Enhancing Medical Data Privacy and Security in Wireless Networks Via Smart Card and QR Code

This paper presents an approach to improving medical data accessibility and security in healthcare systems using QR codes and smart cards. As medical data continues to grow rapidly, traditional storage methods— primarily hard copies of case records stored in hospitals—are becoming increasingly inefficient. Our proposed Health-Care Portal system introduces a streamlined solution by generating a unique QR code and smart card for each patient, linking to their comprehensive medical history and treatment details. This system incorporates features such as clinical operation management, case records, complaint information, and secure access to patient data. By integrating QR codes and smart cards, healthcare providers can quickly retrieve essential information, enhancing both operational efficiency and data security. This approach ensures that critical medical information is accessible in real-time while upholding high standards of patient privacy, making it highly applicable for modern healthcare environments.
