The double-random phase encryption (DRPE) algorithm is a robust technique for image encryption, dueto its high speed and encoding a primary image to stationary white noise. Recently it was reported thatDRPE in the Fresnel domain can achieve a better avalanche effect than that in Fourier domain, whichmeans DRPE in the Fresnel domain is much safer, to some extent. Consequently, a method based on DRPEin the Fresnel domain would be a good choice. In this paper we present an image-authentication methodwhich uses only partial phase information from a double-random-phase-encrypted image in the Fresneldomain. In this method, only part of the phase information of an image encrypted with DRPE in the Fresneldomain needs to be kept, while other information like amplitude values can be eliminated. Then, withthe correct phase keys (we do not consider wavelength and distance as keys here) and a nonlinearcorrelation algorithm, the encrypted image can be authenticated. Experimental results demonstrate that theencrypted images can be successfully authenticated with this partial phase plus nonlinear correlationtechnique
