Appl. No.:

13/964843

Assignee:

Intertrust Technologies Corporation - Sunnyvale CA

International Classification:

G06F 21/10

US Classification:

726 26

Abstract:

Systems and methods are provided for protecting electronic content from the time it is packaged through the time it is experienced by an end user. Protection against content misuse is accomplished using a combination of encryption, watermark screening, detection of invalid content processing software and hardware, and/or detection of invalid content flows. Encryption protects the secrecy of content while it is being transferred or stored. Watermark screening protects against the unauthorized use of content. Watermark screening is provided by invoking a filter module to examine content for the presence of a watermark before the content is delivered to output hardware or software. The filter module is operable to prevent delivery of the content to the output hardware or software if it detects a predefined protection mark. Invalid content processing software is detected by a monitoring mechanism that validates the software involved in processing protected electronic content. Invalid content flows can be detected by scanning the information passed across system interfaces for the attempted transfer of bit patterns that were released from an application and/or a piece of content management software.
