1. A method for authorizing transfer of a candidate content against a data store storing extracted feature data for reference content, comprising:
- extracting first feature data from the candidate content, wherein said extracting comprises apportioning the candidate content into plural sub-regions and extracting feature data from the plural sub-regions, and wherein each sub-region is at most ten percent of the candidate content; and
sending extracted feature data to a sever configured to perform selecting reference feature data from the data store, comparing extracted feature data with the reference feature data, and determining an authorization for transfer of the candidate content based at least in part on the comparing.

Abstract
Identifying content and authorizing sharing thereof based at least in part on extracting feature data from content to be shared and comparing this extracted feature data against a database of extracted feature data for various reference content. When the content to be shared is matched to reference content in the database, sharing may be simply rejected, or rights associated with the reference content may be inspected to facilitate determining authorization.

10. A method for authorizing transfer of a candidate content against a data storage storing extracted feature data for reference content, comprising:
-
receiving feature data for the candidate content comprising extracted feature data for a portion of the candidate content and extracted feature data for a first portion of the reference content;
selecting first reference feature data from the data storage, the first reference feature data comprises extracted feature data for a first portion of the reference content;
first comparing the received feature data to the first reference feature data;
authorizing transfer of the candidate content based at least in part on the first comparing;
determining a non-match between the received feature data and the first reference feature data;
selecting second reference feature data from the data storage comprising extracted feature data for a second portion of the reference content; and
second comparing the second reference content to the received feature data; and
performing a sliding window comparison to match the received feature data against the reference content;
wherein the first reference feature data corresponds to a first location of the sliding window on the reference content, and the second reference feature data corresponds to a second location of the sliding window on the reference content. - View Dependent Claims (11, 12, 13)

14. A method for facilitating transfer authorization for a reference content comprising multiple frames, the method comprising, for each frame of the reference content, performing:
-
determining sub-regions for a current-frame of the reference content;
extracting feature data for the sub-regions;
storing the extracted feature data in a database; and
storing transfer authorization criteria in the database. - View Dependent Claims (15)

16. An article, comprising:
-
a machine-accessible media having associated directives for authorizing transfer of a candidate content against a data store storing extracted feature data for reference content, wherein the directives, when accessed, results in a machine performing;
extracting first feature data from the candidate content, the extracting including apportioning the candidate content into plural sub-regions and extracting feature data from the plural sub-regions, wherein each sub-region is at most ten percent of the candidate content;
sending extracted feature data to a sever configured to perform selecting reference feature data from the data store, comparing extracted feature data with the reference feature data, and determining an authorization for transfer of the candidate content based at least in part on the comparing. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

-
receiving feature data for the candidate content comprising extracted feature data for a portion of the candidate content and extracted feature data for a first portion of the reference content;
selecting first reference feature data from the data storage, first comparing the received feature data to the first reference feature data;
authorizing transfer of the candidate content based at least in part on the first comparing;
determining a non-match between the received feature data and the first reference feature data;
selecting second reference feature data from the data storage comprising extracted feature data for a second portion of the reference content;
second comparing the second reference content to the received feature data; and
performing a sliding window comparison to match the received feature data against the reference content;
wherein the first reference feature data corresponds to a first location of the sliding window on the reference content, and the second reference feature data corresponds to a second location of the sliding window on the reference content. - View Dependent Claims (26, 27, 28)
