Secure Multi-Media Steganography with AES Encryption

Abstract: In today’s digital era, secure communication is of the utmost importance to protect sensitive information from unauthorized access. This paper presents a robust steganography system that integrates the Advanced Encryption Standard (AES) encryption with multimedia steganography techniques to ensure end-to-end data confidentiality and integrity. The proposed system supports text, image, audio, and video steganography, enabling secure information embedding within digital media.ThecryptographicimplementationleveragesAES-256-CBC encryption,withkeyderivationbasedonPBKDF2toresistbruteforceattacks.Forsteganographicembedding,text-basedhiding utilizes zero-width characters, image steganography employs theLeastSignificantBit(LSB)technique,audiosteganographymodifies PCM samples, and video steganography manipulates frame data.
