Video-Based Data Transfer for Document Authentication

Since the development of the first computers (and even before), there is a steady growth of available digital data and information. E.g. estimations say that the amount of digital information will grow about 50 percent in the year 2012 compared to the year 2011. Following the rising availability of digital data, there is also an inherent need for methods to transport these data, as the data is to be used and processed at some time. Many methods and channels are available for the transportation of these digital data. This research work presents the foundation work for the new microIDENT coding (2D-code) for document authentication. As a coding for document authentication it is one objective of microIDENT, to increase the difficulty of copying a document without the destruction of the coding. The new coding requires, in comparison to other 2D-codes, less space when printed. This is achieved by omitting some of the features that are used in standard 2D-codes for stabilisation and that are necessary in a mobile environment. In addition, we will also show that this new 2D-code delivers, under certain constraints, a better performance than other 2D-codes.
