防伪标签及防伪标签验证方法
相关申请的交叉引用
本申请要求于2018年03月09日提交中国专利局的申请号为201810198227.X、名称为“一种防伪方法、防伪标识及销售方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及防伪标签技术领域，具体涉及一种防伪标签及防伪标签验证方法。
背景技术
防伪标签是一种用于帮助用户对商品的真伪性进行鉴别的手段，用户可以对防伪标签的光学特征或电子信息特征等进行验证进而确定张贴了防伪标签的商品的真伪性。在一些实施方式中，通过采用随机图案形状或采用图形的随机排列或随机形态作为防伪标签，用户可以通过手机等设备获取待验商品的防伪标签图像与预存的原始防伪标签图像进行比对，从而验证待验商品的真伪。
这些防伪标签可以防止不法分子的一部分伪造手段，但是其防伪功能仍然存在较大的缺陷。例如，一些不法分子可能通过获取原始防伪标签的图像进行复制打印得到伪造标签，或将真实的防伪标签从正品商品上取下后再次张贴在假冒商品上，导致用户在对假冒商品进行验证时获得错误的反馈结果。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。通常在此处附图中描述和示出的本申请实施例的组件可以以各种不同的配置或组合来设计。
因此，以下对在附图中提供的本申请的实施例的详细描述并非旨在限制要求保护的本申请的范围，而是仅仅表示本申请的选定实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其再定义和解释。
请参照图1，本申请提供一种防伪标签，该防伪标签至少包括第一结构层、第二结构层、定位标识及位于第一结构层与第二结构层之间的片状或点状的防伪元素。
在本实施例中，防伪元素在防伪标签的识别验证中起主要作用，防伪元素可以具有一定的光学可识别特征，通过数据采集装置(如带有摄像头的移动终端、专用的图像采集装置或扫描仪等)获取待识别的目标防伪标签的图像后，可由数据采集装置或服务器从获取的目标防伪标签的图像中识别防伪元素的光学可识别特征，并转换为可进行逻辑比对处理的数字化数据；片状的防伪元素也包括条状或块状等形状。
在一个例子中，可在第一结构层100和第二结构层200之间随机的设置多个形状的防伪元素400，防伪元素400可以是片状或点状的特定材料的碎片或碎块。一个或多个防伪 元素400的分布和/或形状可以作为防伪元素400的光学可识别特征，例如，防伪元素400的位置、角度、面积大小、图形形状、轮廓形状、轮廓线段形状、轮廓线段长度、特征点的坐标位置和/或特征点与特征点之间的距离等。这里所说的轮廓包括但不限于防伪元素400的外边沿轮廓、内部镂空边沿轮廓、防伪元素400在某些观察角度下出现的色差分界线或色彩分界线；这里说的特征点包括但不限于防伪元素400上的构成轮廓的线段的拐点、转折点、端点、中心点等，也包括防伪元素400图形的中心点、内切圆圆心、外接圆圆心等，以上这些都可视为防伪元素的光学可识别特征。为了便于理解，在本实施例中，将原始防伪标签上的防伪元素的光学可识别特征称作“原始图数据”，将目标防伪标签上的防伪元素的光学可识别特征称作“目标图数据”。
定位标识300位于第一结构层100的表面或内部，例如，定位标识300可以印制于第一结构层100的表面，或将特定颜色、特定形状、特定位置和/或特定大小的定位标识嵌入第一结构层内部。
可选地，在本实施例中，将定位标识300像防伪元素400一样放置在第一结构层100与第二结构层200之间；这种定位标识可看作定位标识位于结构层表面的一个特例。
为了便于区分，定位标识300有别于防伪元素400。
可选地，请参照图3，在本实施例中，定位标识300有一部分位于第一结构层100的表面或内部，另一部分可以位于第二结构层200的表面或内部。
