Description

组合二维码防伪系统和方法、组合二维码、识读装置 技术领域
本发明涉及组合二维码防伪系统和方法、组合二维码、识读装置，尤其涉及利用二维码对物品的真伪进行验证。
背景技术
二维码由于制作容易、成本低被广泛用于物品的真伪验证。将编有网址的二维码粘贴、印刷在物品或包装表面，用户用手机等识读设备扫描二维码，即可自动链接到验证网站，在网站的页面上输入验证数字即可与数据库中的数据进行对比，对物品的真伪进行验证。由于二维码的伪造非常容易，为提高防伪性能，通常还进行暗码处理，如在验证数字上设置覆盖层，需要刮取覆盖层才能看到验证数字。
但是利用暗码的防伪，需要用户的配合，如果用户预先不知道有覆盖层，对伪造的二维码就没有识别能力，无法区分真假二维码。即，现有的验证方法有以下缺点：1)使用不便，用户需要手动输入数字，容易出错；2)对系统的造假，没有防伪能力，即二维码、验证数字、网址一起造假，用户不易识破。
本申请的发明人在授权公告号CN101615258B(申请号：200810115748.0)公开了一种变码技术，该二维码被至少部分覆盖，使得覆盖层被至少部分去除前二维码不能被识读解码，达到防伪目的。
这种方法虽然提高了用户方便性问题，但由于绝大部分二维码都是采用公开算法，容易被系统伪造，即二维码、网址一同的造假，用户不易识破，防伪漏洞依然存在。
公开文献1(公开号CN102270294的专利公开文件)中公开了利用条形码的防伪技术。二维码和条形码分别粘贴在物品或包装的不同位置。二维码中的一部分信息做加密处理形成隐藏信息，使明文信息不完 整，加密用的密钥编入条形码中。用条形码解码工具对条形码中的密钥解后，才能解码隐藏信息。用户根据隐藏信息与明文信息是否构成一个完整的信息，来判断真伪。但从内容上判别两者的关联性依赖于用户的经验，容易出现判断错误，防伪效果因人而异。

具体实施方式
以下通过具体实施方式对本发明的组合二维码防伪系统、识读装置及组合二维码进行说明。
首先对组合二维码进行说明。
图1、2是本发明的组合二维码的构成说明图。图1是未设覆盖层的说明图；图2是设置有覆盖层的说明图。
如图1所示，组合二维码由二维码30和点阵100两部分构成，点阵100的设置区域40位于二维码30的右下方(即没有定位图形的位置)由二维码30的3个定位图形31定位在两侧边位置，与二维码30在图形上保持关联。
在本实施方式中，矩形的设置区域40被划分成4*16个模块用于编码，深色的点阵100与白色部分构成二进制信息的两种状态，一个深色圆点和与之相应大小的白色部分分别代表一位，点阵100中相邻的圆点之间保持一定的间隙，避免互相连在一起，以提高图像处理效率和视觉效果。由于点阵100的形状与二维码30中的矩形模块形状不同，点阵 100还起到组合二维码的标识作用。
点阵100的设置区域40的大小参照二维码30的纠错等级(纠错容量)设定，以使点阵100引起的误码率与二维码本身的误码率之和小于二维码的纠错率，保证二维码30的解码不受影响。由于二维码30的误码率不仅受点阵区域40面积大小的影响，编入点阵100中的信息也会影响二维码的误码率，为避免编入信息的变化，造成二维码30无法解码的情况出现，在根据纠错等级设定设置区域40的大小时，留有完全余量，具体可通过实验确定。如根据模块的分布选择一种极端情况，确定设置区域的上限值，在上限值以内确定具体设置区域的大小。具体也可参照本发明的发明人在授权公告号CN101615258B(申请号：200810115748.0)中公开的技术确定，在此不再赘述。
设置区域40的长宽比以及形状可以任意设置，点阵100也可以一部分位于二维码30的图像区域外，以提高点阵100的信息容量。
