所述的防伪标识其所用随机掺杂材料的制作过程,是在透明体内部嵌入第二相随机分布的不透明物质构成防伪标识材料,通过光照其体内嵌入的不透明物质材料的方式产生点阵图形。 The security identification manufacturing process they use random dopant material, an opaque material is embedded in a second phase the random distribution in the interior of the transparent member constituting the anti-counterfeit marking materials, by way of light opaque material embedded within its material produces a dot pattern.

所述的公开密钥加密方法,是利用生产者的以数字形式表示的加密密钥,和由随机掺杂标识材料产生点阵图形的数字化处理后得到的对应数字,通过公开密钥加密算法的处理产生以数字或条码形式表示的密码。 The public key encryption method, the encryption key using the producer expressed in digital form, and generates the corresponding digital processing after digital dot pattern identified by a random dopant material obtained by the public key encryption algorithm treatment yields expressed in digital code or bar code form.

所述的公开密钥解密算法及比较验证方法,验证者利用公开的以数字或条码形式表示的解密密钥,通过公开密钥解密算法,对以数字或条码形式表示的密码解密后得到的数字和由随机掺杂标识材料再次通过光照产生的图形经过数字化处理后的数字比较来验证标识的唯一性。 The public key decryption algorithm and Comparative authentication method, disclosed by using a decryption key or bar code expressed in digital form, by a public key decryption algorithm to obtain the password or expressed in digital form decrypted digital barcode and random pattern of light generated by the dopant material identified again digitally processing the digital comparator to verify the unique identification.

所述的防伪密钥传送方式,是利用计算机网络下载、购买书刊或计算机软件的方式传送随机掺杂材料公钥密码防伪标识的以数字或条码形式表示的解密用密钥。 The security key transport mode, using a computer network download, purchasing books or computer software transmission of the random doping material identified security of public key cryptography decryption keys represented in digital form or barcode.

上述“第二相”是材料专业的术语,意思是一种材料中包含有另1种不同性质的材料。 The above "second phase" is a material professional terms, means a material comprising the other type of materials of different nature.

上述“公开密钥(简称公钥)加(解)密算法”是密码专业的术语,用它对数字加解密过程是:加密时,将一组数字(设为a)和加密密钥(以数字形式表示)混合产生密码(以数字形式表示)。 The above "public key (the public key) (de) encryption algorithm" is the password specialized terminology, with its digital decryption process: encryption, a set of numbers (referred to a) and encryption key (in represented in digital form) to produce a mixed code (represented in digital form). 解密时,使用解密密钥(以数字形式表示)和密码混合还原数字(已经设为a)。 Decrypting, using the decryption key (expressed in a digital form) and reducing mixed password number (already set a). 其特点是:加密密钥和解密密钥是不相同的。 It characterized by: an encryption and decryption keys are different.

根据随机分布第二相防伪标识材料的制作过程可知,随机分布第二相防伪标识材料实际上是不可复制的。 The production process of the second phase the random distribution of the apparent anti-counterfeit marking material, a second phase the random distribution of the material is actually anti-counterfeit labels can not be copied. 因此,防伪标识材料具有唯一性特征。 Thus, a material having a unique security identification features. 根据公钥密码算法的原理可知制造者随机选择的私有密钥数字是实际无法破译和伪造的。 According to the principle of public key cryptography algorithm known manufacturer randomly selected private key number is the actual indecipherable and forgery. 标识材料唯一性和制造者私有密钥数字保密性的结合就会产生不可复制的制造者独有的防伪标识。 The only binding maker private key and a digital secrecy marking material manufacturer will have a unique anti-counterfeit labels can not be copied.

具体实施方式 Detailed ways

本发明是这样实现的:一、制造者取第二相不透明物质材料随机分散到3维透明体中,制做出内部嵌入随机分布第二相的3维防伪标识材料。 The present invention is implemented as follows: First, the manufacturer taking a random second phase material dispersed in an opaque substance transparent three-dimensional body, a three-dimensional system to make anti-counterfeit marking material embedded within the random distribution of the second phase.

三、制造者将验证用数字输入到计算机中。 Third, the manufacturer verifies the digital input to the computer. 再输入制造者随机选择的私有密钥(以数字形式表示,数字越长越难被破译),通过公开密钥加密算法产生密码(以数字或条码形式表示)。 Enter the manufacturer randomly selected private key (expressed in digital form, digital longer difficult to be deciphered), the password is generated (expressed in a digital form or barcode) by public key encryption algorithm.

四、制造者最后将密码打印成数字或条码和随机分布第二相的防伪标识材料并排粘贴或嵌入到物品上形成防伪标识。 Fourth, and finally the manufacturer password number or barcode printed security marking material, and a random distribution of the second phase of the paste or embedded side by side to form a security article identification.

五、检验人用制造者同样的方法,通过对已经制作出的随机掺杂材料光照、图像采集和数字化处理产生相同的验证用数字,将验证用的数字输入到计算机中。 Five test persons the same way the manufacturer, to produce the same digital verification has been fabricated by a random dopant material illumination, image acquisition and digital processing, the digital input to the verification computer.

六、检验人将密码输入到计算机中,再输入制造者向社会公开的解密密钥(以数字或条码形式表示,数字越长安全性越好),通过公开密钥解密算法在计算机中产生鉴别用数字。 Six people will test the password entered into the computer, and then enter the decryption key maker open to the public (expressed as a number or bar code form, the longer the better digital security), generated by the computer to identify the public key encryption algorithm digital.

七、计算机自动对比验证用数字和鉴别用数字,如果两者相同,计算机显示防伪标识为真实,如果两者不同显示防伪标识为假。 Seven, the computer automatically compare verification and identification numbers with the number, and if identical, the computer displays anti-counterfeit labels to be true, if the two different display false security identification.

本方法与现有方法相比有如下优点:一、本方法是一种用于标识的实际上无法复制的防伪方法。 Compared with this conventional method has the following advantages: First, the method is a method for identifying security practically can not be copied.

二、本方法中的防伪标识材料的制造方法公开;加密解密算法公开;防伪标识图像采集及数字化处理方法公开;解密密钥和加密后的密码(以数字或条码形式表示)公开,只有加密密钥(以数字形式表示)由制造者随机选取并保密。 Second, the method of manufacturing anti-counterfeit marking material according to the method disclosed; encryption and decryption algorithms disclosed; anti-counterfeit identification image capture and digitize the method disclosed; password decryption key and the encrypted (represented in digital or bar code form) is disclosed, only the encryption key (expressed in digital form) randomly selected by the manufacturer and confidentiality.

三、本方法中的加密解密处理过程可以使用现有的密钥自动生成、密钥分配、密钥自动调用等密码处理技术。 Third, the encryption and decryption process according to the present method may be automatically generated using existing key, key distribution, key cipher processing techniques like automatic calling.
