<p>A system enabling automatic identification of a hand written signature is provided. A specimen signature is written with a special pen which will provide as output? signals representing the direction which that pen is moved to produce that signature. This information is converted into direction per unit of time which is stored at a particular address in the memory of a data processing machine. For verification of such a signature, an individual indicates to the machine, in any suitable manner, the address where his signature is stored in memory, and then proceeds to write his signature again with said pen. The direction per unit of time information which is generated at this time, is compared with the direction per unit of time read out of memory. If there is sufficient correlation, the machine indicates the signature is acceptable. If not, it indicates the signature is not acceptable.</p> |
