Crystal Dzebu, Bernard Adjei Buckman, Evans Boye . A Robust Privacy-Preserving Architecture for Image Copyright Authentication based on the Blind Watermarking Approach and Elliptic Curve Cryptography. International Journal of Computer Applications. 186, 55 ( Dec 2024), 53-60. DOI=10.5120/ijca2024924278
This paper presents an Image Copyright Protection and Authentication System (ICPAS) that performs secure digital watermarking for image identification, authentication, and copyright management. The system introduces a hybrid RGB-YUV transposition blind watermarking approach, combining discrete wavelet transform (DWT), discrete cosine transform (DCT), Arnold transform, and Elliptic Curve Diffie-Hellman (ECDH) key exchange. This method ensures robust watermark embedding and extraction, achieving high imperceptibility and resilience against attacks such as JPEG compression, blurring, cropping, and zoom. Experimental results demonstrate the system's effectiveness, with high peak signal-to-noise ratio (PSNR) and normalized correlation coefficient (NCC) values, validating its ability to protect image integrity and authenticate copyrights. The system architecture is designed for scalability and security, integrating key and license servers to ensure privacy and efficient data handling.
