A '''Hardware Functionality Scan''' (HFS) is conducted in order to verify that a certain device is really what it claims to be. It's patented by [[Microsoft]].

Line 6 ⟶ 8:

* '''open-soure drivers''': In order support open-source drivers, a hardware manufacturer has to reveal some details about their product, but HFS requires these information to be kept secret.

* '''generic drivers''': The HFS requires indiviudal drivers for each variant of a product, to make them distinguishable: drivers have to account for implementation details instead of using abstract functionality models.

* '''trusted hardware''': A hardware manufacturer has to have his product's HFS fingerprint listed in the database of trusted hardware, in order to make it work under newer Windows operating systems. Thus, Microsoft dictates the conditions under which a device is accepted. The manufacturer may be required to implement certain DRM-features for which he has to pay a royalty to it'sits respective inventor.
