摘要： Method and device for producing and storing personal identification

information, allowing a person to move a light pen (14) on a CRT screen (12) describing apattern corresponding to the signature. A CRT controller (17) provides a representationof an approximate position of character and a high definition sensor (20) comprising acounter (24) which counts the pulses in synchronism with the point positions, provides amore accurate representation the position of the light pen (14). The approximaterepresentation and more accurate representation are combined and a calculation of theaverage and compression of the resulting data to obtain a vector representing thesignature, which vector is stored. A visible trace of the signature can be displayed on theCRT (12). Alternatively, a transparent image of the signature is first formed and the imageis placed on the CRT screen (12) to be followed by the light pen (14).
