Ontology is a system of belief that reflects an interpretation by an individual about what constitutes a fact.Authentication ontology , explores the use of a automated ontological engineering, corpus analysis and natural language.. Authentication mainly focused in authorization, data integrity and confidentiality,.

Best Wishes..

Jahid Siraz Seems to me like you're confusing ontology with epistemology, which is what both the people you quoted were all about. Incidentally, neither of them did any work related to authentication - the way the security industry understands authentication.
