A new coherent superposition based single-channel color image encryption using gamma distribution and biometric phase keys, is proposed. In this method, first the original color image is split into R, G, and B channels and corresponding iris print image is also split into R, G, and B channels. Second, each channel of iris print image is phase encoded to use as biometric phase key. Third, the biometric phase key of each channel is independently multiplied with gamma distribution phase mask. Finally the original color channel can be directly separated into two phase masks: one is a combination of gamma distribution and biometric phase keys and the other is a modulation of the combination by the original color channel. The remarkable benefit of the proposed scheme is introduction of gamma distribution and biometric phase keys. The proposed system can be implemented by using a simple hybrid optoelectronic system. Numerical simulation results validate the feasibility and effectiveness of the proposed method.
A new color image cryptosystem is proposed, which is based on discrete cosine transform and spiral phase encoding in
gyrator transform domain. The random phase mask is replaced by a multiple-key spiral phase mask, because it is difficult
to replicate and easy to align. In this scheme, a color image is decomposed into red, blue and green color channels. Each
channel is encoded independently by using discrete cosine transform and then encrypted into a spiral phase mask. The
resulting image is gyrator transformed. The operations are performed twice continuously to get multiplexed encrypted
image at output plane. The rotation angles of gyrator transform along with the order, the wavelength, the focal length
and the radius of a spiral phase mask of each channel provide multiple choice for the parameter of the proposed security
system as encryption keys. The proposed optical setup avoids alignment problems. The performance, feasibility and
effectiveness of the proposed algorithm are demonstrated by the numerical simulation results.
