With the continuous development of information technology, database as the core part of modern information system, it undertakes the task of storage and management of data information. In the process of database query, it is of great importance to protect the security of privacy information of both parties. However, the existing programs encrypt the entire database; the encryption cost is excessively high. In order to solve this problem, the article takes the advantage of security assumptions of exchange encryption and obvious transfer technology to propose a database privacy information query program based on secure multiparty computation as well as analyzes the correctness, security, and the complexity of the design. The results show that the computational complexity of the program mentioned in the article is significantly reduced.
