摘要

PURPOSE: A secure document for preventing counterfeit/alteration and a counterfeit/alteration distinguishing tool are provided to form counterfeit/alteration preventing images of a recognizable array type on a secure document, thereby reducing counterfeit/alteration possibility of the secure document. CONSTITUTION: A case(220) receives a secure document. An array type micro lens is formed in the case. When the secure document is inserted into the case, a detection unit(210) enlarges an array type forgery/alteration preventing image of the secure document that a user can not recognize. The detection unit detects whether the secure document is forged/altered by the enlarged forgery/alteration preventing image. The detection unit is formed in a set area of the case.
