Paper Abstract

We have proposed an improved optic-electronic hybrid encoding technique for certificate validation based on works of Junji Ohtsubo and Ayano Fujimoto. Corresponding experiment was carried out for substantiating our proposed method. Our approach enhances the level of security by importing another key image, largely increasing the cipher space and inducing a better resistance to brutal attacks. Optical experiment exhibits while the encrypted results offered is a correct one and another licit one but contaminated by an Additive Gaussian Noise with a Standard Deviation of 0.4, the PSNR of decrypted image is 6.87 and 6.54, respectively. Experimental results indicate the effectiveness and robustness of this method. This paper conducts a beneficial exploration in the practical application of optical authentication technique.
