In the internet base new media, with all types of social networking sites, personal information is really easy to be spread without our notice. Therefore, privacy and confidentiality must be taken into account prior to post anything online. I think with regard to these two issues of privacy & confidentiality, it is really out of our control in today’s internet base social networking. If you don’t post any personal information on the social networking sites, nobody is going to add you as friend, it violated the principle of socialize. Online social networking has become the fashion and will become the tradition of social life. In order to adjust yourself into this fashion, you must give out some of your privacy rights. Losses and gains are always two inseparate components. However, lost of privacy is really a serious problem. The identity thefts can use your information to do something harmful. I would like to share a little story of mine. Just 3 days ago, I received a mail with a $100 rebate card under my name from AT&T. But I never has any business with AT&T. I soon realized it must be someone who had used my information. And if there is a rebate card, then there must be a bill follows. So, I definitely can’t redeem this rebate card. And I called AT&T with regarding to this issue and cancelled the rebate card. AT&T also promised me, they will handle my case with no future obligation. This lesson taught us that internet and social networking sites are very unsafe, but I am still using them. Just can’t get away and live without it. That’s really IRONY.
