Abstract: Based on the order preserving encryption method for numeric data, this paper proposes a fuzzy match encryption method for character data in the database. Encryption principle, process, algorithm property and robustness analysis are described. The experiment is done, and experiment results show that the method can improve robustness, and the response speed problem of query processing is solved effectively.
