Abstract: PURPOSE: The forgery detection system of a security printed material and a detection method thereof are provided to create learning model for detecting forgery by performing machine learning with extracted feature points. CONSTITUTION: The forgery detection system of a security printed material comprises an image transformation part(10), a feature point extracting part(20), a machine learning part(30), and a forgery detection part(40). The image transformation part changes prints into a digital. The feature point extracting part extracts the feature point of the digital image. The machine learning part performs machine learning using the feature points. The forgery detection part detects the forgery of a printed material from a machine learning result.
