Description

随机致畸变的防伪方法、防伪标签及其应用系统 技术领域
本发明涉及防伪的技术领域，具体而言，涉及一种随机致畸变的防伪方法、防伪标签及其应用系统。
背景技术
通过数据库防伪图片比对实物图片是防伪技术的一个重要发展方向，特别是随着互联网和手机的快速发展，消费者可以随时随地访问网络数据库中的防伪图片，为消费者随时将数据库中的防伪图片与实物图片进行对比鉴别真伪提供可能。对于这种防伪方式，防伪效果好坏的一个重要环节就是如何制备出无法仿制的“唯一”防伪实物。目前的技术只能通过在一个“随机”维度上制备出防伪图案，即在标签或者包装物表面随机撒一定大小的纤维丝标志物，通过纤维丝组成的实物图案与前期采集的并存储与数据库中的该实物图案进行对比来进行防伪。该方法防伪效果随机维度只有一个，即纤维丝的分布随机维度。不法分子只需突破这个维度就可能制备出假冒产品，例如不法分子通过拿到的一个该防伪标签，然后通过手动人为或者机器摆放每根纤维丝的位置信息即可仿造出无数个假冒产品，防伪效果明显不够完美。

或者方式4：将畸变颗粒随机撒在载体层上，然后将含有粘接胶层的膜层经覆膜机压制在畸变颗粒和载体层表面，固定形成特征图案；
又或者方式5：所述畸变颗粒为天然菜籽或天然菜籽的破碎物，将天然菜籽或天然菜籽的破碎物撒在载体层表面，通过带压钢棍挤压天然菜籽变形，并将含粘接胶层的膜层经覆膜机压制在畸变颗粒和载体层表面上，待冷却稳定后，变形后的天然菜籽或天然菜籽的破碎物形成特征图案。
其中，优选地，上述方式1中畸变颗粒的尺寸范围为0.88-1毫米。
优选地，上述方式2中畸变颗粒的尺寸范围为1.7-2.36毫米。
进一步地，所述载体层表面还印有一层信息层，该信息层含有二维码；
所述防伪信息至少包括以下一种信息：畸变颗粒在标签表面的坐标位置信息、畸变颗粒变形后的图案信息、畸变颗粒颜色信息、畸变颗粒纹理信息、二维码信息。
本发明解决上述第一个技术问题所采用的另一个技术方案是：该随机致畸变的防伪方法，包括以下步骤，
S1、选取畸变颗粒，所述畸变颗粒随机形成，畸变颗粒能受力畸变形成随机形状；
S2、将畸变颗粒固定于载体层上方，所述畸变颗粒在载体层上受力畸变并固定成特征图案，特征图案为随机图案；
所述特征图案作为防伪信息被采集存储于数据库中，供授权用户进行比对查询真伪。
本发明解决上述第二个技术问题所采用的技术方案是：一种防伪标签，包括载体层和畸变颗粒，所述畸变颗粒受力畸变并固定于载体层上。

与现有技术相比，本发明的有益效果是：
本发明的随机致畸变防伪方法、防伪标签、及其防伪应用系统，由于使用了畸变颗粒，在防伪标签制作过程中，畸变颗粒几何外貌具有“随机性”；依靠该“随机性”的立体外形受力畸变在标签中，从而获得一个“随机性”的几何形状，畸变颗粒在防伪标签上存在多个维度的“随机性”，大大提高了防伪标签的防伪性能。
由于畸变颗粒为膜层覆盖，防伪标签多维度具有“自毁”特性，即仿冒者试图获得多维度的纹理特征时需打开外部膜，由于保持畸变“颗粒”畸变特性的外力消失，畸变“颗粒”由于具有一定弹力而恢复到原先未畸变时的形貌，那么这种“畸变”所带有的“随机”特征也立刻随着外力的消失而消失，这种“畸变”是一种动态“畸变”，也大大增加了防伪特性。
克服了单维度防伪技术的不足，引入了“外貌”随机性、“畸变”随机性和纹理“畸变”多个随机维度，上述多个随机维度结合过程极大的增加通过纹理防伪的安全性；同时，引入“动态平衡“防伪的特点，增加仿造难度，提高了防伪安全性。上述防伪独特优点，使得通过该发明获得的产品具有高度可靠“唯一性”特点。

以下结合附图实施例对本发明作进一步详细描述。
防伪方法实施例1
本发明随机致畸变的防伪方法的第一个实施例，包括以下步骤：
S1、选取畸变颗粒3，所述畸变颗粒3随机形成，畸变颗粒3由整块的畸变块随机破碎形成小颗粒的畸变颗粒3，每个畸变颗粒3形状不同，畸变颗粒3能受力畸变形成随机形状；
