Problems solved by technology

However, the general blockchain distributed data storage method leads to great pressure on data storage and access. At the same time, in the application of government data, the sharing and use of data involves many departments, and the responsibilities and permissions of each department are complicated. The setting, classification, and change processing of user identities, access rights, etc. are cumbersome, which brings great difficulties to the security control and efficient use of data in the blockchain

Embodiment 1

[0130] This embodiment describes a method for storing government affairs data based on a blockchain double-chain structure from the side of the client, proxy server, ID card chain, and business data chain.

[0131] like figure 1 As shown, the government data storage method based on the block chain double chain structure of this embodiment specifically includes:

[0132] S101: The client uploads data to the proxy server.

[0133] In a specific implementation, the user (data provider) uploads the data to be stored to the proxy server through the client.

[0134] It should be noted that the data to be stored includes, but is not limited to, the clock-in and clock-out record data of all employees in each department within the corresponding time period, the progress data of related tasks in a specific department, and the like.

[0135] S102: The proxy server sends a data storage request to the identity chain, and verifies the user identity and the data storage request.

[0136] ...

Embodiment 2

[0148] This embodiment describes the government affairs data storage method based on the dual-chain structure of the block chain from the side of the ID card chain and the business data chain.

[0149] The government affairs data storage method based on the blockchain double-chain structure of this embodiment specifically includes:

[0150] S201: The identity link receives the data storage request sent by the client via the proxy server, verifies the identity of the requesting user and the storage operation authority, and returns the verification result to the proxy server:

[0151] If the verification fails, a data storage rejection request is sent to the client via the proxy server;

[0152] If the verification is passed, a data storage request is submitted to the business data link via the proxy server.

[0153] In a specific implementation, the user (data provider) uploads the data to be stored to the proxy server through the client.

[0154] It should be noted that the ...

Embodiment 3

[0165] This embodiment describes the government affairs data storage method based on the blockchain double-chain structure from the proxy server side.

[0166] The government affairs data storage method based on the blockchain double-chain structure of this embodiment specifically includes:

[0167] S301: Receive data uploaded by the client;

[0168] In a specific implementation, the user (data provider) uploads the data to be stored to the proxy server through the client.

[0169] It should be noted that the data to be stored includes, but is not limited to, the clock-in and clock-out record data of all employees in each department within the corresponding time period, the progress data of related tasks in a specific department, and the like.

[0170] S302: Send the data storage request to the identity chain to verify the user identity and data storage request;

[0171] S303: Receive the verification result fed back by the identity chain:

[0172] If the verification fails...

Abstract

The invention provides a government affair data storage and query method and system based on a block chain double-chain structure. The government affair data storage method based on the block chain double-chain structure comprises the steps that a client uploads the data to a proxy server; the proxy server sends a data storage request to the identity chain and verifies the user identity and the data storage request; the identity chain verifies the identity of the user who makes the request and the storage operation authority, and returns a verification result to the proxy server; if the verification does not pass, the proxy server sends a data storage rejection request to the client; if the verification passes, the proxy server submits a data storage request to a service data chain, and the service data chain completes a consensus process according to the data storage request of the client and stores the data related information in a block chain system state database; and the service data chain feeds back a storage result to the client through the proxy server.

Description

technical field [0001] The present disclosure belongs to the technical field of electronic data sharing, and in particular relates to a method and system for storing and querying government affairs data based on a blockchain double-chain structure. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The traditional data sharing feature is irreversible. Once the data is sent to the user, the data cannot be retrieved, and its diffusion and use cannot be restricted. The traditional data transaction process will also lead to many legal disputes, such as data ownership disputes and illegal reselling of data. Most of these problems are caused by the lack of effective access control of data and the opacity of data transaction information, which has caused great difficulties for data owners to prove, pursue accountability and protect rights. Govern...
