At its foundation, contact tracing is a simple and intuitive exercise. If a person tests positive for any Communicable Disease (eg-Covid-19), the testing center or healthcare facility that provided the test notifies the local public health department. The infected person is then contacted by the health department, who requests that they name people they have come into contact with for a specified period of time previous to the test. Following that, the health department contacts such individuals to seek a test. If any of those patients test positive, the procedure is repeated until all of the patients tested negative. Patients who have tested positive for a disease are frequently advised of the length of time they must remain in quarantine and are formally notified after they have "recovered."To maintain the confidentiality of student health records, blockchain technology can anonymize patient records and provide additional levels of security. The name or identity of students cannot be identified by merely browsing or querying the blockchain since test results are linked to a student's public/private key instead of their university ID. Furthermore, because all blockchain entries are cryptographically signed, bad actors cannot change a record without invalidating all subsequent records. Using identity access management software, further controls can be introduced to limit what information an individual can read on the blockchain.
