基于二维码的木材运输防伪码单设计

通过对面积限额制度下的木材运输行为进行分析,提出为增强木材运输码单的防伪性能,采用加印二维码的防伪码单进行木材运输监管的设想,并详细介绍二维码的编码规则以及配套使用的硬软件设施;为增加二维码的加密性能,对需要进行二维码编码的信息运用校验和算法进行加密,设计出基于二维码技术的木材运输防伪码单。通过软件自动识别,该防伪码单能够有效提高林业管理部门的执法效率,对伪造码单、涂改码单信息的违法行为具有一定的抑制作用。

Design of Timber Transportation Anti-fake Checklist Using 2D Barcode

The paper analyzed the timber transportation behavior under woods harvest circumstance of the area quota system. In order to enhance the anti-fake ability of timber transportation checklist,a propose about checklist pasted with 2D barcode was put forward and its encoding rules,some relevant devices and software were also introduced. To fortify the encrypting function of 2D barcode,the checksum algorithm was applied to the encoding data. Finally,the timber transportation anti-fake checklist using 2D barcode was carried out. The anti-fake checklist can not only improve the checking efficiency of forest management department,but also restrain some illegal behaviors by automatic identification.
