... Collaborating research and network marketing through social networking website. Although young generation is fond of these applications, social networking websites also encounter a number of privacy threats. These threats reveal the information security risks of social networking websites such as internet fraud, identity theft, virus and phishing. We propose a real-time website security protection mechanism based on the concept of proxy. The client side transmits information to the social networking website through proxy. The main function of the proxy is to detect and determine the security threats of the website. These threats include web-based malware, phishing websites and malicious connection. The idea is to integrate many commercial protection software and online security scanning services into a security module, simultaneously execute webpage security threat scan, then scan the information sent by the web server with the security module before sending to the client. If security threats were found in the web page, the system will add this web page to the blacklist and issue a warning to the client side to prevent attack. The functionality of proxy is to segregate the client and the networking threat. Using simultaneous scan of many protection software and online services can increase the recognition rate of security threats. Later one, as long as the client is to receive the webpage in the blacklist, a warning will be issued directly to the client side. Through this mechanism, we can lower the security risk of the clients using social networking websites. Popular interactive application services such as games, psychological tests and fan communities can also be used to conduct Trojan, virus and web linked code attacks, or even money transfer scams. For this reason, the security threats of social networking websites, such as Face book, Orkut, twitter and MySpace needs to be investigated and ameliorated. .
