Detection of phishing attack using visual cryptography in ad hoc network

Mobile ad hoc networks (MANETs) provide a wide range of applications such as disaster relief, military application, wireless sensor network (WSN), education, entrainment, health, commercial and civilian environments. One of its important applications is in commercial and civilian environments that cover e-commerce, vehicular services and networks of visitors at airports. Nowadays, phishing attacks are increasing with burgeoning rate for e-commerce websites. This paper provides a novel anti-phishing approach based on visual cryptography. According to this approach a user generates two shares of an image using (2, 2) visual cryptography scheme. Client stores the first share of this image and second share is uploaded to the website at the time of user registration. After this, website asks for some other information like second share of the image, user name, and password. These credentials of a particular user can change once per login. During each login phase, a user verifies the legitimacy of a website by getting secret information with the help of stacking both shares. There are many existing approaches based on cryptographic technique but they all suffer from False Positive notification. However, proposed approach does not suffer from False Positive (FP) notification and outperforms all existing approaches.
