Last year, Edward Snowden leaked National Security Agency documents that remind us the insecure of our privacy. Here is an interactive world map, taking reference from the Snowden reports on surveillance by NSA, shows which countries are being intercepted by the spy services from the Western World (Five Eyes group – the US, UK, Canada, Australia and New Zealand).
The map is created by Sniffmap, which has run random tests on international internet traffic originating from a country for checking how many routes are intercepted by Five Eyes.
The concept of this map is checking if an internet route between two IP addresses would pass by an NSA controlled country. If yes, the route will be considered as intercepted that you can see around 80% of the routes are captured by Five Eyes in the map.
Limitations of the map:
Sniffmap admits that the map fails to take account data captured by non-Five Eyes countries.
The map depends on geographic IP to determine location of routers, which is not 100% accurate.
This map is lacking most of the data from African countries that you could improve it by contributing traceroute results.
