SMS is one of the mostly used services in mobile phones throughout the world. Using this service, individuals can write and send short messages to each other. Information security is a critical issue in this digitalized world. Stegnography is a new concept for transformation of secure data. In mobile phones, two default types of fonts are used. They are System and Proportional fonts, which have related figures to human visualization and cannot recognized by human eye. The proposed method hides the secret data(0,1) in cover SMS message by changing the fonts of each character by one of those two fonts (1 represented by Proportional fonts and 0 represented by System fonts). After embedding secret information in cover message, the Stego message will look like an common message but each character draw in one of these fonts. In extraction side, it must analyze each character font to retrieve secret information.Most of these techniques are executed on J2ME (Java2 Micro Edition) platform.
