Abstract:
The present invention relates to an accredited certificate issuance system based on a block chain and an accredited certificate issuance method based on block chain using the same, and an accredited certificate authentication system based on a block chain and an accredited certificate authentication method based on a block chain using the same, which disenable a leak of a personal key for accredited certification by autonomously generating, storing and managing the personal key for accredited certification by means of a random number generator mounted in a terminal in which it is impossible to install a function or an additional program for physically accessing and reading the inside of a system; enable a public key for accredited certification, which requires maintenance, to be stored and managed in a block chain of electronic wallets mounted in block chain retention servers via a peer-to-peer (P2P) network-based distribution database, not in a server operated by an accredited certificate authority (CA), and thus incur almost no costs for maintenance by, if hacking occurs, preventing occurrence of costs for establishing an accredited certificate issuance system having an advanced security system interworking therewith so as to maximally prevent hacking, and costs for operating and maintaining the established accredited certificate issuance system; and can perform an accredited certification process even if ActiveX is not established.

Claim (Index 35):
The method of  claim 30 , wherein, the transaction information for user verification includes input data ID 2  and output data OD 2 ,\n wherein the ID 2  has (i) a transaction ID of previous cryptocurrency payment, to be used for locating cryptocurrency to be spent which is part of cryptocurrency amount owned by a sender, using transaction information for the previous cryptocurrency payment, (ii) permission information on whether the sender is authorized to use the cryptocurrency, (iii) a public key for cryptocurrency payment required for validating the permission information, (iv) registration fee information on a fee amount required for registration of the user-verifying hash information for authentication needed for an issuance of the public certificate, and (v) cost deposit information on a fee amount to be used to revoke the public certificate, \n wherein the OD 2  has (i) OP_RETURN information which represents that the transaction information for user verification is not a monetary transaction related to the cryptocurrency payment but a meta-transaction for recording information, (ii) the user-verifying hash information for authentication OD 21 , (iii) revocation-confirming information OD 22  which contains transfer information including (iii-1) amount of a cost deposit corresponding to the cost deposit information and (iii-2) a reserve cryptocurrency address for transfer of the cost deposit to a designated cryptocurrency address, if the transaction information for user verification is stored in the blockchain of the blockchain nodes, and \n wherein the certificate-managing server has its transaction-processing engine and its DB part containing the keyword DB where the transaction ID for storing the public key for the public certificate and the transaction ID for user verification are stored; \n wherein the certificate-managing server, if a revoking signal which requests revocation of the public certificate is generated, instructs its transaction-processing engine to retrieve a transaction ID for user verification from the keyword DB and transmits the transaction ID for user verification to the blockchain nodes, \n wherein the blockchain nodes transmit to the certificate-managing server the transaction information for user verification retrieved from the blockchain by referring to the transaction ID for user verification, \n wherein the transaction-processing engine of the certificate-managing server, if the transaction information for user verification is received, generates transaction information for revocation and transmits the transaction information for revocation to the blockchain nodes, \n wherein the transaction information for revocation includes input data ID 3  and output data OD 3 , \n wherein the ID 3  has (i) transfer-guiding information which guides a transfer of the deposit cost loaded at the reserve cryptocurrency address by referring to the OD 2 , (ii) cryptocurrency multiple permission information including permission for a sender or user to use the deposit cost loaded at the reserve cryptocurrency address, and (iii) a public key for cryptocurrency payment required for determining validity of the multiple permission information for cryptocurrency, and \n wherein the OD 3  has (i) a cryptocurrency address of a receiver where the deposit cost loaded at the reserve cryptocurrency address is to be transmitted, and (ii) receiver identification information on the receiver, and \n wherein the blockchain nodes store the transaction information for revocation in the blockchain to thereby complete the revocation of the public certificate.
