A Fast Image Hiding Scheme Based on Chaotic Map and Matriz Singular Value Decomposition

摘要：

In this paper,it is the main purpose to embed a secret image into a non-confidential image. There is a slight change to the non-confidential image,and this slight change can not be identified by the naked eyes.In the process of an image transmission,it will be useful to decrease the attackers attention. In the recent years,a variety of effective chaosbased image encryption schemes have been proposed. The typical structure of these schemes has the permutation and diffusion performed alternatively.Many current watermark algorithms insert data in the spatial or transform domains like the discrete cosine,the discrete Fourier,and the discrete wavelet transforms.In this paper,the secret image is first encrypted based on the chaotic map,the matrix singular value decomposition (SVD) of the host image and the encrypted image is then computed,the singular vectors of the encrypted image is embed into the singular vector of the host image. The proposed method leads to an imperceptible scheme for digital images,both in grey scale and color and is quite robust against attacks like noise,cropping and JPEG compression.Using Matlab toolbox,the simulation results show that the proposed encryption is easily realized and the encryption speed is accelerated.
