Robust image steganography with pixel factor mapping (PFM) technique

Our routine life is carrying an essential dependability on Internet Technologies and their expertise's in various activities. It has advantages and disadvantages. Technology requires information hiding expertise for maintaining the secrecy of the information. Steganography is one of the fashionable information hiding technique. Extensive competence of attempt has been agreed in this land by different researchers. In this contribution, a frequency domain image Steganography method using DCT coefficient has been proposed which has been design based on prime factor mapping technique.
