| Abstract: | Although it is convenient to exchange data by publishing view, some information may be disclosed in the publishing process, Therefore, it is a new issue of database security to ensure the publishing view safety. This paper proposes the theorem of query-view security determining and method of measuring disclosure, and gives algorithm of eliminate the information disclosure. Experimental results show that algorithms eliminate the information disclosure efficiently, and ensure the view security. |
