README for XOR_LSB_Stego
Overview
XOR_LSB_Stego is a Python-based implementation of a novel image steganography technique described in the accompanying paper. This technique enhances the security of the Least Significant Bit (LSB) replacement method by introducing an XOR operation with the 7th bit of RGB components before embedding the data in the 8th bit. This README provides instructions on installation, usage, and understanding the underlying method.

Methodology
Abstract from the Paper
The paper proposes a highly secure data hiding technique in the spatial domain of image steganography. It involves an XOR operation with the 7th bit of each RGB component, followed by embedding the output in the 8th bit. This approach ensures no trace of the original message in the cover object without using an external key. The method shows high PSNR (55.90 dB) and low MSE, indicating enhanced imperceptibility and security compared to other techniques.
Key Concepts
- Least Significant Bit (LSB) Replacement: A popular method in image steganography for its simplicity and effectiveness.
- XOR Operation: Enhances security by manipulating the 7th bit of RGB components before data embedding.
- PSNR and MSE Analysis: Used to evaluate the quality and security of the steganographic technique.
