EW – The Porn Detection Stick is a thumb drive device that will search through all the images on your computer. Scan them for pornographic content, and create a report of suspected pornographic images. It even scans deleted images and Internet cache files so there’s no hiding Internet activity. This means even if Internet Explorer cache files are deleted, many images can still be recovered and scanned for pornography. Best of all, no software is installed on the target machine so they don’t know you’ve performed a search. You can even securely delete objectionable images
