5 Identity Problems Blockchain Doesn’t Solve | by Blake
Recently, in [ 22 ], Cha et al. proposed a new authentication protocol based on blockchain for share and access management of IoT device information as a distributed attitude. In this protocol, there are three main entities called device, user, and blockchain connected gateway (BCG).

The driving idea of providing a decentralized OAuth2-based authentication and authorization solution within the context of the FIWARE platform for realizing a smart city is to substitute the centralized storage of security claims within a database by adopting a blockchain platform to have multiple instances of the knowledge base being distributed and consistent among the various organizations

As the industry’s leading blockchain services provider, IBM Blockchain Services has the expertise to help you build powerful solutions, underpinned by the best technology. More than 1,600 blockchain experts use insights from 100+ live networks to help you address three key design points: governance, business value and technology.
What is Blockchain Authentication? | Security Encyclopedia
Nevertheless, anonymous authentication on trust is not a trivial issue since trust evaluation usually conflicts with anonymity, which is a necessary privacy requirement in an open MCS environment. To tackle this problem, we leverage Intel Software Guard Extension (SGX) and propose a scheme to anonymously authenticate trust with trustworthy trust evaluation in a blockchain-based MCS system. …
How Two-Factor Authentication Works with Blockchain
The blockchain (Li et al., 2020, Nguyen and Kim, 2018) is a promising technology (Wang, Zhang, & Zhang, 2018) consisting of grouping data in blocks that are linked among each other with the hash of the previous blocks, and having participants to the blockchain agreeing on the new blocks to include within the blockchain, by running a distributed consensus algorithm tolerant …

Blockchain on Two-Factor Authentication! Recap. In our first series, we covered the following 6 articles: Review of top 7 modern cyber attacks for IT security professionals ; How Distributed Denial-Of-Service (DDoS) Attacks Work; How Advanced Persistence Threat works; What Is the Zero-Trust Approach in Cybersecurity; The assume breach approach in cybersecurity; The impact of the CIA security
Blockchain for digital identity - IBM Blockchain | IBM
Blockchain is increasingly being used to support authentication without passwords, says Rohas Nagpal achief architect at Primechain Technologies, a startup company. "When you onboard a user, his blockchain pubic key, private key and address gets generated and an RSA public key/private key gets generated," Nagpal explains in an interview with Information Security Media Group.
Decentralized Identity: An alternative to password-based
In the blockchain concept, the majority or even all network nodes check the validity and accuracy of exchanged data before accepting and recording them, whether this data is related to financial transactions or measurements of a sensor or an authentication message. In evaluating the validity of an exchanged data, nodes must reach a consensus in order to perform a special action, in which case
Verifying Product Authenticity with Blockchain Smart Contracts
The record in the blockchain is permanent and immutable, so the company can confirm that this invoice was re-sent by mistake. Confirm product certifications are unchanged. A consumer buys a certified diamond with an associated serial number on it. He backs up the diamond’s “warranty of authenticity” and proof of purchase with Acronis Notary.

Enable 2-Step Verification (2FA) – Blockchain Support Center
Blockchain has been disrupting the cybersecurity solutions-based CIA security triad principle. 2FA has been critical in security measures for several years; however, attackers sometimes manage to compromise these systems. We will understand how blockchain can transform the 2FA system to achieve an improved security method.
