Windows 10 mobile devices, Surface Laptops, and several other 3rd parties integrate an Intel Realsense 3D camera.

Windows Hello extends this 3D camera to support user authentication.

  • What security parameters are used to describe the relative security of this authentication? (for example, fingerprint readers use quantity of points to determine the integrity of the scan)

  • What other relevant information is useful for comparing this biometric authentication

    Since you cannot change biometric parameters (e.g. your face!), I personally think that biometric logins can only ever be a convenience feature not really a security one. Certainly not a high-security feature. Well managed multi-factor authentication will always be stronger. However, for many use cases, it is going to be "good enough" Commented Sep 12, 2016 at 9:12
  • @JulianKnight This question is regarding the technical quality of the biometric data received. I'm looking for a summary of data points, class, resolution, vertices, etc that are used for this feature. Commented Sep 12, 2016 at 14:23
  • ... also not authentication is the same. Windows Hello implies "something you have", which is the computer with the non-transferrable hello data. Akin to the thumbprint sensor on many devices. You do have valid points though. Commented Sep 12, 2016 at 14:25
  • "This question is regarding" - Yes, that's why that is a comment and not an answer. ;-) Commented Sep 12, 2016 at 14:26
  • Is the hello data non-transferable? I've not checked whether it syncs to other machines along with much other data. Good point though. Commented Sep 12, 2016 at 14:27

According to Microsoft's website, there are 3 measurements that represent the accuracy of Windows Hello's facial recognition, which are: False Positives; True Positives; and False Negatives. These are explained in the quote below

Microsoft represents the accuracy of Windows Hello face in three main measures, which are: False Positives, True Positives, and False Negatives.

False positives:

Also called False Acceptance Rate, represents the likelihood a random user who obtains access to your device will be recognized as you. This number should be as low as possible.

With windows 10, the results are less than 0.001% or 1/100,000 FAR (False Acceptance Rate)

True Positives:

The True Positive rate represents the likelihood a user will be correctly matched to their profile each time they are registered by the camera This number should be high

The results with windows 10 are greater than 95% with a single enrolled user

False negatives:

Represents the likelihood a user is not matched to their enrolled profile. This number should be low.

The results with Windows 10 are less than 5% with a single enrolled user.

    this is a generic description of biometrics in general, none of this answers the question
