针对农业知识产权系统长期存在的农业科技成果确权耗时长、成本高、侵权举证困难、证据固定耗时久等问题，利用区块链去中心化、可追溯及不可篡改等技术特征，结合智能合约、IPFS、加密算法以及数字水印技术，提出一种基于联盟链的农业知识产权确权模型，通过设计知识产权登记和权利转让的预置机制智能合约，实现农业知识产权的自动化确权和转让过程。以国内农业种植技术领域专利为研究对象，构建知识产权保护系统，对模型进行功能模块实现与性能测试，结果表明该模型有良好的性能和较高的安全性，可实现农业知识产权的可信确权与版权溯源。

In response to the long-standing problems of the agricultural intellectual property system, such as the time-consuming and high cost of confirming the rights of agricultural scientific and technological achievements, the difficulty of proving infringement and the time-consuming fixing of evidence, a model of confirming the rights of agricultural intellectual property based on the federated chain is proposed by using the technical features of blockchain such as decentralization, traceability and immutability, and combining smart contracts, IPFS, cryptographic algorithms and digital watermarking technology, and by designing a smart contract for intellectual property registration and By designing a smart contract with a pre-set mechanism for the registration and transfer of rights, the process of confirming and transferring agricultural intellectual property rights can be automated. The model is tested for its functional modules and performance. The results show that the model has good performance and high security, and can achieve credible confirmation of agricultural intellectual property rights and copyright traceability.
