Novel Magic Matrices Generation Method for Secret Messages Embedding

摘要

A flexible data-hiding scheme based on exploiting modification direction (EMD) is proposed in this paper. Our proposed scheme will satisfy objectives users who want to produce high-quality stego images or want a huge hiding capacity. This flexibility is accomplished by a novel magic matrix function developed in our proposed scheme. Our magic matrix function can generate multiple magic matrices with a hiding capacity is decided by users. Then, all the generated magic matrices are tested to find an optimal one that produces the highest-quality stego image. The experimental results show that our proposed scheme outperforms other methods.