S2、将畸变颗粒3固定于载体层1上，所述畸变颗粒3在载体层1上受力畸变并固定成特征图案，特征图案为随机图案；
特征图案作为防伪信息被采集存储于数据库中，供授权用户进行比对查询真伪。
具体的，在所述步骤S2中，所述畸变颗粒3在标签上受力畸变成特征图案的方式为方式1，包括：
如图1所示，先在载体层1表面涂上不干胶，形成不干胶层6，然后在不干胶层6上随机撒畸变颗粒3，畸变颗粒3自身具有唯一性的纹理特征，畸变颗粒3尺寸为0.88-1毫米；随即然后在140度的温度下，将透明PET膜(即膜层4)通过覆膜机(图1中的覆膜工艺)压制在畸变颗粒3(弹性颗粒)和不干胶层6上，待冷却稳定后，形成特征图案；
为提升防伪性，载体层1表面还印有信息层2，信息层2为二维码；二维码也可以用其他的唯一性编码或者条形码来代替；防伪信息包括畸变颗粒3在标签表面的坐标位置信息、畸变颗粒3变形后的图案信息、畸变颗粒3颜色信息、畸变颗粒3纹理信息、二维码信息。在该产品使用中，首先通过拍照装置将防伪标签图片信息拍照，并存储于 数据库中。然后，将防伪标签贴在相应的产品上，例如，通过载体层1底部增加不干胶层来粘附在使用物体上。查询时，授权用户通过输入序列号、扫描二维码或者上传标签照片，经由人工或者计算机对比数据库中图片和使用物体上的图片辨别真伪。
防伪方法实施例2
本发明防伪方法的第二个实施例，其与上述防伪方法实施例1的区别点在于：
在所述步骤S2中，所述畸变颗粒3在标签上受力畸变形成特征图案的方式为方式2，包括：
如图2所示，先在载体层1表面涂上不干胶，形成不干胶层6，然后在不干胶层6上随机撒颗粒较大的畸变颗粒3，该畸变颗粒3尺寸为1.7-2.36毫米；然后滚轴压力下破碎成颗粒较小的小畸变颗粒31，随即将透明PVA膜(即膜层4)通过覆膜机覆膜，将破碎后的小畸变颗粒31与不干胶层6压制稳定，形成特征图案。
防伪方法实施例3
本发明防伪方法的第三个实施例，其与上述防伪方法实施例1的区别点在于：
在所述步骤S2中，所述畸变颗粒3在标签上受力畸变成特征图案的方式为方式3，包括：
如图3所示，将具有纹理特征、一定弹性的固体状颗粒较大的畸变颗粒3破碎成0.115-0.125毫米大小的畸变颗粒3，然后将该畸变颗粒3与可干胶混合，均匀涂抹在载体层1上，再在钢棍下滚压成型，并干燥可干胶，待稳定后，制成防伪标签；
畸变颗粒3可以完全浸没在可干胶(即可干胶层5)内，畸变颗粒3也可以部分露在外面，露在可干胶外部的畸变颗粒3浸透了可干胶，露出的畸变颗粒3随着可干胶固定，由于畸变颗粒3的结构固定不变，因此特征图案也是随机的。
防伪方法实施例4
本发明防伪方法的第四个实施例，其与上述防伪方法实施例1的区别点在于：
在所述步骤S2中，所述畸变颗粒3在标签上受力畸变成特征图案的方式为方式4，包括：
如图4所示，将具有纹理特征、一定弹性的固体状颗粒较大的畸变颗粒3破碎成0.38-0.5毫米的畸变颗粒3，再将其撒在载体层1上，然后在100度的温度下，将透明含有粘接胶层61的BOPP膜(即膜层4)通过覆膜机压制在畸变颗粒3和标签上，待冷却稳定后，得到防伪标签；
防伪方法实施例5
本发明防伪方法的第五个实施例，其与上述防伪方法实施例1的区别点在于：
在所述步骤S2中，所述畸变颗粒3在标签上受力畸变成特征图案的方式为方式5，包括：
如图5所示，选取天然的菜籽在100摄氏度干燥24小时，将干燥后的菜籽作为畸变颗粒3洒在上述标签上，随即然后在140度的温度下，通过带压钢棍挤压，并将透明含有粘接胶层61的PET膜(即膜层4)通过覆膜机压制在畸变颗粒3和载体层1上，待冷却稳定后，制备成防伪标签。菜籽内含有植物油，在被挤压破碎后，油脂渗出，油脂会在标签上形成油印，该油印为随机形状，具有唯一性，同时，菜籽也会被压扁形成扁状图案，也具有唯一性。
防伪标签实施例1
如图6所示，为本发明防伪标签的第一个实施例。该防伪标签包括从下至上依次分布的载体层1、信息层2、不干胶层6、畸变颗粒3和膜层4。
