Secure Data Hiding: A Comprehensive LSB-Based Steganography Framework With Cryptographic Enhancements

This paper explores advanced steganographic techniques for concealing various forms of data within digital media using the Least Significant Bit (LSB) method. The focus is on four key features: embedding plaintext within images, embedding AES-encrypted text within audio files, embedding AES-encrypted text within video files, and embedding images within other images. The goal is to enhance the security and integrity of the concealed data, ensuring it remains imperceptible to unintended recipients while preserving the quality of the host media. By utilizing the LSB technique, which modifies only the least significant bits of media files, the approach aims to achieve a high level of data concealment with minimal perceptual impact on the host files. The implementation integrates cryptographic algorithms with steganographic methods to provide robust and secure data hiding solutions. Plain text is embedded directly within images using LSB, while for audio and video files, text is first encrypted with the AES cipher before embedding. Similarly, the LSB method is used to embed images within other images, ensuring that the hidden content is visually indistinguishable from the original. This multi-faceted steganographic approach not only enhances data security but also offers a versatile framework adaptable to different media types, demonstrating the effectiveness of combining cryptography and steganography for digital data protection.
