Abstract
- The world has witnessed a rapid surge in wireless technology and mobile device adoption, but this growth has brought along significant cybersecurity vulnerabilities. This paper is centered around the dangers posed by unauthorized communication and data leakage through smartphones. It delves into the challenge of covert communication and the potential weaknesses that allow sensitive information to be leaked. To address these concerns, the paper introduces a specialized smart system aimed at countering unauthorized communication and preventing data leakage effectively. This proposed system disrupts unauthorized communication channels, safeguarding against potential breaches. A fully functional prototype is developed using software-defined radio technology and extensively tested with real-world cellular communications scenarios to demonstrate its operational effectiveness. By highlighting these vulnerabilities and providing a robust solution, this paper aims to fortify the security of wireless technology and enhance protection against unauthorized access and data breaches via smartphones.
