Optimization of Information Security Sharing Mechanism of Online Education Platform based on Block Chain Technology

Under the ravages of the COVID-19, online education platform business has achieved rapid development, and excessive platform integration and the spread of paid knowledge have also spawned security problems of data sharing between platforms and users. Meanwhile, the development of Internet technology has also increased the difficulty of knowledge safeguarding rights on education platforms and cracking down on piracy. Based on the application characteristics of blockchain technology, this paper proposes a dual authentication mode of node + platform based on hash detection. Through the smart contract provided by Ethereum, data encryption linking and two-way verification between different platforms are realized. After linking to blockchain, data transmitted over the network can be protected from hacking and tampering. The research in this paper has an enlightening effect on promoting the integration development of blockchain technology and emerging industries, and also makes a specific judgment on the next integration development direction.
