基于RFID和数字水印技术的标签防伪验证方法

摘要

A new anti-tampering tag authentication method was proposed in this paper. By combining the distributed watermarking embedded RFID tag technology and the tamper-proof technology, storing data with watermark in multiple tags in order, a multi-layered watermarking authentication structure was constructed to ensure the integrity of electronic tags. Besides, the one-time pad encryption scheme based on a random numbers table was adopted to encrypt the keys, protecting the data in channels. The method realizes its goals namely preventing the data from being tampered and avoiding data being leaked. To test the method, a prototype system implementing the method was built, and ideal results were obtained. The method can be applied to many realistic scenes such as commodity warehousing and commodity certiifcate security, not only ensuring data security but also reducing costs for avoiding the usage of advanced intelligent electronic tags, and can be applied to many other ifelds.%文章提出一种全新的标签防伪验证方法。通过结合分布式射频识别技术（RFID）和数字水印技术（digital watermarking），将有效数据和水印有序地存储在多张标签中，构造一个多层水印验证结构，保护标签信息的完整性。在网络传输过程中，创新性地使用了一种基于随机密钥表的一次一密传输方法对密钥加密，以保证信道上数据的安全性，实现防止标签被篡改和避免数据泄露的功能。为了测试该方法，文章搭建了一套原型验证系统并获得了理想的结果。该标签防伪验证方法可用于商品入库检验以及商品证书防伪等场景，既能保证数据安全又能避免使用高级智能电子标签，降低了成本，应用前景十分广阔。
