        abstract = {Traditional cloud-based healthcare systems face challenges in ensuring data security, privacy, and efficient data management. The proposed Cloud-Assisted Decentralized Privacy-Preserving Framework (CA-DPPF) integrates Blockchain, InterPlanetary File System (IPFS), and Elliptic Curve Digital Signature Algorithm (ECDSA) to address these issues. It enables tamper-proof and decentralized storage for patient records, incorporating RSA encryption for privacy. Two extension concepts enhance the system: adopting ChaCha20 encryption for faster, lighter, and more secure data encryption and introducing a rating module for patients to evaluate doctors, ensuring transparency and credibility. These innovations ensure robust security, reduced computational overhead, and enhanced decision-making processes, making CA-DPPF a scalable, secure, and efficient solution for modern healthcare environments.},
