Stanford Security Seminar

Paul Van Oorschot

Abstract:

The past ten years have seen a flood of proposed new image-based password schemes -- graphical passwords -- in an attempt to address long-standing problems with traditional text passwords. We provide a selective review of research in this area, including discussion of security and usability analysis of existing proposals, design and analysis of new proposals, and the value of user studies. Our goal is to design better password systems through lessons learned from graphical password systems; and more broadly, to extract principles of general use in the emerging field of security and usability
