Tor has been the network of choice for activists, journalists, military, and anyone else who would wishes to keep their internet activity private. However, Tor isn’t a perfect system. Past experiments have shown that by observing data traffic through a few well-placed nodes on the network, the identities of a number of users can be compromised.
Computer scientists at the Massachusetts Institute of Technology (MIT) have developed a new SMS text messaging system that is untraceable and apparently even more secure than the Tor anonymity network, in order to create truly anonymous communications.
In July, researchers from MIT and the Qatar Computing Research Institute (QCRI) succeeded in cracking a security vulnerability affecting the Tor anonymity network to make it possible to identify hidden servers with up to 88% accuracy.
