A simple and high-hiding capacity method for hiding digit-by-digit data in images based on modulus function. (English) Zbl 1059.68154

Summary: This study presents a simple method for high-hiding capacity. The basic concept uses a modulus operation. The proposed method has the following advantages: (1) the proposed method outperforms the simple LSB substitution method given the same range (\(0-m -1\)) of data digits in the embedded data; (2) the proposed method achieves good image vision quality without the need for post-processing; (3) the proposed method is almost as simple as the LSB method in both coding and decoding; (4) the smaller error advantage over the simple LSB substitution method can also be mathematically verified; (5) the error is smaller than \(\lceil (m-1)/2\rceil\) for almost every pixel; (6) the proposed method has high-hiding capacity (for example, the proposed method can hide a \(256 \times 256\) or \(256 \times 512\) image in a \(512 \times 512\) host image).
