Abstract – Due to the rapid growth of optical encryption and compression techniques, authentication of encoded information has the most significant process for providing high levels of optical security. The present optical encryption and compression methods can provide the secure access to the information and such techniques are improving day by day. In previous researches, hybrid optical encryption and compression was proposed with multiplexing scheme for encrypting and compressing the multiple images simultaneously. However, the classification of the encoded images using SVM and K-NN was simple and easily to distinguish for identifying the images which are obtained from fake samples and genuine samples. Hence in this paper, an Extreme Learning Machine (ELM) based classification is proposed for classifying the images which are encoded using the different approaches in order to evaluate the encoded performance. The main aim of this paper is to develop an optical system which has the highest-level of optical security with high identification complexity for identifying the encoded images. Finally, the experimental results show that improved security level by reducing the classification accuracy of encoded image identification.
