Medico-legal records contain critical information that bridges healthcare and law, including patient medical histories, treatment records, forensic reports, and legal case data, and managing these records efficiently is essential to ensure security, accuracy, and accountability. Traditional record management systems often rely on manual processes or basic digital storage solutions, which are prone to slow search times, weak encryption, limited access control, and inadequate auditability, leading to potential data breaches, unauthorized access, and delayed decision-making. CareChain addresses these challenges by integrating advanced technologies to provide a secure, transparent, and efficient management solution. The system utilizes B-Tree indexing for rapid and organized data retrieval, Key-Policy Attribute-Based Encryption (KP-ABE) to restrict decryption to authorized personnel based on predefined attributes, and Role-Based Access Control (RBAC) to enforce role-specific permissions for doctors, lawyers, administrators, judges, and patients. Additionally, Blockchain-based logging records all interactions with the records, including creation, modification, access, and deletion, ensuring a tamper-proof, immutable audit trail for transparency and accountability. By combining these technologies, CareChain minimizes manual effort, accelerates search and retrieval, prevents unauthorized access, and maintains data integrity. This solution empowers healthcare institutions, legal authorities, and patients with a robust, reliable, and trustworthy framework for secure management of sensitive medico-legal records.
