Self-sovereign identity is a type of decentralized identity technology and has been proposed to solvevarious problems of the existing public key infrastructure based centralized identity authenticationservice. In addition, the demand for a secure decentralized access control management (ACM)technique has increased according to the demand for such next-generation identity identificationservice. Accordingly, although various ACM techniques that can be applied to decentralized serviceshave been proposed, most fall into the introductory stage of research. In this paper, based on theSOVRIN-based restructured verifiable credential concept proposed in our previous study, we providea hierarchical sovereignty and ACM technique that does not use a smart contract.

Full textAbstract:
Most of the existing identity management is the centralized architecture that has to validate, certify, and manage identity in a centralized approach by trusted authorities. Decentralized identity is causing widespread public concern because it enables to give back control of identity to clients, and the client then has the ability to control when, where, and with whom they share their credentials. A decentralized solution atop on blockchain will bypass the centralized architecture and address the single point of the failure problem. To our knowledge, blockchain is an inherited pseudonym but it cannot achieve anonymity and auditability directly. In this paper, we approach the problem of decentralized identity management starting from the designated-verifier anonymous credential (DVAC in short). DVAC would assist to build a new practical decentralized identity management with anonymity and auditability. Apart from the advantages of the conventional anonymous credential, the main advantage of the proposed DVAC atop blockchain is that the issued cryptographic token will be divided into shares at the issue phase and will be combined at the showing credential phase. Further, the smooth projective hash function ( SPHF in short) is regarded as a designated-verifier zero-knowledge proof system. Thus, we introduce the SPHF to achieve the designated verifiability without compromising the privacy of clients. Finally, the security of the proposed DVAC is proved along with theoretical and experimental evaluations.

Full textAbstract:
Blockchain (BC) has recently paved the way for developing Decentralized Identity Management (IdM) systems for different information systems. Researchers widely use it to develop decentralized IdM systems for the Health Internet of Things (HIoT). HIoT is considered a vulnerable system that produces and processes sensitive data. BC-based IdM systems have the potential to be more secure and privacy-aware than centralized IdM systems. However, many studies have shown potential security risks to using BC. A Systematic Literature Review (SLR) conducted by the authors on BC-based IdM systems in HIoT systems showed a lack of comprehensive security and risk management frameworks for BC-based IdM systems in HIoT. Conducting a further SLR focusing on risk management and supplemented by Grey Literature (GL), in this paper, a security taxonomy, security framework, and cybersecurity risk management framework for the HIoT BC-IdM systems are identified and proposed. The cybersecurity risk management framework will significantly assist developers, researchers, and organizations in developing a secure BC-based IdM to ensure HIoT users’ data privacy and security.

Full textAbstract:
COVID-19 has made eHealth an imperative. The pandemic has been a true catalyst for remote eHealth solutions such as teleHealth. Telehealth facilitates care, diagnoses, and treatment remotely, making them more efficient, accessible, and economical. However, they have a centralized identity management system that restricts the interoperability of patient and healthcare provider identification. Thus, creating silos of users that are unable to authenticate themselves beyond their eHealth application’s domain. Furthermore, the consumers of remote eHealth applications are forced to trust their service providers completely. They cannot check whether their eHealth service providers adhere to the regulations to ensure the security and privacy of their identity information. Therefore, we present a blockchain-based decentralized identity management system that allows patients and healthcare providers to identify and authenticate themselves transparently and securely across different eHealth domains. Patients and healthcare providers are uniquely identified by their health identifiers (healthIDs). The identity attributes are attested by a healthcare regulator, indexed on the blockchain, and stored by the identity owner. We implemented smart contracts on an Ethereum consortium blockchain to facilities identification and authentication procedures. We further analyze the performance using different metrics, including transaction gas cost, transaction per second, number of blocks lost, and block propagation time. Parameters including block-time, gas-limit, and sealers are adjusted to achieve the optimal performance of our consortium blockchain.

The fifth-generation mobile communication technology (5G) provides high-bandwidth and low-latency data channels for massive IoT terminals to access the core business network. At the same time, it also brings higher security threats and challenges. Terminal identity authentication is an important security mechanism to ensure the core business network; however, most of the existing solutions adopt a centralized authentication model. Once the number of authentication requests exceeds the processing capacity of the authentication center service, it will cause authentication request congestion or deadlock. The decentralized authentication model can effectively solve the above problems. This article proposes a decentralized IoT authentication scheme called A2 Chain. First, A2 Chain uses edge computing to decentralize the processing of authentication requests and eliminate the burden on authentication services and the network. Second, to implement cross-domain identity verification of IoT devices, A2 Chain uses blockchain, and sidechain technologies are used to securely share the identity verification information of IoT devices. Additionally, A2 Chain replaces public key infrastructure (PKI) algorithm with identity-based cryptography (IBC) algorithm to eliminate the management overhead caused by centralized authentication model.

