基于农产品溯源的二维码防伪系统设计

Design of Two-Dimensional Code Anti-Counterfeiting System based on Agricultural Products Traceability

二维码以其可容纳信息量大和价格低廉的优点,已在农产品溯源中得到了广泛应用。但是,农产品溯源中二维码水印防伪系统的应用研究仍处于起步阶段。当前,二维码的水印技术大多是对鲁棒性水印进行研究,但在农产品溯源的实际应用过程中,二维码水印应主要是为防止不法商贩对已加密的二维码进行扫码再打印,以保障农产品的唯一性。针对农产品溯源中二维码使用量大的特点,提出在农产品溯源的二维码水印系统中创建图像水印库,以增强二维码水印系统的安全性,保障农产品流通过程中的安全性。

The two-dimensional code is now widely applied in the traceability of agricultural products for its advantages of large amount information and low price. And however, the application research on the twodimensional code watermark anti-counterfeiting system in the traceability of agricultural products is still in its infancy. Currently, most research on two-dimensional code watermarking technology is concentrated on robust watermarking. However, in the actual application process of agricultural product traceability, the two-dimensional code watermark should mainly prevent the illegal traders from scanning and reprinting the encrypted two-dimensional code, thus to ensure the uniqueness of the agricultural products. According to the large amount use of two-dimensional code in the traceability of agricultural products, the construction of image watermark database in the two-dimensional code watermarking system of agricultural product traceability is proposed, thus to enhance the security of the two-dimensional code watermarking system and provide a reliable guarantee for the safety of agricultural products in the process of circulation.
