Yep Smart Devices Do Spy On You – 2 Computer Scientists Explain How The Internet Of Things Can Violate Your Privacy

Have you ever felt a creeping sensation that someone’s watching you? Then you turn around and you don’t see anything out of the ordinary. Depending on where you were, though, you might not have been completely imagining it. There are billions of things sensing you every day. They are everywhere, hidden in plain sight – inside your TV, fridge, car and office. These things know more about you than you might imagine, and many of them communicate that information over the internet. Back in 2007, it would have been hard to imagine the revolution of useful apps and services that smartphones ushered in. But they came with a cost in terms of intrusiveness and loss of privacy. As computer scientists who study data management and privacy, we find that with internet connectivity extended to devices ...

A Creative Route To Making Robots And Other Mechanical Devices – Curved Origami

Building robotic grippers that can firmly grasp heavy objects and also gently grasp delicate ones usually requires complicated sets of gears, hinges and motors. But it turns out that it’s also possible to make grippers out of simple sheets of flexible material with the right creases in them. Our lab at Arizona State University has designed curved fold patterns that can change stiffness and flexibility. Flexible materials shaped with these patterns can be used to make simple, inexpensive robotic grippers, swimming robots and other mechanical devices. People naturally vary the amount of stiffness needed to handle fragile and sturdy objects appropriately. Robots interact with the environment in the same way. Curved folding is a simple way to give robots the ability to vary the amount of sti...

Workplaces are turning to devices to monitor social distancing, but does the tech respect privacy?

As we emerge from the coronavirus lockdown, those of us who still have a workplace may not recognize it. Businesses, eager to limit liability for employees and customers, are considering a variety of emerging technologies for limiting pandemic spread. These technologies can be loosely divided into two types: one based on cellphone technologies and the other using wearable devices like electronic bracelets and watches. Both approaches focus on maintaining social distancing, nominally six feet between any two workers based on the U.S. Centers for Disease Control and Prevention guidelines and supported by some modeling. Most workers will have little choice whether to participate in their employer’s risk mitigation. As a networking and security researcher, I believe that it is essential that...
