Binding method of security marking and data objects based on extensive markup language (XML)

The invention discloses a binding method of security marking and data objects based on extensive markup language (XML). The binding method of the security marking and the data objects based on the XML utilizes an XML tree-form layering structure to identify information of different sensitive levels, achieves characters of protection and visiting controlling of high-level particle size of elements even attributes. First of all, the data objects and even isomerous data objects are integrally shown in the XML tree-form structure, and corresponding security marks are added on the data objects described by the XML data files according to differences of sensitive degrees of data content of the data objects, high-graded and strengthened protection and visiting control of the data objects described by the XML data are achieved by enabling the XML security marks to be related or bound into elements or attributes of the XML data files, and therefore the defections that marking binding technology in the prior art is coarse in protecting particle degree, and incapable of achieving high particle degree visiting are solved.
