摘要
在双随机相位并行加密系统中, 多个图像之间的串扰噪声是获得高质量解密图像的主要挑战之一。为了解决传统双随机相位多图像并行加密系统的串扰噪声问题, 将快速响应码(QR码)作为数据容器, 提出了一种利用双随机相位并行加密系统进行多图像加密的无噪声图像恢复方案。仿真结果证明, 此方案可以有效地消除该系统多图像加密的串扰噪声问题。该方法具有获得无噪声解密图像, 抗噪声攻击鲁棒性好等优点。从实际的智能手机收集到的结果验证了方案的可行性。
Abstract
In double random phase parallel encryption system, the crosstalk noise among multiple images is one of the major challenge to get high-quality decrypted images. In order to solve the crosstalk noise problem of the traditional double random phase multi-image parallel encryption system, the fast response code (QR code) as a data container is used, and a noiseless image restoration scheme for multiple image encryption using a double random phase parallel encryption system is proposed. The simulation results show that this scheme can effectively eliminate the crosstalk noise problem of multi-image encryption of this system. Compared with the past methods, the proposed method has some advantages, such as obtaining noise-free decrypted images, better robustness against noise attacks, more relaxed working conditions and so on. The results gathered from the actual smartphone validates our scheme.
