How can you be 100% sure that...
(1) The citizen who’s associated to an electronic immunity passport or risk-free certificate showing a negative test to Covid or a positive test to immunity is who he says he is.
(2) The test results have not been compromised while stored in a database?
The reality is that obtaining personal data from someone via the dark web or from phishing is kind of business as usual for the average hacker out there.
1Kosmos realized those two key issues represented a unique opportunity to engineer the concept of electronic certificate differently:
First, the utilization of advanced Biometrics to secure the identity of the citizen who shares his Covid test results electronically with an employer is key. A hacker cannot indeed reproduce and therefore compromise the analysis and result of a liveness test, for example.
Second, a decentralized database like Blockchain that is virtually uncompromisable and that initiates peer-to-peer transactions while ensuring the immutability of the data stored is the answer to risks associated with systems hacking.
The combination of advanced Biometrics to enroll and authenticate an individual and Blockchain technology to guarantee data is securely stored while facilitating exchange between the data owner and an entity (business, airlines) seems to be the only viable option at the moment.
To create trust in the relationship between a patient and his or her healthcare provider concerning the access and update of the patient’s medical history is essential.
Leveraging Blockchain entails storing a patient’s medical history in the Blockchain and the same patient being able to grant permission to a doctor to request the data, prior to consultation via the execution of a smart contract.
The immutability of the Blockchain is leveraged to record all patient–provider interactions. Once a healthcare provider creates a record, the source is verified and its viewing permissions are authorized by the patient and stored in the network. The document can never be modified, creating trust between all parties involved.
Therefore, Blockchain can improve the accessibility and security of the patient’s information and build an ecosystem in which patients manage their care and medical information.
