Embodiment 1

[0027] figure 1 This is a flowchart of a blockchain-based data processing method provided in the first embodiment of the present invention. This embodiment can be applied to the situation where the user’s personal information data is securely managed based on blockchain technology. This method can be implemented by the present invention. The block chain-based data processing device or device provided in the embodiment is executed, and the device can be implemented in hardware and / or software. Such as figure 1 As shown, it specifically includes the following steps:

[0028] S101: Receive a data query request sent by a data demander node; the data query request includes at least the data demander type and query demand.

[0029] Among them, the data demander node can be a node in the blockchain, or a node that can participate in the blockchain through a webpage, platform, or application. Data demanders (such as talent recruitment websites, financial service companies, business salesm...

Embodiment 2

[0041] figure 2 This is a flowchart of a data processing method based on blockchain provided in the second embodiment of the present invention. This embodiment is further optimized on the basis of the foregoing embodiment. See figure 2 , The method specifically includes:

[0042] S201: Receive a data query request sent by a data demander node; the data query request includes at least the data demander type and query demand.

[0043] S202: Based on the authorized access rules in the smart contract, search for target user data matching the demander type and query requirements from the blockchain.

[0044] S203: Feed back target user data to the data demander node.

[0045] S204: If it is detected that the data demander node receives the data successfully, determine the usage fee of the target user data according to the revenue management rule in the smart contract.

[0046] Among them, the smart contract includes not only authorized access rules, but also revenue management rules. Re...

Embodiment 3

[0057] image 3 This is a flowchart of a blockchain-based data processing method provided in the third embodiment of the present invention. This embodiment is further optimized on the basis of the foregoing embodiments. See image 3 , The method specifically includes:

[0058] S301: Receive a data upload request sent by a user-side node, where the data upload request includes at least user data to be uploaded and an identity identifier.

[0059] Among them, the user-side node can be a node in the blockchain, or a node that can participate in the blockchain through a webpage, platform, or application. The user can upload his user data (such as one or more of name, mobile phone number, address, preferences or ID number, etc.) through this node. Specifically, it can be that the user uploads its own user data through the user-side node. When the user-side node detects that the user data upload is complete (for example, it can be a signal triggered by the detection of the user clickin...

Abstract

The invention discloses a block-chain-based data processing method, device, apparatus, and storage medium. The method comprises the following steps: receiving a data inquiry request sent by a data requesting node; the data inquiry request at least includes a data demand type and a query demand; searching target user data matching the demand side type and the query demand from a block chain based on an authorized access rule in an intelligent contract; feeding back the target user data to the data requesting node. The invention can effectively avoid the leakage of user information and improve the security of data.

Description

Technical field [0001] The embodiments of the present invention relate to computer data storage technology, and in particular to a data processing method, device, equipment and storage medium based on blockchain. Background technique [0002] With the development of the mobile Internet, people's lives are completely inseparable from the Internet, and people's food, clothing, housing and transportation can be completed through Internet services. When users use a website or application, they usually need to enter relevant user data, such as name, phone number, address, and preferences. At present, most websites or applications have poor management security for the acquired user data, and user data leakage often occurs. Once the leaked data is illegally abused, it will bring certain troubles to users and even cause greater economic loss. loss. Summary of the invention [0003] The embodiment of the present invention provides a data processing method, device, equipment, and storage ...
