The collection of such personal information poses far-reaching privacy concerns that the Commission should address, the three advocacy groups said.
"Neither Google nor DoubleClick have taken adequate steps to safeguard the personal data that is collected. Moreover, the proposed acquisition will create unique risks to privacy and will violate previously agreed standards for the conduct of online advertising," the groups wrote in the complaint, filed with the FTC.
Those standards include the Organization for Economic Cooperation and Development (OECD) Privacy Guidelines.
The three groups called on the FTC to investigate what effect a Google-DoubleClick merger will have on Google's ability to track and profile Internet users' activities.
They also want the FTC to order DoubleClick to remove cookies and other identifiers identifying individual users from any records it transfers to Google, unless the company has previously obtained explicit consent from those the data relates to, including giving users the right to first inspect, delete and modify the data.
Other demands include ordering Google to explain publicly how it plans to comply with privacy standards such as the OECD Privacy Guidelines, ordering the company to provide reasonable access to personally identifiable data it holds to the subject of that data, and establishing a meaningful data destruction policy.
