The rapid development of the Internet and Internet of Things has rapidly introduced human society into the information age, and the way of fake news production has been updated, which has greatly affected the normal life of human beings. In order to identify worthless fake news and trace massive fake news data from unknown sources, and share valuable news data to fully disseminate effective real news, news owners usually store news data in cloud. Users of IoT terminals can access news data on demand without storing it locally. However, the authenticity of the fictive newspaper numbers source, which is easy to destroy, and the social media platform. Besides, when massive news data is saved on cloud server, the news owners have to at the risk of lose physical control over news data and it will face the risk of fake news being disseminated and real news being falsified. Thus, this paper proposes a novel mechanism for secure storage of news data using blockchain technology. Firstly, traceability and verification of fake news data is improved by the cooperative storage model on and off the chain. Secondly due to the inability of past polynomial commitment to update the commitment, we will be a hindrance to use polynomial commitment to build a secure authentication protocol. Therefore, in this paper, we design the update algorithm for polynomial commitment in order to be able to guarantee the consistency of on-chain and blockchain database news data.
互联网和物联网的快速发展迅速将人类社会带入信息时代，假新闻的制作方式也不断更新，这对人类的正常生活产生了极大影响。为了识别毫无价值的假新闻，追踪来自未知来源的大量假新闻数据，并分享有价值的新闻数据以充分传播有效的真实新闻，新闻所有者通常将新闻数据存储在云端。物联网终端用户可以按需访问新闻数据，而无需在本地存储。然而，虚构报纸数字来源以及社交媒体平台的真实性很容易被破坏。此外，当大量新闻数据保存在云服务器上时，新闻所有者不得不冒着失去对新闻数据实际控制权的风险，并且将面临假新闻被传播和真实新闻被篡改的风险。因此，本文提出了一种利用区块链技术安全存储新闻数据的新颖机制。首先，通过链上和链下的协同存储模型提高假新闻数据的可追溯性和验证性。其次，由于过去的多项式承诺无法更新承诺，这会阻碍我们使用多项式承诺构建安全认证协议。因此，在本文中，我们设计了多项式承诺的更新算法，以便能够保证链上和区块链数据库新闻数据的一致性。
