dc.description.abstract
In this master thesis, we propose a security improvement for traditional unlock patterns as found in modern off-the-shelf smartphones. With our StopUnlock Patterns we propose to add a stop component which lets users define nodes where they deliberately stop for a limited amount of time before swiping to the next node of their unlock pattern. We argue that this stop component lets users select higher entropy patterns with only a minimal impact on usability metrics (such as authentication time and error rate) in comparison to simply increasing the length of the pattern. To evaluate StopUnlock Patterns, we conducted a lab study (n=40), a field study (n=14) and a security evaluation. Our findings suggest that StopUnlock Patterns (i) are easy to use, (ii) are memorable, and (iii) improve security.
