The system of loading hidden information in random spectrum of Fourier domain and incremental compensation, which is based on optical principle and can be used in optical image information hiding, is proposed in this paper. A typical method of loading hidden information to the system is also presented. The random spectrum of host image multiplied by random phase mask is obtained by Fourier transform, and the hidden information is embedded in the random spectrum. At the same time, the effects induced by the hidden information can be compensated for by the proposed system. When the carrier image embedded with hidden information is decrypted with incorrect key-random phase mask, the hidden information will spread in the Fourier frequency domain, thus it is impossible to retrieve the hidden information. In addition, even though the attackers know the presence of hidden information and even the hiding method, they still can not decrypt the hidden content without the key, and it is also difficult to removal the hidden information without destroying the carrier image. While in the decryption process, neither the original image nor the information related to the hidden code is necessary. The feasibility of proposed system is demonstrated by simulation experiment and the robustness to the Gauss noise as well as salt and pepper noise is also presented at the end of this paper.
