Description

微纹防伪识别方法 技术领域
本发明涉及一种防伪方法，尤其涉及一种微纹防伪识别方法。
背景技术
纹理防伪是以包装材料本身固有的斑纹记号为防伪识别标记的一种防伪技术。自然界的斑纹总是千差万别的，如指纹、木纹、石纹、斑马纹、冰纹、干裂的地面等纹理都是随机的、唯一的、不可能有两个完全一样的。利用这一原理，选用纹理清晰的包装材料制成防伪标签，对每一枚标签材料的斑纹记号进行拍摄、编号、建档、存入防伪数据库中。
随着条形码标签的广泛应用，如何保证条形码标签难以伪造、易于识别、长期有效，已经成为防伪行业国际公认的防伪技术产品优劣的评价标准。防止“盗码造假”一直是本领域的研究热点。本发明提供的微纹防伪识别方法，重点放在“如何防止被盗后的防伪数据用于造假”，而不像大多数同行那样将研究重点放在“如何防止防伪数据被盗”上。
由于印刷编码或印刷图文的扩散纹线是一条条随机弯曲的微曲线，具有随机性、唯一性、不可复制性。因此利用编码/图文等油墨边沿上凸起来的扩散纹(俗称毛刺)、或凹下去的扩散纹(俗称豁口)进行防伪识别，如图1中的扩散纹1，具有工艺简单，防伪数据难于造假的优点。但是直接利用印刷编码或印刷图文的扩散纹进行防伪，扩散纹特征可能不够清晰，缺乏个性化。此外，编码/图文扩散纹本身容易产生变形，褪色，最终大大增加了识别难度。
发明内容
本发明所要解决的技术问题是提供一种微纹防伪识别方法，能够形成具有随机扩散纹的图文标识，保证扩散纹清晰可见，易于识别，有效防止被盗后的防伪数据用于造假，且工艺简单，易于实施推广。
本发明为解决上述技术问题而采用的技术方案是提供一种微纹防伪识别方法，包括如下步骤：a)向承印物上编码标识或图文标识的印刷区内预先印刷扩散剂涂层； b)在扩散剂涂层上采用喷墨印刷形成具有随机扩散纹的编码标识或图文标识；c)对所印刷的编码标识或图文标识进行放大拍照，获取该编码标识或图文标识的扩散纹特征照片；d)存储编码标识或图文标识的扩散纹特征照片作为防伪特征备案信息。
上述的微纹防伪方法，其中，所述步骤b)中当编码标识或图文标识的扩散纹高度扩散达到0.03mm～0.05mm时，通过向印刷区内的编码标识或图文标识喷吸湿快干剂使得编码标识或图文标识上的扩散纹定型。
上述的微纹防伪方法，其中，所述步骤b)中的快干剂为硬脂酸甘油酯或油酸甘油酯，所述快干剂的喷洒质量为扩散剂涂层质量的3～5倍。
上述的微纹防伪方法，其中，所述步骤b)还包括对编码标识或图文标识进行随机切割，并在切割处形成扩散纹。
上述的微纹防伪方法，其中，所述步骤c)对具有扩散纹的图文标识采用物距小于390mm的微距放大拍摄方式，拍摄放大倍数为8～80倍。
上述的微纹防伪方法，其中，所述步骤d)首先对编码标识或图文标识进行比对，如果不一致直接反馈鉴定结论为假冒产品；如果编码标识或图文标识比对一致，则继续比对该编码标识或图文标识对应的扩散纹特征照片。
上述的微纹防伪方法，其中，所述步骤d)采用手机拍摄承印物上的编码标识或图文标识，以获取具有个性化扩散纹的实物现场照片，然后再将实物现场照片上传至计算机防伪网络查询系统进行鉴定；如果编码标识或图文标识相符，则反馈初步鉴定结论为真，并将最终鉴定结论的链接返回到用户手机上；在最终鉴定结论的链接被用户点开之前的一段时间里，计算机防伪网络查询系统将实物现场照片与预先备案存储的扩散纹特征照片进行分析比对，做出最终鉴定结论，并等待用户点开链接、获取最终结论。
上述的微纹防伪方法，其中，所述步骤b)还包括对编码标识或图文标识进行随机切割，并在切割处形成扩散纹；如果同一手机用户对同一编码标识或图文标识进行两次及两次以上的防伪查询，则先对用户上传的编码标识或图文标识进行比对验证，如果相符则继续对该编码标识或图文标识的扩散纹特征照片进行比对验证；如果仍相符，最后对该编码标识或图文标识上的随机切割线的形状和位置进行比对验证。
