More on PassPoints!
Studies on visual attention and eye movements show that most images contain a few portions that humans typically focus on - so-called image “hotspots”.  This study seeks to device a model that enables the prediction of the entropy in a given image.  Such a model would enable the design of automatic “dictionary” attacks [...]

Reducing Shoulder-surfing by Using Gaze-based Password Entry

Thursday, July 19th, 2007

http://cups.cs.cmu.edu/soups/2007/proceedings/p13_kumar.pdf
Passwords are generally entered through keyboard, mouse, touch screen, or keypad.  All of these are subject to shoulder surfing.  The paper proposes using a gaze-based entry method rather than actually having to enter the password on a keypad, which avoids both shoulder-surfing and possibly keystroke logging.

This paper seeks to survey how companies in different sectors actually handle security incidents.  Thus far they’ve had trouble getting input from outside of academia.  They analyzed their results using grounded theory.  Their main findings were that handling of security incidents is seldom handled by a single individual, but rather is typically handled by a [...]

Anti-Phishing Phil: The Design and Evaluation of a Game That Teaches People Not to Fall for Phish

Thursday, July 19th, 2007

http://cups.cs.cmu.edu/soups/2007/proceedings/p88_sheng.pdf
Researches proposed an on-line game intended to teach users about phishing.  Users were shown 10 URLs before training and another 10 after, and were trained either using the game or other methods of anti-phishing training.  The results suggested that people learned about phishing better through using this game than through traditional phishing training techniques.
The paper [...]
