Hvis din Windows 10-pc understøtter Windows Hello^{(Windows 10 PC supports Windows Hello)} , og du har konfigureret ansigtsgenkendelse , kan du aktivere forbedret anti-spoofing. Windows Hello er en biometribaseret teknologi, der gør det muligt for brugere at autentificere deres identitet for at få adgang til deres enheder, apps, netværk osv. ved hjælp af fingeraftryk, ansigtsgenkendelse eller irisscanning. Nu fungerer ansigtsgenkendelse i Windows 10 godt, men den kan ikke skelne mellem et billede af dit ansigt inde i din mobil eller det faktiske brugeransigt.

Den potentielle trussel på grund af dette problem er, at nogen med dit billede kan låse din enhed op ved at bruge deres mobil. For at overvinde denne vanskelighed træder anti-spoofing-teknologien i aktion, og når du først har aktiveret anti-spoofing for Windows Hello Face Authentication , kan et billede af den autentiske bruger ikke bruges til at logge ind på pc'en.

Aktiver forbedret anti-spoofing^{(Enhanced Anti-Spoofing)} for Hello Face Authentication

Forbedret^(Enhanced) anti-spoofing til Windows Hello - ansigtsgodkendelse er ikke påkrævet på ikke-administrerede enheder, og du skal være logget på som administrator for at aktivere eller deaktivere forbedret anti-spoofing. At gøre dette:

Åbn den lokale gruppepolitikeditor, og gå til den venstre rude i den lokale gruppepolitikeditor^{(Local Group Policy Editor)} , naviger til følgende placering:

Computer Configuration > Administrative Templates > Windows Components > Biometrics > Facial Features.

Dobbeltklik på Konfigurer forbedret anti-spoofing-^{(Configure enhanced anti-spoofing)} politik i den højre rude af Ansigtstræk^{(Facial Features)} i Local Group Policy Editor for at redigere den.

This policy setting determines whether enhanced anti-spoofing is required for Windows Hello face authentication.

If you enable this setting, Windows requires all users on managed devices to use enhanced anti-spoofing for Windows Hello face authentication. This disables Windows Hello face authentication on devices that do not support enhanced anti-spoofing.

If you disable or don’t configure this setting, Windows doesn’t require enhanced anti-spoofing for Windows Hello face authentication.

Note that enhanced anti-spoofing for Windows Hello face authentication is not required on unmanaged devices.

Som angivet i skærmbilledet ovenfor, gør følgende;

For at deaktivere forbedret anti-spoofing for Windows Hello Face Authentication^{(To Disable Enhanced Anti-Spoofing for Windows Hello Face Authentication)}

• Klik på alternativknappen for Ikke konfigureret^{(Not Configured)} eller deaktiveret^(Disabled) , klik på OK.

For at aktivere forbedret anti-spoofing til Windows Hello-ansigtsgodkendelse^{(To Enable Enhanced Anti-Spoofing for Windows Hello Face Authentification)}

• Klik på alternativknappen Aktiveret^(Enabled) , klik på OK .

Du kan nu afslutte Group Policy Editor og genstarte dit system.

Den ovenfor beskrevne procedure virker ikke på Windows 10 Home Edition , fordi Group Policy Editor ikke er indbygget i Home - udgaven. Men for at udføre den samme procedure på Home - udgaven skal du installere PolicyPlus ^{(install PolicyPlus)}. Når du har tilføjet værktøjet, kan du nu følge de samme trin som beskrevet ovenfor for at aktivere Enhanced Anti-Spoofing til Windows 10 Home .

Enable Enhanced Anti-Spoofing in Windows 10 Hello Face Authentication

Іf your Windows 10 PC supports Windows Hello and you have set up facial recognition, then you can enable enhanced anti-spoofing. Windows Hello is a biometrics-based technology that enables users to authenticate their identity in order to access their devices, apps, networks, etc using fingerprint, face recognition, or iris scan. Now face detection in Windows 10 works well, but it can’t differentiate between a photo of your face inside your mobile or the actual user face.

The potential threat because of this issue is that someone with your photo could unlock your device by using their mobile. To overcome this difficulty, the anti-spoofing technology comes into action, and once you have enabled the anti-spoofing for Windows Hello Face Authentication, a photo of the authentic user cannot be used to login to the PC.

Enable Enhanced Anti-Spoofing for Hello Face Authentication

Enhanced anti-spoofing for Windows Hello face authentication is not required on unmanaged devices and you must be signed in as an administrator to enable or disable enhanced anti-spoofing. To do this:

Open the Local Group Policy Editor and on the left pane of Local Group Policy Editor, navigate to the following location:

Computer Configuration > Administrative Templates > Windows Components > Biometrics > Facial Features.

On the right pane of Facial Features in Local Group Policy Editor, double-click Configure enhanced anti-spoofing policy to edit it.

This policy setting determines whether enhanced anti-spoofing is required for Windows Hello face authentication.

If you enable this setting, Windows requires all users on managed devices to use enhanced anti-spoofing for Windows Hello face authentication. This disables Windows Hello face authentication on devices that do not support enhanced anti-spoofing.

If you disable or don’t configure this setting, Windows doesn’t require enhanced anti-spoofing for Windows Hello face authentication.

Note that enhanced anti-spoofing for Windows Hello face authentication is not required on unmanaged devices.

As indicated in the screenshot above, do the following;

To Disable Enhanced Anti-Spoofing for Windows Hello Face Authentication

• Click the radio button for Not Configured or Disabled, click OK.

To Enable Enhanced Anti-Spoofing for Windows Hello Face Authentification

• Click the radio button Enabled, click OK.

You can now exit Group Policy Editor and restart your system.

The procedure described above won’t work on Windows 10 Home Edition because Group Policy Editor is not built into Home edition. However, to carry out the same procedure on Home edition, install PolicyPlus. Once you have added the utility, you can now follow the same steps as described above to enable Enhanced Anti-Spoofing for Windows 10 Home.
