“…e storage rules of StructTree in matrix are: (1) for the leaf nodes, they are saved sequentially in the diagonal from left to right and top to down; (2) for the intermediate nodes, they are saved in the lower left corner of all its children's position. Select the maximum value of the abscissa of all child nodes as the abscissa value of this node and select the minimum value of the ordinate of all child nodes as the ordinate value of this node [17].…”

“…In order to evaluate the performance of storage space, here we compare the space storage of three schemes; one is the basic storage scheme, which stores different tailored source XML documents for users with different access purposes. e second scheme is named Matrix scheme [17], which stores different tailored storage matrices for users, and the third scheme is our solution proposed in this paper, we have named it as the integration scheme.…”

In order to protect the sensitive data represented as XML documents in a trusted collaborative system where sensitive data are not shared, an XML privacy-preserving data disclosure decision scheme was proposed under the assumption of a trusted server. This scheme is inspired by the idea of separating storage structure and content. Temporary access matrix is used to represent structure authorization and the vector represents the content authorization of leaf node. According to the conversion rules, access matrix not only represents access authorization of all nodes but also keeps the main structure of the XML document. With the combination of the vector and matrix, it can provide different access views for different group users with different purposes. In addition, start-end encoding is used to encode all the nodes for locating nodes and the content; privilege matrix solves the problem of privacy synchronization change for all users. At the same time, authentication polynomials are used to verify different users and improve the security level. The experimental results show that the scheme not only effectively protects XML sensitive data but also reduces the storage pressure on the server side; at the same time, from the response time, we know that it is beneficial for the rapid search and information positioning.
