Inherence Factor (Something You Are)

What is Inherence Factor (Something You Are)?

Inherence Factor (Something You Are)An authentication factor based on a biometric characteristic of the user, such as a fingerprint, face, iris, voice or typing rhythm.


The inherence factor proves identity by something the user is. It is measured biometrically: fingerprint, face geometry, iris pattern, palm vein, voice, signature dynamics or behavioural biometrics such as typing cadence. Modern devices implement inherence with sensors plus secure enclaves (Apple Face ID/Touch ID, Windows Hello, Android BiometricPrompt) that compare a captured sample against a template stored locally on a TPM, Titan or Secure Enclave chip. Standards such as ISO/IEC 19794 and 30107 define template formats and presentation-attack detection. Inherence is convenient and resistant to sharing, but it is irrevocable: leaked biometric data cannot be reset like a password.

Examples

  1. 01

    Unlocking an iPhone with Face ID instead of a passcode.

  2. 02

    Authenticating into an enterprise laptop using Windows Hello fingerprint.
