[edit] Anti acoustic fingerprinting (speculative)

The hackers of the world need to come up with robust anti acoustic fingerprinting technology. This should basically involve adding random noise without reducing listening quality. Theoretically, it should be easy to come up with. Any info on this topic will be appreciated as it becomes available in the future. --Amit 04:45, 13 October 2006 (UTC)

Acoustic fingerprints are generally designed to analyze audio in the same general way that humans perceive it; The worst anyone could probably pull off is to make fingerprints not match with the already existing and "clean" recordings - but the tampered copies would still be identified as one. I would say it's also economically infeasible to separately tamper each copy of a recording, with different seeds – unless it's produced in very low quantities. In short, I'm sceptical about the effectiveness of this, not to mention that I fail to see any practical economical use for such a technology. -- intgr 05:50, 13 October 2006 (UTC)

But there is a potential practical use — although not an economical one as I can tell. YouTube under Google is planning to implement (as some other sites already have) acoustic fingerprints[1] supplied by media companies to weed out or disallow material. Robust anti acoustic fingerprinting could allow not only for user freedom, but also safeguard YouTube's popularity.

Whether a tampered copy would still be matched by a fingerprint for the original or not depends upon the robustness of the algorithms used on both sides. --Amit 06:56, 13 October 2006 (UTC)

Good point, I never thought of fingerprints being used for these kind of things. As for the latter, I just intended to state the obvious that copies of a single tampered file will still match a single fingerprint, even if it's different from the original. :) -- intgr 11:04, 13 October 2006 (UTC)

[edit] Image and video fingerprints

There exist image and also video fingerprint technologies, and these deserve mention on Wikipedia. At least two options exist:

1. Have a separate article for each type of item.
2. 1. Move this article to Media fingerprint.
   2. Separate specifics of fingerprinting each type of item, while merging commonalities.

Opinions are needed! --Amit 07:10, 13 October 2006 (UTC)

This particular article seems pretty specific to acoustic fingerprinting – I think you would be better off starting an entirely new article for media fingerprints and linking to more specific articles from there. -- intgr 11:04, 13 October 2006 (UTC)
