We investigate the inference problems due to functional dependencies (FD) and multi-valued dependencies (hND) in a multilevel relational database (MDB) with attribute and record classification schemes, respectively. For FDs, we show that, to prevent compromise, the security levels of attributes must be assigned by using the knowledge of functional dependencies. Under the assumption that all the attributes in the database have been assigned classification levels according to real world… CONTINUE READING
