While promoting the vigorous development of crowdsourced testing services, Internet technology has also generated problems such as non-standard intellectual property management, unclear ownership of rights, and lack of trustworthiness. Based on the characteristics of being decentralized, traceable and tamper-proof of blockchain, IPFS, SHA256 algorithm, and digital certificate technology, this paper puts forward a new intellectual property management framework for crowdsourced testing to meet the requirements of intellectual property traceability of crowdsourced testing, right confirmation and query, and proposes the idea of applying on the chain and off chain decomposition and integration technology to address the storage performance bottleneck problem caused by data expansion on the chain, thus realizing a trusted intellectual property management system of crowdsourced testing. Meanwhile, this paper puts that the intellectual property of crowdsourced testing cannot be fully maintained only by technical means, and corresponding legal support means should be supplemented, including improving the laws and regulations on judicial and administrative protection of intellectual property, and properly handling the legal risk control of intellectual property of crowdsourced testing.
