Yesterday at an MIT Media Lab event called Forbidden Research, exiled NSA whistleblower Edward Snowden and American hacker Andrew "bunnie" Huang announced a new technology to counter lawful abuses of digital surveillance.

The tech, which at the moment is a prototype iPhone 6 case, uses the phone's antenna system to alert the user if any unusual radio signals are being received or sent.

Speaking to the audience live from a remote location, Snowden, who is now the director of the Freedom of the Press Foundation, defined a "lawful abuse" as "...an immoral or improper activity perpetuated or justified under a shelter of law."

Some examples include large-scale secret attempts at mass surveillance, torture, indefinite detention, extrajudicial killing (i.e. assassination), segregation, slavery, genocide. The list goes on.

To wrap the digital surveillance variable into the lawful abuse equation, one has to consider the cell phone, which by the very nature of how it works, makes it vulnerable to being spied upon.

Cellphones transmit radio signals that contain a unique identifier, which helps validate you to the phone company. But it can also be observed and monitored by dangerous third parties.

Dangerous, as in, people who might want to kill you.

Since 2005, more than 1,070 people working the media have been killed or gone missing. Snowden pointed out that the overwhelming majority of these deaths were murders and that the journalists themselves were mostly covering politics or political unrest.

Snowden told the story of Marie Colvin, who was reporting live from Homs, Syria, in 2012 for the British newspaper The Sunday Times when the building she was reporting from was bombed repeatedly. She and a French filmmaker were killed.

Later, it was discovered that the radio frequency signals from her phone were intercepted by the Syrian army and used to pinpoint her exact location.

Snowden and Huang want to develop technology that prevents a person's phone from being used as a tracking device, even if it's in airplane mode, even if the Bluetooth, Wi-Fi, GPS, and NFC (for Apple Pay) are supposedly turned off.
