Confidential data should be encrypted in out-souring services in cloud computing environment in order to minimise the risk of data revealing. There have been many schemes, classified as searchable encryption, which provides capabilities to securely search over encrypted data through keywords without decryption key. In this paper, we try to combine the technique of searchable encryption with a secret sharing scheme that allows us to retrieve the portion of confidential data without recovering data.
