Abstract

The invention discloses a novel bar code screenshot steganography traceability combination algorithm, and belongs to the technical field of information identification. The method comprises the following specific steps: (1) performing starting; (2) analyzing image compatibility; (3) generating fingerprints; (4) performing image segmentation and steganography; (5) performing merging and adjusting; (6) performing ending. According to the invention, through Fourier steganography, LSB steganography and color overlay steganography technologies, on the premise that the bar code is not modified and image changes which can be distinguished by human eyes are not generated, specified character information is written into the picture containing the bar code, and corresponding information can be traced back according to the screenshot after the screenshot is carried out; the method has the effects of high robustness and high compression resistance, and is favorably applied to a platform with a confidentiality requirement, so that information leakage is effectively prevented and blocked.

Description

technical field

[0001] The invention relates to the technical field of information identification, in particular to a novel combination algorithm for steganography traceability of barcode screenshots. Background technique

[0002] After retrieval, Chinese Patent No. CN108898537A discloses a digital image steganography method. Although this inventive method can minimize the distortion caused to the carrier image after embedding secret information, it cannot reversely trace the corresponding information based on the screenshot after being captured. ; Steganography is the use of redundancy in multimedia such as text, sound, image, and video and human sensory redundancy to hide information in multimedia and transmit it through a public network to achieve covert communication; steganography not only hides The content of the communication hides the fact of the communication at the same time; due to the large number of images on the network, the redundancy of image data, and the la...
