Abstract
This study proposes a robust custom hybrid
framework that embeds a message into JPEG images using DCT, JPEG2000 images
using DWT, and is improved by RSA for confidentiality. An energy adaptive
weighting algorithm is used to embed message pixels into lower portions of the
frequency spectrum for imperceptibility and robustness. The method achieved
RSSD ≥ 0.996, PSNR 44.2 dB, and SSIM 0.98 on 20 images with standard evaluation
metrics after applying lossy compression, format conversion, and color palette
transformation, outperforming DCT-only, DWT-only, and GAN-based steganography
approaches. The framework demonstrates distortion-less message recovery and
resilient to compression while preserving message integrity.
