VisTAS: blockchain-based visible and trusted remote authentication system

Abstract

The information security domain focuses on security needs at all levels in a computing environment in either the Internet of Things, Cloud Computing, Cloud of Things, or any other implementation. Data, devices, services, or applications and communication are required to be protected and provided by information security shields at all levels and in all working states. Remote authentication is required to perform different administrative operations in an information system, and Administrators have full access to the system and may pose insider threats. Superusers and administrators are the most trusted persons in an organisation. “Trust but verify” is an approach to have an eye on the superusers and administrators. Distributed ledger technology (Blockchain-based data storage) is an immutable data storage scheme and provides a built-in facility to share statistics among peers. Distributed ledgers are proposed to provide visible security and non-repudiation, which securely records administrators’ authentications requests. The presence of security, privacy, and accountability measures establish trust among its stakeholders. Securing information in an electronic data processing system is challenging, i.e., providing services and access control for the resources to only legitimate users. Authentication plays a vital role in systems’ security; therefore, authentication and identity management are the key subjects to provide information security services. The leading cause of information security breaches is the failure of identity management/authentication systems and insider threats. In this regard, visible security measures have more deterrence than other schemes. In this paper, an authentication scheme, “VisTAS,” has been introduced, which provides visible security and trusted authentication services to the tenants and keeps the records in the blockchain.

Usable comprehensive-factor authentication for a secure time attendance system

“…Moreover, some recent multi-factor authentication studies have presented new categorizations for each factor (Ali et al, 2021;Yazid et al, 2019;Liu et al, 2020) that are different from the traditional four factors emphasized in this paper; thus, these new, categorized factors can be overlapping in terms of the traditional categorization. Although the above studies have mentioned usability, the term is interpreted in different ways.…”

“…Numerous multi-factor authentication schemes have been proposed so far, but it has been reported that real and practical implementation is little, since they require too much effort from the user with a security level not as expected (Wang et al, 2020). Also, using some unfriendly, high-tech factors may inhibit use of those schemes because it requires a high user skill level, and authentication devices are not available everywhere (Ali et al, 2021). This is in line with a study (Das et al, 2019) revealing that more userfriendly multi-factor authentication is relatively essential, though very few existing papers focus on user evaluation.…”

A Novel and Robust Hybrid Blockchain and Steganography Scheme

“…Public blockchains are generally preferred in applications where the participation of cryptocurrencies or the entire society is expected. On the other hand, private blockchains [41] are frequently preferred in cases where privacy and access are desired to be limited. Blockchains, which are designed to be integrated into hospital systems, are the preferred models of the digital services offered by states to their citizens and are implemented with blockchain technology.…”

“…Digitalization is one of the most promising tools for combating one of the world's most enduring challenges, corruption (Santiso, 2022). By incorporating IT into various government functions, the Philippines aims to create a more accessible and citizen-centric service (Ali et al, 2021).…”