Identity management is a critical component of cybersecurity, ensuring that only authorized individuals can access sensitive systems and data. Traditional identity management systems, which rely on centralized databases, face growing challenges related to data breaches, unauthorized access, and identity theft. Blockchain technology, with its decentralized, transparent, and tamper-resistant nature, has emerged as a promising solution to enhance identity management frameworks and improve overall cybersecurity.This paper proposes a novel identity management framework leveraging blockchain technology to address the limitations of conventional systems. The proposed system utilizes blockchain's immutable ledger to securely store and verify digital identities, eliminating the need for centralized databases and mitigating the risk of data breaches and identity fraud.Zero-knowledge Self-sovereign identities (SSI) cryptography a key feature of blockchain, empowers individuals to control and manage their own identity data, granting them the ability to selectively share information with trusted entities without relying on intermediaries. The novelty of this approach lies in the integration of blockchain's smart contracts for automated, conditional access control and cryptographic techniques to ensure user privacy and security. By combining these technologies, the system enables the dynamic issuance of identity verifications, such as multi-factor authentication (MFA) tokens, on-demand, reducing reliance on static credentials and enhancing resistance to phishing and credential theft. This decentralized model not only improves security but also enhances user experience by providing a unified and simplified approach to digital identity management. Through extensive analysis, the paper demonstrates how the adoption of blockchain in identity management can significantly reduce cybersecurity risks, such as unauthorized access, data breaches, and identity theft. The proposed framework promises to redefine digital identity management by providing a more secure, private, and user-centric model, which is essential in the evolving landscape of cybersecurity.

Due to the exponential rise of the Internet in the last two decades, the digital presence has seen an enormous increase. Today, billions of people, devices and objects are digitally connected making the interactions much easier than before. To securely establish this connectivity in the digital era, proving digital identities has become crucial. Due to this, a growing number of organizations are building solutions that establish, verify and manage digital identities. Yet, a solution whereby digital identities and their associated data are efficiently managed is still far from being achieved. To fully understand the reason behind this lack, this paper provides a detailed state of the art related to identity management systems. It overviews traditional systems, analyses their strengths and limitations. This work highly focuses on the novel decentralized identity systems based on blockchain; a complete study describing their architecture, components, lifecycle and workflow is detailed. Additionally, solutions enabling decentralized identity are discussed, analysed and compared according to the ten principles of self-sovereign identity. Lastly, the challenges hindering the shift toward the fully decentralized identity paradigm are discussed.

Full textAbstract:
The Internet of Things (IoT) paradigm aims to enhance human society and living standards with the vast deployment of smart and autonomous devices, which requires seamless collaboration. The number of connected devices increases daily, introducing identity management requirements for edge IoT devices. Due to IoT devices’ heterogeneity and resource-constrained configuration, traditional identity management systems are not feasible. As a result, identity management for IoT devices is still an open issue. Distributed Ledger Technology (DLT) and blockchain-based security solutions are becoming popular in different application domains. This paper presents a novel DLT-based distributed identity management architecture for edge IoT devices. The model can be adapted with any IoT solution for secure and trustworthy communication between devices. We have comprehensively reviewed popular consensus mechanisms used in DLT implementations and their connection to IoT research, specifically identity management for Edge IoT devices. Our proposed location-based identity management model is generic, distributed, and decentralized. The proposed model is verified using the Scyther formal verification tool for security performance measurement. SPIN model checker is employed for different state verification of our proposed model. The open-source simulation tool FobSim is used for fog and edge/user layer DTL deployment performance analysis. The results and discussion section represents how our proposed decentralized identity management solution should enhance user data privacy and secure and trustworthy communication in IoT.

