At the same time, the existing blockchain-based data management system cannot retrieve whether the system stores relevant user information based on user information, and cannot review and use the user's previous information, so the efficiency is low. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a data management system based on blockchain, which has the characteristics of high system security and the ability to review the user's previously stored information.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a data management system based on blockchain, the data management system based on blockchain comprising a device data retrieval module, a device data collection module, a device data encryption module, a device data screening module, a device data security module and a device data output module;

[0006] The device data retrieval module retrieves previously stored information according to user login information, and generates a new user storage unit if there is no previous data;

[0007] The device data collection module monitors the device operation status of the blockchain system in real time and collects device data;

[0008] The device data encryption module encrypts the transmission and storage processes of the collected device data;

[0009] The device data screening module classifies and manages the device data stored in the blockchain node and cleans up duplicate and redundant device data;

[0010] The device data security module generates questions based on user information, and the user can output subsequent data by answering the correct questions;

[0011] The device data output module retrieves the device data stored on the blockchain node as required, and visualizes the retrieved device data to obtain simple and intuitive device data.

[0012] Furthermore, the user login method is logging in using a mobile phone number plus a verification code.

[0013] Furthermore, after the new user storage unit is generated, the user storage unit is automatically deleted when the user does not store data.

[0014] Furthermore, the generated question is based on the user's date of birth.

[0015] Furthermore, the number of times of answering the question is three times.

[0016] Furthermore, the execution of the blockchain-based data management system includes the following steps:

[0017] S1, based on the device data retrieval module, retrieve the previously stored information according to the user login information, and generate a new user storage unit if there is no previous data;

[0018] S2, based on the device data collection module, real-time monitoring of the device operation status of the blockchain system and collection of device data;

[0019] S3, encrypting the transmission and storage processes of the collected device data based on the device data encryption module;

[0020] S4. Classify and manage the device data stored in the blockchain node based on the device data screening module, and clean up duplicate and redundant device data;

[0021] S5. The device data security module generates questions based on user information, and the user can output subsequent data by answering the correct questions;

[0022] S6. Based on the device data output module, the device data stored on the blockchain node is retrieved as required, and the retrieved device data is visualized to obtain simple and intuitive device data.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention sets up a device data security module. When the system needs to output simple and intuitive observation data, the system retrieves the user information inside the system and generates questions. The user in front of the device answers the questions. After the answer is correct, the data can be output. If the answer is wrong, the device is locked to avoid leakage of the output data caused by someone other than the user in front of the device.

[0025] 2. The present invention sets up a device data retrieval module. When a user logs in to the system, the system searches to see whether there is any previous information of the user stored. If so, the system retrieves the information for the user to use. If not, a new user storage unit is generated. Setting up the device data retrieval module improves the system working efficiency and avoids duplicate data collection. BRIEF DESCRIPTION OF THE DRAWINGS
