Detecting cashback and other related reimbursement frauds using blockchain technology

摘要

Methods, apparatus, and processor-readable storage media for detecting cashback and other related reimbursement frauds are provided herein. An example computer-implemented method includes implementing, in response to a transaction between a user and a first enterprise, a block in a blockchain network, wherein the block comprises transaction-related information comprising reimbursement-related data and cryptographic information; generating a smart contract in conjunction with the block, wherein the smart contract comprises a software protocol pertaining to carrying out a reimbursement process, related to the transaction, between the user and a second enterprise; executing the smart contract in response to an indication that transaction-related information provided to the second enterprise by the user has been verified against the transaction-related information contained within the block; and modifying, in response to the execution of the smart contract, a status identifier of the block, wherein the modification of the status identifier reduces subsequent access to the block.
