Share Chennai: Indian Institute of Technology Madras researchers have developed ‘BlockTrack’, a first-of-its-kind blockchain-based secure medical data and information exchange system for a mobile phone-based application. This system is currently being field-tested at IIT Madras Institute Hospital. The project has been undertaken with CSR support from Infosys originating during the height of the COVID-19 pandemic last year. BlockTrack aims to securely digitize healthcare information systems while ensuring the protection of sensitive personal information and medical records by decentralizing the control and ownership of patient data, through a blockchain-based innovation. The BlockTrack innovation is now protected through a provisional IP filed with the Indian Patent Office.
