The HCI@UBC Seminar series, brought to you by iSchool@UBC, hosts scholars and students working across disciplines on problems related to Human-Computer Interaction. This month’s lecture is by Stuart Schechter, who will review the threat posed by password-guessing and debunk a number of misconceptions about this threat. Schechter will introduce three different witchcraft-free rituals for protecting users from the scourge of guessable passwords and his talk will touch on topics in algorithms, information theory, and human behavior.
