Methods to prevent image watermarks from being maliciously removed by others are:

1. Increase the complexity of the watermark and expand the scope of the watermark. As shown below, there is no way to remove such a watermark from a technical point of view.

2. Use smaller pixels when publishing sample images. In this way, even if the watermark is removed from the sample image, the pixels of the image are too small and cannot be used by pirates.

3. Apply for copyright protection. The application process is as follows:

Documents required for corporate and individual applications

Corporate application materials:

1. Trademark pattern (black or color)

2. Scanned copy of business license;

3. Contact person, phone number, shipping address, postal code;

4. Selected products/categories and services.

Personal application information:

To apply for registration of a general trademark in the name of an individual, you need to provide:

1. Trademark drawing (black or color)

2. Scanned copy of self-employed business license;

3. Scanned copy of front and back of personal ID card;

4. Contact person, phone number, receiving address, zip code.

After applying for copyright protection, if the copyright is infringed, you can file a lawsuit to recover the economic losses caused by the removal of the watermark.