In an increasingly digital world, establishing secure and reliable methods for verifying identity has become a critical priority across sectors such as finance, healthcare, education, and e-governance. Traditional authentication mechanisms—relying on passwords, personal identification numbers, and physical documents—are increasingly susceptible to fraud, data breaches, and user inconvenience. This paper presents a multi-modal biometric framework for digital identity management, integrating facial recognition and fingerprint verification to enhance accuracy, reduce fraud, and ensure user-centric security. The proposed system includes modules for data acquisition, preprocessing, feature extraction using Convolutional Neural Networks (CNNs) and minutiae detection, score-level fusion, and final authentication decisions. Security and privacy are ensured through AES-256 encryption, differential privacy techniques, and decentralized blockchain-based data storage. This research contributes a scalable, privacy-aware, and highly accurate digital identity model capable of addressing challenges such as interoperability, user trust, and regulatory compliance. Future enhancements include the integration of additional biometric modalities and deployment in mobile and IoT environments.

The exponential growth of the Internet of Things (IoT) necessitates robust, scalable, and secure identity management solutions to handle the vast number of interconnected devices. Traditional centralized identity systems are increasingly inadequate due to their vulnerabilities, such as single points of failure, scalability issues, and limited user control over data. This study explores a decentralized identity management model leveraging the IOTA Tangle, a Directed Acyclic Graph (DAG)-based distributed ledger technology, to address these challenges. By integrating Decentralized Identifiers (DIDs), Verifiable Credentials (VCs), and IOTA-specific technologies like IOTA Identity, IOTA Streams, and IOTA Stronghold, we propose a proof-of-concept framework that enhances security, scalability, and privacy in IoT ecosystems. Our implementation on resource-constrained IoT devices demonstrates the feasibility of this approach, highlighting significant improvements in transaction efficiency, real-time data exchange, and cryptographic key management. Furthermore, this research aligns with Web 3.0 principles, emphasizing decentralization, user autonomy, and data sovereignty. The findings suggest that IOTA-based solutions can effectively advance secure and user-centric identity management in IoT, paving the way for broader applications in various domains, including smart cities and healthcare.

Introduction: The Identity of a user in digital world is an important factor for an individual. Identity management has been handled by various models which, over the period of time have been prone various security breaches. The foremost integral part of any identity model is the centralized storage, access of data. Considering this, in recent years, there has been evolution from centralization to de-centralization of Identity management. With respect to this new aspect, this paper proposes a solution to the centralized management problems, as a decentralized Identity Management System. The said approach utilizes Ethereum blockchain, IPFS, both supporting distributed data accessibility and data storage respectively. This paper also sheds light on the W3C specification of DID (De-centralized Identifier) which supports the Self-Sovereign Identity principles of Identity Management and are vital for de-centralization of Identity Management

The research presents a blockchain-based identity management system for protecting decentralized web applications by operating through decentralized processes. Through its permissioned Ethereum network The-system enables automatic operations for identity lifecycle management to register authenticate authorize and revoke users while maintaining privacy of user data (anonymization and encryption of user data). Users receive hashed credentials which the blockchain ledger retains forever as secure storage alongside complete PII data privacy. Smart contracts determine access through comparison between incoming requests and permanent role statements stored on the blockchain network. Large attribute storage operates by connecting to Inter Planetary File System (IPFS) gateway servers that store blockchain reference data through content hash keys. Users accomplish authentication via a zero-knowledge proof module which enables attribute disclosure under zk‑SNARK’s parameters to reduce identity exposure. The consensus model deployed in the system supports execution of more than 5000 TPS transactions by completing them within sub-second periods. Performance evaluation confirms scalability, reliability, and real-time access control, demonstrating its viability for modern web applications requiring high throughput and low-latency operations. Security testing establishes that the network withstands Sybil attacks together with replay and man-in-the-middle attacks and privacy evaluation demonstrates unauthorized entities have no ability to derive user profiles. The evaluated benchmark results demonstrate that the framework's performance potential by testing 50 nodes in a test network locally. Research indicates that blockchain identity management develops an resistant system which has enormous potential capacity alongside privacy protection capabilities superior to conventional centralized identity management systems.

