Abstract:
Provided is a method according to one embodiment of the present invention comprising the steps of: (a) a server generating, by means of a hash function, a message digest (MD) of a particular file when a request for authenticating same is obtained; (b) when an MD encoded with a private key of a particular user is obtained, and if (A) information for the MD, which was encoded with the private key of the particular user, decoded with a public key of the particular user matches (B) the MD generated in step (a), then the server registering, in a database, a hash value of the MD encoded with the private key of the particular user and a private key of the server; and (c) the server obtaining a transaction ID.

Claim (Index 31):
A server for verifying a file, comprising:\n a communication part for acquiring a verification request for a second file; and a processor for, (I) on condition that the server has determined a user as related to a first file, as a reference file, in response to an authentication request for the first file and, as a result, that the server has stored a first hash value of a first message digest, generated by encoding a message digest of the first file with a private key of the user and a private key of the server, in a database, and that the server has been managing its corresponding transaction ID, if the verification request for the second file is acquired, acquiring or supporting another device to acquire the transaction ID corresponding to at least one of a public key of the user and an original message digest of the second file generated by using a hash function; (II) acquiring or supporting another device to acquire an OP message, including the first hash value of the first message digest, from the database by referring to the transaction ID; and (III) determining or supporting another device to determine the second file as verified, if the first hash value in the OP message corresponds to a second hash value of a second message digest generated by encoding the original message digest with the private key of the server and the private key of the user.
