Secured Messenger Application

Abstract

Now days, Communication platforms especially Messaging applications with all their varieties have become an essential part in our lives, not just a luxury but a necessity , and with the enormous growth of these apps among everyone, people have started to worry about their privacy and the safety of their data, as the majority of these messaging applications companies manage and store user data centrally, which threatens and puts it at risk. This centralized architectures have many vulnerabilities which led to many leaks in users data, issues and con icts regarding the safety of users and their privacy. all of this have triggered and motivated the research community to look to develop an alternative which is decentralized architectures with the main purpose of providing safety while giving users full control over their own data, relationships and activities. The aim of this work is to develop a new decentralized secured messenger based on Block chain technology, which is a revolutionary technology that doesn't require central entity to manage and control everything, to secure data access in the storage space, authentication and registration processes and perfect identity management, in order to guarantee the users information. Therefore, we will present the Stacks platform that we have chosen initially for the development of our application taking advantage of its functionalities as well as representing a simulation application which will demonstrate how a decentralized messenger should function. The reason we developed a simulation app is that we weren't lucky as there wasn't enough time for us to nish our app on the stacks platform.
