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.

The present invention relates to a secure information transmitting system and method for personal identity authentication, which, on the basis of a user public key, encrypt and transmit an authentication number transmitted from a server that provides a service to a user to a mobile communication terminal of the user, thereby preventing an unauthorized user who obtained the authentication number from being recognized even if an authentication number is externally exposed through hacking, wherein the number cannot be decrypted; and having a user public key required for encrypting an authentication number stored and managed in a block chain holding server that is tamper proof and is not a private server, and which, through means capable of providing same whenever needed, preemptively block the exposure of or tampering with the user public key through hacking which can be caused by managing the user public key in a private server. The secure information transmitting system for personal identity authentication comprises: a user terminal (100) for requesting a service desired by a user; a mobile communication terminal (200) which is possessed by the user and, when encrypted personal identity authentication information is received, decrypts and outputs the received encrypted personal identity authentication information; and a requested service providing server (300) which, when the service desired by the user is requested from the user terminal (100), encrypts information for personal identity authentication for requesting that the user is really the user, and transmits encrypted personal identity authentication information which is the encrypted information for personal identity authentication to the mobile communication terminal (200) possessed by the user who requested the service. The system and method are characterized in that after the user views the personal identity authentication information output to the mobile communication terminal (200), the user terminal (100) transmits the input personal identity authentication information to the requested service providing server (300), and after confirming the transmitted personal identity authentication information, the requested service providing server (300) implements controlling to provide the requested service desired by the user to the user terminal (100).

Provided are a certificate authentication system and an authentication method using the same. In the case of a public key for a certificate which requires maintenance, the present invention uses a means stored and managed in a block chain of electronic wallets embedded on block chain retention servers via a peer-to-peer network (P2P)-based distributed database, rather than a server operated by a certificate authority (CA), and thus the cost of constructing a certificate authentication system, with which a high level security system is linked in order to maximally block the occurrence of hacking, and the operation and maintenance costs for the constructed certificate authentication system are not generated, while it is also possible to surveil whether a user, who requests authentication, is fraudulent or not, and maintain a degree of PC security at a level desired by a user through a means which successfully guides an authentication process even if ActiveX is not installed. Thus, the present invention provides a block chain-based certificate authentication system which is not only strong in a risk environment such as hacking but also has a simple certificate authentication performance process and is compatible with various web browsers, and an authentication method using the same.
