论文摘要
针对数百万个基于非互联网的应用程序用户的攻击正在上升。这些应用程序（例如SMS和USSD）通常不会从现有的多因素身份验证方法中受益，因为它们的交互界面的性质和操作方式。为了解决这个问题，我们提出了一种方法，该方法根据区块链交易的证据与风险分析相结合，通过多因素身份验证增强区块链。用户如何执行交易的个人资料加班，并用于分析每个新事务的风险水平。如果将交易标记为高风险，我们将使用过去认可的区块链交易生成N因子层的身份验证层。还讨论了如何使用拟议方法在基于区块链的资产融资平台中对关键财务交易进行身份验证的证明。
Attacks targeting several millions of non-internet based application users are on the rise. These applications such as SMS and USSD typically do not benefit from existing multi-factor authentication methods due to the nature of their interaction interfaces and mode of operations. To address this problem, we propose an approach that augments blockchain with multi-factor authentication based on evidence from blockchain transactions combined with risk analysis. A profile of how a user performs transactions is built overtime and is used to analyse the risk level of each new transaction. If a transaction is flagged as high risk, we generate n-factor layers of authentication using past endorsed blockchain transactions. A demonstration of how we used the proposed approach to authenticate critical financial transactions in a blockchain-based asset financing platform is also discussed.
