Say Hello to “Windows Hello”

What is Windows Hello? Want to secure your Pc without a password? Say hello to Windows hello (yes, the pun is Intentional)

What is Windows Hello?

Windows Hello gives Windows 10 users an alternative way to log into their devices and applications using a fingerprint, iris scan or facial recognition.

Windows Hello is a more personal way to sign in to your Windows 10 devices with just a look or a touch. You’ll get enterprise-grade security without having to type in a password.

What are the System Requirements for Windows Hello?

OS Requirements

Windows Hello is currently only supported on windows 10.

Biometric

Windows Hello requires a compatible 3D depth camera and a fingerprint reader with the following specifications:

Fingerprint reader

Large Area sensors (a sensor matrix of 160 x160 Pixels or more at a dpi of 320 or greater):

FAR < 0.001%.

Effective, real world FRR with anti-spoofing or liveness detection <10%.

presentation attack defence measures are a requirement.

Small Area sensors (a sensor matrix of less than 160×160 at a dpi of 320 or greater):

FAR < 0.002%.

Effective, real world FRR with antispoofing or liveness detection <10%.

Presentation attack defense measures are a requirement.

Swipe sensors:

FAR < 0.002%.

Effective, real world FRR with anti-spoofing or liveness detection <10%.

Anti-spoofing measures are a requirement.

Facial feature recognition

FAR < 0.001%.

TAR > 95%.

If you don’t understand what the abbreviations mean(FAR, TAR, e.t.c) I got you:

Definition of Terms

  • False Accept Rate (FAR): Represents the number of instances that a biometric identification solution verifies an unauthorized person. This is normally represented as a ratio of number of instances in a given population size, for example 1 in 100,000. This can also be represented as a percentage of occurrence, for example, 0.001 percent. This measurement is heavily considered the most important with regards to the security of the biometric algorithm.
  • True Accept Rate (TAR): Represents the number of instances a biometric identification solution verifies the authorized user correctly. This is normally represented as a percentage. It is always held that the sum of the True Accept Rate and False Reject Rate is 1.
  • False Reject Rate (FRR): Represents the number of instances a biometric identification solution fails to verify an authorized user correctly. Usually represented as a percentage, the sum of the True Accept Rate and False Reject Rate is 1.
  • Confidence: The confidence in a claimed FAR represents the robustness of the analysis performed in verifying a claimed FAR. Depending on the target or claimed FAR and the importance of the taget use case, confidence levels can be varied.
  • Biometric sample: This refers to the complete biometric sample required to perform a verification operation. For example, a single fingerprint is required to perform a verification.
  • Biometric spoof: This refers to a synthetic replica of a biometric sample.

How to Set Up Windows Hello

Select the Start  button, then select Settings > Accounts  > Sign-in options  to set up Windows Hello. Under Windows Hello , you’ll see options for face, fingerprint, or iris if your PC has a fingerprint reader or a camera that supports it. Once you’re set up, you’ll be able to sign in with your finger print, iris scan or face.
