Abstract
Disclosed herein is a forged seal imprint checking method which includes a step ST-101 of generating a reference seal imprint from a genuine seal (ST-110) and a step ST-121 of comparing a compared seal imprints with the reference seal imprint to calculate characteristic values of the compared seal imprint with respect to the reference seal imprint (ST-140). According to experimental results, forged seal imprints obtained by seals forged by etching a zinc plate or a resin plate can be recognized and forged seal imprints generated by seals forged through computer copy can be also recognized. Accordingly, an objective basis on which it can be determined whether seal imprints on documents are forged in civil and criminal cases can be provided to prevent errors which may be generated when seal imprints are inspected with the naked eyes or microscopes.
