Abstract
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.
Claims28
A method comprising:
- collecting keystroke timing data of a plurality of samples of a phrase input by a first user on an input device during a plurality of different sessions by the first user;
- and
- creating a biometric user template based on the timing data collected during the plurality of different sessions by the first user, wherein the plurality of different sessions by the first user are distinguished by each session being associated with the user being at a different location.
A method comprising:
- collecting first keystroke timing data of a first plurality of samples of a phrase input by a first user on at least one input device during a first plurality of sessions;
- creating incomplete biometric user template data based on the first keystroke timing data, wherein the incomplete template is insufficient to provide bio-authentication of the first user;
- then
- collecting subsequent second keystroke timing data of at least one additional sample of the phrase input by the first user on an input device during a second different session;
- modifying the incomplete biometric user template data using the subsequent keystroke timing data to create a complete biometric user template that is sufficient to provide bio-authentication of the first user, wherein the plurality of different sessions by the first user are distinguished by each session being associated with the user being at a different location.
2 more elements
A non-transitory computer-readable medium storing data and instructions to cause a programmable processor to perform operations comprising:
- collecting keystroke timing data of a plurality of samples of a phrase input by a first user on an input device during a plurality sessions;
- and
- creating a biometric user template based on the timing data collected during the plurality of sessions, wherein the plurality of different sessions by the first user are distinguished by each session being associated with the user being at a different location.
