3. PREAMBLE OF THE DESCRIPTION
SecureMed is a blockchain-based platform designed to securely manage Electronic Health Records (EHRs) while addressing the vulnerabilities of traditional systems, such as data breaches, unauthorized access, and tampering. By leveraging blockchain's core features of immutability and transparency, SecureMed ensures that only authorized users-such as patients, doctors, and insurers--can access sensitive data. The system integrates RFID/NFG authentication, enabling healthcare professionals to securely and quickly access patient records through smartwatches equipped with unique identifiers, thereby eliminating the need for manual logins and reducing the risk of credential misuse. For patients who do not use wearables, barcode or QR code identification ensures that their data can still be securely retrieved using other devices. This combination of blockchain technology and modern authentication mechanisms not only enhances data security but also streamlines clinical workflows, reduces operational delays, and provides a scalable, future-proof solution for efficient EHR management across healthcare settings.

4.6 Brief Description of the drawing:
Fig l: Flow diagram of SecureMed
1. User Registration: The process begins with the user (either a patient or healthcare professional) registering into the system, where they are assigned an RFID or QR code for future identification purposes.
2. Check-In: The user scans their assigned RFID/QR code when accessing or interacting with a healthcare provider or device. This action triggers the system to check for valid identification and initiates the process for accessing EHRs.
3. Audit Log: Simultaneously, the system updates the audit log, recording the user's interaction with the system. This ensures transparency and traceability of all access attempts, critical for security and compliance.
4. Verification: The system communicates with the healthcare provider to verify the authenticity of the user's identity.
If the verification fails, the system blocks access to EHRs and prevents unauthorized entry.
If the verification succeeds, the healthcare provider is granted access to the EHR system.
5. EHR Access: Once verified, the healthcare provider can request to view or update the patient's EHR. The user (patient) is also notified of this request for their records.
6. Update or Action Denied: Based on the user's request or permissions, the provider can either successfully update the patient's EHR or be denied access if the necessary authorization is not granted.

Fig 2: Design of the SecureMed
The design explains details a Patient Management System using technologies like RFID and Blockchain. Here's a brief explanation of the flow:
1. Patient Registration: Patients are registered and assigned an RFID tag.
2. RFID Scanning & Profile Linkage: The patient scans their RFID, linking their profile for quick check-in.
3. Health Record Access: The system queries the blockchain, authenticating through
MetaMask If authenticated, the patientfs Electronic Health Record (EHR) is retrieved and presented.
4. Access Logging &, Record Modification: If necessary, logs are created, and records are modified. Any modification triggers a smart contract

5. Request Validation: The request is validated before executing updates. If consent is required, the system checks for it.
6. Consent Handling: If patient consent is missing, the update or data sharing is denied unless new consent is obtained.
4.7 Detailed Description of the drawing:
The drawings presented illustrate a multi-layered, technology-integrated Patient Management System (PMS) designed for efficient, secure, and automated handling of patient registration, record management, and health data sharing, leveraging RFID, blockchain technology, and smart contracts.
In the first step, the patient registration process involves assigning an RFID (Radio-Frequency Identification) tag to each patient. This RFID serves as the patient's unique identifier. Upon arrival, the patient scans the RFID tag using a dedicated terminal, which links the RFID to the patient's health profile in the system. A quick check-in process follows, which eliminates manual check-in processes and allows seamless access to patient details. Once the RFID is scanned, the system retrieves the patient profile from the backend, enabling the patient to proceed without manual intervention. The system uses an encrypted barcode mechanism for added security during profile linkage, ensuring that sensitive information is protected during the registration phase.
The next stage in the workflow focuses on accessing health records. The system integrates blockchain technology to enhance the security and transparency of patient data. After profile linkage, the system queries the blockchain to retrieve the patient's Electronic Health Records (EHRs). Before any data is accessed, the system requires authentication via MetaMask, a popular cryptocurrency wallet used for blockchain applications. This ensures that only authorized personnel or entities can access the patient's data. If authentication is successful, the EHR is retrieved from the blockchain and presented to the healthcare provider. If the authentication fails, access is denied, ensuring robust security measures are in place to protect patient data from unauthorized access.
Once access to the EHR is granted, the system logs the access event and allows for the modification of records as needed. Any modification or update triggers a smart contract that ensures all actions are logged on the blockchain and are auditable. The smart contract automatically handles the request validation process, ensuring that only valid, authorized : modifications can proceed. If the request is validated, the modification is executed, and the | updated information is stored back onto the blockchain. In cases where the request does not pass validation, the update is denied, and the healthcare provider is notified. The system also incorporates a patient consent mechanism, ensuring that data sharing or updates are only executed if explicit patient consent has been obtained. If the patient's consent is missing, the system will deny sharing or modifications and prompt for consent, ensuring compliance with privacy regulations and legal standards. If consent is granted, the system proceeds to share the data securely.
The two diagrams work together to depict this integrated patient management system. The first diagram emphasizes the registration, RFID linkage, and check-in process, while the second diagram focuses on the blockchain-based retrieval and secure handling of EHRs, smart contracts for record modifications, and patient consent mechanisms. Together, they present a robust, secure, and efficient solution for patient data management that leverages cutting-edge technologies to improve both security and usability for healthcare providers and patients alike.
