We propose a modified encryption joint transform correlator scheme that introduces an additional randomphase mask. The positions of both the conventional and the new mask are crucial for successful recovery ofthe original data. Although the two random phase masks are 2D, variation of their relative distance constitutesan additional dimension. Consequently by including this notion, both random phase masks act as a 3-dimensional (3D) key code increasing thereby the security with respect to the conventional JTC encryptionscheme. We employ this scheme to multiplex encrypted data, displacing the encoding masks. Duringdecryption of the multiplexed information, we only reconstruct the object that matches the correctpredetermined 3D key code, i.e. that matches the random masks positions in the encryption step. We presentactual experimental results, by using BSO crystal as recording medium, as well as their respective analysis.fied encryption joint transform correlator scheme that introduces an additional randomphase mask.
