The National Security Agency has been inserting files known as cookies onto the computers of individuals who visit the NSA Web site, a violation of federal rules meant to protect privacy.
The cookies, which can be used to track visitors’ online activities, vanished this week following complaints from a privacy activist and inquiries from The Associated Press. On Wednesday, NSA officials admitted using the cookies, but said that the agency had made a mistake.
Mistake, or Tracking? You decide.
