Abstract

A multimedia output device having embedded encryption functionality enables the outputting of content in an encrypted form. The multimedia output device receives the content to be encrypted, encrypts the content, and generates an electronic output of the encrypted content. The multimedia output device also generates an associated paper output that provides information about the decryption, such as a key, an identification of the electronic output of the encrypted content, and optionally a description of the contents of the content encrypted.

Claims

1. A multimedia output device for outputting content in an encrypted form, the multimedia output device comprising:

an interface for receiving the content from an external source;

an encryption module, coupled to the interface to receive the content to be encrypted and to encrypt the content;

a first output system in communication with the encryption module to receive the encrypted content and produce a first output of the encrypted content.
