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 ...

Creating a visual representation of character frequencies requires managing three core components: storage mechanisms, input processing, and rendering logic. When focusing on uppercase English letters, a fixed-size array offers efficient storage compared to associative containers. Input handling should robustly capture stream data until the end ...
