New pending patent applications are published on Thursdays. Both of today's Spotlight Applications concern aspects of digital fingerprinting. Assigned to iHeartMedia, the first application discloses techniques for identifying a broadcast source associated with an unknown fingerprint. Assigned to Boeing, the second application discloses techniques for generating a fingerprint for verification of a reference object.
20180248636, "Identification of broadcast source associated with unknown fingerprint," assigned to iHeartMedia Management Services, Inc.
An end user can sample a radio or television broadcast, generate a user representation of the broadcast sample, and send the user representation to a comparison system, which also receives known representations of content broadcast by multiple different stations. The known representations are stored in a continuous fashion, and represent actually broadcast content. The comparison system identifies the source of the broadcast sample by comparing the user representation to the known representations associated with each of the different stations using a bit count method, such as the Hamming distance. By comparing two representations of content that was actually broadcast, a broadcast source can be identified without requiring the use of watermarks, timestamps, or a database of discreet content items.
20180247157, "Methods and systems for generating a fingerprint for verification of a reference object," assigned to Boeing.
Disclosed herein are methods and systems for generating a fingerprint for verification of a reference object, such as a layer or ply during a composite laminate layup procedure. An exemplary method includes generating a plurality of images of the reference object from a plurality of angles, removing at least one lighting effect from at least one reference image to generate at least one processed image, generating a reference fingerprint for the reference object based on the at least one processed image, generating at least one candidate image of a candidate object, generating a candidate fingerprint for the candidate object based on the at least one candidate image, comparing the candidate fingerprint and the reference fingerprint to determine whether a correlation exists between the candidate fingerprint and the reference fingerprint, and generating an alert based on the comparison of the candidate fingerprint and the reference fingerprint.