其中，所述畸变颗粒3受力畸变并固定于载体层1上。载体层1为铜版纸，铜版纸表层涂有不干胶，形成不干胶层6。
畸变颗粒3为可变形多孔材料颗粒、天然菜籽或者其破碎物。可变形多孔材料颗粒例如可以使发泡形成的乳胶颗粒或者棉线球，乳胶颗粒空隙较大，纹理清晰。
载体层1表面上设置信息层2，信息层2表面上设置不干胶层6，所述信息层2为二维码或序列号或编码，本实施例为二维码。
可变形多孔材料颗粒中含有荧光材料、反光材料、发光材料、磷光材料、紫外发光材料、感温材料中一种或者几种。增加此类材料，便于消费者在不同的光线环境下观察、感知该防伪标签。
本实施例中，畸变颗粒3与载体层1之间的连接方式为：畸变颗粒3位于铜纸板的不干胶层6上，所述不干胶层6表面覆盖膜层4，所述膜层4将畸变颗粒3压紧并变形固定在不干胶层6上，如图6所示。
膜层4将多孔材料颗粒压扁在铜纸板表面，多孔材料颗粒本身的立体纹理结构是独一无二，在被膜层4压扁之后，再次形成独一无二的图案，再结合多孔材料颗粒在铜版纸上的位置信息、相对于二维码的位置信息、信息层2上记载的二维码信息或者编码信息，从多个维度确保该防伪标签的“唯一性”，提升防伪标签的防伪性能；
同时该防伪标签具有“自毁性”，即仿冒者试图仿冒多维度的纹理特征时需打开外部膜，由于保持畸变“颗粒”畸变特性的外力消失，畸变“颗粒”由于具有一定弹力而恢复到原先未畸变时的形貌，那么这种“畸变”所带有的“随机”特征也立刻随着外力的消失而消失，这种“畸变”是一种动态“畸变”，也大大增加了防伪特性。
畸变颗粒3选用天然菜籽或其破碎物的时候，在被膜层4压扁之后的形状也是唯一 的，以及从菜籽从渗出的油渍纹路也是唯一的，从而提升防伪标签的防伪性。
防伪标签实施例2
如图7所示，为本发明防伪标签的第二个实施例。该防伪标签与防伪标签实施例1的区别点在于畸变颗粒3与载体层1之间的连接方式。
具体地，所述载体层1表面覆盖有可干胶层5，所述畸变颗粒3混合于可干胶层5内，随可干胶层5固化后固定于可干胶层5内。如图7所示，在此种连接方式中，省去了膜层4，通过可干胶直接固定可变型多孔材料颗粒。
畸变颗粒3可以完全浸没在可干胶(即可干胶层5)内，畸变颗粒3也可以部分露在外面，露在可干胶外部的畸变颗粒3浸透了可干胶，露出的畸变颗粒3随着可干胶固定，畸变颗粒3的结构是固定不变的，因此特征图案也是随机的。
可变形多孔材料颗粒由大块可变形多孔材料颗粒破碎形成，因此，每块可变形多孔材料颗粒的立体形状都是唯一的，在可干胶层5内混合固化中，变化的形状也是唯一的，在结合可变形多孔材料颗粒在铜版纸上的位置信息、相对于二维码的位置信息、信息层2上记载的二维码信息或者编码信息，从多个维度确保该防伪标签的“唯一性”，提升防伪标签的防伪性能；
同时该防伪标签具有如同防伪标签实施例1那样的“自毁性”。
本发明还提供了一种随机致畸变防伪标签的应用系统，其包括上述的防伪标签、识别设备、存储有防伪二维码识别数据库的服务器。
其中，所述识别设备适于对所述防伪标签进行扫描拍照并将多个分布物的物理防伪信息并存储于服务器中；
所述服务器适于依据地址信息以及多个分布物的物理防伪信息访问防伪标签识别数据库，并将物理防伪信息与数据库存储的防伪信息进行比对并进行防伪判断，根据判断结果将反馈信息回馈到识别设备上。
综上所述，本发明实施例提供了一种带有随机致畸变特征的防伪方法、防伪标签及其应用系统。本发明克服了现有防伪技术随机位置单维度防伪的不足。
最终防伪产品同时含有颗粒物理分布“随机性”、颗粒几何外貌的“随机性”、畸变的“随机性”，其纹理在畸变过程中也具有“随机性”，上述防伪的独特优点使得通过该发明获得的产品具有高度可靠的“唯一性”，极大的提高了产品的防伪性能。
以上述依据本发明的理想实施例为启示，通过上述的说明内容，相关工作人员完全可以在不偏离本项发明技术思想的范围内，进行多样的变更以及修改。本项发明的技术性范围并不局限于说明书上的内容，必须要根据权利要求范围来确定其技术性范围。
