Yiwen Liang · Jisuanji gongcheng · 2005
The authorization mechanism of operating systems usually puts importance on access control on the bias of taking a file as an isolated object, but ignores the security relationship between files, which implies many flaws. On the inspiration of describing the relationship between objects by means of lineage, a file lineage security model was presented, and its performance and security characteristics were analyzed.
