Embedding Algorithm in Steganography
Abstract
Image steganography is the art of hiding information into the cover image in such a way that no one; apart from the sender and intended recipient even understand there is hidden message. In this paper, a novel steganography technique mainly based on joint photographic expert group (JPEG) is proposed. This technique is based on 2-D Block-DCT, where DCT is used to transform original image (cover image) blocks from spatial domain to frequency domain.
