Enhanced Encryption Techniques for Secure Watermarking in Cloud-Based Image Sharing

The proliferation of cloud-based platforms for image sharing has amplified the need for secure and efficient data protection mechanisms. This paper introduces an advanced encryption framework tailored for watermarking in cloud environments. By leveraging Python-based implementations of cutting-edge cryptographic techniques, such as homomorphic encryption and elliptic curve cryptography, the proposed system ensures data confidentiality, integrity, and authenticity. The integration of reversible visible watermarking with enhanced encryption guarantees secure embedding and retrieval of ownership or authentication information without compromising image quality. Performance analysis demonstrates the framework's robustness, computational efficiency, and compatibility with cloud-based storage and retrieval systems, making it a viable solution for secure multimedia communication.
