Google CEO Eric Schmidt has long maintained that YouTube, the company's hugely popular video site, would never filter uploads to block copyrighted content from getting added. Instead, it would help copyright owners search for their content on the site through a "Claim Your Content" tool. Now, though, a lawyer for the company has seemingly contradicted Schmidt, according to PCWorld.com . In opening statements defending the company against a $1 billion lawsuit from Viacom, he promised that so-called "fingerprinting" technology would be available by September to block uploads automatically. It's a dangerous step for Google to take, if true. Once YouTube gets in the business of policing copyright, it could lose the protections Google has argued it enjoys under the Digital Millennium Copyright Act. Did Google's lawyer goof — or is Schmidt backing down?
