Steganography
abstract
According to my study I propose a new steganography method based on 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. Based on a secret bit sequence ,the system performs a search on the rows and columns of the layers for finding the most similar row or column and the location of row or column and its differences from the secret data will be marked by modifying minimal number of bits in the LSB of the blocks. In the experiments, randomly selected secret messages are embedded into several different images. The performance of the proposed method against steganalysis techniques is evaluated using the measure of distorted pixels.