<em>This paper investigates decentralized trust management as a foundational element of Web 3.0, emphasizing a secure, autonomous, and user-driven approach to online interactions without reliance on centralized authorities. We address key challenges in decentralized environments, including those in Decentralized Finance (DeFi), decentralized identity (DID) systems, and Web 3.0 governance models. Our proposed framework integrates blockchain, Proof of Stake (PoS) consensus, Decentralized Identifiers, Zero-Knowledge Proofs (ZKPs), and smart contracts to create a comprehensive, secure, and scalable trust management solution. This method addresses limitations observed in traditional frameworks like X.509 and PGP, which only cover isolated aspects of trust. The results from our approach demonstrate considerable improvements in transaction security, user privacy, and data autonomy, driven by enhanced policy formulation and validation mechanisms. Through a robust trust scoring system and self-executing smart contracts, our solution ensures effective and transparent trust management across diverse Web 3.0 applications. Experimental results indicate that our integrated approach significantly elevates security and efficiency, positioning it as a scalable model for the evolving needs of decentralized networks. This work provides a solid foundation for future Web 3.0 systems, offering a practical and resilient framework for managing trust in decentralized, user-centric ecosystems</em><em>.</em>

Victory of digital services has produced new problems for identity management and security systems operating within online networks. The authentication systems that operate from central locations have become more susceptible to privacy breaches in addition to experiencing rising data security risks. This research develops a new identity access management solution which integrates AI alongside Blockchain and DIDs alongside SSI technology to enhance user-controlled security elements. AMD-SSI technology unions enable end-users to govern their digital personae independently from any control efforts from centralizing entities. Through Blockchain implementation users can attain both security and transparency while DIDs and SSI enable them to securely control their authentication methods. The document examines how to build and implement such a decentralized IAM framework and investigates its operational benefits and possible implementation hurdles to guide digital authentication practices.

Full textAbstract:
An Identity Management System (IDMS) is responsible for managing and organizing identities and credentials exchanged between users, Identity Providers (IDPs), and Service Providers (SPs). The primary goal of IDMS is to ensure the confidentiality and privacy of users’ personal data. Traditional IDMS relies on a third party to store user information and authenticate the user. However, this approach poses threats to user privacy and increases the risk of single point of failure (SPOF), user tracking, and data unavailability. In contrast, decentralized IDMSs that use blockchain technology offer potential solutions to these issues as they offer powerful features including immutability, transparency, anonymity, and decentralization. Despite its advantages, blockchain technology also suffers from limitations related to performance, third-party control, weak authentication, and data leakages. Furthermore, some blockchain-based IDMSs still exhibit centralization issues, which can compromise user privacy and create SPOF risks. This study proposes a decentralized IDMS that leverages blockchain and smart contract technologies to address the shortcomings of traditional IDMSs. The proposed system also utilizes the Interplanetary file system (IPFS) to enhance the scalability and performance by reducing the on-chain storage load. Additionally, the proposed IDMS employs the Elliptic Curve Integrated Encryption Scheme (ECIES) to provide an extra layer of security to protect users’ sensitive information while improving the performance of the systems’ transactions. Security analysis and experimental results demonstrated that the proposed IDMS offers significant security and performance advantages compared to its counterparts.

Full textAbstract:
Secure identity management is one of the controversial topics in the cybersecurity landscape. The user needs to rely on third-party providers for managing their personal information, which is a big security concern. Traditional identity systems typically suffer from single points of failure, lack of interoperability, and privacy issues such as encouraging mass data collection and user tracking. Blockchain technology has the potential to support novel data ownership and governance models with built-in control and consent mechanisms, which may benefit both users and businesses by alleviating these concerns. Blockchain-based systems provide the possibility for their users to insert their data in this distributed ledger. Users can trust the blockchain as it is leveraging consensus mechanisms to validate and gather the transactions in immutable blocks. The transparent and decentralized nature of the blockchain network enables the development of a non-refutable and unbreakable record of data, which is the fundamental feature of many applications, such as identity management.

Full textAbstract:
Federated Identity Management (FIM) has gained significant adoption as a means to simplify user authentication and service authorization across diverse domains. It serves as a centralized authentication and authorization method, enabling users to access various applications or resources using credentials issued by a universally trusted identity provider (IdP). However, recent security incidents indicate that the reliability of credentials issued by IdP is not absolute in practice. If the IdP fails, it can persistently access any application that trusts it as any user. This poses a significant security threat to the entire system. Furthermore, with the increasing adoption of FIM across diverse scenarios, there is a growing demand for the development of an identity management system that can effectively support digital forensics investigations into malicious user behavior. In this work, we introduce transparency to federated identity management, proposing T-FIM to supervise unconditional trust. T-FIM employs privacy-preserving logs to record all IdP-issued tokens, ensuring that only the true owner can access the exact token. We utilize identity-based encryption (IBE), but not just as a black box, encrypting tokens before they are publicly recorded. In addition, we propose a decentralized private key generator (DPKG) to provide IBE private keys for users, avoiding the introduction of a new centralized trust node. T-FIM also presents a novel approach to digital forensics that enables forensic investigators to collect evidence in a privacy-preserving manner with the cooperation of the DPKG. We conduct a comprehensive analysis of the correctness, security, and privacy aspects of T-FIM. To demonstrate the practical feasibility of T-FIM, we evaluated the additional overhead through experimental evaluations. Additionally, we compared its performance with other similar schemes to provide a comprehensive understanding of its capabilities and advantages.

