Holographic breakthrough boosts data encryption and storage

Using optical technologies and light-based sources such as lasers, it is possible to achieve far superior results than traditional magnetic storage methods, scientists from Nagaoka University of Technology and University of Hyogo explained.

The holographic technique is of particular interest as it allows the registration, transformation and manipulation of the spatial structure of light wave fronts, the new paper, by researchers Akira Emoto, Hiroshi Ono and Nobuhiro Kawatsuki explained.

The study outlines how a matched filter technique allows the spatial correlation of two optical images for pattern classification or detection. The scientists report that greater study is required into this technique but promise that it points to a new method for fast, efficient storage of "incredible amounts of data with high levels of security encryption."
