On Thursdays the USPTO publshes new patent applications. Both of today's Spotlight Applications concern aspects of digital fingerprinting. Assigned to TVU Networks, the first application discloses techniques for fingerprint-based copyright protection of real-time content. Assigned to Uniloc, the second application discloses techniques for determining authorization to operate licensed software based on a client device fingerprint.
20110004944, "Methods and systems for fingerprint-based copyright protection of real-time content," assigned to TVU Networks Corporation.
The present invention provides methods and systems for fingerprint-based copyright protection of real-time content. A first fingerprint is provided for content from a fingerprint ingesting device to a central server. The first fingerprint is associated with one or more business rules for the content at the central server. At least one of (a) a second fingerprint is provided for the content from a broadcast device to the central server, and (b) a third fingerprint is provided for the content from a receiving device to the central server. The first fingerprint is then compared with the at least one of the second and third fingerprints at the central server. One or more corresponding business rules may then be determined for the content based on the comparing.
20100333213, "Systems and Methods for Determining Authorization to Operate Licensed Software Based on a Client Device Fingerprint," assigned to Uniloc USA.
Methods and systems disclosed herein may be used to determine if licensed software has been previously installed or used on a device by monitoring an identifier associated with the device on which the licensed software is to be installed or used. Prior to operation of licensed software, a client device requires authorization from a license server. The license server may retrieve a unique identifying device fingerprint from the client device to authorize installation of the software based on a probabilistic comparison of the identifier with stored device identifiers subject to a license. If the comparison yields a match and if total instances of retrieval of the retrieved device fingerprint does not exceed licensed rights, the authorization is granted.
