The Prevalent use of XML highlights an increasing need that publishing XML documents
should meet precise security requirements, without revealing sensitive information to
unauthorized users. We consider data-publishing applications where the publisher specifies
what information is sensitive and should be protected. Hiding the sensitive information is no
enough and the users can use common knowledge (e.g. “all patients in the same ward have
the same disease”) to infer more data, which can cause leakage of sensitive information. We
formulate the process how users can infer data using three types of common XML constraints
and several functional dependencies. We develop a novel paradigm for finding a max partial
document without causing information leakage when we publish several related XML
documents, while allowing publishing as much data as possible. The experiments on real data
sets show that effect of inference on data security, and how the paradigm can prevent leaking
the sensitive information.
