Digitisation for access to preserved documents

Regulating Access to XML documents

In this paper, our objective is to define a security model for regulating access to XML documents. Our model offers a security policy with a great expressive power. An XML document is represented by a tree. Nodes of this tree are of different type (element, attribute, text, comment...etc). The smallest protection granularity of our model is the node, that is, authorisation rules granting or den...

The best associations are selected on the basis of measures of confidence. To reduce the combinatory explosion of associations, because images of the database contain very large numbers of colors and textures, we consider a visual dic...
