摘要：

This study introduces a new anti-counterfeiting method of packaging and printing. Based on CCD (Charge Coupled Device) detection, it changes the dot area to realize hidden information embedding into the halftone image which generated by own separate color program. After print and scan, CCD gain the scan image, combined with program to realize information extracting. The experiment results show that: this method has high speed and accuracy in embedding and extracting information. The function of prevent copy is good. This method can be widely used in packaging and printing anti-counterfeiting.
