Microsoft's Don Dodge ponders the problems of filtering copyrighted content out of YouTube:
I was VP of product development at Napster when the RIAA and Federal judge asked us to filter out all copyrighted music. It was difficult with music...it will be nearly impossible for video.
The problem is completeness. You can put together hashing algorithms and "finger printing" techniques to find the obvious stuff...maybe 80% of the copyrighted content. The remaining 20% is nearly impossible to identify with precision and completeness.
The judge in the Napster case demanded 100% compliance, not 90% or 95%...100%. There was no way to effectively do it so the judge just shut Napster down.
The truth is that Viacom probably couldn't provide a 100% accurate list of their clips either. And, as time goes on it will get worse. Users will get very clever in disguising the clips they upload with different names, tags, sample rates, lengths, fake lead ins, etc.
This could get ugly...and expensive. My view is sunnier than Don's. Napster and the record industry were in a completely adversarial position, so the RIAA had no reason to moderate its demand for perfection. Google and YouTube are conducting a business negotiation, with the take-down demand as one element, and have no barrier to agreeing that less than perfection is acceptable.
