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 26):
A server for verifying a file recorded by using a notary service, comprising:\n a communication part for acquiring or supporting another device to acquire a verification request for the file; and a processor for, on condition that the server has acquired a notary service request for the file, and then has registered a first representative hash value or its processed value in a database, wherein the first representative hash value is generated by using a first specific hash value and its corresponding at least one neighboring hash value under one of anchoring conditions, and wherein the first specific hash value is a hash value of a result acquired by encoding a specific message digest of the file with a private key of a first user, a private key of a second user, and a private key of the server, if the verification request is acquired, and if a second representative hash value or its processed value, generated by using input data included in the verification request, corresponds to the first representative hash value or its processed value registered in the database, determining or supporting another device to determine that a verification of the file is completed.
