Easy to Draw, but Hard to Trace?: On the Observability of Grid-based (Un)lock Patterns
CHI '15: Proceedings of the 33rd Annual ACM Conference on Human Factors in Computing SystemsPages 2339–2342https://doi.org/10.1145/2702123.2702202We performed a systematic evaluation of the shoulder surfing susceptibility of the Android pattern (un)lock. The results of an online study (n=298) enabled us to quantify the influence of pattern length, line visibility, number of knight moves, number ...
