Researches at George Mason University have discovered a way of tracking and then tapping into Voice over Internet Protocol (VoIP) conversations on the internet. Consequently, the National Science Foundation has given the researches a $307,436 grant to help them translate this new research into a tool to help the police use it to tap calls with VoIP. The researchers have only shown it to work on Skype conversations.

There a number of services on the internet to “anonymize” Skype calls using a middle-man proxy server, as it gives the illusion that the proxy server is talking the person on the other end, and not really the caller.
