An encrypted hiding scheme for 3D objects based on CGH and Henon mapping

Xiangxiang Ji,

et al.

Abstract: A method is proposed to enhance the security of three-dimensional (3D) objects through computer-generated hologram (CGH) encryption and hiding. The process begins by encoding the 3D object using an iterative angular-spectrum layer-oriented method to create an optimized phase-only CGH. Next, the encrypted image is produced by modulating the phase-only CGH with a chaotic random phase mask (CRPM) generated through Henon mapping. Subsequently, a combination of discrete wavelet transform (DWT) and singular value de… Show more

“…The encryption characteristics and unique non-tearability of holographic technology [4][5][6] can meet the requirements of digital watermarking algorithms for robustness and anti-interference. Therefore, the combination of holographic technology and digital watermarking algorithms has significant research importance for realizing the full encryption of watermark information [7][8][9][10][11]. In 2002, Takai and Mifune [12] proposed a method using Fourier transform (FT) hologram as a watermark embedded in the host image, which is convenient for watermark extraction but has poor noise resistance and does not achieve blind watermark extraction.…”
