A New Approach to SMS Steganography using Mathematical Equations
This addresses security concerns for mobile phone users by enhancing SMS steganography, though it appears incremental as it builds on existing steganography techniques.
The paper tackles the problem of securing SMS messages against cyber-crime by proposing a new SMS steganography approach using mathematical equations to hide secret messages, achieving up to 35 characters (25%) hidden in a single 140-character SMS.
In the era of Information Technology, cyber-crime has always been a worrying issue for online users. Phishing, social engineering, and third party attacks have made people reluctant to share their personal information, even with trusted entities. Messages that are sent via Short Message Service (SMS) are easily copied and hacked by using special software. To enforce the security of sending messages through mobile phones, one solution is SMS steganography. SMS Steganography is a technique that hides a secret message in the SMS. We propose a new approach for SMS steganography that uses a mathematical equation as the stego media in order to transmit the data. With this approach, we can hide up to 35 characters (25%) of a secret message on a single SMS with maximum of 140 characters.
