Google's project to scan libraries full of books has been stalled by a copyright infringement lawsuit filed in 2005 by the Authors Guild and publishers. A New York court will hold a hearing on a plan to settle that lawsuit on October 7.
The settlement has been attacked from a variety of angles, one of them being concerns that the privacy of people accessing books through Google could be compromised.
Secondary uses of data refers to a practice like using a list of books read in order to decide which advertising to show a Google Books user.
In a separate statement, FTC Chairman Jon Leibowitz said his agency would press for consumer privacy to be protected.
"The Google Books initiative could provide a wealth of benefits for consumers, yet it also raises serious privacy challenges because of the vast amount of user information that could be collected," he wrote.
As part of a settlement of the copyright infringement lawsuit, Google has agreed to pay $125 million (£76 million) to create a Book Rights Registry, where authors and publishers could register works and receive compensation.
Under the settlement, authors have until the end of this week to opt out of the settlement.
The proposed settlement has been criticized by Google's rivals, Amazon.com, Microsoft and Yahoo, and by privacy advocates.
The American Library Association and Association of Research Libraries have asked for court oversight. They fear that if the service becomes a necessity for libraries, they would face monopoly pricing.
The U.S. Justice Department is investigating the deal for possible antitrust violations while European Union antitrust enforcers, prompted by Germany, have said they would study it.Reuse content
