Information security is a prime concern especially when it comes to business and corporate sectors where off the record information should be given utmost importance. Very cooperative especially to business enterprise, modern day expertise has contributed a lot towards sharing a surreptitious data. The field of wireless communication has surmounted many hurdles in the past few years and is now finally capable of supporting higher data rates thanks to the development of Orthogonal Frequency Division Multiplexing (OFDM). It is the most ideal format for broadband communication to meet its need for higher data rates. This study further augment the usefulness of OFDM communication by making it secure to avert data piracy. This study propose an idea of embedding the secret message at the real part of Inverse Fast Fourier Transfonn (IFFT) output of OFDM system and performance of the system is examined for various modulations. Thus, this study is a conjunction of wireless and data security which serves the purpose of secret sharing and can be applicable and suitable to entrepreneurial activities.
