New patents are issued by the USPTO on Tuesdays. Today's Spotlight Patents concern aspects of digital watermarking and digital fingerprinting. Assigned to MorphoTrust USA, the first patent addresses a digital identification document including a digital biometric of the person and a digital watermark, the digital watermark encoding personally identifiable information of the person. Assigned to Cisco, the second patent addresses techniques for multi-blend [digital] fingerprinting.
10,282,802, "Digital identification document," assigned to MorphoTrust USA, LLC.
Some implementations may include a computer-assisted method for authenticating a person at a point of service, the method including: receiving a digital identification document including a digital biometric of the person and a digital watermark, the digital watermark encoding personally identifiable information of the person; retrieving the digital watermark from the received digital identification document; extracting the personally identifiable information from the retrieved digital watermark; and authenticating the person identified by the digital biometric based on the retrieved digital watermark.
10,282,618, "Multi-blend fingerprinting," assigned to Cisco.
Multi-blend fingerprinting may be detected. First, a video sample may be received. Next, frames of the received video sample may be step iteratively through until a probability value corresponding to a current frame indicates a match. Deciding that the probability value indicates the match may comprise creating an augmented frame, determining the probability value corresponding to the created augmented frame, and determining that the probability value indicates the match. Then a fingerprint from the created augmented frame may be extracted.
