Image Copyright Protection Using Quantum Watermarking

Given the growing risks of digital asset manipulation and forgeries, maintaining multimedia integrity is essential in modern computing. Even though traditional watermarking techniques work well, they are nevertheless susceptible to intrusions. We suggest a Quantum-Based Watermarking System (QBWS) to solve this problem, combining entropy analysis, Discrete Cosine Transform (DCT), and quantum security concepts for improved security. Entropy-driven anomaly detection and quantum-based secure watermark embedding are the two security layers that our system uses. To stop unwanted dissemination, an automatic degradation mechanism warps the image whenever manipulation is detected. Furthermore, an open authentication ledger uses a PDF security report to document integrity verification results. The unique feature of QBWS is that it combines conventional watermarking with quantum techniques to provide active tamper deterrence as opposed to passive verification. Higher resilience against cyberattacks is guaranteed by this method, which also creates a strong, open, and safe multimedia security architecture.
