The federal government is funding the development of a prototype surveillance tool by George Mason University researchers who have discovered a novel way to trace Internet phone conversations. Their project is designed to let police identify whether suspects under surveillance have been communicating through voice over Internet Protocol (VoIP)--information that would be unavailable today if people choose to communicate surreptitiously. The eavesdropping technique already has been shown to work with Skype, the researchers say.

Skype, nice program but who knows how 'secure' it is?
security through obscurity. security by keeping an exploitable weakness hidden
a cryptosystem should be secure even if everything about the system, except the key, is public knowledge
