摘要
In this paper, we propose a novel scheme that can achieve data privacy by hybrid cloud, which consists of public and private cloud, and reduce storage and computation in private cloud, as well as communication overhead between private and public cloud. Meanwhile, we propose a novel algorithm to process private image data. Our experimental results show that (1) our algorithm achieves data privacy but only takes about 1/1000, time of the Advanced Encryption Standard algorithm and (2) the delay of our hybrid cloud approach (including the private and public cloud communications) is only 3%- 5% more compared with the traditional public cloud- only approach.
