针对 RFID 标签在供应链中潜在的数据完整性问题，结合低成本标签在现有标准框架中应遵循的条件，分析现有标签篡改检测方法的不足，提出基于脆弱零水印的 RFID 标签篡改检测方法。将水印存放在后台数据库中，这种将水印和标签载体进行物理隔离的方法节省了标签的存储空间，且和现有标准相兼容。理论分析结果表明，与现有方法相比，该方案所采用的低复杂度算法易于实现，在没有增加各项指标都有限的低成本标签负担的基础上提高了 RFID 标签的安全性。

Aiming at the potential data integrity problems of RFID tags in the supply chains and combining the application condi-tions of the low cost tags in existing standard framework,the shortages of existing tamper detection method were analyzed,the tamper detection scheme of RFID tags based on fragile zero watermark was proposed.The watermark was put into the backend database in this scheme,which made the tag and watermark physically isolated in which way the memory of the tag was saved and existing standards were compatible with.Theoretical analysis demonstrates that the scheme with low complexity algorithms is easy to implement compared with the existing schemes,at the same time it improves the security of the RFID tags without adding extra cost in limited low cost tags.
