Christopher Soghoian: A brief history of phone wiretapping -- and how to avoid it

August 20, 2015 - 14:48
Who is listening in on your phone calls? On a landline, it could be anyone, says privacy activist Christopher Soghoian, because surveillance backdoors are built into the phone system by default, to allow governments to listen in. But then again, so could a foreign intelligence service ... or a criminal. Which is why, says Soghoian, some tech companies are resisting governments' call to build the same backdoors into mobile phones and new messaging systems. From this TED Fellow, learn how some tech companies are working to keep your calls and messages private.

Matt Kenyon: How I snuck a memorial for Iraqi civilians into the US government

August 13, 2015 - 15:07
It’s estimated that 150,000 to 1 million Iraqi civilians died as a result of the US-led invasion in 2003. Artist Matt Kenyon wanted to create a monument for them. But rather than build a large stone pillar, he made his monument small in size and easily replicable. He’s spent five years sneaking it into the halls of power -- including directly into the hands of a US Attorney General who held office during the war, in an exchange caught on tape.

Benedetta Berti: The surprising way groups like ISIS stay in power

August 10, 2015 - 14:57
ISIS, Hezbollah, Hamas. These three very different groups are known for violence — but that’s only a portion of what they do, says policy analyst Benedetti Berti. They also attempt to win over populations with social work: setting up schools and hospitals, offering safety and security, and filling the gaps left by weak governments. Understanding the broader work of these groups suggests new strategies for ending the violence.
