Clever Cryptography Could Protect Privacy in Covid-19 Contact-Tracing Apps
WiredBefore the Covid-19 pandemic, any system that used smartphones to track locations and contacts sounded like a dystopian surveillance nightmare. "For the infected person, there's protection because their information has been already redacted and hashed," says Ramesh Raskar, a professor in MIT's Media Lab leading the project. If the government agency or health care organization controlling the server wants to violate the privacy of the infected users, it's still possible to "crack" those hashes by hashing all the possible times and locations on a map. Their system would report redacted, hashed location trails of infected users to a health care authority through a so-called Mix Network: a collection of at least three servers controlled by different entities. Like the onion routing system used by the anonymity software Tor, each of those intermediary servers would mix up the hashed, timestamped locations of users before passing them on to the next one, so that by the time they reach the government authority storing the hashes, that final server wouldn't be able to associate any of those hashed locations with a specific user.
