Reversible LSB Steganography | Secure File & Text Hiding in Images (Python Implementation)

In this video, we explain and demonstrate a reversible Least Significant Bit (LSB) steganography technique for securely hiding both text data and entire files (like PDFs) inside grayscale images.
This method ensures that:
The original image can be perfectly recovered after extraction
High imperceptibility is maintained
Metrics like PSNR, SSIM, and BPP are calculated
