A Novel Digital Image Hiding Scheme Based on Matrix Decomposition

Digital image is an important way to get information, so people pay more attention to the security of digital images. The technology of digital image hiding was born in order to enhance the security of digital images. The stego-images obtained by some hiding methods will not get people´s attention, which will protect digital images from being modified or destroyed. In this paper, a novel digital image hiding scheme based on matrix decomposition is proposed. The image quality of the stego-image can be greatly improved with low extra computational complexity. Experimental results show that the stego-image is visually indistinguishable from the original cover image.