由于设置区域40的大小与纠错等级关联，在编制组合二维码时能够根据二维码30的纠错等级自动调整设置区域40的大小；在识读时，能够利用二维码30中的版本、纠错等级等参数，确定点阵100的读出区域，方便信息处理。
点阵100也可不采用黑圆点的形状，用文字或其他图案的形状代替，只要能作为一个单独的模块被识别即可。点阵100中的圆点也可以采用与二维码30中的模块相同大小和形状。
二维码30为采用国家标准(GB/T18284-2000)的QR码，任何标准的编码设备和识读设备均能制作和解码。
点阵100的表面如图2所示，形成有覆盖层200，覆盖层200可以是刮刮墨、不干胶贴、激光贴膜等。
与二维码30相同，点阵100中编入的信息也具有纠错功能，点阵100至少被覆盖层200部分覆盖，使得覆盖后点阵100不能被识读，即覆盖引起的点阵100的误码率大于纠错率，该覆盖层200只限于点阵100，不影响二维码30的识读。当覆盖层200被至少部分移除后，该点阵100可以被识读，即只要移除部分覆盖层200，使点阵100的误码率 小于其纠错率，点阵100即可识读。
二维码300中编入数据信息包括：字符、数字、文字、网址、图形、图像、动画等，或它们的组合；点阵100中编入密码信息，包括：字符、数字等。在实施方式中，编入以下的信息。第一行的数字是物品的物流码，产品序号或产品批次。第二行是下载验证软件的指示。
编入二维码30的信息：
·234734631212
·下载“雅培奶粉”APP验证。
在组合二维码1的点阵100中编入的密码信息如下，密码信息采用保密算法。
·963215。
二维码30中的数字(物流码等)与点阵100的密码信息组成验证用信息。
因此，覆盖层200未移除时，智能手机等识读终端只能识读二维码30中的信息，用户可以验证物流码、产品序号、产品批次等。识读终端在解码信息的引导下，自动或通过手动点击链接到对应的网站，下载“雅培奶粉”验证软件。
在至少部分移除覆盖层200后，识读终端中下载的“雅培奶粉”验证软件对点阵100的密码信息进行解码，并将二维码30中的数字234734631212(物流码)与点阵100中的数字963215(密码信息)组合成验证用信息，通过数据库或本地验证，以确定二维码的真实性，对物品的真伪进行验证。
变形例
图3是图1的变形例，如图3所示，点阵100的设置区域40设置成椭圆形，与图2相同，点阵100中也设置有覆盖层(未图示)，其他结构不变。
图4是图1的变形例，如图4所示，点阵100的设置区域有两个位于不同位置，不同形状的设置区域40a和40b组成，与图2相同，点阵100中也设置有覆盖层(未图示)，覆盖层既可以设置其中的一个设置 区域，也可以两个设置区域都设置，只要保证覆盖层被至少部分移除前，无法解码即可。其他结构不变。
实施方式2
以下对另一种组合二维码的结构进行说明。
图5是另一种组合二维码的构成说明图，与图1不同的是点阵100的设置区域50由50a、50b、50c、50d组成，各设置区域分别位于二维码30图形的各侧边外侧，点阵100呈多边单排的结构。与图1的结构相同，设置区域50a、50b、50c、50d由二维码30的定位图形31定位，与侧边保持一定间隔。设置区域50的大小与二维码30的大小保持关联。由于点阵100不会影响二维码30的解码，设置区域50的范围不用与二维码30的纠错等级关联，可以设置更大的信息容量。与图2相同，各个点阵或部分点阵中也设置有覆盖层(未图示)，保证覆盖层被至少部分移除前，无法解码。
图6是图5的变形例，图6中，点阵100的设置区域由图5中的四组改变成左右各一组，各个设置区域中设置两排点阵100，点阵的总信息容量与图4相同。包括设置覆盖层(未图示)，其他部分与图5中的结构相同。
图7是图5的变形例，图7中，点阵100的设置区域由图5中的四组改变成右边一组，设置区域中设置四排点阵100，点阵的总信息容量与图4相同。包括设置覆盖层(未图示)，其他部分与图5中的结构相同。
