A new steganography method using image layers

In this study we propose a new steganography method based image layers. The proposed method divides the host image into blocks and embeds the corresponding secret data bits into each block using the layers generated by the binary representation of pixel values. Given a secret bit sequence, it performs a search on the rows and columns of the layers for finding the most similar row or column. The location of row/column and its differences from the secret data is then marked by modifying minimum number of bits in the least significant bits of the blocks. In the experiments, randomly selected secret messages are embedded into 100 different images. The performance of the proposed method against steganalysis techniques is evaluated using the measure of distorted pixels. The method outperforms the other steganography techniques in terms of image quality.
