Smart Contact Lock: A Standalone App for Advanced Mobile Security against Hacking

In the digital era, mobile security is a growing concern, with unauthorized access and phone hacking posing serious threats to user privacy. This research focuses on the development of Smart Contact Lock, a standalone mobile application designed to provide advanced security for user contacts against cyber threats. Unlike traditional phone security measures, this app incorporates artificial intelligence (AI) and blockchain technology to enhance encryption, authentication, and intrusion detection. The app ensures secure contact storage, real-time monitoring, and multi-layer authentication mechanisms such as PINs, biometrics, and pattern locks. The study evaluates the effectiveness of Smart Contact Lock through security testing and user feedback, demonstrating its ability to significantly improve contact privacy and protect against unauthorized access.