图8是图5的变形例，图8中，在点阵100的外侧设置三个点阵定位图形51，分别位于二维码30的三个定位图形31的外侧。通过三个点阵定位图形51确定点阵100的位置和范围。点阵定位图形51具有特定的形状，供图象输入设备或光电扫描设备读取。同时，点阵定位图形51还起到组合二维码范围的标识作用，方便确定扫描范围。图8中省略了覆盖层，与图5相同，点阵100的表面也设置有覆盖层。
图3至8仅用于说明组合二维码的变形结构，内容上，只要将图1中编入二维码和点阵的信息同样编入各图的二维码和点阵中，并在点阵 100的表面设置使误码率大于纠错率的覆盖层即可，与图1具有同样的效果。
以下对使用组合二维码进行物品防伪的组合二维码的防伪系统进行说明。
图9为组合二维码的防伪系统的结构框图。
如图所示，具有组合二维码300、识读终端400、网络500、数据库600、服务器700。
组合二维码300为图2所示的组合二维码，组合二维码300中编入的信息与之前的相同，即，二维码30中编入的信息如下：
·234734631212
·下载“雅培奶粉”APP验证。
点阵100中编入的密码信息如下，
·963215。
识读终端400由具有二维码识读功能的智能手机构成，包括组合二维码读取模块401、二维码解码模块402、联网模块405、显示模块406。通过安装“雅培奶粉”APP验证软件还具有点阵解码模块403、验证数据生成模块404。
组合二维码读取模块401用于读取粘贴、印刷或打印在待验证物品或外包装上的组合二维码300。
二维码解码模块402用于对组合二维码300中的二维码30解码；点阵解码模块403用于对二维码300中的点阵100解码；验证数据生成模块404将二维码30中与验证相关的信息与点阵100中的密码信息结合成验证用信息，用于二维码(物品)真伪的验证；联网模块405用于与服务器700和数据库600连接；显示模块406用于显示二维码30的解码信息和验证结果。
网络500用于解码终端400与数据库600和服务器700连接。
数据库600用于验证物品的真伪，具有验证模块601、计数模块602。
服务器700提供验证用APP(验证软件)下载。
以下对组合二维码防伪方法进行说明。图10为组合二维码防伪方 法的流程图。
组合二维码粘贴、印刷或打印在物品的表面或外包装上，用安装有识读终端400的手机拍摄组合二维码300。如图10所示，
步骤1，组合二维码读取模块401读取粘贴、印刷或打印在待验证物品或外包装上的组合二维码300。
步骤2，二维码解码模块402对组合二维码300中的二维码30解码，得到如下信息，此时，点阵100被覆盖层覆盖，无法读取和解码。
·234734631212
·下载“雅培奶粉”APP验证。
步骤3，显示模块406显示该信息。
步骤4，下载并安装“雅培奶粉”APP验证软件，在识读终端400中生成点阵解码模块403、验证数据生成模块404。
步骤5，移除至少部分覆盖层，使点阵100能够解码，并再次拍摄
组合二维码300。
步骤6，点阵解码模块403对二维码300中的对点阵100解码，得到密码信息963215。
步骤7，验证数据生成模块404将二维码中的数字234734631212与点阵中的963215结合起来，生成验证用信息(数字)234734631212963215。该验证用数字由网络500发送数据库600。
步骤8，数据库600中的验证模块601将验证用数字与存储在数据库中的字符串做对比，进行验证，同时、计数模块602对验证的次数进行计数。验证的结果和验证次数通过网络500再发送到识读终端400。
步骤9，识读终端400中的显示模块406显示验证的结果和验证次数。即，与数据库中的字符串一致时，显示验证通过，不一致时显示验证未通过，并提示验证(查询)次数。
