Abstract
Nowadays most of documents are held in digital form. Often document repositories or databases are used to store the info. The info is getting bigger in size and needs to be transferred to partner parties faster. The documents can contain delicate info that not all the actors on the partner side should see and edit. This leads to the need of restricting the actions that a user can do with the document and see in the document. In this work we research possibility to integrate existing technologies to dynamically define forms and their security. For the solution we will introduce a dynamic way to define security on XML documents.
As the info transferred might be high in integrity and confidentiality, we need to keep in mind that despite restricting and giving permissions to user we must also always keep the integrity of the document. In order to fill these needs we will introduce a document structure based Role Based Access Control on each of the document’s info element together with a merging strategy to keep document’s integrity.
We will validate the approach with a case study following a set of business scenarios: check whether our solution can capture all permissions, roles and subjects from the model and whether the document content stays complete when the document is manipulated.
