Securing Confidential Information on WhatsApp with Blockchain Technology

The protection of sensitive information is a major concern in today’s world. However, when it comes to preventing unauthorized screenshots, technology has yet to catch up. Despite this, the concept of securing data is not new, as we now live in an era where human beings are constantly connected to the internet, which is accessible 24/7 like a public park. Information is being shared at an incredible rate every second, and some of this information is particularly sensitive. If it falls into the wrong hands, it can lead to significant losses. This paper proposes a blockchain-based solution to prevent the misuse of WhatsApp screenshots. By using blockchain technology to create a network of shareable images, which are identified by their address and maintain a record of their previous sharing history, security can be improved. This approach also eliminates the need for a middleman to transmit data, reducing the cost of the proposed system.
