LSB Image Steganography System: Design and Implementation

This project encompasses the design and implementation of an LSB image steganography system, including the development and coding of LSB algorithms, analysis of steganographic attack methods with corresponding defense strategies, DCT-domain hiding techniques, along with applications and research in digital watermarking. Key implementation aspects include: - LSB algorithm implementation using bitwise operations to embed secret data in least significant bits of pixel values - Steganalysis algorithms for detecting hidden information through statistical analysis and pattern recognition - DCT-based hiding techniques that transform image data to frequency domain for more robust embedding - Digital watermarking systems incorporating perceptual models and error correction coding The system demonstrates practical approaches for information hiding while addressing security challenges through multiple embedding domains and detection-resistant techniques.
