9,026,796, "Virtual world embedded security watermarking," assigned to IBM.
A method, apparatus, and program product are provided for using watermarks to embed security features on avatars in a virtual world. A watermark engine receives security information for an avatar in a virtual world. The watermark engine creates a watermark for the avatar using the security information and associates the watermark with the avatar. The watermark may comprise at least one of: security preferences for the avatar, contact information for an owner of the avatar, and graphical information to cause alteration of the avatar when the avatar is recorded.
9,021,514, "Monitoring device for capturing audience research data," assigned to GFK Telecontrol AG (CH)
A monitoring device (1) comprising a basic set of audience research data retrieval units (7, 9) which are compatible with a broad range of AV appliances reproducing AV contents like TV sets (3). The data retrieval units are a audio watermark retrieval unit (9) and an audio signal sampling unit (7). For easy adaptation to particular AV installation, the monitoring device (1) is provided with internal and external connectors so that specialized modules can be integrated.
