BBACTFM (Blockchain Based Accurate Contact Tracing Framework Model) for Tourism Industry

ABSTRACT

Contact tracing is, at its core, a straightforward and logical operation. The testing facility or healthcare facility that performed the test notifies the neighborhood public health department if a person tests positive for any communicable disease (such as COVID-19, omicron). The health department then contacts the sick person and asks them to list any contacts they had for a predetermined amount of time before to the test. The health department then gets in touch with these people to request a test. The process is repeated until all of the patients have tested negative if any of those patients have a positive result. Patients who test positive for a disease are typically informed of how long they must spend in quarantine and are publicly notified after they "recover.” Blockchain technology can anonymize patient records and offer higher degrees of protection to maintain the privacy of tourist health details. Since test results are connected to a visitor's public/private key rather than their Personal ID, their name or identity cannot be determined by simply browsing or querying the blockchain. In addition, since every blockchain entry is cryptographically signed, malicious parties are unable to alter a record without also invalidating all future records. Additional controls can be added using identity access management software to restrict what data a user can read on the blockchain. The shortcomings of conventional contact tracing applications would be resolved by our proposed framework, dubbed BBACTFM (Blockchain Based Accurate Contact Tracing Framework Model for Tourism Industry). © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
