ABSTRACT:

Role based access control is well accepted as the standard best practice for access control within applications and organizations. Role engineering, the task of defining roles and associating permissions to them, is essential to realize the full benefits of the role-based access control paradigm. The essential question is how to devise a complete and correct set of roles; this depends on how you define goodness/interestingness. (When is a role good/interesting?) We formulate the role mining problem (RMP) as a Boolean matrix decomposition problem and introduce different variants of the RMP that have pragmatic implications. Formulating the problem as a Boolean matrix decomposition makes our results applicable to several other domains, including text mining, recommender systems, and knowledge discovery from databases.
