Optical image watermarking based on orbital angular momentum holography
《Chinese Physics B》2024年第12期269-277,共9页Jialong Zhu Jiaying Ji Le Wang Shengmei Zhao 
Project supported by the National Natural Science Foundation of China(Grant No.62375140);the Natural Science Foundation of Suqian,Jiangsu Province,China(Grant No.S202108);the Open Research Fund of the National Laboratory of Solid State Microstructures(Grant No.M36055);the Postgraduate Research&Practice Innovation Program of Jiangsu Province,China(Grant No.KYCX21-0745)。
We propose an optical image watermarking scheme based on orbital angular momentum(OAM)holography.Multiple topological charges(TCs,l)of OAM,as multiple cryptographic sub-keys,are embedded into the host image along with...
