Since cloud server might not be enough safe and reliable, in order to keep the security, data were usually stored in encrypted form in the cloud. Searchable encryption focused on the safety, reliability, and efficiency of search process, ensured that the user can support keyword search over encrypted data, and did not affect its use experience at the same time. Compared with traditional passwords, biometrics passwords were more convenient to be taken and hard to be forgotten. This paper would construct a new searchable encryption system based on biometrics and proposed two schemes based on different difficult problems. Compared with the existing searchable encryption schemes, with combining biometrics, our new schemes improved the flexibility, practicability and security. In this paper, our scheme satisfied the safety of indistinguishability of chosen keywords and trapdoor %K 可搜索加密 %K 生物特征 %K 关键词 %K 双线性对 %K < %K br> %K biometric %K searchable encryption %K keyword %K bilinear pairing %U http://lxbwk.njournal.sdu.edu.cn/CN/10.6040/j.issn.1671-9352.0.2015.269
