Content relies on one biometric characteristic

Rule

Where ICT uses biological characteristics, it MUST NOT rely on the use of a particular biological characteristic as the only means of user identification or for control of ICT.

Background

If a person trying to access content does not have a particular biometric characteristic (for example, a fingerprint), they may be blocked from accessing the content if that characteristic is the only option available. Providing alternative methods to access content increases the chance everyone will be successful. Alternative means of user identification ICT could be non-biometric or biometric. Biometric methods based on dissimilar biological characteristics increase the likelihood that individuals with disabilities possess at least one of the specified biological characteristics. Examples of dissimilar biological characteristics are fingerprints, eye retinal patterns, voice, and face.

How to Fix

To fix this issue:

1. Provide an alternate method to access content or identify the user that does not rely on biometrics, OR

2. Ensure that more than one dissimilar biometric characteristic can be used. Biometric methods based on dissimilar biological characteristics increase the likelihood that individuals with disabilities possess at least one of the specified biological characteristics. Examples of dissimilar biological characteristics are fingerprints, eye retinal patterns, voice, and face.
