A file encryption system according to the embodiment of the present invention may include a first digital device (10) comprising a storage part (12) for storing a digital file, an input part (14) for inputting a password, a control part (16) which generates the checksum of the digital file stored in the storage part (12) and encrypts the checksum by using the password inputted by the input part (14), and an interface part (18) for transmitting and receiving the encrypted digital file to and from an external device. So, whether a replicated digital file is corrected/modified can be confirmed. |
