Patent number: 11468149Abstract: Content screening operations, which can include watermark extraction and the application of content usage enforcement actions, may be organized such that some or all of the operations can be conducted by different devices that are connected via connectors such as HDMI (High-Definition Multimedia Interface (HDMI), analog composite video, DVI (Digital Visual Interface), SDI (Serial Digital Interface), DisplayPort, or networked via Ethernet or wireless. Authentication and encryption methods are disclosed that can be used to establish the trust and secure communication between devices that conduct collaborative content screening. Delegation architecture may be based on ascertained screening capabilities of the sink device wherein the source device verifies that the sink device is capable and trusted to perform partial or whole screening operations delegated by the source.Type: GrantFiled: April 17, 2019Date of Patent: October 11, 2022Assignee: Verance CorporationInventors: Joseph M. Winograd, Jian Zhao, Michael George Kiefer
