1.2 Introduction to the software

This software is a digital watermark reading software equipped with mobile phone shooting and image imaging module, image processing module, digital watermark detection module, digital watermark anti-counterfeiting information identification module and anti-counterfeiting information result feedback module on the mobile phone; The digital watermark algorithm in this digital watermark detection module corresponds to the printing digital watermark embedding algorithm used to embed anti-counterfeiting information in advance. During operation, the mobile phone is used to take a video of the detected object containing the digital watermark, and the image processing, watermark extraction, and judgment of the authenticity of the detected object can be completed by running the digital watermark reading software, which has the outstanding advantages of accurate, fast and convenient to use.

The steps to read it are as follows:

the first step, use a mobile phone to shoot the carrier image such as paper to obtain the carrier image after shooting;

the second step, the obtained image is qualitatively and quantitatively analyzed, if the image quality does not reach a certain threshold, the next step will not be carried out, and the shooting will continue until a carrier image that meets the image quality threshold is captured;

the third step, the carrier image that meets the quality is effectively located in the range, and the image in the range is intercepted;

in the fourth step, the effective carrier image that meets the quality is processed by digital watermarking technology, and whether the image contains digital watermark anti-counterfeiting information is analyzed;

Finally, according to the digital watermark anti-counterfeiting information obtained after analysis, determine whether the image has undergone digital watermark anti-counterfeiting treatment, so as to identify the authenticity of the carrier.
