Abstract
This letter presents a novel image steganography method that utilizes a two-way block-matching procedure to search for the highest similarity block for each block of the important image. The bases and indexes obtained together with some not-well-matched blocks are recorded in the least significant bits of the cover image using a hop scheme. The method exhibits a high data payload, which reduces the storage and transmission-time requirements and also provides a method that prevents an observer from selectively blocking the transmission of the important image.
