What is Browser history sniffing definition ?

Browser history sniffing is an illegal and malicious way to know if a visitor has previously visited some pages or web sites without using cookies and to infer some precious centers of interest for targeting purposes.

Browser history sniffing is based upon the browser default feature that changes links color when a user has visited them.

A malicious company creates invisible pages consisting of thousands of links to websites containing information on sensitive or high value topics. If a person happened to visit a site in the list, the company could see which links had been visited previously and store that information in a cookie for future targeted advertising.
