Dynamic identification of unknown media

A computer readable medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• receiving a request to analyze a media content item, wherein the request comprises at least one of one or more segments of the media content item or digital fingerprints of the one or more segments of the media content item;
• and
• analyzing the media content item to identify copyrighted material contained therein, wherein analyzing the media content item comprises:
• determining an initial interval for selecting segments of the media content item to be analyzed;
• determining a first digital fingerprint of a first segment of the media content item;
• comparing the first digital fingerprint to at least a first subset of a plurality of digital fingerprints of a first plurality of known works to determine whether the first digital fingerprint matches one of the plurality of digital fingerprints of the first plurality of known works;
• determining an updated interval for selecting the segments of the media content item to be analyzed based on whether or not a match was found between the first digital fingerprint and one of the plurality of digital fingerprints of the first plurality of known works;
• determining a second digital fingerprint of a second segment of the media content item, wherein the second segment is separated from the first segment by the updated interval;
• and
• comparing the second digital fingerprint to at least a second subset of the plurality of digital fingerprints of the first plurality of known works to determine whether the second digital fingerprint matches one of the plurality of digital fingerprints of the first plurality of known works.

A system comprising:

• a memory;
• and
• a processing device operatively coupled to the memory, the processing device to:
• receive a request to analyze a media content item, wherein the request comprises at least one of one or more segments of the media content item or digital fingerprints of the one or more segments of the media content item;
• and
• analyze the media content item to identify copyrighted material contained therein, wherein to analyze the media content item the processing device is further to:
• determine an initial interval for selecting segments of the media content item to be analyzed;
• determine a first digital fingerprint of a first segment of the media content item;
• compare the first digital fingerprint to at least a first subset of a plurality of digital fingerprints of a first plurality of known works to determine whether the first digital fingerprint matches one of the plurality of digital fingerprints of the first plurality of known works;
• determine an updated interval for selecting the segments of the media content item to be analyzed based on whether or not a match was found between the first digital fingerprint and one of the plurality of digital fingerprints of the first plurality of known works;
• determine a second digital fingerprint of a second segment of the media content item, wherein the second segment is separated from the first segment by the updated interval;
• and
• compare the second digital fingerprint to at least a second subset of the plurality of digital fingerprints of the first plurality of known works to determine whether the second digital fingerprint matches one of the plurality of digital fingerprints of the first plurality of known works.
