Aadhar card is an Indian Government ID card that is issued to all Indian residents. It is one of the largest biometric databases in the world with over 1.28 billion enrollments thereby constituting the most ubiquitous ID card in India. With the additional features of QR code and biometric scanning, it forms an ideal database to be linked with the electronic health record. The health records of an individual currently in India is being maintained by the individuals. But most often they are misplaced, disorganized, incomplete or lost. This would force the clinician to assume or ascertain the current medical status by subjecting the individual to tests. Improving the quality of the medical and dental services rendered paves way for an integrated electronic health record. The common concerns arising from such a linkage is data management and data security. Big data management provides a systematic approach to maintaining such large data. The data security concerns can be addressed by employing a data controller in every hospital and a cell to inform the security breach, who can further take up legal penalties. Pseudonymisation, cryptography, audit trial, firewall, antivirus software, and cloud computing are some techniques that can be incorporated.
