Abstract: This project presents a secure and efficient method for embedding audio files into digital images using Least Significant Bit (LSB) encoding, ensuring covert communication while preserving the visual integrity of the carrier image. To enhance security, private PIN encryption prevents unauthorized access, while self-destructive encryption ensures time-based deletion of hidden data. Additionally, an intelligent compatibility alert system detects potential encoding issues, ensuring seamless operation across different devices. A hidden data verification system determines whether an image contains embedded audio, reducing errors during extraction. The application supports both recorded and existing audio files for encoding, making it ideal for secure messaging, encrypted communication, and digital watermarking. Developed using Cordova for both web and Android, the system ensures cross-platform compatibility and an intuitive user experience. It plays a crucial role in cybersecurity, intellectual property protection, and covert data transfer, offering a reliable and user-friendly solution for modern digital communication.
