摘要
可视信息分存技术能够将1幅二值图像分存为2幅或2幅以上表面看上去内容无关的图像。但在无需计算机参与,无需任何密码知识,也无需进行任何计算的情况下把几幅分存图像通过重叠合并就能够得到原始图。基于这个原理提出了一种可视信息分存的商标防伪技术,该技术解决了传统防伪技术难仿制和易推广的矛盾、易识别和防伪能力强的矛盾,实现了生产过程管理控制问题。
A binary image can be divided into two or more unrelated images using visual information sharing technology.But they can be overlapped to reconstruct the original one without a computer participating in,or any knowledge of cryptography any calculating.A new Brand anti-counterfeiting scheme was proposed base on visual information sharing.The traditional technologies have always been in a dilemma of easy imitation and hard promotion,also easy identification and high security.Meanwhile,the management of product process matters much.All the probems above can be well solved by this scheme.
