The Design And Implementation Of A Privacy Protection Platform For The Elderly Who Are Lost

The Help Platform for Lost Elderly Base on Privacy Protection is a system that prevents the elderly from getting lost and tracking the location of the elderly.It allows family members of the elderly(hereinafter referred to as “the people who are concerned”)to post their personal information to the platform,the platform will then generate a unique QR code for them,the family members of the elderly(hereinafter referred to as “the guardian”)can log in to the platform to view and download the QR code at any time.The guardian can attach the QR code to the clothing or other eye-catching position of the people who are concerned.When they are lost,any mobile phone scanning the QR code of the people who are concerned will notify the guardian.The guardian can also view the specific location information of people who are concerned.The entire process is encrypted,and the mobile phone number including the call will not be disclosed to the other party,thus achieving the purpose of privacy protection.The Help Platform for Lost Elderly Base on Privacy Protection is implemented by Spring Boot,Android,Vue.js and other technologies.Using the RESTful interface for client-server communication during implementation and applying MySQL database for storage,Redis database cache,greatly enhance the response speed.This paper first analyzes the current development trends and current situation at home and abroad,and integrated the advantages of the Android system,decided to develop the Android platform.Then,the paper focuses on the privacy protection.Since privacy protection is a trend in the development of big data,the privacy protection technology is indispensable.Also introduced the technology used in the development of this platform,the platform uses separate development of front and rear,using CentOS as a back-end server,using IntelliJ IDEA,Android Studio and VS Code and other software development.Finally,based on the development methods commonly used in software engineering,the paper conducts research and implementation on the need analysis,design,implementation and testing of the platform.The Help Platform for Lost Elderly Base on Privacy Protection introduced in this paper aims to help more and more people who are lost in the society,and to minimize the number of missing people,or even not.
