Abstract:
The present application provides a tampering verification system and method for financial institution certificates, based on blockchain. Whether or not there is tampering of a certificate in the watermark thereof is verified by comparing the contents of the certificate at the point of first being generated by a financial institution and the point of client issue. Also, in a client certificate registration process, based on blockchain, a means for compressing and registering transaction information comprising client certificate information minimizes the generation of traffic, reduces network overload, and verifies whether there is tampering of certificates of clients of a financial institution, periodically in a predetermined cycle, thus monitoring whether a certificate is being tampered due to hacking.

Claim (Index 9):
The method of  claim 7 , after the step of S 130 , further comprising:\n a step S 131  of the authentication-managing server, if said one of the anchoring conditions is met, extracting all of previous transaction IDs that have been stored in a verification DB before said one of the anchoring conditions is met, and transmitting each of the previous transaction IDs to the blockchain nodes; a step S 132  of the blockchain nodes extracting pieces of previous root hash information for registration included in pieces of previous transaction information on certificate retrieved from the blockchain by referring to said each of the previous transaction IDs; a step S 133  of the blockchain nodes transmitting the pieces of previous root hash information for registration to the authentication-managing server; a step S 134  of the authentication-managing server receiving the pieces of previous root hash information for registration, instructing its hashing engine to group pieces of previous node hash information for comparison, that have been stored in the certificate DB before said one of the anchoring conditions is met, into a plurality of sets whose size is determined by said one of the anchoring conditions, to thereby generate pieces of previous root hash information for comparison by hashing the pieces of previous node hash information for comparison set-wise; and a step S 135  of the hashing engine pairing each of the pieces of the previous root hash information for registration and each of the pieces of previous root hash information for comparison following their generation sequence, confirming that said each of the pieces of previous root hash information for registration is identical pair-wise to said each of the pieces of previous root hash information for comparison, to thereby complete a verification of whether the certificate stored in the authentication-managing server is forged or not.
