The present invention relates to a method for verifying forgery for financial institution proof documents. The method according to the present invention comprises the steps of: transmitting, to a block chain retention server, transaction ID information corresponding to proof certificate-verifying transaction information if a request for proof certificate information to be provided to a customer is sensed, in a state in which the proof certificate-verifying transaction information generated by using the proof certificate information, to be provided to a customer, is recorded in a block chain retention server and transaction ID information corresponding to the proof certificate-verifying transaction information is managed; acquiring, from the block chain retention server, the proof certificate-verifying transaction information corresponding to the transaction ID information; comparing (i) a proof certificate index hash value used for comparison, acquired from the proof certificate information to be provided to a customer and corresponding to a request, with (ii) a proof certificate-verifying index hash value acquired from the proof certificate verifying-transaction information; and providing verification information generated with reference to the comparison result of the proof certificate index hash value used for comparison, and the proof certificate-verifying index hash value. |
