Zhangjie Fu, Jie Xi, Jin Wang, Xingming Sun · 2014
As the cloud computing popularizes, sensitive data need to be encrypted before outsourcing, which makes the traditional data utilization useless. So search over these encrypted documents is a very challenging task. This paper firstly descripts the framework of the searchable encryption, and then presents the existing keyword-based search technologies. At last, we propose a novel color-based keyword search scheme for encrypted office document. Two vectors on behalf of the keywords and the corresponding color are used. The scheme can return top-k set as correct as possible meeting user's requirements.
