"Wives and girlfriends who suspect their partners have been viewing pornography on their computer can now expose the truth - even if they tried to cover their tracks. The Porn Detection Stick plugs into a computer and scans the entire hard disk and internet history for lewd images. It detects skin tone and body parts in all types of files, using the same forensic software employed by police forces worldwide."
It doesn't tell us anything about shortcut links, cookies etc, so presumably it scans file contents only.
Sorry Jupiter
