Abstract
A system for providing two-factor content protection includes a first device that is enabled with content protection, and a second device that is used to authenticate users of the first device. The first device uses the public key (KPUBLIC) of a public/private key pair belonging to the second device to encrypt its content protection key.

10. A first device enabled with content protection, comprising:
-
a memory; a processor coupled to the memory; and a communication interface coupled to the processor through which the first device is able to communicate with a second device that has a public/private key pair and that is used to authenticate users of the first device, wherein the memory is able to store code, which, when executed by the processor, is arranged to generate a content protection key and to encrypt the content protection key using the public key of the second device. - View Dependent Claims (11, 12, 13)

14. A system for providing content protection, comprising:
-
a first device with content protection capability, wherein the content protection capability, when enabled by a user, is arranged to generate a content protection key used to protect data in the first device; and a second device with a public/private key pair, wherein the public/private key pair is used to encrypt and decrypt the content protection key in order to provide two-factor content protection. - View Dependent Claims (15, 16, 17, 18, 19, 20)
