Kecekapan pemasukan merupakan isu penting dalam kaedah steganografi. Pembenaman matriks (1, n, h) steganografi telah dicadangkan oleh Crandall untuk mencapai kecekapan pembenaman yang tinggi untuk imej palet. Kertas kerja ini mencadangkan kaedah steganografi berdasarkan pembenaman matriks berbilang lapisan untuk imej palet. Pertama, tugasan pariti disediakan untuk meningkatkan kualiti imej. Kemudian, pembenaman matriks berbilang lapisan (k, 1, n, h) dipersembahkan untuk mencapai kecekapan dan kapasiti pemasukan yang tinggi. Tanpa mengubah suai palet warna, hk bit rahsia boleh dimasukkan ke dalam n piksel dengan menukar paling banyak k piksel. Di bawah kapasiti yang sama, kecekapan pembenaman kaedah yang dicadangkan dibandingkan dengan kaedah steganografi berasaskan piksel. Perbandingan menunjukkan bahawa kaedah yang dicadangkan mempunyai kecekapan pembenaman yang lebih tinggi daripada kaedah steganografi berasaskan piksel. Keputusan eksperimen juga mencadangkan bahawa kaedah yang dicadangkan memberikan kualiti imej yang lebih tinggi daripada beberapa kaedah sedia ada di bawah kecekapan dan kapasiti pembenaman yang sama.

Abstract: Embedding efficiency is an important issue in steganography methods. Matrix embedding (1, n, h) steganography was proposed by Crandall to achieve high embedding efficiency for palette images. This paper proposes a steganography method based on multilayer matrix embedding for palette images. First, a parity assignment is provided to increase the image quality. Then, a multilayer matrix embedding (k, 1, n, h) is presented to achieve high embedding efficiency and capacity. Without modifying the color palette, hk secret bits can be embedded into n pixels by changing at most k pixels. Under the same capacity, the embedding efficiency of the proposed method is compared with that of pixel-based steganography methods. The comparison indicates that the proposed method has higher embedding efficiency than pixel-based steganography methods. The experimental results also suggest that the proposed method provides higher image quality than some existing methods under the same embedding efficiency and capacity.
