Abstract

We present several encryption techniques for holographic data storage, using orthogonal phase-code multiplexing and random phase encoding. Our system is capable of storing page-oriented data based on the selectivity of orthogonal phase-codes in a photorefractive LiNbO₃ storage crystal. In order to encrypt data, random phase multiplexing is added to the system. We proof that the combination of deterministic and random phase code multiplexing is possible with low cross-talk and take advantage of this technique for an extremely secure data encryption. Moreover, the potential of phase-code multiplexing to realize arithmetic operations is exploited for data encryption purposes.
