Authentication system based on computer generated hologram

Recently, biometrics authentication has been used as various security systems. The problem is that the reliability of previous authentication decreases due to some code-breaking methods. Based on the background, the demand for new security is growing. This paper proposes new security system which uses binary hologram. It aims to add counterfeit prevention and a lot of information into previous binary hologram method. In addition, proposed method uses a high accuracy image registration called as Phase-Only Correlation method for improve the performance of security system. As a result, we achieved accurate reconstructed-image in the two dimensional image.
