Abstract

A digital forensic image verification system according to an embodiment of the present disclosure includes an imaging device having a imaging unit configured to produce an image, a first hash value generator configured to generate a first hash value for the image, and a transmitting unit configured to transmit the image and the first hash value; and an image storage device having a receiving unit configured to receive the image and the first hash value from the imaging device, a second hash value generator configured to generate a second hash value for the image, and a controller configured to compare the first hash value and the second hash value with each other.

Description

TECHNICAL FIELD

[0001] The present disclosure relates to a digital forensic image verification system, and more particularly, to a digital forensic image verification system in which an imaging device which captures an image generates a first hash value and transmits it to an image storage device, and the image storage device generates a second hash value and verifies whether the image has been forged or altered by comparing the first hash value and the second hash value with each other.BACKGROUND ART

[0002] Digital forensics is a branch of security service which is used to verify a fact occurring, based on digital materials stored in a digital medium such as a computer, and is related to collecting and analyzing scientific evidence used in a criminal investigation.

[0003] As described above, in digital forensics, evidence cannot be used when it is not objectively proved that the evidence has not been forged or altered in collecting and analyzing the evidence. Thus, techniques for verifyi...
