COGNIX – A Cognitive AI Agent Platform For Real-Time Business Intelligence And Automation

The increasing digitization of healthcare systems has led to the widespread adoption of electronic health records (EHRs), raising concerns about data security, privacy, and interoperability. This paper proposes a blockchain-based secure health record management system designed to ensure the confidentiality, integrity, and accessibility of patient data. By leveraging the decentralized and tamper-resistant nature of blockchain technology, the system enables secure storage and sharing of medical records among authorized stakeholders such as hospitals, doctors, and patients. Smart contracts are utilized to enforce access control policies and automate data-sharing permissions. Additionally, cryptographic techniques are integrated to protect sensitive information from unau-thorized access and cyber threats. The proposed framework enhances transparency, reduces the risk of data breaches, and eliminates the need for a centralized authority. Experimental analysis demonstrates improved data security and efficient record management compared to traditional systems. This approach offers a reliable and scalable solution for modern healthcare environ-ments.
