On Thursdays the USPTO publishes new pending patent applications. Today's Spotlight Applications concern aspects of digital fingerprinting. Assigned to Technology, Patents & Licensing, Inc., the first application discloses techniques for video entity recognition in compressed digital video streams. The second application discloses techniques for transaction assessment and/or authentication.
20100290667, "Video entity recognition in compressed digital video streams," assigned to Technology, Patents & Licensing, Inc.
A method and system for detection of video segments in compressed digital video streams is presented. The compressed digital video stream is examine to determine synchronization points, and the compressed video signal is analyzed following detection of the synchronization points to create video fingerprints that are subsequently compared against a library of stored fingerprints.
20100293094, "Transaction assessment and/or authentication," no assignee given.
Systems and methods for assessing and authenticating transactions are disclosed. Some exemplary embodiments may authenticate transactions based at least in part on a comparison of a newly obtained electronic signature associated with a user with a previously obtained electronic signature associated with the user, where a payment instrument presented for use in the transaction is also associated with the user. Exemplary electronic signatures may comprise any information which may identify the user, such as browser fingerprints, computer fingerprints, IP addresses, geographic IP location information, information associated with a payment, and/or a typing patterns.
