摘要
二维码技术在防伪溯源领域的应用广泛,但二维码算法运用门槛低,易于伪造,且外观固化,用户难以直观区分条码的来源及用途。基于此,笔者提出一种新型防伪码算法,算法基于RS(20,8)信息编码、图像模板下信息嵌入及轮廓定位法下信息提取。新型防伪码算法将数据信息嵌入商标、签名等图像模板,使用专用解码器解码,能够优化防伪码外观、提高辨识度、有效提升防伪能力。
The two-dimensional code technology is widely used in the field of anti-counterfeiting traceability,but the twodimensional code algorithm has low application threshold,is easy to forge,and the appearance is solidified,so it is difficult for users to directly distinguish the source and purpose of the barcode.Based on this,a new anti-counterfeiting algorithm is proposed,which is based on RS(20,8)information coding,information embedding under image template and information extraction under contour positioning.The new anti-counterfeiting code algorithm embeds data information into image templates such as trademarks and signatures,and decodes them with special decoders,which can optimize the appearance of anti-counterfeiting code,improve the identification degree,and effectively improve the anti-counterfeiting ability.
