Paris Attacks Heat Up U.S. Debate over Smartphone Data Encryption

Last week's deadly and coordinated terrorist attacks in Paris have prompted some law enforcement officials to renew their calls for back doors to encrypted communications. But privacy and civil rights advocates say those arguments ignore technological realities and place blame where it doesn't belong.

Yesterday, three days after the Friday evening attacks that killed 129 people at several different locations in the French capital, John Brennan, director of the U.S. Central Intelligence Agency, said thwarting terrorism has become more difficult because of "a number of unauthorized disclosures and a lot of handwringing over the government's role in the effort to try to uncover these terrorists."
Former CIA director James Woolsey has made even stronger statements, accusing former NSA contractor/whistleblower Edward Snowden of having "blood on his hands" for exposing surveillance strategies used by the U.S. and other governments.
However, while investigations into the Paris attacks are still in their early stages, there does not appear to be any evidence so far indicating that back-door access to encrypted communications would have helped officials prevent the attacks. The New York Times yesterday published an article citing French officials who said the attacks were coordinated using encrypted communications, but later withdrew those claims, noting officials "offered no evidence."
Use of 'Home-Brew' Strong Encryption
Tech executives and experts said recent comments about the need for a back-door bypass to end-to-end encryption Relevant Products/Services are just the latest incarnation of a crypto wars debate that has gone on for decades. They also noted that there is no technological way to defeat encryption that works only for good guys.
"The Paris attacks are horrific and reprehensible but the response should not be to undermine the cybersecurity of millions of people," said Harley Geiger, advocacy director and senior counsel at the Washington, D.C.-based Center for Democracy and Technology. Outlawing encrypted communications wouldn't prevent terrorist organizations from using their own "home-brew strong encryption" -- and some groups do in fact use such self-developed tools today, he told us.
"The world is moving to a place where we have to recognize that good guys and bad guys use encryption just like good guys and bad guys use cars," Geiger said. He added there are other means available to law enforcement officials and counterterrorism operations to detect signs of planned attacks. With investigations into Friday's attacks still ongoing, targeting encryption would be a "hasty reaction," Geiger said.

LG’s first flexible OLED phone due before the year is out

LG plans to launch a flexible OLED smartphone before the end of the year, the company’s VP of mobile has confirmed, though it’s unclear to what extent the work-in-progress handset will actually flex. The OLED panel in question is the handiwork of LG Display according to VP of LG mobile Yoon Bu-hyun, the WSJ  reports, with the proposed device set to launch sometime in Q4. LG Display’s work on flexible OLEDs has been underway for some time, though the company’s efforts have perhaps been overshadowed somewhat by rival Samsung’s YOUM development. Last year, according to a Korea Times report, LG Display was preparing for

Syrian Electronic Army claims credit for CBS Twitter accounts hack

Yesterday, several of CBS ’s Twitter accounts were hacked, including its main account, and its accounts for 60 Minutes, 48 Hours, and CBS Denver. The hackers got into the account and tweeted a series of things relating to President Obama and the United States being in cahoots with Al-Qaeda . The tweets also had links that led users to malware-infested sites. While CBS was able to regain access to its accounts, it was unable to figure out who was behind the attacks, until now. The Syrian Electronic Army , the same group that hacked 3 of the BBC’s Twitter accounts, claimed

Can Technology Do a Better Job of Finding Bombs?

 With the horrifying images of the Boston Marathon bombing still much too fresh in our minds, and with citywide marathons coming up this weekend in London, Hamburg, and Salt Lake City , law enforcement officers and citizens everywhere are asking how to prevent the tragedy from being repeated. As Columbia University School of International and Public Affairs adjunct professor Abraham Wagner observed last year, on the 11th anniversary of 9/11, there’s “no magic bullet o
