摘要：
In this paper, a light field image (LFI) encryption scheme based on pixel substitution and double random phase encoding (DRPE) is presented. The LFI includes the direction and intensity information of the light in the propagation process. Firstly, we employ an angular domain plane to represent the multi-view image of the LFI. Furthermore, pixel substitution processing based on rows and columns for a single view LFI. Finally, by the Fourier transform based on DRPE to obtain a encrypted image. Experimental results show that proposed scheme can be reliable and has a better immunity to noise and higher execution efficiency.
