Adeona uses software that has been under development for the past year. It sends encrypted notes about the laptop’s whereabouts to servers on the Internet. The service doesn’t give you the address and phone number of the person who’s stolen your laptop. It does provide the IP (Internet Protocol) address that it last used as well as data on what nearby routers it used to connect to the Internet. The service ships with an open-source license, anyone can take the code and improve it or even sell it.”]
