There is a shortcoming in reversible data-hiding algorithm in encrypted images, it is the low capacity. we put forward a new algorithm oriented security application in cloud computing, in the new algorithm of reversible data-hiding algorithm in encrypted image, we bring in cloud computing service and singular value decomposition based on matrix. Using the powerful computing and storage capacity, compute the singular value decomposition of some selected bit planes of the encrypted image, and store the recovery dictionary that generated in this process, in the end ,we directly embed the information into the singular value matrix. Experimental results show that under the premise of ensured image privacy security and higher image fidelity, the embedding capacity has been significantly improved, and the image can be fully recovered after information extraction. In the same time, the processes of information extraction and image restoration are separable. Compared with other algorithms, it has higher embedding capacity.
