Too Much Text About CS Table

This week we'll be talking about Youtube and its efforts to enforce the rights of copyright holders with its ContentID system. Early this month, a federal appeals court in San Francisco "affirmed that copyright holders must consider whether a use of material is fair before sending a takedown notice".

This ruling is the latest development in an on-going battle between copyright holders, Youtube content creators who use the copyright holders content, and Youtube's system---ContentID---to help automatically enforce copyright in its system.

To understand the situation, please read this Gamasutra article---a primer on ContentID for Youtube content creators:

Then catch up on the background of this latest court ruling:

If you are interested in how Google actually checks for copyright infringement of millions of videos, this algorithmic technique is called fingerprinting. Here is a short technical paper from Google on the approach that ContentID takes (based on finite-state transducers versus traditional hashing methods):