可选地，在本实施例中，请参照图4，定位标识300的形式可以包括：四边形框、限定出四边形区域的点或线段的组合，例如，限定出四边形顶点的线段或点的组合、限定出四边形四边的点或线段的组合等；又例如用四个一维码图形围成一个四边形。
可选地，在本实施例中，防伪元素400也可位于由定位标识300按一定算法虚拟出来的四边形区域内；根据定位标识300获得的四个顶点围成的四边形的两条对边采用射线延长，再按一定比例在两条射线上分别计算出两个点，计算出来的四个点围成的四边形就是虚拟出来的四边形。例如请参照图5，定位标识300可以为二维码，在定位标识300旁预设距离内映射出的矩形区域为设置防伪元素400的区域，右边的虚线框不是真实存在的。本实施例中的四边形区域也可以是其他形状。
在本实施例中，定位标识300和防伪元素400在防伪标签的识别验证中起主要作用，通过定位标识直接获得或对定位标识采用连线、延长、相交、虚拟算法等手段获得的四边形区域，这个区域即为由定位标识300所获得的设定区域，至少一部分防伪元素位于这个区域内。对目标防伪标签和原始防伪标签的这个设定区域内的图像进行图像变换；比如拍摄的目标防伪标签和原始防伪标签的图像中的定位标识所获得的设定区域是两个形状互不 相同的不规则四边形，经过图像变换后变换成相同形状和大小的图形，原始防伪标签和目标防伪标签的图像中由定位标识获得的设定区域内的图像变换到相同形状和尺寸后，设定区域内的每个防伪元素的光学可识别特征才具有可比性。比如同一张防伪标签的同一个防伪元素的同一个轮廓线段的顶点，将目标防伪标签的图像中这个顶点的位置与原始防伪标签的图像中这个顶点的位置进行比对，两个位置吻合率达到预设值，则判定这个光学可识别特征是有效的；可选地，也可对轮廓曲线形状和轮廓曲线位置的相似度或吻合率是否达到预设值，来判定轮廓曲线是否有效；最后根据光学可识别特征的有效率来得出目标防伪标签的真伪结果。
第一结构层100、第二结构层200中的一个为具有透光性的保护层，另一个结构层为商品500或防伪元素400的承载层，商品500也可以是商品的标签、标牌、包装、外壳等。
例如，再次请参照图1，第一结构层100为防伪元素400承载层，用于与商品贴合，定位标识300位于第一结构层100表面或内部，至少部分防伪元素400与第二结构层200的附着力大于与第一结构层100的附着力。第二结构层200为具有透光性的保护层，在第一结构层100上随机设置防伪元素400后覆盖第二结构层200，使得防伪元素400被固定于第一结构层100和第二结构层200之间。
在例如，请参照图6，第一结构层100可以为商品，定位标识300位于第一结构层100表面或内部。第二结构层200为具有透光性的保护层，在第一结构层100上随机设置防伪元素400后覆盖第二结构层200，使得防伪元素400被固定于第一结构层100和第二结构层200之间，至少部分防伪元素400与第二结构层200的附着力大于与第一结构层100的附着力，第二结构层200被揭下时部分防伪元素400与定位标识300分离。
又例如，请参照图7，第二结构层200为防伪元素400的承载层，第一结构层100为印制有定位标识300的具有透光性的保护层，在第二结构层200上随机设置防伪元素400后覆盖第一结构层100，使得防伪元素400被固定于第一结构层100和第二结构层200之间。
基于这种设计，由于本实施例提供的防伪标签中，防伪元素400随机分布的特性，使得的造假者难以批量地仿制防伪标签，并且仿制过程防伪元素400相对于定位标识300的任何细微移动都会导致仿制的防伪标签无法通过图像识别验证。
