Too Cute for Their Own Good, Robots Get Self-Defense Instincts

The Wall Street Journal (06/19/16) Georgia Wells 

Robot designers are developing robots that appear non-threatening, but can take action when humans attracted to their cuteness interfere with the performance of their functions, such as guarding or patrolling a location. When one such machine, the egg-shaped K5 from Knightscope, is cornered by curious crowds, it stops moving until they lose interest and walk away, or emits a shriek when they become too intrusive. The face of the K5 incorporates security-patrol operations such as surveillance cameras, thermal and ultrasonic sensors, and a navigation laser. The creation of robots such as the K5 is patterned on tests conducted to document the conditions of robot abuse in places such as Osaka, Japan, where a machine designed to help seniors buy groceries was frequently targeted and damaged by children, despite vocalized cries for help. In another case, a hitchhiking robot with a friendly face deployed along roads to test human dependence was found destroyed in Philadelphia last summer. Designers say they are attempting to create more approachable robots partly to counter the prevailing view of destructive machines presented by movies. "Because of all the doomsday scenarios people imagine with robots, their makers have to insert some cuteness," says Google's Golden Krishna.

DARPA Is Looking for the Perfect Encryption App, and It's Willing to Pay

Motherboard (04/22/16) Franceschi-Bicchierai, Lorenzo 

The Pentagon's blue-sky research program is looking for someone to create the ultimate hacker-proof messaging app. The "secure messaging and transaction platform" would use the standard encryption and security features of current messaging apps such as Signal, but also would use a decentralized Blockchain-like backbone structure that would be more resilient to surveillance and cyberattacks. The goal of the U.S. Defense Advanced Research Projects Agency (DARPA) is "a secure messaging system that can provide repudiation or deniability, perfect forward and backward secrecy, time to live/self delete for messages, one-time eyes-only messages, a decentralized infrastructure to be resilient to cyberattacks, and ease of use for individuals in less than ideal situations," according to a recent notice for proposals. DARPA wants "a public wall anyone can monitor or post messages on, but only correct people can decrypt," says Frederic Jacobs, an independent security researcher. He notes one problem with this approach is the structure would have higher latency and be harder to deploy at scale. DARPA's effort also suggests the rise of encryption apps is inevitable.
