Desensitization tool for technological parameter curve graph

Abstract

The invention discloses a desensitization tool for a technological parameter curve graph, and relates to the technical field of information. The invention is composed of a picture input module, an image denoising module, an image binary matrix conversion module, a curve scanning module, a threshold setting module, a curve slicing module, a curve center scanner, a curve correction module and an image merging module. According to the invention, the problem that the original trend of the process parameter curve cannot be effectively reserved by adopting cutting, shielding, smearing and other desensitization methods in the past can be solved, and the service requirement of curve sensitive information desensitization can be met. The tool well adapts to desensitization of various industrial curve sample pictures through the threshold value setting module, the semi-automatic adjustment desensitization effect of the module can be achieved through threshold value setting parameters, and desensitization processing of continuous process curve pictures is achieved under the condition that a process parameter generation system is not changed.

Description

technical field [0001] The present invention relates to the field of information technology, especially the field of information security technology. Background technique [0002] With the vigorous advancement of industrial informatization, the informatization level of domestic industrial enterprises is getting higher and higher, and the application of process analysis software and testing software is becoming more and more extensive. Various types of software generate a large amount of process data, and a large part of the process data is presented by images and disseminated through image files. Especially in some "nuclear high-level" professional fields, most of the high-precision professional analytical instruments or software come from foreign companies such as Europe and the United States. These analysis devices or software do not disclose their internal data processing and storage processes, but only output picture files as analysis reports. [0003] As the core info...

Problems solved by technology

According to relevant regulations, when important data is exported, it must be desensitized! At present, there are some relatively mature desensitization methods for process data output by text output or database output, such as random data tampering, content alteration, data hiding, etc. These desensitization methods distort the original data, so that the receiver The effect of not being able to correctly recognize or normally restore the full content

The effect of applying these methods directly to the desensitization of the process image file curve is not ideal

First of all, the curves in the process image file present the statistical analysis results of the data, rather than the simple original data; second, in many cases, it is impossible to know the internal processing process of the process software or the measuring instrument, so the generation logic of the curve is unknown

Therefore, it is difficult to achieve desensitization of the process curve by adjusting the raw data! More importantly, the process curve usually represents the technical level of the product or system, and the enterprise hopes to show its overview to outsiders. The desensitization of the process curve is not a simple image distortion process, and the "one-step process" cannot be adopted. Painted on” approach, requiring desensitization with adjustable fidelity

[0004] Currently, there is a lack of desensitization methods or tools for process curves in process graphics files in the prior art
