Detecting Malicious Activity in Facebook Application

The aim of this system is mainly to provide users a filtering mechanism to avoid their walls overwhelmed by useless data. Due to the fact that in FACEBOOKs there is the possibility of posting or commenting other posts on particular public/private areas. Information filtering can therefore be used to give users the ability to automatically control the messages written on their own walls, by filtering out unwanted messages. We have implemented an automated system, called ConnectifyMe, able to filter unwanted messages, images from FACEBOOK user wall. The images posted on the FACEBOOK wall which may contain vital information hidden in it, which leads to terrorist activities. For Filtering the images we provide a steganography mechanism that decodes the hidden data, making it more secure. There are possibilities of getting phishing links on the FACEBOOK walls, thus to alert the user about the phishing link, system is using an antiphishing algorithm called obURL, which has six different steps to filter the link and alert the user if phishing site is detected.
