Tell Me Who You Are and I Will Tell You Your Lock Pattern

Explore the security implications of Android lock patterns in this 28-minute conference talk from BSidesLV 2015. Delve into Marte Løge's research on the predictability of user-chosen lock patterns, examining factors such as visual complexity, handedness, and common sequences. Learn about the number of possible combinations, average pattern length, and the surprising correlations between user demographics and their chosen patterns. Gain insights into the survey methodology used and discover potential areas for future research in mobile device security.
