Introduction Image steganography represents a critical technique in information security, enabling the concealment of secret data within carrier images while maintaining visual appearance. This article presents a novel approach to grayscale image steganography based on Discrete Cosine Transform (DCT) block processing combined with histogram equ ...

Introduction Image steganography conceals secret data within a cover image. This method utilizes the Discrete Cosine Transform (DCT) and histogram manipulation to embed information into grayscale images, aiming for robustnes and imperceptibility. Methodology The proposed technique involves the following key steps: DCT Block Processing: The cov ...
