Abstract:
A method is provided for providing a notary service for a file, the method includes the steps in which: (a) when a notary service request for a specific file is obtained, a server generates, by using a hash function, or supports the generation of, a message digest of the specific file; and (b) if a predetermined condition is satisfied, the server registers, in a database, or supports the registration of, a representative hash value or a value obtained by processing the representative hash value, the representative hash value being generated by calculating at least one neighboring hash value that matches a specific hash value, wherein the specific hash value is a hash value of the result of encrypting the message digest with a private key of a first user, a private key of a second user and a private key of the server.

Claim (Index 19):
The method of  claim 18 , wherein\n (x1) the server calculates or supports another device to calculate (i) the second specific hash value and (ii) a hash value allocated to a sibling node of the specific leaf node where the second specific hash value is allocated, to thereby acquire a resultant value, and then allocates or supports another device to allocate a hash value of the resultant value to a parent node of the specific leaf node; (x2) the server, if the parent node is a root node of the Merkle tree, compares or supports another device to compare the hash value or its processed value allocated to the parent node, as the second representative hash value, with the first representative hash value or its processed value included in the OP message retrieved from the database; and (x3) the server, if the parent node is not the root node of the Merkle tree, repeats or supports another device to repeat the steps of (x1) to (x3) by using the hash value or its processed value allocated to the parent node as the second specific hash value.
