SUMMARY:Whither Challenge Question Authentication? - Mike Just\, Universit
 y of Edinburgh
DTSTART:20090512T151500Z

DESCRIPTION:Questions such as "What is your mother's maiden name?" and "Wh
 at was your first pet's name?" are commonly used today to authenticate use
 rs\, often in support of account recovery when a password is forgotten. De
 spite their ubiquity\, there exists very little published research as to t
 heir efficacy. Some recent\, high profile compromises suggest that they ar
 e not sufficiently secure. Recent research seems to point to a similar con
 clusion. In this talk\, I'll examine some of the recent research into the 
 security and usability of challenge question authentication\, and discuss 
 whether it remains a viable option for user authentication.
