A user may claim to have not made or allowed a transaction and that the transaction was made in error. Where it appears the user has not authorized the transaction, the funds of the transaction are returned to the user, or are charged back. Systems and methods provide a way to confirm whether or not a transaction was actually authorized by the user, thereby settling a chargeback dispute for a previously executed transaction. The method comprises receiving the dispute regarding the transaction including associated transaction data, and retrieving a digital signature associated with the transaction data, the digital signature computed by signing the transaction data. The digital signature is then verified using a public key, wherein the public key corresponds to a private key stored on a mobile device. It is then determined whether or not the transaction is fraudulent based on a verification result of the digital signature. |