请再次参考图7，在本实施例中，至少一个防伪元素400与第二结构层200的附着力大于与第一结构层100的附着力。同时，第二结构层200与商品表面粘贴更牢固，第一结构层100与第二结构层200的附着力小于第二结构层与商品表面的附着力，如此，如果造假者在尝试将本实施例提供的防伪标签从商品上揭下时，会导致第一结构层100与第二结构层200分离，并且使至少一个防伪元素400与第一结构层100分离，进而使位于第一结构层100表面或内部的至少一部分定位标识300与至少一个防伪元素400分离。一旦防伪元 素400与定位标识300的分离，要将防伪元素400与定位标识300的相对位置恢复至分离前的状态难度极大，同时粘贴回去的防伪标签第一结构层表面效果也会明显有别于原装防伪标签的效果，从而可防止造假者将本实施例提供的防伪标签从正品上揭下后重新粘贴至假冒商品上。
可选地，在本实施例中，至少一个防伪元素400中的至少一个区域具有光泽表面，其中，光泽表面具有光学变色特性。
例如，防伪元素400可以采用素面的或带图案的普通金葱膜、幻彩金葱膜(glitter film)或亮片膜进行裁剪后得到的碎片。由于光泽的表面难以通过打印的方式仿制，本实施例提供的防伪标签可以防止造假者通过获取真实防伪标签的图像进行打印复制造假。光泽表面具有较强的反光特性，请再次参照图2，在防伪标签生产过程中防伪元素翘曲等原因，防伪元素的反光角度随机分布，在同一观察角度下防伪元素的反光强度也会有所差异；如果防伪元素400采用幻彩金葱膜(也叫七彩金葱膜)，不同反光角度的防伪元素400上可以看到五颜六色的色彩，改变观察角度或反光角度防伪元素的颜色深浅或颜色色彩也会发生变化。
又例如，在防伪元素400表面部分区域印刷没有光泽的油墨，剩下区域具有光泽表面。
进一步地，在本实施例中，至少一个防伪元素400的至少一个区域为具有至少两层结构的多角度变色反光材料，所述防伪元素的至少两个区域的反光率不同或反光角度不同。防伪元素400在不同的观察角度、光照角度或光照强度观察角度下不同区域可能会呈现出不同的颜色深浅或颜色色彩。如此，可以进一步防止造假者通过打印的方式伪造防伪标签。
请再参照图2，在另一个例子中，防伪元素400上随机设置有多个镂空图案等，这些镂空图案的分布和/或形状可以作为防伪元素400的光学可识别特征。
在一个例子中，防伪元素400其中一层为反光层，另外一层为颜色层。
在一个例子中，多个防伪元素400在相同观察角度下的反光率不同。例如，多个防伪元素400在随机布置时其朝向也可以是随机的，从而使得多个防伪元素400在相同的观察角度下的反光率不同。
可选地，在本实施例中，保护层裸露在空气中的一面为亚光面，可减少保护层反光对防伪元素400的成像的影响。
可选地，请参照图8，在本实施例中，防伪元素400具有一定厚度，防伪元素400所在区域的保护层的表面高度高于没有防伪元素400的区域的保护层表面高度。由于防伪元素400的厚度，可以在保护层上造成一定的凹凸感，造假者通过打印的方式仿造的防伪标签没有凹凸感，消费者可以通过简单触摸即可识别出打印的假冒防伪标签。
可选地，在本实施例中，当防伪标签包括承载层时，承载层可以为易碎、易破或易变形材料。例如，承载层可以为易碎纸、易破膜、粘胶、油漆、油墨等。确保承载层与商品的附着力大于承载层与保护膜的附着力，同时确保防伪元素与承载层的附着力大于防伪元素与保护膜的附着力，造假者在尝试将本实施例提供的防伪标签从商品表面揭下时，会导致承载层和防伪元素残留在商品上，同时由于承载层具有易碎、易破或易变形特性，使得造假者无法将防伪标签完整的移植到假冒产品上。
可选地，在本实施例中，保护层或承载层为不可逆形变材料，该可形变材料发生形变所需的力小于将保护层与承载层分离或将承载层与商品表面分离的力。这使得造假者在企图将保护层与承载层分离或将承载层与商品表面分离时，保护层或承载层受力产生不可逆形变，改变至少一部分防伪元素400与至少一部分定位标识300之间的相对位置，进而使得防伪标签一旦被揭下就报废。
