Creating Digital Watermarks in Bitmap Images Using Lagrange Interpolation and Bezier Curves

Area of Science:

• Computer Science
• Information Security
• Digital Image Processing

Background:

• Digital watermarking is crucial for copyright protection systems.
• Existing methods embed hidden markers resistant to transformations.
• Steganalysis techniques detect hidden data within digital media.

Purpose of the Study:

• To introduce a novel digital watermarking method for bitmap images.
• To evaluate the robustness of the proposed method against steganalysis.
• To compare the proposed method with existing image embedding techniques.

Main Methods:

• Embedding digital watermarks using Lagrange interpolation and the Bezier curve formula for five points (LIBC5).
• Employing the RS (Rich Statistics) method for steganalysis to detect hidden messages.
• Conducting experimental analysis to determine the stability and resistance of the LIBC5 method.

Main Results:

• The developed LIBC5 method proved resistant to RS steganalysis.
• LIBC5 demonstrated improved robustness against quilting attacks compared to the INMI method.
• Experimental results confirm the effectiveness of LIBC5 in protecting data.

Conclusions:

• The LIBC5 stegosystem offers a viable solution for protecting confidential data and copyrights.
• The method's resistance to steganalysis makes it suitable for secure information embedding.
• LIBC5 represents an advancement in robust digital watermarking techniques.
