The present invention discloses a forgery/alteration prevention apparatus. A forgery/alteration prevention apparatus according to an aspect of the present invention comprises: a forgery/alteration prevention module which encrypts at least one piece of data, obtained by dividing target data, whose forgery/alteration are to be prevented, into predetermined size units, using a predetermined algorithm, generates a password key corresponding to the at least one piece of data, and stores the password key; and a forgery/alteration determination module which generates a determination key corresponding to the at least one piece of data when the at least one piece of data is encrypted by the algorithm, and determines whether the target data has been forged/altered using the determination key corresponding to the at least one piece of data and the password key corresponding to the at least one piece of data. The algorithm is an encryption method in which the content and sequence of the at least one piece of data are taken into consideration. |
