Abstract

Due to the increasing use of mobile phones at the expense of computers and notebooks, coupled with the absence of built-in sensors in these devices, the interoperability of passwords using keystroke dynamics on these two types of keyboards becomes relevant. For this analysis, a quantitative methodology with experimental elements was used, employing the extraction of mathematical and graphical data in addition to classification methods. Consequently, the results demonstrate that the interval behaviors of the touchscreen dataset are in line with previously proven scientific results. Therefore, it is suggested that interoperability between the two types of keyboards is possible, but with an interval equalization process.
