Abstract

The security of digital image in the process of cloud environment transmission becomes one of the research hotspots in the field of information security. In order to overcome the problems of insufficient camouflage ability, susceptibility to malicious attacks, and limited information hiding space in traditional reversible information hiding algorithms in the ciphertext domain, this paper proposed a high-capacity ciphertext domain reversible information hiding algorithm based on image camouflage encryption and bidirectional interpolation extension. This algorithm firstly employed two techniques, such as VQ coding and discrete wavelet transform, to perform camouflage encryption on the original image, ensuring secrecy and secure transmission of the image in cloud environments. Then, it utilized an information hiding technique based on bidirectional interpolation extension to embed secret information into the camouflaged encrypted image, achieving high-capacity information hiding. The experimental results show that the proposed method not only achieves image camouflage, but also has no obvious visual difference with the original image. The peak signal-to-noise ratio(PSNR) reaches more than 40 dB, indicating a good camouflage effect on the original image. It also achieves high-capacity secret information embedding with an average embedding rate of the image approaching 0.6 bpp with outstanding experimental performance.
