Cover-stego image classification
WebAug 8, 2008 · Abstract In steganography, the cover medium is widely treated as a mere container for the embedded information, even though it affects the stego-image quality, … WebDec 23, 2024 · DCT steganography starts with partitioning the cover image into 8 × 8 pixel blocks (Fig. 2 a). For each block, the pixels are transferred into the frequency domain. This results in an 8 × 8-frequency energy matrix (also known as a coefficient matrix) that describes the block (Fig. 2 b).

WebJan 8, 2024 · 1 Introduction Steganography aims at hiding a private message inside an innocuous cover image and communicates it over public communication channel and finally extracting the hidden secret message at the communication target. The primary security features of a steganographic scheme are imperceptibility and undetectability.

WebDec 6, 2024 · Conventional covert image communication is assumed to transmit the message, in the securest way possible for a given payload, over lossless channels, and the associated steganographic schemes are generally vulnerable to active attacks, e.g., JPEG re-compression, scaling, as seen on social networks. Although considerable progress … WebThe existing GAN-based steganography approaches mainly studied in images cover, less work is conducted on audio cover. In addition, though a few GAN-based audio steganography methods have been proposed, they still have room for improvements in perceptual quality and undetectability.
WebDec 1, 2024 · In steganography with image, the message is embedded in the carrier image, such that it generates very negligible modifications in the cover image. A genetic algorithm method is used to select a carrier image from a set of image database. The chosen carrier image should be more suitable with the given message. WebWhat is Stego Image. 1.
