Abstract
Embodiments of this application disclose a video detection method and a server. The method includes: obtaining first video data to be detected; decoding the first video data, to obtain audio data of the first video data; analyzing and identifying the audio data, to obtain audio fingerprint data corresponding to the audio data; querying an audio fingerprint library; obtaining a video label and a time parameter corresponding to the audio data when the audio fingerprint library comprises the audio fingerprint data; querying a video copyright library, to obtain a first picture that is corresponding to the video label and that satisfies the time parameter, and extracting a second picture that is in the first video data and that satisfies the time parameter; separately extracting a first feature parameter of the first picture and a second feature parameter of the second picture; and comparing the first feature parameter with the second feature parameter, and determining, based on a comparison result, whether the first video data is consistent with a video in the video copyright library.
20190087889, "System and method adapted to facilitate sale of digital images while preventing theft thereof," assigned to Waldo Photos, Inc.
Abstract
The present invention facilitates secure display and sale of copyright protected images, by showing alternate reciprocal images, with complementary obstructed/degraded and clearly visible areas. System components include server machines and/or computer terminals with a screen or other display mechanism. The system may be connected through a communications network or it may be self-contained on a stand-alone, specialized computer system. System components further include non-transitory computer-readable media containing a database of images. The system creates and displays alternate reciprocal images showing blockades covering faces, patterns or objects of interest in a first image and showing the same faces, patterns or objects shown as clearly visible with all surroundings having degraded resolution or blur. Users are provided an opportunity to purchase the image and a clean copy of the image is delivered to the user upon completion of a purchase transaction.
