In today's society we shared everything about ourselves to the world through our favorite social network sites like Facebook, Twitter, Linkedin, etc. Marketing and advertisement firms strategically use these information to projects new business opportunities. In fact, Facebook was reported to served 1/3 of all online ads and it is continuing growing at a rapid pace. My question for this bookmark is what will happen to all of us if our accounts information were stolen? Even a major player in the social network world like the Sony Playstation network couldn't prevent this and was hacked for the second time in weeks.
