Abstract:
Provided is a method according to the present invention comprising the steps of: (a) generating a message digest of a particular file when a request for authenticating same is obtained; (b) when a message digest encoded with a private key of a first user and a message digest encoded with a private key of a second user are obtained, and if the (i) (A) information for the message digest, which was encoded with the private key of the first user, decoded with a public key of the first user, (ii) (B) information for the message digest, which was encoded with the private key of the second user, decoded with a public key of the second user, and (C) the message digest generated in step (a) match, then registering, in a database, a hash value of the message digest encoded using the private key of the first user, private key of the second user and a private key of a server; and (c) obtaining a transaction ID reflecting location information of the registered hash value in the database.

Claim (Index 8):
A server for authenticating a file, comprising:\n a communication part for acquiring or supporting another device to acquire an authentication request for the file; and a processor for, (I) if the authentication request for the file is acquired, generating or supporting another device to generate a specific message digest of the file using a hash function, (II) if a first message digest generated by encoding the specific message digest with a private key of a first user, and a second message digest generated by encoding the specific message digest with a private key of a second user are acquired, and if each piece of (i) first information acquired by decoding the first message digest with a public key of the first user and (ii) second information acquired by decoding the second message digest with a public key of the second user, corresponds to the specific message digest generated in the process of (I), registering or supporting another device to register a hash value of a third message digest, generated by encoding the specific message digest with the private key of the first user, the private key of the second user, and a private key of the server, in a database, and (III) acquiring or supporting another device to acquire a transaction ID indicating a location of the hash value registered in the database; and wherein, at the process of (II), the processor, if the said each piece of the first information and the second information corresponds to the specific message digest, registers or supports another device to register an encoded value, which is acquired by encoding a sum value with the private key of the server, in the database, and wherein the sum value is a sum of the first message digest and the second message digest.
