The present invention provides a security and privacy enhanced method for geolocation. The system works by creating a space called the N-4Tk space on top of the Internet by locating N geographically dispersed servers in the Internet and computing as the coordinate for any computing device on the Internet, its distance to the N servers. The distance is computed as the 4Tk distance which is the time taken by a message of size k to travel between two points at a particular time of day. The system can also be used iteratively where each iteration uses a different set of Slaves in order to close in on the user with finer granularity. Interesting benefits of the system include the difficulty for an attacker to misrepresent the location, and also while the system can hone in on a locale for the user it does not violate the user's privacy.
