image can be transmitted to and captured by a CCD
at the receiving end, and then decrypted via simple
logical operations. The autocorrelation between the
original and the decrypted images shows 100%
similarity. The decrypted 3D image can be displayed
via the holographic display technology. Having the
integrity that is comparable to that of traditional
optical holographic encryption, this technique has
the convenience and simplicity of digital
holographic processing and thus provides a secured
solution for holographic information transmission.
