Blockchain for Secure 3D Model Sharing Among Healthcare Providers Exploring Decentralized Methods to Prevent Unauthorized Access to Medical Models

Secure dissemination of 3D medical models across healthcare institutions is critical for advancing diagnostic precision, preoperative planning, and therapeutic interventions. Traditional centralized data-sharing frameworks are plagued by vulnerabilities including unauthorized access, poor traceability, and system-wide failures. This paper introduces a decentralized architecture, underpinned by blockchain, smart contracts, and the InterPlanetary File System (IPFS), to address these challenges. The proposed framework ensures data provenance, integrity, and HIPAA compliance while enabling cross-institutional collaboration through secure, transparent, and programmable access control mechanisms.
