Third Party tracking files

• “The first time a site is visited, it installs a tracking file, which assigns the computer a unique ID number. Later, when the user visits another site affiliated with the same tracking company, it can take note of where that user was before, and where he is now. This way, over time the company can build a robust profile.”

• Beacons• a.k.a. pixel tag, web bug• Invisible image embedded in

webpage• Image is not place there by

website, but by other company for ad tracking
