We proposed an adaptive steganography of an optical image using bit-planes and multichannel characteristics. The experiment s purpose was to compare the most popular methods used in optical steganography and to examine ’ their advantages and disadvantages. In this paper we describe two digital methods: the first uses less significant bits (LSB) to encode hidden data, and in the other all blocks of n n pixels are coded by using DCT (Digital × Cosine Transformation), and two optical methods: double phase encoding and digital hologram watermarking with double binary phase encoding by using IFTA(Iterative Fourier Transform Algorithm) with phase quantization. Therefore, we investigated the complexity on bit plane and data, similarity insert information into bit planes. As a result, the proposed method increased the insertion capacity and improved the optical image quality as compared to fixing threshold and variable length method.
