To bolster its defenses against forgery attacks, Gaussian Shading can implement additional security measures. One approach is to introduce encryption techniques to protect the watermark information during embedding and extraction processes. By enhancing the encryption algorithms used in the watermark diffusion and randomization steps, Gaussian Shading can fortify the integrity of the watermark against malicious tampering. Furthermore, incorporating authentication mechanisms and digital signatures can provide an added layer of security, ensuring the authenticity and traceability of the watermarked content.
