention, the process of performing normalized data processing on the original data information can be understood as the process of extracting key data from the original data information; through this normalized data processing, accurate evidence data stored on the chain can be generated based on the extracted key data on the basis of the original accurate data, so that the evidence data stored on the chain can be standardized to improve the accurate data processing and management capabilities.

[0045] In the embodiment of the present invention, various original data information can be searched and / or accessed through accurate evidence data, and the original data in the original data platform can be searched and accessed under the premise of ensuring data security.

[0046] In some embodiments, the key data includes at least a storage account; the blockchain storage platform includes multiple storage chain nodes, and each storage chain node corresponds to a predetermined data processing participant.

[0047] In this embodiment, the step of storing the precise evidence data on the chain in step S130 may specifically include: S21, obtaining the evidence account from the key data; S22, determining the data processing participant corresponding to the evidence account based on the correspondence between the preset evidence account and the data processing participant; S23, storing the evidence data corresponding to the evidence account obtained from the precise evidence data in the evidence chain node of the corresponding data processing participant.

[0063] In this embodiment, multiple types of data access interfaces can be preset on the existing precise data platform. Users can access the existing precise data platform through different types of data access interfaces, and can access the data in the precise big data platform through the existing precise data platform, such as the key data in the original data information obtained after the precise data platform performs standardized data processing on the original data information; the data of the blockchain evidence platform can also be accessed through the existing precise data platform, such as the precise evidence data stored on the chain, so that the existing precise data platform can be connected with the precise big data platform (for accessing the key data extracted from the original data information) and with the blockchain evidence platform (for accessing the precise evidence data).

[0064] In some embodiments, when the precise evidence data on the blockchain evidence platform is accessed, corresponding data access evidence data is generated to record access behavior information and operation behavior information of the precise evidence data.

[0065] In this embodiment, when the data on the blockchain evidence storage platform is accessed, data access evidence data can be generated and stored in real time, so as to record the access and operation behavior of the on-chain data and improve the supervision ability of the data on the blockchain evidence storage platform.

[0066] According to the precise information processing method of the embodiment of the present invention, the data on the existing precise data platform can be transformed, and unified and standardized data processing can be performed. Based on the existing precise data, precise evidence data stored on the chain can be generated, thereby utilizing the characteristics of blockchain that cannot be tampered with, can be traced, and has high security, to ensure that the evidence data is not tampered with, improve the reliability and traceability of precise data, and thereby improve the level of precise data processing and supervision efficiency.

[0067] The step division of the above methods is only for the purpose of clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the scope of protection of this patent; adding insignificant modifications to the algorithm or process or introducing insignificant designs without changing the core design of the algorithm and process are all within the scope of protection of this patent.
