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.
