In Pictures: 7 hidden dangers of wearable computers

Wearable computers like smart clothes and smart watches offer a myriad of benefits, but also raise security concerns. Here are 7 worries associated with wearable devices.

Wearable/embedded medical devices Many wearable medical devices such as insulin pumps, glucose monitors and pacemakers these days are wireless-enabled, making them vulnerable to hacking attacks. More than two years ago, a researcher at the Black Hat security conference showed how an attacker could take control of an insulin pump from a half-mile away to deliver a potentially lethal dose to the user. Another researcher has demonstrated how the wireless protocols in modern pacemakers could be exploited to deliver a fatal 830-volt shock to someone wearing the device.

Concerns over such threats prompted doctors for former vice president Dick Cheney to disable the wireless capability of his heart pump. The U.S. FDA has also expressed concern over the issue and urged device makers to address wireless vulnerabilities.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
