Abstract
In this paper, an encryption system is proposed based on polarization optics. A modulated image at reference plane was obtained by using a virtual magneto-optical modulator, and the field from the reference plane interfered with that from the information plane having the original image to form an encrypted image. This system not only has the advantages of multiple freedom degrees, high security strength and data manipulation in high-dimension as the traditional optical information processing system but also possesses the advantages of data processing flexibility in the computer information process. Numerical experiments prove that images encrypted by using this system have a high level of security, so it is hard for attackers to analyze the original images.
