1.人体信息条码防伪技术自从上世纪末,美国IBM公司开始研究同心圆形(所谓牛眼)代码标识,用于商品以来,条形码技术得到不断完善。目前已有用于商品标识的肉眼可见的条形码。可见光照明下肉眼不可见,但是在紫外线、红外线的照射下能显示荧光条形码的用无色防伪油墨印制的条形码。采用数字符或混合编字符编入,具有高密度、高容量、译码可靠、纠错能力强与保密性好等特点,不仅可存入个人照片等自然情况及住址、电话等信息,还可存入供个人识别的
1. Human Information Bar Code Anti-counterfeiting Technology Since the end of the last century, the United States IBM company began to study concentric (so-called bull's eye) code logo, used for goods, bar code technology has been continuously improved. Currently there are visible bar codes for product identification. Visible light under the naked eye is not visible, but in the ultraviolet, infrared light can display fluorescent bar code printed with colorless security ink bar code. Adopting characters or mixed characters, it features high density, high capacity, reliable decoding, strong error correction ability and good confidentiality. It not only can store personal information such as natural conditions and address, telephone and other information, but also Deposited for personal identification
