PURPOSE:To provide an original copy processing technique through which a third party can spot the alteration of the copy easily, if he pays normal attention to it. CONSTITUTION:A complicated pattern consisting of characters and fine continuous patterns of an original copy incorporated together through the drawing of the fine continuous patterns stacked over the other on the original copy. Therefore, it is impossible to alter the original copy without disordering the fine continuous patterns even by a single character or figure. |
