Social networking sites are well developing Internet applications that provide people to extend their real world social lives to a virtual social environment in the cyberspace. Social networking site is actually a double-edged sword, while providing enhanced social values, it also pose a risk of the dissemination of private information to outsiders. In Taiwan, leading social network websites, such as Wretch.cc, has several privacy disclosures which result in damage of personal reputation or in other inconvenience. Since Taiwan might be still immature in the privacy point of view, we would like to discuss the network privacy environment in Taiwan, and try to make some suggestions to improve privacy protection.
