Apparatus for Preventing Data Falsification and Verificating Data Falsification

摘要

The present invention discloses an apparatus and a method for preventing forgery and falsification. According to an aspect of the present invention, there is provided an apparatus and method for preventing forgery and falsification, comprising: encrypting at least one piece of data obtained by dividing target data to be forbidden to be falsified into units of predetermined sizes by a predetermined algorithm; A forgery-and-falsification prevention module for generating and storing each; And generating a discrimination key corresponding to each day data by encrypting each day data by the algorithm, and using the discrimination key corresponding to each day data and the cryptographic key corresponding to each day data, And a forgery and falsification determining module for determining whether or not the data is forged or falsified, wherein the algorithm is an encryption method that considers the contents and order of the at least one data.
