二维码技术与防伪技术的联姻使用

来源:http://www.shengfengyinshua.com/ 日期:2020-07-22 发布人:shengfeng 二维码是一种信息载体,二维码编码是指二维码中所存储的信息内容。目前有众多的防伪厂商选择用二维码承载产品的防伪信息,并通过网络实现防伪验证。但不少企业都选择在二维码中只存储自定义防伪验证信息,由于大多数防伪信息系统都是封闭的验证系统,二维码中如果只存储自定义防伪验证信息,将不能保证大众手机中装备的各类APP扫描识读后进行相关的信息访问,且不能保证实现系统之间互联互通,为此,建议在二维码编码中,充分利用二维码能够兼容多种编码的优势,采用通用的二维码编码数据结构,将防伪验证信息作为一个标准数据项纳入到成熟通用的通用编码数据结构或URI数据结构中。
Two dimensional code is a kind of information carrier, two-dimensional code refers to the information content stored in the two-dimensional code. At present, many anti-counterfeiting manufacturers choose to use two-dimensional code to carry the anti-counterfeiting information of products, and realize the anti-counterfeiting verification through the network. However, many enterprises choose to store only user-defined anti-counterfeiting verification information in QR codes. Because most anti-counterfeiting information systems are closed verification systems, if only user-defined anti-counterfeiting verification information is stored in QR codes, it will not guarantee that all kinds of apps equipped in popular mobile phones can access relevant information after being scanned and read, and the interconnection between systems can not be guaranteed, It is suggested to make full use of the advantages of the two-dimensional code that can be compatible with multiple codes, and adopt the general two-dimensional code data structure, and incorporate the anti-counterfeiting verification information into the mature universal international common coding data structure or URI data structure as a standard data item.
二维码符号与标签印制方面
QR code symbol and label printing
二维码符号是一个图形符号,为防止二维码被批量拷贝、复制或非授权识读,应考虑与多种防伪技术进行集成,例如:在二维码符号上加印防复制图层;二维码印制基材采用纹理、材料防伪技术进行保护;二维码符号进行部分遮盖,刮开或破坏包装后才可以识读等。为保证二维码防伪技术方案的方便验证特性,一般不建议采用非标准、非通用码制作为二维码信息载体。

The QR code symbol is a graphic symbol. In order to prevent the QR code from being copied, copied or read without authorization, it should be considered to integrate with a variety of anti-counterfeiting technologies, such as: printing an anti duplication layer on the QR code symbol; using texture and material anti-counterfeiting technology to protect the printed substrate of QR code; partially covering the QR code symbol and reading it after scraping or damaging the package 。 In order to ensure the convenient verification characteristics of two-dimensional code anti-counterfeiting technical scheme, it is generally not recommended to use non-standard and non-general code system as the information carrier of two-dimensional code.
此外,防伪技术厂商应关注二维码的符号印制质量,特别是需要考虑兼容多种智能手机和多种识读环境的情况下,应保证二维码在增加了各种防伪保护措施后仍可以方便识读。如果需要大众通过手机扫描识读,则应保证防伪标签上印制的二维码符号质量等级不低于GB/T23704《信息技术自动识别与数据采集技术二维条码符号印制质量的检验》标准中规定的1.5级。
In addition, anti-counterfeiting technology manufacturers should pay attention to the printing quality of the two-dimensional code, especially in the case of compatibility with a variety of smart phones and a variety of reading environments, and ensure that the QR code can be read easily after adding various anti-counterfeiting protection measures. If it is necessary for the public to read through mobile phone scanning, the quality level of two-dimensional code symbols printed on the anti-counterfeiting label shall not be lower than level 1.5 specified in GB / t23704 "information technology automatic identification and data acquisition technology - Inspection of printing quality of two-dimensional bar code symbols".
3.二维码防伪信息系统建设问题
3. The construction of two-dimensional code anti-counterfeiting information system
二维码防伪信息系统建设除了需要考虑到防伪验证方面的需求之外,也需要考虑到二维码信息追溯、二维码信息服务与扫描用户统计等功能。特别需要注意的是,目前各防伪企业建立的、号称能够实现防伪追溯等功能的二维码服务信息系统完全封闭,其他信息系统无法通过标准接口获得与二维码相关的公开信息服务,供应链中的过程动态数据也无法在平台上进行体现,这是目前的突出问题。
In addition to the requirements of anti-counterfeiting verification, the construction of QR code anti-counterfeiting information system also needs to consider the functions of QR code information traceability, QR code information service and scanning user statistics. It should be noted that the QR code service information system established by various anti-counterfeiting enterprises and claimed to be able to realize anti-counterfeiting traceability and other functions is completely closed. Other information systems can not obtain the public information service related to QR code through standard interface, and the process dynamic data in the supply chain can not be reflected on the platform, which is a prominent problem at present.
