It is important to securely send information through the Internet; thus, technologies for safely exchanging information are required. One such technology is steganography, which conceals confidential data in multimedia. Although numerous embedding methods have been proposed, increasing embedding capacity, controlling image-quality degradation, and confidentiality are still issues that need to be addressed. There is a method that uses the correlation property of a maximum length sequence (M-sequence) to improve embedding capacity. However, since this method is used in watermarking, which is closely related to steganography, it cannot be directly applied to steganography, which requires a large amount of secret information to embed, because image quality would significantly degrade. We propose two steganography methods that use the correlation property of M-sequence. Particularly, we focused on the improvement of the intensity factor, which is a factor of image-quality degradation. As a result, a significant improvement in image quality was achieved.
