S2NOW: Secure Social Network Ontology Using WhatsApp

Abstract

Communicating and sharing the ideas and feelings between human beings form the basis of social network. With the advent of different social network tools and applications, the task of networking between people has reached to next level, crossing bridges and boundaries. However, is there a connection or linkage between the frequent and sometime just random exchange of text messages between people using social network-based tools and applications and also are these messages secure? Or are they vulnerable to threat and attacks? Literature survey shows that very little work has been done in this direction. With this intention, in the current research work, a real-time case study has been taken identifying the creation of the social network between a group of persons who frequently chat using the WhatsApp Messenger application based on their common hobbies, choices, and areas of interest and applying cryptographic techniques to ensure the security of data (chats). The proposed study uses the Caesar Cipher Cryptographic Technique and newly proposed Block Quadra Crypto Technique for encrypting the chats and showcases a comparison between the two techniques. The results are encouraging and exceed the expectation.
