基于相移干涉术的光学信息隐藏系统的软件实现
Software realization of optical information hiding system based on phase-shifting interferometry
摘要
Abstract
Combining the techniques of double random phase encoding and phase-shifting interferometry, an information hiding system is proposed, in which the information to be hidden can be encrypted into multiple interferograms. By choosing the appropriate weighting factor, the interferograms can be embedded in the host image. The secrete information can be successfully extracted and decrypted by special phase-shifting reconstruction formula and inverse Fresnel diffraction transform. A software of information hiding system is designed by mixed programming between Visual C++ and Matlab based in the Matcom software environments. By testing the software interface, the designed software can successfully realize the main functions, such as image reading and displaying, input of basis geometrical parameters, information encrypting and embedding, information extracting, decrypting, robustness testing, etc..关键词
