In the emerging cloud computing paradigm, data owners become increasingly motivated to outsource their complex data management systems from local sites to the commercial public cloud for great flexibility and economic savings. For the consideration of users' privacy, sensitive images have to be encrypted before outsourcing, which makes effective data utilization a very challenging task. In this paper, firstly, we define the problem of privacy-preserving query over encrypted images in cloud computing. And to solve the problem, we design a computable encryption scheme based on vector and matrix calculations. The scheme pre-builds a feature-based index to provide feature-related information about each encrypted image, and then chooses the efficient image similarity measure as the pruning tool to carry out the retrieval procedure. Security analysis and performance evaluation show that the scheme is IND-CCA.
