Models of Knowledge-Based Authentication
This is from a presentation that I did at NIST. This was at a symposium on knowledge-based authentication (KBA). The slides aren't really much to look because it was more of a conversation than a presentation... but it was very interesting to participate in the symposium. This was based upon some work I had been doing at MITRE on KBA for the Pay.gov program at the Treasury's Financial Management Service. Download a PDF of the slides [here].
