Abstract - In today’s digital healthcare environment, safeguarding sensitive patient information is a critical challenge, especially with the growing use of wireless networksfordatatransmission.Thispaperpresentsasecure and efficient healthcare data management system that integratesSmartCardtechnology,QRcodeencryption,and Aadhar-basedauthenticationtoensureprivacy,accessibility, and rapid information exchange. The proposed system allows medical professionals to access encrypted patient records by scanning QR codes linked to smart cards, with identityverificationbackedbyAadharcredentials.Datais protected using robust encryption techniques like AES, ensuringconfidentialityduringwirelesscommunication.The systemisdesignedtosupportdiverseapplicationssuchas emergency services, remote consultations, prescription verification, and insurance processing. It also addresses technicalchallengeslikehardwarecompatibility,securedata synchronization, and user-friendly authentication. The developed platform uses Java, JSP, and MySQL, and was tested successfully through unit, integration, and systemlevel testing. With its scalable design and potential for integration with biometric systems and cloud-based services, this solution offers a future-ready approach to digitalhealthcaredatasecurity

1. INTRODUCTION
With the increasing digitization of healthcare services, protecting patient data has become a critical concern. Traditional systems often lack strong security, making medical records vulnerable to unauthorized access and misuse especially over wireless networks. This paper presentsasecurehealthcaredatamanagementsystemthat combines Smart Cards, QR code encryption, and Aadharbased authentication to ensure data privacy and secure access.
The system allows authorized users to access encrypted patientinformationthroughQRcodeslinkedtosmartcards, withstrong encryptionand identityverification.Designed for use in hospitals, emergency services, and remote healthcare,thesystemimprovesbothsecurityandefficiency.
Built using Java, JSP, and MySQL, the platform offers a
