An Entity of Type: System104377057, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

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.

Property Value
dbo:abstract
  • Una Funcionalidad de Escaneo de Hardware (conocido en inglés como Hardware Functionality Scan) es una función levada a cabo con el fin de verificar que un determinado dispositivo es realmente lo que dice ser. Es patentado por Microsoft.​ Algunos sistemas operativos sólo envían copias de contenido protegido, tales como películas, a un dispositivo de salida, como es la pantalla, si el dispositivo es capaz de proteger el contenido en caso de ser aprovechado por uno formato desprotegido. Este mecanismo puede ser eludido por dejar hardware falso que dice ser un dispositivo de confianza. HFS impide que el dispositivo realice ciertas tareas que son difíciles de emular. (es)
