Technical Examples

A digital pen-based application form filling system with a modification prevention function, which eliminates a possibility that digital information initially written in digital paper using a digital pen may be modified deliberately or accidentally. The system prints a new fine pattern over areas in already written digital paper whose contents one wishes to protect against being modified. This printing adds a fine pattern to an original dot pattern already present on the digital paper to make it theoretically impossible to enter information into these areas using the digital pen.
