Multi-factor authentication for users of non-internet based applications of blockchain-based platforms

Abstract

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 blockchainbased asset financing platform is also discussed.

Using Smart Contracts in the Proposed Blockchain Framework for an Identity Management System Based on the Internet of Things

“…In addition, its utilization is common when monitoring elements like data amount, quality, and validity (Zheng et al, 2019;Guo et al, 2020). As demonstrated in the accompanying diagram, this offers more transparency and allows for creating a distinctive and global ID (Kinai et al, 2020;Xu et al, 2021;Cheng & Shaoqin, 2020;Wang et al, 2021).…”

“…A new online service requires a new username and password (Gong- Guo & Wan, 2021;Noh & Rhee, 2020). It's hard to remember several service login credentials (Kinai et al, 2020). In addition, keeping several authentication profiles up to date is difficult (Fang et al, 2022;Kim et al, 2022;Srivastava et al, 2019;Dhar et al, n.d.;Chalaemwongwan & Kurutach, 2018;Choi & Kim, 2020).…”

“…Thus, users can use the platform outside their nation to verify their identity (Ismail et al, 2022;Xue, 2022b). The many components of the proposed framework were taken from prior studies, books, articles, conference papers, and journals related to the blockchain (Dhar et al, n.d.;Chalaemwongwan & Kurutach, 2018;Choi & Kim, 2020;Gong-Guo & Wan, 2021;Noh & Rhee, 2020;Wang et al, 2020;Kinai et al, 2020;Xu et al, 2021;Cheng & Shaoqin, 2020;Wang et al, 2021;Ismail et al, 2022;Xue et al, 2022;Geetha & Balakrishnan, 2021;Patel et al, 2019;Cheng et al, 2022;Xue et al, 2022;Nikhitha & Kumara, 2020). Several studies on specific blockchain applications in various fields provide insight into technical issues, such as identity management systems and blockchain consensus methods.…”

Multihoming Big Data Network Using Blockchain-Based Query Optimization Scheme

“…A multiparty, interfered, traceable, and cooperatively maintained scattered database, Smart provides a strong safety net. Blockchain networks and [1] promote big data transparency and consistency and yet are broadly applied in health information retention [2], financing, supply chain [3,4], among information sharing areas [5] and many other arenas. One of the most significant barriers to blockchain implementation has been public acceptance.…”

“…Therefore, the association between dealings cannot be recognized, and the linking operation between the blockchain and in the blockchain is not maintained. (2) The linking query efficacy is small. In the chunks on the chain, connections are deposited, with no index among transactions.…”
