Abstract
The present disclosure relates to monitoring processes. A processor creates a numerical representation of a nominal operation of the process. The processor then encrypts the numerical representation using homomorphic encryption to determine an encrypted numerical representation that blocks access to the numerical representation but allows calculations on the numerical representations. The processor proceeds by creating smart contracts on a blockchain platform using the encrypted numerical representation as a first input to the calculations of the smart contract. Next, the processor attempts execution of the smart contract using the current operation of the process as a second input to the calculations of the smart contract. The execution of the smart contract generates an output result by performing the calculations on the encrypted numerical representations. Based on the output of the execution of the smart contract, the processor finally determines that the current operation is outside the nominal operation.
