Do you really know what your child is up to on the computer or smartphone? Technology, especially if you're a little behind the times, is deceptive; some of the worst apps and games appear as innocent ways to keep in touch with friends, but can turn into venues for inappropriate behavior.

According to a 2011 survey conducted by the Pew Research Center's Internet & American Life Project, 95 percent of teens between 12 and 17 use the internet, 27 percent of this group uploads video, and a whopping 80 percent use social media sites like Facebook on phones and the computer.
