Data hiding on social media communications using text steganography

Abstract

This research work proposes a steganography on social media communications. Nowadays, people frequently use messenger or social network such as Skype, Line, Facebook, Whatsapp and Twitter, etc. to communicate with other people and these platforms become popular to be used to exchange secrets or preserve personal information. Personal information like accounts and passwords might not be seen and embedded to cover objects when two clients communicate to each other. Those objects shall be pictures, music, or text messages. The proposed scheme will be deployed on the cover text. A strategy is designed to increase the capacity of hidden data and try to make any simple piece of text to be the cover text; such as letters, article of news or the common messages. The new approach – Extended Line will be adopted, and then together with White Space between to increase the capacity of a text. The simulation results disclose that the algorithm not only increases the capacity, but also increases the efficiency of decoding. Moreover, it still works on any kind of cover text.
