    Introduction.

    Optics express·2009

    Area of Science:

    • Digital image processing
    • Information security
    • Computer vision

    Background:

    • Digital watermarking is crucial for copyright protection and data integrity.
    • Existing methods face challenges with robustness against common image manipulations.
    • The Discrete Cosine Transform (DCT) domain offers potential for robust watermark embedding.

    Purpose of the Study:

    • To propose a novel image watermarking algorithm utilizing constraints within the DCT domain.
    • To enhance watermark robustness against JPEG compression and filtering attacks.
    • To introduce two distinct constraint rules for watermark embedding and detection.

    Main Methods:

    • The algorithm involves two stages: signature casting (embedding) and signature detection.
    • Pixel blocks are selected based on predefined parameters.
    • DCT coefficients within selected blocks are modified using either a linear constraint or circular detection regions.

    Main Results:

    • The proposed watermarking algorithm demonstrates resilience against JPEG compression.
    • Watermarks embedded using the algorithm are also resistant to filtering attacks.
    • Two novel constraint rules were successfully applied for watermark embedding and detection.

    Conclusions:

    • The developed DCT-based image watermarking algorithm offers robust protection for digital images.
    • The algorithm's resistance to JPEG compression and filtering makes it suitable for practical applications.
    • The proposed constraint rules provide effective mechanisms for watermark embedding and detection in the DCT domain.
