摘要：As cloud computing becomes most general, the important information is centralized into the cloud server. To protect the data stored in the cloud, the data must be encrypted. Although traditional encryption techniques allows the user to securely search through the keyword and return retrieved files, these techniques are useful only for exact keyword search. In this paper, we solve the problem of exact keyword match by providing searching with fuzzy keyword. We also propose two more techniques called gram based technique which is useful for reducing the time, providing fast searching and increase the performance by considering substring from the given string. And Symbol-based tree traverse search scheme where a multi way tree structure is built by using symbols, which works for more than one keywords entered by the user. By providing security, we show that the proposed solution is secure and privacy-preserving.
