Digital content rendering device and method
First Claim
1. A method for digital content rendering, comprising:
- acquiring a digital content;
acquiring a set of rules associated with the digital content that specify permissions involving at least one level of rendering of the digital content, at least one permission being based on a comparison of a set of specified locations with a sensed location;
determining a sensed location of a content rendering device;
performing comparisons of the sensed location to each of the set of specified locations; and
determining a level of rendering of the digital content in accordance with the set of rules, based on results of the comparisons.

Abstract
A preferred technique includes a digital content rendering device (100) and a method used in the device, including acquiring (305) an encrypted digital content (105), acquiring (305) a set of rules (110) associated with the encrypted digital content that specify permissions involving at least one level of rendering of the digital content that are based on a comparison of a set of specified locations with a sensed location, acquiring (305) an encrypted content key (120), extracting (315) the digital content, determining (330) a sensed location of the content rendering device, performing comparisons (335) of the sensed location to each of the set of specified locations; and determining (340) a level of rendering of the digital content in accordance with the set of rules, based on results of the comparisons.

7. A method for generating encrypted digital content, comprising:
-
generating encrypted digital content by encrypting a digital content with a content key;
encrypting the content key by using a public key of a content rendering device;
generating a set of rules that specify permissions that involve at least one level of rendering of the digital content that are based on a comparison of a set of specified locations with a sensed location;
cryptographically protecting the integrity of a set of rules and the encrypted content; and
associating the cryptographically protected set of rules and the encrypted content key with the encrypted digital content. - View Dependent Claims (8, 9, 10, 11)

12. A digital content rendering device, comprising:
-
a content acquisition area that can acquire a digital content, and a set of rules associated with the digital content that specify permissions involving at least one level of rendering of the digital content, at least one permission being based on a comparison of a set of specified locations with a sensed location; and
a processor and associated instructions that, after the digital content rendering device has acquired a digital content and an associated set of rules, determine a sensed location of the content rendering device, perform comparisons of the sensed location to each of the set of specified locations, and determine a level of rendering of digital content, in accordance with the set of rules, based on results of the comparisons. - View Dependent Claims (13, 14, 15, 16, 17)
