Study Notes

Protecting shared data from interception on public networks is essential.
Steganography, an approach to concealing data, is a practical solution for this challenge.
Hiding confidential information within digital media like images can result in image distortion, which can raise suspicions.
Researchers have developed various steganographic algorithms to minimize image distortion.
The study proposes a steganographic methodology based on difference expansion (DE) logic to improve stego image quality and achieve a PSNR of 62.7512 dB.
