Optical image correlation in photorefractive mesogenic composites
"Computer industry analysts estimate that some 60 percent of all corporate data exists only on desktop and laptop computers, " said Walter Scott, CEO of Acronis. "Incorporating Acronis True Image with New Mexico Software backup server is the ideal solution to capture that corporate data and ensure that it is not lost. While traditional server backups are effective for protecting server data, every company should have a combination of server and workstation backup plans."

Gordon Brown has renamed the DTI the Department for Business, Enterprise and Regulatory Reform (DBERR) to reflect its focus on the reduction of red tape and a commitment to entrepreneurship. February 2007 Businesses are 'struggling under weight of computer data' Britain's businesses are struggling under the weight of computer data, research shows. According to a study by PMP Research, commissioned by the Evaluation Centre, more than four out of five firms have reported a massive increase in their data storage requirements.

The rapidly developing digital age demands greater processing power, data storage and data encryption for computer based technologies. Recent developments point towards optical information processing as a great leap forward.
We use secure technology and your data is processed in accordance with the Federal Data Protection Act. The Security Server Software (SSL) used by us is an encryption process which is recognised on the Internet. The encryption of your data comprises the Login data, the complete customer data including the credit card data and the booking data.

Know how data is transmitted between the client and the server and the different servers (which communicate internally). 6. Know our internal data packet structure. 7. All data streams are encoded using 128 bit encryption, the same encoding done by online banking. They would need to hack this encryption as well, first to find out the internal data packet structure and then to send data.

These optical technologies use light based techniques and sources such as lasers to achieve results better than traditional electronic computing and more conventional magnetic based storage methods.

Holograms have been shown to be able to store, write and read massive amounts of data. These holographic data storage techniques can also be accessed at high speeds.

The holographic technique is of particular interest as it allows the registration, transformation, and manipulation of the spatial structure of the light wave fronts. This paper, by Japanese researchers from Nagaoka University of Technology and University of Hyogo, Akira Emoto, Hiroshi Ono and Nobuhiro Kawatsuki presents a matched filter technique which allows the spatial correlation of two optical images for pattern classification and/or detection.

The results demostrate optical image correlation by means of Fourier transform holograms in the region of Raman-Nath diffraction on to photorefractive mesogenic composites film. The reconstructed image produced is readily recognisable as common numerals. Greater study is required into this technique but it points to a new method for fast, efficient storage of incredible amounts of data with high levels of security encryption.
