In Wikipedia (http://en.wikipedia.org/wiki/Sexting), the term "Sexting" is defined as "Sexting (a portmanteau of sex and texting) is the act of sending sexually explicit messages or photos electronically, primarily between mobile phones."
From the technical standpoint, it requires to have (a) digital camera and (b) device for sending messages (emails) with pictures, such as cell phone or computer. Modern cell phones, such as iPhones, SmartPhones or BlackBerries has all these capabilities – camera and Internet connection.
The social danger of sexting is that these messages or photos can be widely distributed over the Internet beyond the originator's control.
Sexting could have very serious legal consequences if it involves someone under the age of 18, because it constitutes child pornography, according to Parry Aftab, an Internet privacy and security lawyer. "If you take a picture, you can be accused of producing child pornography; if you send it to somebody, you can be accused of distributing child pornography; and if you keep a picture, you can be accused of possessing child pornography," Finally: "Anywhere along this chain of transmission of the images, you can be charged as a registered sex offender."
FBI's Parent's Guide to Internet Safety (http://www.fbi.gov/publications/pguide/pguidee.htm) suggests:
"Review what is on your child's computer. If you don't know how, ask a friend, coworker, relative, or other knowledgeable person. Pornography or any kind of sexual communication can be a warning sign."
"Monitor your child's access to all types of live electronic communications (i.e., chat rooms, instant messages, Internet Relay Chat, etc.), and monitor your child's e-mail."
But this could be a difficult task to do, especially consider the very sensitive matter of monitoring. If you need private monitoring of emails, webmails, instant messenger's chats, websites visited, you can easy use BlackBox Security Monitor. It is very effective and it is free.
