Optics has provided a promising means for the development of information hiding in recent years. However, conventional optical information hiding systems can only hide a limited number of images, and optical implementation complexity is usually high in conventional methods. In this paper, we propose a new scheme to implement optical information hiding based on single-input multiple-output (SIMO) and binary amplitude-only holograms (AOHs) using the modified Gerchberg-Saxton algorithm (MGSA). Different from conventional optical hiding methods with the limited multiplexing capacity, the proposed scheme can retrieve a large number of different secret images from one single host image during optical retrieval. In addition, it is also illustrated that optical implementation complexity is reduced in the proposed method. Simulations and optical experiments are conducted to verify feasibility, security and robustness of the proposed method. It is expected that the proposed method could open up a different research perspective for optical multiple-image hiding.

通过改进的 Gerchberg-Saxton 算法基于单输入多输出和二进制仅幅度全息图的光学隐藏

近年来,光学为信息隐藏的发展提供了一种很有前景的手段。然而,传统的光学信息隐藏系统只能隐藏有限数量的图像,并且传统方法的光学实现复杂度通常很高。在本文中,我们提出了一种使用改进的 Gerchberg-Saxton 算法 (MGSA) 基于单输入多输出 (SIMO) 和二进制仅振幅全息图 (AOH) 实现光学信息隐藏的新方案。与具有有限复用能力的传统光学隐藏方法不同,所提出的方案可以在光学检索期间从单个宿主图像中检索出大量不同的秘密图像。此外,还说明所提出的方法降低了光学实现的复杂度。进行仿真和光学实验以验证所提出方法的可行性、安全性和鲁棒性。预计所提出的方法可以为光学多图像隐藏开辟不同的研究视角。
