Ghost imaging is a novel imaging technique which the nature of it is based on calculating the second-order correlation function of two correlated or entangled beams. This feature of using two beams has been caused ghost imaging significance in optical encryption. In this paper, with the introducing of the selective method as a novel technique for ghost imaging and optical encryption based on this method experimentally, a comparison between previous encryption methods has been accomplished. Calculated value of the error rate parameter in unauthorized decryption shows the superiority and high security of selective method in optical encryption over previous methods.
Keywords: Correlation function, ghost imaging, optical encryption, selective method
