翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Hardware functionality scan ： ウィキペディア英語版 Hardware functionality scan A hardware functionality scan (HFS) is conducted in order to verify that a certain device is really what it claims to be. It is patented by Microsoft. Some operating systems only send copy protected content, such as movies, to an output device, such as the screen, if that device is able to protect the content from being tapped in an unprotected format. This mechanism can be circumvented by letting fake hardware claiming to be a trusted device. HFS prevents this by letting the device perform certain tasks which are hard to emulate. ==Problems== In order to support open-source drivers, a hardware manufacturer has to reveal some details about their product, but HFS requires this information to be kept secret. The problem with generic drivers is that the HFS requires individual drivers for each variant of a product to make them distinguishable, drivers have to account for implementation details instead of using abstract functionality models. 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 they have to pay a royalty to its respective inventor. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hardware functionality scan」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
