Abstract

In this paper we present a highdimension image encrypting method to encrypt 3D color image Inspired by the fact that light field camera can capture both the spatial information and directional information we use a microlens array to obtain both the 2D spatial and 2D directional information to form the 4D distributions of light beams then the chaotic method and Arnold transform are employed to encrypt the spatial information and directional formation respectively The decrypted 4D light field data can be used to reconstruct image with adjustable focal length Numerical simulations show that the proposed method has high sensitiveness to its key spaces and high security in statistical information In addition test results illustrate that the proposed method has strong robustness when occlusion attacks occurThis work is supported by the Natural Science Foundation of Zhejiang Province of China Grant No LQ16F050003 the Research Found of Zhejiang Province Department of Education Grant No Y201430970 the National Natural Science Foundation of China Grant No 61205015 and the Research Fund for the Doctoral Program of Higher Education of China Grant No 20123120130001
