In this paper, the authors determined the degree to which keystroke performance results obtainable on mobile devices exceed those obtainable on hardware keyboards. The biometric equal error rates on three sets of Smartphone touchscreen data - the keystroke timing data similar to that available on hardware keyboards, the non-timing touchscreen data not available on hardware keyboards, and all the touchscreen data combined - were 10.5%, 3.5%, 2.8%, respectively. These results show that considerably greater biometric value is available from Smartphone touchscreen data compared to that from hardware keyboards.
