Abstract

An addition of Electronic Healthcare Records (EHRs) along with watermarking and blockchain technology has opened new avenues for assured and efficient data managing in healthcare systems. The present paper explores an innovative framework for leveraging EHRs in secure and robust multiple image watermarking using blockchain technology. The proposed approach embeds imperceptible watermarks into medical images to enhance authentication, copyright protection, and traceability, addressing critical concerns of data integrity and unauthorized access into healthcare. Blockchain technology exists employed for store watermarking and metadata securely, ensuring tamper-proof verification and decentralized control. The system uses advanced cryptographic techniques and adaptive watermarking algorithms to achieve high robustness against attacks such as compression, noise, and geometric transformations. Comprehensive experiments validate the efficiency of the presented method, demonstrating its developing towards protect sensitive medical data, foster trust among stakeholders, and support the scalability of modern healthcare ecosystems. This research highlights a transformative pathway for integrating watermarking with blockchain technologies to strengthen the security and reliability of EHR systems.
