With the development of Internet technology and the continuous improvement of informatization,the number of netizens in my country will reach 1.011 billion in2021.With the continuous increase in the number of Internet users,various websites and Internet companies have collected a large amount of user personal information.However,in recent years,the leakage of users’ personal information has been increasing year by year,causing heavy losses to enterprises and users.For the company,how to safely store the personal information entered by the user,how to transfer and transmit user information safely when necessary,how to effectively supervise the data administrators within the company,and also for the company’s management of personal information Security protection capabilities and data management capabilities present enormous challenges.Aiming at the protection of website users’ personal information,this dissertation designs and implements a website user’s personal information management system,which provides multi-angle protection for personal information by satisfying multiple different scenarios.The website user personal information management system designed in this paper is divided into four modules:Firstly,design the website user’s personal information collection module.This module obtains the registration information filled in by the user from the website registration page,encrypts the information and stores it in the database of the server.Users can log in to the website to modify personal information,and the modified content will be updated and saved in the database after encryption.Secondly,design the personal information query and selection module.Authorized departmental data administrators can search for the personal information they need through the system,display it after decryption,and export the search results.Thirdly,design the personal information encryption export and import module.Authorized departmental data administrators can decrypt and export qualified personal information.In order to ensure the security of personal information,personal information is protected by the system using hybrid encryption technology.The exported encrypted personal information is decrypted and imported into the local system by an authorized departmental data administrator.Finally,design the tracking and recording of the information export operation module.This thesis uses the private chain technology in the blockchain technology to build the Ethereum private chain and design the smart contract,record the export and import operations of personal information,and strengthen the supervision of the operations of data managers.It can more effectively track and record the flow of personal information of website users.After realizing the four modules of the above-mentioned system,this thesis tests the function and performance of the system.The experimental results show that the website user personal information management system proposed in this thesis has a simple user interface,convenient operation,can quickly store and display user personal information,can transmit personal information safely,and successfully record and upload the transmission situation to the private chain.The system responds quickly,safely and reliably. |
