The groups that have previously complained to the FTC regarding the Google/DoubleClick deal have not weighed in with their opinions on how private data should be collected, reports The San Francisco Chronicle.

The Center for Digital Democracy, Electronic Privacy Information Center (EPIC) and U.S. Public Interest Research Group have amended their complaint to the FTC regarding the deal to be more constructive. Their issues with the collection by the combined company of private information still stand but they are now setting out guidelines on how that information should be collected.

The groups suggest the FTC allow Google/DoubleClick to collect data only after obtaining the user's permission. Even then, they feel it should be deleted at the user's request. They also suggest Google be barred from selling that data to a third-party and that Google-collected data be held separately from that collected by DoubleClick.

Google says it is already meeting or exceeding best practices when it comes to protecting user information. It also says EPIC has refused invitations to discuss matters privately.
