Embodiment 1

[0027] figure 1 It is a flow chart of a data processing method based on blockchain provided by Embodiment 1 of the present invention. This embodiment can be applied to the situation where the user's personal information data is safely managed based on blockchain technology. This method can be implemented by the present invention The block chain-based data processing device or equipment provided in the embodiment can be implemented, and the device can be implemented in the form of 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 a data demander type and a query requirement.

[0029] Wherein, the data demander node may be a node in the blockchain, or a node that can participate in the blockchain through a web page, platform, or application program. Data demanders (such as talent recruitment websites, financial ser...

Embodiment 2

[0041] figure 2 It is a flow chart of a blockchain-based data processing method provided by Embodiment 2 of the present invention. This embodiment is further optimized on the basis of the foregoing embodiments. 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 a data demander type and a query requirement.

[0043] S202. Based on the authorized access rules in the smart contract, search the blockchain for target user data that matches the type of the demander and the query requirement.

[0044] S203. Feedback the target user data to the data demander node.

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

[0046] Among them, smart contracts include not only authorized access rules, but also rev...

Embodiment 3

[0057] image 3 It is a flow chart of a blockchain-based data processing method provided by Embodiment 3 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 node, where the data upload request includes at least user data to be uploaded and an identity.

[0059] Wherein, 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 program. The user can upload his own user data (such as one or more of name, mobile phone number, address, preference or ID number) through this node. Specifically, it may be that the user side uploads its own user data through the user side node. When the user side node detects that the user data upload is completed (for example, it may be a signal triggered by detecting that the user clicks a button; W...

Abstract

The invention discloses a block chain-based data processing method, device, equipment and storage medium. Wherein, the method includes: receiving a data query request sent by a data demander node; the data query request includes at least the type of the data demander and query requirements; based on the authorized access rules in the smart contract, searching from the blockchain The target user data whose type of demander matches the query requirement; and feeds back the target user data to the data demander node. It can effectively avoid leakage of user information and improve data security.

Description

technical field [0001] Embodiments of the present invention relate to computer data storage technology, and in particular to a blockchain-based data processing method, device, device, and storage medium. Background technique [0002] With the development of the mobile Internet, people's lives are completely inseparable from the Internet, and people's basic necessities of life can be completed through Internet services. When users use websites or applications, they usually need to enter relevant user data, such as name, phone number, address and preferences, etc. At present, most websites or applications have poor management security for acquired user data, and user data leaks often occur. Once the leaked data is illegally abused, it will bring certain troubles to users and even cause large economic losses. loss. Contents of the invention [0003] Embodiments of the present invention provide a blockchain-based data processing method, device, device, and storage medium to ...
