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.
Researchers at the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed a prototype privacy network to rival Tor, an anonymizing network that uses special routing to protect privacy, and named it after one of the most annoying musical instruments in the world.
Vuvuzela is a private communication network in a similar category to Tor, I2P and HORNET, but instead of just encrypting and hiding the delivery of messages, it includes a blaring atmosphere of noisy spam to help hide legitimate conversation.
