Implementation of a hybrid opto-digital multiple information hiding and real-time extraction system
2002
In this paper, a new hybrid Opto-Digital multiple information hiding and real-time extracting system is suggested and implemented. The multiple information hiding system in which the multiple information can be hided in an arbitrary cover image is digitally implemented by using the random sequence and Hadamard matrix. In addition, a real-time optical extraction system in which the hidden information in a cover image can be extracted in real-time is implemented by using an optical NJTC. From good experimental results on the digital hiding and optical extraction of some English alphabet characters, it has been suggested, in this paper, that implementation of hybrid Opto-Digital multiple information hiding and real-time extraction system can be possible.© (2002) COPYRIGHT SPIE--The International Society for Optical Engineering.
