This paper presents a new anti-copying methode for hard copy documents. The approach protects the document and its content from unauthorized copying and forgeries, while using ordinary paper and ordinary printer. The paper copy is protected against copying as the photocopy version will appear differently when compared to the authorized printed original hard copy using Human Visual System . The anti-copying pattern created through pointillism with a halftone cell and a spot. The proposed method is useful for unauthorized copying and forgeries with high-resolution scanners and photocopiers.
