ABSTRACT:
The stress-wave activity produced by the interaction between a writing instrument and a surface during the generation of a given piece of handwriting on the surface is detected and stored. The stress-wave activity produced by a subsequent generation of the given piece of handwriting is then compared with that produced by the initial piece of handwriting in order to determine whether the initial and subsequent handwriting pieces have a common author.
