The characteristics of digital watermarking technology in the anti-counterfeiting of printed matter
The application of digital watermarking technology in printing or printing has many characteristics. It completely renews the traditional concept of anti-counterfeiting of printed matter. From a technical point of view, when designing software and algorithms, we need better robustness and resistance to attack, and we also need to meet the following special properties:
â‘ Visual invisibility. The visual invisibility of the image in the print.
â‘¡Machine readable. Can be stand-alone or network authentication.
â‘¢ Robustness against nonlinearity. A / D, D / A conversion, including nonlinear quantization distortion and spatial aliasing.
â‘£Resist against rotation, scaling and cutting attacks. The position of the printed product is not correct, and rotation and shearing may occur. Both printing and inspection may produce scaling changes.
⑤ Resist color conversion and file format conversion. RGB, CMYK, BITMAP, GRAYSCALE and other format and color conversion, including color distortion (color distortion during printing and scanning, aging or wear in use, etc.).
â‘¥ Confidentiality. Can be combined with cryptography to enhance security.
⑦ Capacity of watermark. Consider with invisibility and robustness.
⑧Anti-counterfeiting technology can be upgraded gradually. Only continuous upgrades are possible to effectively prevent counterfeiting.
⑨No special requirements for printing equipment.
