When it comes to data security breaches, the bulk of the attention goes to problems with information storage and transmission. In fact, I recently wrote something about some particularly egregious, recent examples.

 But it turns out there's also a big threat posed by what's known as visual privacy issues-that is, data displayed on screens. With the rise of a mobile workforce, constantly working on laptops, tablets, and smart phones, sending and receiving emails and tapping proprietary corporate information while on the go, security breaches caused by visual information are also increasing.
