Tuesdays the PTO issues new patents. Both of today's Spotlight Patents concern aspects of digital fingerprinting. Assigned to Cognitive Networks, the first patent addresses techniques for real-time television ad detection using an automated content recognition database. Assigned to IBM, the second patent addresses techniques for generating and utilizing a data fingerprint to enable analysis of previously available data.
8,930,980, "Systems and methods for real-time television ad detection using an automated content recognition database," assigned to Cognitive Networks, Inc.
A system and method for the automated real-time detection and processing of commercial messages, public service announcements or similar short-duration, repeated TV programming segments occurring in one or more broadcast video steams is described. A process is utilized that identifies possible commercial segments by identifying discrete video segments that have specific short durations among other attributes. Video segments that appear to have these characteristics are considered likely to be television commercials, promotions, or public service announcements and are stored in a TV Ad database which is separate from the primary television content database. Incoming video from a plurality of television programming sources is process into fingerprints and placed in a master TV content database. At the same time, said incoming programming is tested for matches in a TV ad database. If a match is found, then the presumed TV ad is removed from the master content database.
8,930,325, "Generating and utilizing a data fingerprint to enable analysis of previously available data," assigned to IBM.
According to one embodiment of the present invention, a system analyzes data in response to detecting occurrence of an event, and includes a computer system including at least one processor. The system maps fields between the data and a fingerprint definition identifying relevant fields of the data to produce a fingerprint for the data. The data is deleted after occurrence of the event. The produced fingerprint is stored in a data repository, and retrieved in response to detection of the event occurrence after the data has been deleted. The system analyzes the retrieved fingerprint to evaluate an impact of the event on corresponding deleted data. Embodiments of the present invention further include a method and computer program product for analyzing data in response to detecting occurrence of an event in substantially the same manner described above.