进一步地，在本实施例中，承载层包括第一区域和第二区域，防伪标签粘贴于商品表面后，第一区域与商品表面的附着力大于与保护层的附着力，第二区域与商品表面的附着力小于与保护层的附着力；保护膜被揭下时，第一区域的承载层附着在商品表面上，第二区域的承载层附着在保护膜上。用户在对防伪标签进行鉴别时，一旦发现承载层存在破裂或不完整即可认为商品存在造假嫌疑。如此，可以进一步防止造假者将正品的防伪标签回收后粘贴到假冒商品上。数据采集装置或服务器也可通过检测承载层完整度来检测防伪标签的有效性。
可选地，在本实施例中，防伪标签上标识有检索码，不同的防伪标签的检索码互不相同。在对防伪标签进行验证时，通过检索码快速查找到服务器中预存的原始防伪标签上的防伪元素400的光学可识别特征数据，从而提高查找验证的效率。
进一步地，请参照图3在一个例子中，若所述防伪标签包含承载层，则所述防伪标签粘贴到商品表面后，所述承载层至少部分区域与商品表面的附着力大于与所述保护层的附着力。这样，在揭下防伪标签的过程中，首先会把承载层与保护层分离开，并导致定位标识与防伪元素分开。
请参照图10在另一个例子中，检索码可以与定位标识300结合在一起，例如，定位标识300为四边形框，检索码以二进制编码图形的形式通过预设的比特位排列方式分布在四边形框的内侧。可以理解的是，检索码也可以分布于四边形框的内侧或外侧某一边或某几边，本例中的四边形框也可以是四条没有相交的直线；另外检索码也可以位于防伪标签以外的地方。
请参照图11，本实施例还提供一种包括数据采集装置800和服务器900的验证系统， 该数据采集装置800可以为具有图像采集功能的电子设备，如手机、平板电脑或其他图像采集设备等。在一些情况中，数据采集装置800可以具有一定的数据或图像处理能力。数据采集装置800可与服务器900通信以及进行数据交互。
请参照图12，本实施例还提供一种防伪标签验证方法，该验证方法可应用于图11所示的验证系统，该验证方法可用于对本实施例提供的包含光泽表面防伪元素的防伪标签进行验证，下面对该方法的各个步骤进行详细阐述。
步骤S110，通过数据采集装置获取目标防伪标签在不同的观察角度、光照角度或光照强度下的图像，目标防伪标签的图像来自数据采集装置拍摄的照片或视频。
步骤S120，数据采集装置或服务器通过获得的至少两张目标防伪标签的图像，计算出目标防伪标签的至少两张图像中防伪元素的颜色变化程度，若颜色变化程度低于预设值，则确定目标防伪标签的为无效标签。
获取到目标防伪标签图像后，数据采集装置可在本地进行颜色比对处理，获得目标防伪标签的至少两张图像中防伪元素的颜色变化程度。或由数据采集装置将获得的至少两张图像发送至服务器，由服务器进行颜色比对处理，获得目标防伪标签的至少两张图像中防伪元素的颜色变化程度。
由于本实施例提供的防伪标签上的防伪元素具有光学变色特性，在观察角度、光照角度或光照强度改变时至少部分防伪元素的颜色深浅或颜色色彩会发生较明显变化，而通过打印生成的防伪标签的防伪元素不具有光学变色特性或光学变色特性不明显，因此，通过目标防伪标签在不同观察角度、光照角度或光照强度下的两张图像的颜色变化程度可以鉴别出防伪标签是不是无效标签。
请参照图13，本实施例还提供一种防伪标签验证方法，该防伪标签验证方法可以应用于图11所示的验证系统，该防伪标签验证方法可以用于本实施例提供的防伪标签进行验证，下面对该方法的各个步骤进行详细阐述。
步骤S210，通过数据采集装置获取目标防伪标签的图像，数据采集装置或服务器对基于目标防伪标签的图像中的定位标识所获得的设定区域的图像进行图像处理，获得该区域内的防伪元素的目标图数据。
在本实施例中，服务器预存有原始防伪标签的原始图数据。
步骤S220，服务器直接从数据采集装置接收目标防伪标签的目标图数据，或者服务器接收数据采集装置获取的目标防伪标签的图像并进行图像处理后间接获得目标防伪标签的目标图数据，并与服务器预存的原始图数据进行相似度或吻合度比对，获得目标防伪标签的真伪结果；或者服务器将目标防伪标签的原始图数据发送给数据采集装置，由数据采集 装置将目标图数据和原始图数据进行相似度或吻合度比对，获得目标防伪标签的真伪结果。
