Advantages of digital watermark anti-counterfeiting technology:

1. As an identification mark, the watermark is hidden in the printed matter in a visually invisible form. It cannot be distinguished by natural light and external light sources without watermarking. The difference between the image and the watermarked image can only be detected through a proprietary detector or an ordinary scanner with supporting software

2. The technology has good exclusivity, high confidentiality, and can be classified Decentralized management. Digital watermarking has a high technical content and is difficult to imitate, but it is convenient for users to embed watermarks and detect watermarks. The technology itself has concealment hidden within the media, and can also be combined with cryptographic private key and public key control detection, making it compatible with other security technologies. In addition, this technology can also add multiple layers of confidentiality marks, so that people with different permissions can see different hidden contents.

3. Hidden watermarks can be unilateral numbers and random numbers, text information, images and even sounds. Users can add watermark information with different contents according to the different requirements of the protected items. The detection method can be whether there is a hidden watermark, or extracting the actual content of the hidden information from the printed matter.

4. The hidden watermark information continues to exist inside the printed matter at different events and locations. The principle is that the data with the identification mark is hidden in the printed matter itself or the printed image. It does not change due to the various places and people the printed matter passes through, and there is no possibility of leakage and diffusion in these links.

5. The addition of digital watermarks and the added content are random. The digital watermark hidden in each type of printed matter can be different, and the location of the watermark is also random. The technical master himself does not know the hidden location of the watermark. Such characteristics and changes make it difficult for forgers to forge. In addition, because the embedded logo is invisible, it is difficult to be discovered and counterfeited

6. Anti-counterfeiting technology is rapidly upgraded. According to the product characteristics, a set of special software is designed for each set of products. The software is easy to change and upgrade, so digital watermark technology is also constantly being upgraded and changed

7. Supply chain certification can be carried out. After watermarking is added to the image, it can be authenticated at nodes in the supply chain to identify whether it is a copy of the original, preventing forgery and product substitution

8. It can add value to the product. Digital watermarks allow image and text publishers and trademark owners to enhance customers' trust in their products, maintain the company's brand image, and protect tax and economic interests

9. Digital watermark anti-counterfeiting technology has no special impact on printing equipment requirements, making it difficult for pirates to detect their location. Users can add digital watermark information to their existing packaging and highly confidential designs during the printing process, which has the characteristics of high technical content and difficulty in counterfeiting. In addition, there is no need to change printing materials and equipment, increase printing costs, or initiate original designs. Confidential features can be embedded into the design of printed products through software processing, so its application prospects are promising and the economic benefits are great.
