Problems solved by technology

The inventor found that in this mode, there are risks of privacy leakage in multiple links in the data sharing process, including government staff leakage, system attack leakage, user staff leakage, etc. In addition, there is no complete record of the data transfer process, even if There are log records, and there is also the risk of being deleted or tampered with. When a data leak occurs, it cannot be located and held accountable, and supervision is difficult.

Embodiment 1

[0036] Such as figure 1 As shown, a blockchain-based government data protocol authorization sharing method in this embodiment includes:

[0037] Step 1: After the owner signs the government data authorization agreement and puts the agreement on the chain, receive the government data request sent by the user, and sort out the relevant government data to form a data file.

[0038] In the specific implementation, the user pushes the authorization agreement to the data owner based on the message notification method, and the owner calls the agreement signing module to sign the authorization agreement. in the blockchain account.

[0039] Among them, the government data authorization agreement includes the name of the data to be authorized, the purpose of the data, the disclaimer and the subject information of the signatory.

[0040] The user invokes the data request module to edit the data request, and sends it to the issuer. The issuer receives the data request, organizes the dat...

Embodiment 2

[0050] This embodiment provides a block chain-based device for government data protocol authorization sharing, which includes:

[0051] The data request receiving module is used to receive the government data request sent by the user after the owner signs the government data authorization agreement and puts the agreement on the chain, and sorts out the relevant government data to form a data file;

[0052] The data issuance module, which is used to encrypt the data on the chain by multiple parties, and then issue it to the blockchain account of the owner, and send the issuance message to the user, so that the user can obtain the encrypted data according to the access address in the issued message. The data file, decrypt the data to obtain the original data, and push the data sharing completion notification to the owner and issuer at the same time;

[0053] The message notification receiving module is used for information push between multiple parties, such as the owner and the...

Embodiment 3

[0057] Such as figure 2 As shown, this embodiment provides a blockchain-based device for government data protocol authorization sharing, which includes two parts: a blockchain support system and a protocol authorization device.

[0058] The blockchain support system includes a contract management module, an account management module, a transaction management module, a large file storage management module and a blockchain transaction ledger module, providing blockchain services for protocol authorization devices.

[0059] The contract management module formulates corresponding contracts for the government data and authorization agreements on the chain, by defining the government data, the parties involved in the agreement (issuer, user, owner) and their permissions, and executable operations (issue, acquisition, update) , deregistration, access restrictions), asset status (available status, unavailable status), restrict and regulate the operation of government data and agreeme...

Abstract

The invention belongs to the technical field of blockchain application, and provides a government data protocol authorization sharing method and device based on a blockchain. The method comprises the following steps: after an owner signs a government data authorization agreement and links the agreement, receiving a government data request sent by a user, and organizing related government numbers to form data pieces; encrypting and chaining the data piece through multiple parties, signing and issuing the data piece to a blockchain account of an owning party, and sending a signing and issuing message to a user, thereby enabling the user to obtain the encrypted data piece according to an access address in the signing and issuing message, decrypting the data to obtain a data original text, and pushing a data sharing completion notification to the owning party and an issuer at the same time; and receiving a data sharing completion notification pushed by the user, wherein the data protocol authorizes the completion of sharing. A blockchain multi-party encryption technology is utilized, data privacy, security and ownership are guaranteed based on a signing protocol, and government data is directly shared between an issuer and a user.

Description

technical field [0001] The invention belongs to the technical field of block chain application, and in particular relates to a method and device for authorized sharing of government data protocols based on block chain. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Government agencies, as data issuers, have a large amount of personal and business-related data, such as provident fund information, insurance information, income information, business information, tax information, company change information, qualification information, and other data. Under the traditional model, when data owners such as individuals and enterprises handle business, they often need to go to government authorities or issuing departments to issue certification documents, and then go to the data user to submit relevant materials, running back and forth, which is ti...
