Area of Science:

Computer Science
Digital Media Security
3D Graphics

Background:

Digital watermarking is crucial for copyright protection and data security.
Existing methods often lack efficiency or robustness for 3D objects.
Blind watermarking allows extraction without the original data, enhancing practicality.

Purpose of the Study:

To develop a rapid, blind watermarking method for 3D objects.
To embed QR code images into 3D models with high imperceptibility and transparency.
To evaluate the robustness of the watermarking technique against various transformations.

Main Methods:

The method operates in the spatial domain, converting 3D object triangles to 2D coordinates.
It modifies the third vertex of each triangle to embed QR code pixels.
Extraction is performed blindly, without requiring the original 3D object or QR code.

Main Results:

The watermarking algorithm demonstrated high imperceptibility and transparency.
Robustness was validated against rotation, scaling, and translation attacks.
The method achieved excellent execution time and successful QR code extraction.

Conclusions:

The proposed method offers an efficient and robust solution for watermarking 3D objects.
It successfully embeds QR codes with minimal visual distortion.
This technique is suitable for applications requiring secure and imperceptible 3D data embedding.
