The objective behind the proposal studies around oversampling of Fourier coefficients and their applications. I intend to study how oversampling of Fourier coefficients can be used for hiding messages. In the following report oversampling of Fourier coefficients has been discussed as providing room for storing or transmitting hidden information. The scheme aims at transmitting an arbitrary signal and, simultaneously, embedding a hidden code. The most important feature of this scheme is that without the knowledge of exact oversampling parameter the hidden code cannot be retrieved. This parameter provide the key for retrieving the code.
