    摘要： A method of registering a point distributor and an exchange rate for a united point service is provided. The method includes steps of: a system managing server (a) verifying a registration transaction TrxA or a confirmation transaction TrxB if (i) a condition that the TrxA having a public key of a point managing server, and a first XEA, an exchange rate of a point A of a point distributor to the united point, is acquired from a point distributing server, or (ii) a condition that the TrxB having a public key of the point distributing server and a second XEA is acquired from the point managing server, is satisfied; and (b) if the TrxA or the TrxB is valid, (i) recording it on a blockchain database, (ii) initializing a balance database by updating a balance of the point distributor, and (iii) acquiring a transaction ID of the TrxA, the TrxB.

    摘要： A method for a payment for an Internet of Things (IoT) device is provided. The method includes steps of: a payment supporting server (a) on condition that the payment supporting server has registered certificates of the IoT device, a service providing device, and a digital wallet, and manages corresponding blockchain transaction IDs and link information, if a billing transaction is acquired, validating the billing transaction including identification information on the service providing device and the IoT device, a billing detail, and a signature value; (b) acquiring identification information on the digital wallet corresponding to the billing transaction from the blockchain database; and (c) (i) paying the billing detail using the digital wallet, (ii) registering a payment result including a payment detail in the blockchain database and managing its blockchain transaction ID, and (iii) transmitting the payment result to the service providing device, the IoT device, and the digital wallet.

    摘要： The present disclosure provides a method for superseding a log-in through PKI-based authentication with respect to a log-in request of a user by using a blockchain database. According to the method, once authentication request information requesting superseding of a log-in through an authentication app is obtained from a service provision app executed on a user terminal, a service provision server transfers authentication request response information to the service provision app and, after an authentication redirection request thereof is transferred to the authentication app and then server challenge request information is obtained, server challenge request response information is transferred to the authentication app, an authentication result message including information on whether certificates of the server and the app are valid is obtained from an authentication server, a predetermined access token is transferred to the service provision app, and thereby the log-in is handled such that a service can be used.

    摘要： A method, user device, and service providing server are provided for information management using a specific tree based on a blockchain. Aspects of the described approach include registering in an open ledger of the blockchain private data that belongs to a set of private data that identifies a particular subject. Furthermore, pseudo-public data including prefix values that correspond to specific private data are generated, registered as sub-data corresponding to a sub-structure of a specific leaf node to which the specific private data is allocated. Also, a pseudo-public function is created based on the pseudo-public data allocated to the specific leaf node.

    摘要： The present invention, when at least one from among chat participants requests recording of data generated by the chat participants in an environment in which a messenger bot participates in a chat, registers at least a portion of the generated data as recorded data in a database, provides a transaction ID indicating location in the database of the data registered therein to at least one participant from among the chat participants, determines, in response to a recorded data-related verification request, whether input data included in the verification request corresponds to the recorded data, and, if the input data corresponds to the recorded data, then concludes the recorded data-related verification to have been successful.

    摘要： 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.
