New pending patent applications are published by the USPTO on Thursdays. Both of today's Spotlight Applications concern aspects of digital fingerprinting. Assigned to ESL Laboratory, the first application discloses techniques for protecting sensitive documents. Assigned to Viaccess (FR), the second application discloses techniques for identifying a content being displayed on a screen.
20170085376, "Document meta-data repository," assigned to ESL Laboratory LLC
A computer based method of protecting sensitive documents is provided, the method comprising identifying a first document, generating a registration key associated with the first document, identifying a second document, generating a production key associated with the second document, and producing an alert if a segment of the production key is identical to a segment of the registration key. For example, the registration key may comprise a digital fingerprint and registration metadata and the production key may comprise a digital fingerprint and production metadata, and the method may produce an alert of the digital fingerprint of the production key matches the digital fingerprint of the registration key.
20170085946, "Method and device for identifying a content being displayed on a screen," assigned to Viaccess (FR).
A method for identifying, via a first terminal, a content being displayed on a screen of a second terminal located in the same space as the first terminal includes collecting with the first terminal the luminosity produced in the space by the screen of the second terminal, generating with the first terminal at least one digital fingerprint depending on the collected luminosity, comparing the fingerprint generated to a reference fingerprint stored beforehand in a memory, and identifying the content depending on the result of the comparison.
