JAP makes it possible to surf the Internet anonymously and unobservably. Without anonymization, every computer in the internet communicates using a traceable Address. That means the website visited, the Internet service provider (ISP), and any eavesdropper on the internet connection can determine which websites the user of a specific computer visits. Even the information which the user calls up can be intercepted and seen if encryption is not used. JAP uses a single static address which is shared by many JAP users. That way neither the visited website, nor an eavesdropper can determine which user visited which website.