可选地，在本实施例中，防伪标签上还标识有检索码，服务器预存有原始防伪标签的检索码和原始防伪标签的原始图数据的对应关系。在步骤S210的基础上，数据采集装置或服务器对目标防伪标签的图像进行图像识别，获得目标防伪标签的检索码。
服务器直接或间接获得目标防伪标签的目标图数据和/或检索码，服务器根据目标防伪标签的检索码查找出相应的原始图数据，服务器将目标图数据与检索码对应的原始图数据进行相似度或吻合度比对，获得目标防伪标签的真伪结果。
另一个例子，服务器根据直接或间接获得的检索码查找出相应的原始图数据并发送给数据采集装置，数据采集装置将自己进行图像处理获得的目标图数据与接收到的原始图数据进行相似度或吻合度比对，获得所述防伪标签的真伪结果。
基于上述设计，本实施例提供的防伪标签验证方法中，验证过程中服务器与数据采集装置之间的交互的目标图数据、原始图数据都只有很少的数据量，如此可以节省数据交互的流量和时间，加快验证速度。

工业实用性
综上所述，本申请实施例提供的防伪标签及防伪标签验证方法，通过设置第一结构层、第二结构层、定位标识及位于第一结构层与第二结构层之间的片状或点状的光学可识别的防伪元素，并使至少一个所述防伪元素与所述第二结构层的附着力大于与所述第一结构层的附着力，使得造假者在试图将本申请提供的防伪标签揭下时，会使第一结构层和第二结 构层分离，从而改变至少一部分所述定位标识与至少一个所述防伪元素的相对位置，进而使得被揭开的防伪标签无法恢复至可通过鉴真检验的状态，防止了造假者将正品上的防伪标签回收重复利用粘贴至假冒商品上。同时，防伪元素具有光学变色特性避免了通过打印造假，承载层具有易碎、易破或易变形等特性，防伪标签被揭下来则自毁，防止了造假者将正品上的防伪标签粘贴到假冒产品上面进行造假的可能。

    所述数据采集装置或所述服务器通过获得的所述目标防伪标签的至少两张图像，计算出所述目标防伪标签的至少两张图像中所述防伪元素的颜色变化程度，若所述颜色变化程度低于预设值，则确定所述目标防伪标签为无效标签。
  14. 一种防伪标签验证方法，其特征在于，应用于包括数据采集装置和服务器的验证系统，所述防伪标签验证方法用于对权利要求1-12任意一项所述的防伪标签进行验证，所述服务器预存有原始防伪标签上的防伪元素的原始图数据；所述方法包括：
    通过数据采集装置获取目标防伪标签的图像，所述数据采集装置或所述服务器对基于所述图像中的定位标识所获得的设定区域内的图像进行图像处理，获得所述区域内的所述防伪元素的目标图数据；
    所述服务器将直接或间接获得的所述目标图数据与预存的所述原始图数据进行比对，获得所述目标防伪标签的真伪结果；或所述服务器将所述原始图数据发送至所述数据采集装置，并由所述数据采集装置将所述目标图数据与所述原始图数据进行比对，获得所述目标防伪标签的真伪结果。
  15. 根据权利要求14所述的方法，其特征在于，所述防伪标签上标识有检索码，所述服务器预存有原始防伪标签的检索码和原始防伪标签的原始图数据的对应关系；
    通过所述数据采集装置或所述服务器对所述目标防伪标签的图像进行图像识别， 获得所述目标防伪标签的检索码；
    通过所述服务器验证所述目标防伪标签真伪的步骤，包括：
    通过所述服务器直接或间接获得所述目标防伪标签的目标图数据和/或检索码，所述服务器根据所述检索码查找出相应的原始图数据，所述服务器将所述目标图数据与所述原始图数据进行比对，获得所述目标防伪标签的真伪结果；
    通过所述数据采集装置验证所述目标防伪标签真伪的步骤，包括：
    通过所述服务器直接或间接获得所述检索码，所述服务器根据所述检索码查找出相应的原始图数据并发送给所述数据采集装置，所述数据采集装置将获得的所述目标图数据与所述原始图数据进行比对，获得所述防伪标签的真伪结果。
