Our FAQs series
We decided to start a series of blog posts to cover popular topics of interest around how our proprietary AI typing biometrics technology works. We want to ensure our customers feel confident they benefit from the most widely available, up to date typing biometrics technology worldwide.
If your typing pattern changes, can you still be authenticated?
The external environment can easily influence biometric authentication. For example, voice recognition can fail due to noisy interferences in the background, wet fingerprints can’t unlock a smartphone, and face recognition is affected by poor lighting, unclear expression, or pose.
There are three things to take into consideration when using typing biometrics for authentication:
A person’s typing pattern can change to some degree over time as they learn to type faster and more accurately, for example. To address change in typing behavior, you can choose to save new typing patterns to your profile. This way, you will have an up-to-date “picture” of your user’s typing behavior, which can be used for proper authentication.
On rare occasions, the typing pattern of a user changes for good (e.g., permanent hand damage). In such a scenario, previously enrolled patterns have to be deleted, requiring a profile reset for the concerned user. TypingDNA’s API allows for user profile reset. This can be done in the background by developers, or it can be done freely by the end-users if this is the policy of the enterprise using the solution.
There are situations when the typing behavior of a user changes temporarily for reasons such as breaking a hand, typing on a different keyboard, or even having too much coffee to drink. To ensure robust authentication, we recommend at least one additional security factor, to allow the user to log in until the pattern gets back to normal (e.g., a broken hand heals).
