$ITMC News - ITOCO's new patent-pending Immutable

$ITMC News - ITOCO's new patent-pending Immutable Virus Test Result Verification System (USPTO Provisional Patent Application #63062398) combines the necessary elements of "an application which combines public key cryptography with biometric reading technology and the ability to write data to and retrieve data from a blockchain that is installed on a mobile computing device, a virus testing machine that processes a biological sample to test for a specific virus to return a positive or negative result, while associating that sample and result with an identity provided by the application and writing the results to a blockchain, a blockchain with deployed smart contract logic that verifies that only approved virus testing machines can write new data to the blockchain and that stores identity information that is written to it by the application and associates immutable test results with those identities, and a controlling application that deploys the smart contract logic code to the blockchain, and adds public key addresses for verified virus test machines that allow them to write virus test data to the blockchain, in a complete system that provides immutable virus test verification".
