SysPal - System-Guided Pattern Locks for Android

Explore a novel system-guided pattern lock scheme called "SysPal" designed to enhance the security of user-chosen Android screen lock patterns. Learn about the innovative approach that mandates the use of randomly selected points while allowing users the freedom to incorporate them at any position in their pattern. Discover the findings from a large-scale online study involving 1,717 participants, which evaluated the security and usability of three SysPal policies with varying numbers of mandatory points. Gain insights into how SysPal policies can significantly improve pattern security compared to the current Android policy, without compromising memorability. Examine the results of a real-life phone unlock behavior study conducted to assess the practical implications of implementing SysPal on Android devices.
