Embodiment 1

[0035] The system structure in this embodiment is divided into 3 layers, such as figure 1 As shown, from top to bottom is the data transaction layer, that is, the UI layer, which is responsible for displaying basic information on the tradable data on the chain; in the middle is the core function layer, which manages the rights of personal data through multi-layer contracts. The storage and retrieval of is also realized through this layer; the last layer is the blockchain layer. It is used to support the operation of smart contracts and the storage of data.

[0036] Among them, the data transaction platform is a display platform for data commodities in the personal data transaction method and system. The data transaction platform displays the basic information of personal user data in the form of commodities. Data buyers search and filter commodities that suit their needs through this platform. , get the seller's address and data attribute description of the commodity, includi...

Embodiment 2

[0063] This embodiment also includes the personal terminal, data buyer, data transaction platform module, and main management contract module in Embodiment 1. In this implementation, the functions of the above modules are not described, and the transaction contract module is also included.

[0064] The difference from Embodiment 1 is that the method for realizing the above system, such as image 3 Shown:

[0065] S1. The user first creates a user management contract and a data storage contract through a personal terminal and uses a smart contract template to obtain the contract address;

[0066] S2. The user initiates a registration request by calling the main management contract on the personal terminal, and registers the personal data storage contract in the main management contract by passing in the contract address;

[0067] S3. The user uses the symmetric encryption algorithm to encrypt the personal data on the chain by calling the data storage contract module on the per...

Abstract

The invention discloses a personal data transaction system and method, and the system comprises a data transaction platform which is used for displaying data commodity information; a main management contract module which is used for constructing a storage contract, controlling the authority of the storage contract and processing data transaction; a data storage contract module which is used for storing the personal data and managing the personal data; a personal terminal module which is used for calling contract management data and authorizing data transaction; and a data purchaser module which is used for browsing through the data transaction platform to obtain the data commodities meeting the requirements. According to the scheme, a user can use the system more safely and conveniently, operation steps are reduced, the data are directly encrypted, the data are directly stored in a decentralized distributed system after being collected, self-management of the personal data is truly achieved, the whole transaction process of the data is executed through an intelligent contract, a third party does not need to operate and interfere, and data leakage is prevented.

Description

technical field [0001] The present invention belongs to the technical field of information security, and in particular relates to a personal data transaction method and system, and more specifically, to a personal privacy information protection and authentication system and method based on Login Easy APP. Background technique [0002] With the expansion of the scale of the Internet and the increase of user demand, the development of cyberspace brings convenience and speed to people, but also brings new challenges to personal and national security and social stability. The existing technologies based on centralized platforms Data management and transaction methods have become the current mainstream network identity authentication management mechanism because of their simple use, strong reliability, easy deployment, and low cost. At the same time, it is necessary to collect a large amount of user-generated data when browsing the web, purchasing items, and using IoT products. A...
