New patents are issued by the USPTO on Tuesdays. Both of today's Spotlight Patents concern aspects of digital fingerprinting. Assigned to Robert Bosch (DE), the first of today's patents addresses techniques for device pairing with audio fingerprint encodings.
9,779,742, "Device pairing with audio fingerprint encodings," assigned to Robert Bosch GmbH
A device and/or method for allowing authorization of computing device association using human-perceptible signals includes forming an association between a computing device and a further computing device. The computing device computes a fingerprint of a common key derived during the forming of the association and emits a first audio stimuli based upon the computed fingerprint. The first audio stimuli is at least one octave number apart from a second audio stimuli of the further computing device emitted by the further computing device based upon the common key.
9,781,377, "Recording and playback system based on multimedia content fingerprints," assigned to TiVo.
A method for recording media content based on media content fingerprints is described. A media device records content received in a content stream from a scheduled start time of a media content to a scheduled end time of the media content to create a content recording. The media device derives one or more fingerprints from the content recording. A fingerprint database is queried with the one or more fingerprints to determine that a first portion of the content recording comprises an advertisement and a second portion of the content recording comprises the media content. In response to a request to play the content recording, starting playback of the content recording at the beginning of the second portion of the content recording.
