[0051] figure 1 is a block diagram of a digital forensic image verification system according to an embodiment of the present disclosure. The digital forensic image verification system includes a photographing device 100 and an image storage device 200 .

[0052] More specifically, as figure 2 As shown in , the photographing device 100 includes a photographing unit 110 , a first hash value generator 120 , a multiplexing unit 130 and a sending unit 140 .

[0053] The photographing unit 110 of the photographing device 100 generates sound and images.

[0054] The first hash value generator 120 of the photographing device 100 generates first hash values ​​for sound and images at intervals of a certain time.

[0055] For example, if image 3 As shown in , when it is assumed that sound and image are generated from 12:01:00 to 12:01:03 and the specific time is 1 second, the first hash value generator 120 may be from 12:01:00 to 12:01: 01 produces a 1-1 hash, 1-2 hashes from 12:0...

[0093] will refer to Figure 6 Another embodiment of the present disclosure is described. The digital forensic image verification system according to this embodiment includes a photographing device 300 and an image storage device 400 .

[0094] The photographing device 300 includes a photographing unit 310 , a first hash value generator 320 and a sending unit 340 .

[0095] The photographing unit 310 generates images. However, the embodiment is not limited thereto, and the photographing unit 310 may generate sound and images.

[0096] The first hash value generator 320 generates a first hash value for a portion of an image generated by the photographing unit 310 . Accordingly, the load applied to the first hash value generator 320 may be more reduced than when the first hash value is generated for all images generated by the photographing unit 310 .

[0097] As a method of generating the first hash value for a part of the image generated by the photographing unit 310 by th...

[0107] The digital forensic image verification system according to the present embodiment differs from the digital forensic image verification system according to the second embodiment in the first hash value generator and the second hash value generator. will refer to Figure 6 This embodiment is described. In the following description about the present embodiment, the first hash value generator and the second hash value generator are assigned the same reference numerals as those according to the second embodiment.

[0108] The digital forensic image verification system according to this embodiment includes a photographing device 300 and an image storage device 400 .

[0109] The photographing device 300 includes a photographing unit 310 , a first hash value generator 320 and a sending unit 340 . The image storage device includes a receiving unit, a second hash value generator and a controller.

[0110] The photographing unit 310 generates images. However, the embodiment ...

Abstract

A digital forensic image verification system, according to one embodiment of the present invention, is provided with: a photographing device comprising a photographing unit for generating an image, afirst hash value generation unit for generating a first hash value for the image, and a transmission unit for transmitting the image and the first hash value; and an image saving device comprising a reception unit for receiving the image and the first hash value from the photographing device, a second hash value generation unit for generating a second hash value for the image, and a control unit for comparing 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, wherein a photographing device that captures an image generates a first hash value and sends it to an image storage device; the image storage device A second hash value is generated, and it is verified whether the image has been forged or altered by comparing the first hash value and the second hash value with each other. Background technique [0002] Digital forensics is the branch of security services used to verify factual occurrences based on digital material stored in digital media such as computers, and involves the collection and analysis of scientific evidence for use in criminal investigations. [0003] As mentioned above, in digital forensics, evidence cannot be used when it has not been objectively proven that the evidence has not been falsified or altered in the collection and analysis of th...
