NEW YORK (CNN/Money) - A consumer advocacy group filed a complaint against Amazon.com Tuesday, alleging the online retailer set up a "veil of ignorance" in the methods it uses to collect personal information from children.

The Electronic Privacy Information Center (EPIC), a Washington, D.C.-based non-profit research group, filed the complaint with the Federal Trade Commission, claiming Amazon.com does not comply with a congressional act requiring firms to take steps to protect the confidentiality and security of the information collected from children.

EPIC alleges the company markets its children's sections to kids under the age of 13, when the company says it does not.

"Amazon has constructed such a 'veil of ignorance,'" the complaint says. "It operates a site featuring products tantalizing to children, and then disclaims any responsibility for marketing to children by asserting in its privacy policy that it technically only sells products to adults."

The complaint also says the group found several individuals under 13 who are registered users of Amazon.com and have submitted their names, addresses and e-mail addresses.

Amazon.com spokesman Bill Curry maintained that the site is not directed toward children. "It's a store that sells toys for adults to buy and you need a credit card to do that. The [congressional act] applies to sites that are directed toward children."

He added that the company would work with the FTC to resolve the complaint.

EPIC requested that the FTC order Amazon.com (AMZN: up $0.31 to $25.56, Research, Estimates) to delete the personal information of children posted on the site and investigate how Amazon.com collects and shares customer information.
