Apparatus and methods are described for detecting sharing of electronic or online accounts based on grouping of data samples that include keyboard input timing factors and optionally secondary factors. The data samples can be received from various computers having various keyboards of a certain type and may be input by more than one user. The data samples are grouped based on distances and ratios of mathematical combinations of distances between input timing of key events such as dwell…

Embodiments of the invention relate to collecting keystroke timing data of samples of a phrase input by a user on an input device during different user sessions, and creating a biometric user template based on the timing data collected during the different sessions. Once a sufficient number of samples are collected, the template may be used to authenticate the user.