Full textAbstract:
Identity management (IdM) is a method used to determine user identities. The centralized aspect of IdM introduces a serious concern with the growing value of personal information, as well as with the General Data Protection Regulation (GDPR). The problem with currently-deployed systems and their dominating approach, with identity providers (IdP) and single-point services, is that a third party is in charge of maintaining and controlling the personal data. The main challenge to manage data securely lies in trusting humans and institutes who are responsible for controlling the entire activity. Identities are not owned by the rightful owners or the user him/herself, but by the mentioned providers. With the rise of blockchain technology, self-sovereign identities are in place utilizing decentralization; unfortunately, the flaws still exist. In this research, we propose DNS-IdM, a smart contract-based identity management system that enables users to maintain their identities associated with certain attributes, accomplishing the self-sovereign concept. DNS-IdM has promising outcomes in terms of security and privacy. Due to the decentralized nature, DNS-IdM is able to avoid not only the conventional security threats, but also the limitations of the current decentralized identity management systems.

Full textAbstract:
Federated Identity Management (FIM) emerges as a critical solution for organizations navigating the complexities of modern digital environments, where identity management across disparate systems presents significant security challenges. By establishing trust relationships between identity providers and service providers, FIM enables seamless authentication across organizational boundaries while maintaining robust security controls. This comprehensive framework eliminates redundant authentication processes, reduces credential proliferation, and addresses the fragmentation issues inherent in multi-cloud environments. The architecture encompasses identity providers, service providers, trust frameworks, and claims mechanisms working in concert through standardized protocols such as OAuth 2.0, OpenID Connect, SAML, and WS-Federation. FIM delivers transformative benefits including enhanced user experience through Single Sign-On capabilities, strengthened security posture via centralized authentication, and substantial operational efficiencies. While implementation considerations such as just-in-time provisioning, attribute mapping, session management, and trust chain security present notable challenges, various architectural patterns including hub-and-spoke, mesh federation, and broker models offer flexible deployment options to match organizational requirements. As digital transformation accelerates, emerging trends such as decentralized identity, continuous authentication, and Zero Trust integration are reshaping the federation landscape.

As an individual, in the social and digital world, the burden of managing multiple online IDs and passwords, while handling a host of documents e.g passports, driver’s licenses, Social Security/Aadhar cards and medical insurance cards is cumbersome. Identities both in the social and digital world requires security and privacy: managing these identities efficiently is called Identity Management. Once these identities established, they are produced, shown, send, verified in some way or the other for various processes in Government and non Government purposes. Lately it is established that Blockchain technology has immense use to control over identities (Identity Management) with complete secrecy and privacy. Self-sovereign identity (SSI) is undergoing a transformative evolution, driven by the integration of blockchain technology and Facial Recognition Technology (FRT). This envisioned future entails a paradigm shift where unique facial features serve as the secure key for unlocking one's identity. Blockchain, functioning as a decentralized and secure repository, facilitates the storage of facial data. This convergence of SSI, blockchain, and FRT not only augments security but also streamlines authentication processes, reducing the reliance on conventional passwords and identification documents. It’s a future where individuals can seamlessly access their data, marking a significant advancement in secure and personalized identity management within an academic context.

Identity Management has turned into an imperative theme in the distributed computing conditions, where cloud suppliers need to control usernames, passwords and other data used to recognize, validate and approve clients for some, unique facilitated applications. Every one of the vulnerabilities seen on non-cloud arrangements are presently found in the cloud, yet different issues are presented. One would be the capacity to oversee characters of clients when sending information to the cloud .Second would be the identity administration of clients accepting information from the cloud. Furthermore, third would be administration of user id’s when information is moved from cloud to cloud. Open ID is an open standard and decentralized confirmation protocol. Promoted by the non-benefit Open ID Foundation, it enables clients to be verified by co-working locales (known as Relying Parties or RP) utilizing an outsider administration, taking out the requirement for website admin to give their own particular specially appointed login frameworks, and enabling clients to sign into numerous inconsequential sites without having a different personality and secret key for each.
