Patient Health Record System using Blockchain Technology

Abstract: The integration of blockchain technology into patient health records (PHRs) presents a transformative solution for healthcare systems worldwide. This abstract outlines the key benefits and objectives of utilizing blockchain in EHR systems. Blockchain ensures data securityand privacy through cryptographictechniques, offering patients greater control over their health information. It establishes a tamper-proof, auditable ledger, guaranteeing data integrityandimmutability. Moreover, smart contractsstreamlineadministrativeprocesses,reducingcosts and errors. Consent management tools allow patients to control data access, ensuring compliance with regulations like HIPAA and GDPR. Thisinnovationfostersinteroperabilityamonghealthcareproviders,facilitatingseamless data sharing and improving care coordination. It empowers healthcare researchandanalytics, securely sharing data while preserving privacy. Standardized data formats enhancecompatibilityamong different PHR systems.
