IBM Watson Health to launch blockchain-powered Digital Health Pass

IBM Watson Health has launched the IBM Digital Health Pass, a tool built on IBM blockchain technology that allows users to share their verified health pass, including COVID-19 test results, without exposing the underlying data. The tool aims to help individuals return to work or school while protecting their privacy and health. The health pass is verified against the blockchain for authenticity and validity. Other companies, such as CommonPass, are also exploring digital health passports for travel purposes.
