Digital watermark anti-counterfeiting technology for industrial-grade PE plastic bags

Digital watermark anti-counterfeiting technology is a technology that embeds specific information into digital media in an invisible way. In the application of industrial-grade PE plastic bags, this technology embeds anti-counterfeiting information into the packaging pattern or logo of the plastic bag to achieve product anti-counterfeiting verification.
Technical features
High concealment: Digital watermarks exist in a visually invisible form. The difference between watermarks without watermarks and watermarks cannot be distinguished under natural light and external light sources. It can only be extracted and verified through dedicated detection equipment or software.
Strong technical exclusivity: Digital watermark technology is difficult to imitate. It is relatively convenient for users to embed and detect watermarks. In addition, a set of dedicated software is designed for each product, and the software is easy to change and upgrade.
Good robustness: Digital watermarks can resist various physical and geometric distortions, including image compression, filtering, scanning and copying, noise pollution, etc., to ensure the stability and reliability of anti-counterfeiting information.
High confidentiality: Watermark information has the concealment implicit in the media, and can be combined with cryptographic private key and public key control detection to enhance the anti-counterfeiting effect.
Application scenarios
In the production process of industrial-grade PE plastic bags, digital watermark anti-counterfeiting technology can be applied to the following scenarios:
Packaging pattern: embed anti-counterfeiting information into the packaging pattern of the plastic bag, so that each product packaging has a unique anti-counterfeiting mark.
Product label: attach a special anti-counterfeiting label to the PE plastic bag, and embed digital watermark information in the label to quickly verify the authenticity of the product.
Supply chain management: in each link of the supply chain, the authenticity and circulation of the product are confirmed by detecting watermark information to prevent counterfeiting and substitution.
