A federal judge has ordered Google to turn over to Viacom its records of which users watched which videos on YouTube, the Web’s largest video site by far.
The order raised concerns among YouTube users and privacy advocates that the video viewing habits of tens of millions of people could be exposed. But Google and Viacom said they were hoping to come up with a way to protect the anonymity of the site’s visitors.
Viacom also said that the information would be safeguarded by a protective order restricting access to the data to outside lawyers, who will use it solely to press Viacom’s $1 billion copyright suit against Google.
Still, the judge’s order, which was made public late Wednesday, renewed concerns among privacy advocates that Internet companies like Google are collecting unprecedented amounts of private information that could be misused or fall unexpectedly into the hands of third parties.
“These very large databases of transactional information become honey pots for law enforcement or for litigants,” said Chris Hoofnagle, a senior fellow at the Berkeley Center for Law and Technology.
For every video on YouTube, the judge required Google to turn over to Viacom the login name of every user who had watched it, and the address of their computer, known as an I.P. or Internet protocol address.
Both companies have argued that I.P. addresses alone cannot be used to unmask the identities of individuals with certainty. But in many cases, technology experts and others have been able to link I.P. addresses to individuals using other records of their online activities.
The amount of data covered by the order is staggering, as it includes every video watched on YouTube since its founding in 2005. In April alone, 82 million people in the United States watched 4.1 billion clips there, according to comScore. Some experts say virtually every Internet user has visited YouTube. Read more
