摘要:

数字图像的安全问题是多媒体信息安全的重点,本文对网络图片的防盗保护问题进行研究,主要思路是防止用户直接轻松地通过截取屏幕来获得图片。为此,本文首先借助人眼的视觉暂留特性,提出类似动画合成帧的保护策略,使得每一帧总有部分像素被隐藏起来或被模糊处理。然后,从多个角度设计若干个数值实验并作对比分析。实验结果表明,本文提出的方案既不会对图片的实际浏览效果带来明显的影响,又能达到在任何时刻无法完整截取图片的目的。本文的研究成果能有效遏制网络图片的非法盗用和二次分发,维护原创者的合法权益。

The security problem of digital image is the key point of multimedia information security. This paper focuses its research on the security protection of network pictures, and the main idea is to prevent the network users through screen shot to get pictures easily and directly. Therefore, this paper firstly utilizes the persistence of vision characteristic of human eyes and proposes a protection strategy similar to animation frames, so that some pixels of each frame can be hidden or fuzzy processed. Secondly, this paper designs a number of numerical experiments from multiple angles and then conducts comparative analysis. The experimental results showed that the scheme we put forward would neither cause distinct influences when network users skimmed through the network pictures, nor could they get the pictures completely through screen shot at any time. The research results of this paper can prevent the illegal utilization of network pictures and the second distribution effectively, so as to preserve the legitimate rights of the original.
