Embodiment 1

[0015] As shown in FIG. 1 , the digital image encryption processing system 100 of Embodiment 1 of the present invention includes at least: (a) image error-proof encoding module 110; (b) identification data setting module 120; (c) identification data storage module 130 (d) identification data error-proof encoding module 140; and (e) identification data embedding module 150;

Embodiment 2

[0017] As shown in Figure 2, the digital image encryption processing system 100' according to Embodiment 2 of the present invention further includes a digital signature encoding module 210 in addition to the above-mentioned modules, and the identification data setting module 120 further includes: sales data setting Setting unit 123, buyer data setting unit 124 and photographer data setting unit 125.

Embodiment 3

[0019] As shown in FIG. 3 , on the basis of Embodiment 2, the digital image encryption processing system 100 ″ of Embodiment 3 of the present invention further includes a geographic location data embedding module 310 .

[0020] In practical applications, the digital image encryption processing system 100 of Embodiment 1 of the present invention is loaded into a basic digital camera with the lowest encryption level; the digital image encryption processing system 100' of Embodiment 2 is loaded into a digital camera with a medium encryption level; The digital image encryption processing system 100" of Embodiment 3 is loaded into the digital camera with the highest encryption level.

[0021] The image error-proof encoding module 110 can perform predetermined error-proof encoding procedures on the binary code of the original digital image 20, such as a 16-bit cyclic right shift total value check encoding program, an 8-bit sum total value check encoding program, a 32-bit difference ...

Abstract

A digital image encryption processing system at least includes: an image error-proof encoding module, an identification data setting module, an identification data storage module, an identification data error-proof encoding module, and an identification data embedding module; the digital image encryption processing system of the present invention can be loaded into Digital image capture device, which performs special encryption processing on the digital images captured by the digital image capture device, so that image users can identify whether a certain digital image is indeed captured by the digital camera and has not been tampered with, making the digital image When a digital image capture device is used as a legal evidence collection tool, it can be trusted by the public.

Description

technical field [0001] The present invention relates to a digital image technology, in particular to a digital image encryption processing system, which can be loaded into a digital image capturing device, such as a digital still camera (Digital Still Camera, DSC), to perform digital image processing on the digital image captured by the digital camera. A special encryption process allows image users to verify whether a certain digital image is indeed taken by the digital camera and has not been tampered with. Background technique [0002] A digital camera (Digital Still Camera, DSC) is an image information capture platform, which can capture optical images of various objects and landscapes, and convert the captured optical images into digital images. Compared with traditional film cameras, because digital images are more convenient to use and store than negatives, digital cameras tend to gradually replace traditional film cameras. [0003] However, because the digital image...
