Security Based Variable Holographic Data Encryption using Spatial Light Modulator
Journal Title: UNKNOWN - Year 2015, Vol 4, Issue 4
Abstract
Holographic data storage(HDS) has been considered as a promising data storage technology.The level of security can be increased, if it is possible to record variable data, such as 1D and 2D barcode, in the same hologram. Then holograms will be different for each other provided the same general security features for all. This level security can also be verified by using a system, contain a laser source, detector array and barcode reader ,which will reduce counterfeiting. Also the difficulty in producing an original hologram which is expensive and time consuming can be overcome by mass produced replicas from the original which are relatively inexpensive.