变形例
变形例中，二维码30中编入的信息为以下的网页链接，省略了物流码：
·http://www.abbott.com.cn/our-products/eleva.html
点阵100中编入以下的密码信息：
·129632153456。
用识读终端400读取二维码300时并解码时，直接链接上网，并进入以上链接指定的网页。
在该网页中提示：下载”雅培奶粉”app验证。其余与实施方式相同。
变形例除没有物流信息外，效果与实施方式相同。以上对组合二维码的防伪系统及验证方法进行了说明。
由以上实施方式可知，在本发明中，由于在普通的二维码30(QR码)中引入了点阵100，点阵100的表面被至少部分覆盖，编入点阵100的密码信息采用保密算法进行加密处理，大大增加了系统造假难度。并且，二维码30中编入的信息只是引导下载或启动验证软件的信息，点阵100的解码以及验证用信息的形成由验证软件完成，提高了通过伪造二维码和网站的进行系统造假的难度。
由于形成验证用信息的原始信息中包含物流码、产品序号或产品批次等不断变化的信息，因此，不同的物品或批次的二维码30图形(码图)均不相同，即，由于不同的物品或批次的二维码的图形发生变化(图形变码)，无法通过复制二维码来造假，进一步增加了造假的难度。
同时，由于二维码中编入物流码、营销信息和网址，从而实现了一码多用，大大节省了成本，做到了防伪、物流、营销一码化，解决了制造企业多年的难题。
以下对本发明的变形例进行说明。
变形例1
实施方式中，验证用数字由二维码中与物流码、产品序号、产品批次与点阵100中的密码信息构成，变形例中，直接使用点阵100中的密码信息进行验证。
实施方式中，验证在数据库进行，变形例中，下载APP验证软件时，同时将数据库中的字符串下载到识读终端，直接在识读终端本地验证，省略了与数据库的连接。
变形例2
实施方式中，直接将二维码30中的数字和点阵100中的密码连接在一起构成验证用数据，利用物流码、产品序号、产品批次等信息的变化，使二维码30的图形变码，变形例中，增加变码模块，由变码模块使编入二维码30中的信息产生变化。这样，即使编入二维码30的信息都是固定信息，也能使二维码30图形变码，提高造假难度。
在实施方式中，编入点阵100的信息是不变的，但点阵100也可采用图形变码，因为点阵100被至少部分覆盖，在覆盖层至少被部分去除前，点阵100不能被识读，起到了暗码防伪作用。
二维码30和点阵100的图形变码可单独使用也可组合使用。
实施方式中，验证用信息是直接由二维码30中的信息与点阵100中的密码信息组合而成，但也可以取其中的一部分组合成验证用信息。
以上实施方式及变形例中，生成二维码30以及点阵100的信息均存储在数据库中用于验证，如作为验证用信息编入二维码30的物流码、产品序号、产品批次等，编入点阵100的密码信息，以及组成验证用信息的算法等均存储在数据库中。
变形例
在图1至4中，点阵100的深色模块为圆点，与二维码30中的矩形模块的形状不同，在变形例中，点阵100中的模块的形状、大小、间距和位置与所述二维码30中的模块的形状、大小、间距和位置相同，因此，点阵100的图形不仅覆盖部分二维码30，由于点阵100的模块在视觉效果上与二维码30的模块保持一致，起到了隐藏点阵100图形的效果。
作为二维码30也可在生成时，预先生成供点阵100嵌入的空白部分，由于空白部分没有模块存在，点阵100嵌入空白部分时不会因遮挡二维码30的模块，造成二维码30读取时的误码，与利用二维码的纠错能力纠错点阵100引起误码的方案相比，可以降低二维码30的纠错等级、提高解码运算速度。
以上只是本发明的较佳实施方式和变形例，本领域的技术人员可应 用现有的技术，在本发明技术思想的范围内进行改动或替换。