上述的微纹防伪方法，其中，所述编码标识为序列号、一维条码、二维码、生产日期、产品批号、防伪数码、促销积分码、兑奖码、防窜货编码或产品溯源码。
本发明对比现有技术有如下的有益效果：本发明提供的微纹防伪识别方法，通过在承印物预先印刷扩散剂涂层，使得编码标识或图文标识边沿形成清晰可见的扩散纹，存储图文标识及其对应的扩散纹特征照片一起作为防伪特征备案信息，易于识别，从而能够有效防止被盗后的防伪数据用于造假，且工艺简单，易于实施推广。
附图说明
图1为现有的采用扩散纹的二维码结构示意图；
图2为本发明的扩散纹微纹防伪识别过程示意图。
具体实施方式
下面结合附图和实施例对本发明作进一步的描述。
图2为本发明的扩散纹微纹防伪识别过程示意图。
请参见图2，本发明提供的微纹防伪识别方法，包括如下步骤：
步骤S1：向承印物上编码标识或图文标识的印刷区内预先印刷扩散剂涂层，以便更好地形成个性化的扩散纹；
步骤S2：在扩散剂涂层上采用喷墨印刷形成具有随机扩散纹的编码标识或图文标识；当编码标识或图文标识的扩散纹高度扩散达到0.03mm～0.05mm时，通过向印刷区内的编码标识或图文标识喷吸湿快干剂使得编码标识或图文标识上的扩散纹定型；
步骤S3：对所印刷的编码标识或图文标识进行放大拍照，获取该编码标识或图文标识的扩散纹特征照片；优选采用物距小于390mm的微距放大拍摄方式，拍摄放大倍数优选为8～80倍，以便能够从所拍摄的照片上、看清小至0.01mm～0.3mm的扩散纹；
步骤S4：存储编码标识或图文标识的扩散纹特征照片作为防伪特征备案信息。
为了更好地保证油墨扩散纹快速成型，便于后续拍照。所述快干剂可以为硬脂酸甘油酯或油酸甘油酯，所述快干剂的喷洒质量为扩散剂涂层质量的3～5倍，从而实现快干剂对扩散剂和颜料的充分包覆，提高干燥速度，保证扩散纹快干成型，不易变形，大大降低后续识别比对难度。
本发明提供的微纹防伪识别方法，为了更好地形成个性化的扩散纹，还可以对编码标识或图文标识进行随机切割，从而进一步在切割处形成个性化的扩散纹。此 外，随机的切割线本身也构成编码标识或图文标识的一部分，进一步增加仿制难度。
本发明提供的微纹防伪识别方法，首先对图文标识进行比对，如果不一致直接反馈鉴定结论为假冒产品；如果编码标识或图文标识比对一致，则继续比对该编码标识或图文标识对应的扩散纹特征照片，从而更快更好地满足用户的查询需求。随着手机物联网防伪技术的发展，为了更好地提升用户体验，所述步骤S3中采用手机拍摄承印物上的编码标识或图文标识，以获取具有扩散纹的编码标识或图文标识实物现场照片，然后再将实物现场照片上传至计算机防伪网络查询系统进行鉴定；如果编码标识或图文标识相符，则反馈初步鉴定结论为真，并将最终鉴定结论的链接返回到用户手机上；在最终鉴定结论的链接被用户点开之前的一段时间里，计算机防伪网络查询系统将实物现场照片与预先备案存储的扩散纹特征照片进行分析比对，做出最终鉴定结论，并等待用户点开链接、获取最终结论。此外，公众还可以使用手机调取预先备案存储的扩散纹特征照片，自我观察编码标识或图文标识及其扩散纹是否相符，从而判别真伪。
为了进一步提高识别准确率，对进行随机切割的编码标识或图文标识；如果同一手机用户对同一编码标识或图文标识进行两次及两次以上的防伪查询，则先对用户上传的编码标识或图文标识进行比对验证，如果相符则继续对该编码标识或图文标识的扩散纹特征照片进行比对验证；如果仍相符，最后对该编码标识或图文标识上的随机切割线的形状和位置进行比对验证。
虽然本发明已以较佳实施例揭示如上，然其并非用以限定本发明，任何本领域技术人员，在不脱离本发明的精神和范围内，当可作些许的修改和完善，因此本发明的保护范围当以权利要求书所界定的为准。
