Deriving multiple fingerprints from audio or video content
View Patent ↗Methods and apparatuses are provided for determining a first fingerprint of audio or video data. The first fingerprint is stored in a database or record including information pertaining to a first user or first account. The audio or video content is altered to yield a different version of the audio or video content, and a second fingerprint is determined from the different version of the audio or video content. The second fingerprint is stored in a database or recording including information pertaining to a second user or second account.
1. A method comprising:
determining a first fingerprint of audio or video content;
storing the first fingerprint in a database or record including information pertaining to a first user or first account;
altering, using an electronic processor, the audio or video content to yield a different version of the audio or video content, wherein altering the audio or video content comprises randomly or pseudo-randomly filtering the audio or video content, wherein the alterations that yield the different version of the audio or video content are imperceptible to a listener;
determining a second fingerprint of the different version of the audio or video content; and
storing the second fingerprint in the database or record including information pertaining to a second user or second account.
2. The method of claim 1 , wherein the electronic processor is a component of the Digital Rights Management (DRM) system that is compatible with at least one other DRM system.
3. The method of claim 1 , wherein the electronic processor is a component of a Digital Rights Management (DRM) system that is compatible with at least one other DRM system.
4. The method of claim 1 , wherein the second fingerprint provides a forensic identifier associated with the second user or second account.
5. The method of claim 1 , wherein the first fingerprint or the second fingerprint is associated with system default usage rights.
6. An apparatus comprising:
a memory configured to buffer audio or video content; and
one or more electronic processors configured to:
determine a first fingerprint from the buffered audio or video content;
store the first fingerprint in a database or record including information pertaining to a first user or first account;
alter the buffered audio or video content by randomly or pseudo-randomly filtering the audio or video content to yield a different version of the buffered audio or video content, wherein the alterations that yield the different version of the audio or video content are imperceptible to a listener;
determine a second fingerprint of the different version of the audio or video content; and
store the second fingerprint in the database or record including information pertaining to a second user or second account.
7. The apparatus of claim 6 , wherein the apparatus comprises an online music store.
8. The apparatus of claim 6 , wherein the audio or video content comprises pre-release content and wherein the different version of the audio or video content comprises content for commercial release.
9. The apparatus of claim 6 , wherein the one or more electronic processors are components of a Digital Rights Management (DRM) system that is compatible with at least one other DRM system.
10. The apparatus of claim 6 , wherein the second fingerprint provides a forensic identifier associated with the second user or second account.
11. The apparatus of claim 6 , wherein the first fingerprint or the second fingerprint is associated with system default usage rights.
12. A non-transitory computer-readable storage medium having instructions stored thereon, the instructions comprising:
instructions to determine a first fingerprint from audio or video content;
instructions to store the first fingerprint in a database or record including information pertaining to a first user or first account;
instructions to alter the audio or video content to yield a different version of the audio or video content, wherein the instructions to alter the audio or video content comprises instructions to randomly or pseudo-randomly filter the audio or video content, wherein the alterations that yield the different version of the audio or video content are imperceptible to a listener;
instructions to determine a second fingerprint from the different version of the audio or video content; and
instructions to store the second fingerprint in the database or record including information pertaining to a second user or second account.
13. The non-transitory computer-readable storage medium of claim 12 , wherein the audio or video content comprises pre-release content, and wherein the different version of the audio or video content comprises content for commercial release.
14. The non-transitory computer-readable storage medium of claim 12 , wherein the second fingerprint provides a forensic identifier associated with the second user or second account.
15. The non-transitory computer-readable storage medium of claim 12 , wherein the first fingerprint or the second fingerprint is associated with system default usage rights.
