Research on sensitive data encryption based on B/S network

Currently B/S network architecture is of distributed characteristic and vast data information is stored in the secure database server, however, the secure database service based on data encryption technology in such network environment cannot effectively balance data processing and data privacy protection. Therefore, to overcome the foresaid problem, a new privacy protection method of secure database service based on B/S network has been put forward in this paper. By introducing the automatic testing technology of quasi-sign attribute set, part sensitive attributes are encrypted and the quasi-sign attribute set are decomposed to achieve vertical decomposition of data; distributed query processing is realized by the query decomposition of encrypted data. The experiment results indicate that this method can balance the contradiction between query and privacy protection better.
