Identity Management System

This article describes how in today's digital world, customers have made it a common practice to maintain user accounts with different service providers to access a range of services. In such environment, all attributes of the identity must be verified to operate, otherwise the resources would be vulnerable to financial and data loss. This article contends that makes it important to form an Identity Management System, which could provide central administration, user self- service, role based access control and integrated user management. Identity Management becomes very much vital for the environment working with multiple technologies, as it governs an entity (i.e. a human or a software agent) to authenticate and authorize for accessing the network via multiple technologies. Successful Identity Management increases the efficiency, security, access control and decreases the complexity, cost and many repetitive works. Essential features of present day identity management systems have been identified in the present work. A comparative analysis of these identity management systems has been carried out to establish the present-day industry practices. Along with that, specific challenges to the present-day identity management systems have been identified. The article helps in the identification of suitable Identity Management System for specific applications.

Identity management is the administration of an individual's access rights and privileges in the form of authentication and authorization within or across systems and organizations. An Identity Management system (IdM) helps manage an individual's credentials through the establishment, maintenance, and eventual destruction of their digital identity. Numerous products, applications, and platforms exist to address the privacy requirements of individuals and organizations. This chapter highlights the importance of IdM systems in the highly vulnerable security scenario that we live in. It defines and elaborates on the attributes and requirements of an effective identity management system. The chapter helps in establishing an understanding of frameworks that IdM systems follow while helping the reader contrast between different IdM architecture models. The latter part of this chapter elaborates on some of today's most popular IdM solutions.

Set Up

Identity management systems in Internet belong to different circles of trust and it is difficult to set up trust relationship among Identity Providers (IdPs) or Service Providers (SPs) which are located in different circles of trust. This paper proposes a distributed trust federation framework to solve the problem and its efficiency is analyzed with several experiments. It uses IdPs which belong to multiple Circles of Trust (CoTs) as relay entities to set up trust relationship among CoTs. The proposed framework is effective to extend the trust federation of identity management systems and thus improve easy of use for users in Internet..

Identity Management System

Today, cloud-based services and applications are ubiquitous in many systems. The cloud provides undeniable potential benefits to the users by offering lower costs and simpler deployment. The users significantly reduce their system management responsibilities by outsourcing services to the cloud service providers. However, the management shift has posed significant security challenges to the cloud service providers. Security concerns are the main reasons that delay organizations from moving to the cloud. The security and efficiency of user identity management and access control in the cloud needs to be well addressed to realize the power of the cloud. In this chapter, the authors identify the key challenges and provide solutions to the authentication and identity management for secure cloud business and services. The authors first identify and discuss the challenges and requirements of the authentication and identity management system in the cloud. Several prevailing industry standards and protocols for authentication and access control in cloud environments are provided and discussed. The authors then present and discuss the latest advances in authentication and identity management in cloud, especially for mobile cloud computing and identity as a service. They further discuss how proximity-based access control can be applied for an effective and fine-grained data access control in the cloud.

An efficient identity management system has become one of the fundamental requirements for ensuring safe, secure, and transparent use of identifiable information and attributes. Federated Identity Management (FIdM) allows users to distribute their identity information across security domains which increases the portability of their digital identities, and it is considered a promising approach to facilitate secure resource sharing among collaborating participants in heterogeneous IT environments. However, it also raises new architectural challenges and significant security and privacy issues that need to be mitigated. In this paper, we provide a comparison between FIdM architectures, presented the limitations and risks in FIdM system, and discuss the results and proposed solutions.

Identity Management System

Techniques for authentication that are used in today's identity management systems are vulnerable when they are used over the network. In order to prevent fraud and unauthorized data access, it is important to ensure the identity of the person who submitted authentication credentials. The authentication process can be additionally secured by using biometric data for user verification. Moreover, precision of biometric authentication can be improved by the use of multimodal biometrics. This paper presents a system which has been designed for identity management based on FreeIPA solution for digital identity management and MMBio framework for multimodal biometrics. Proposed system provides multifactor authentication, where MMBio framework is used for handling user biometric data. Developed prototype confirms possible integration of identity management and multimodal biometric systems.

Ehealth Service

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.
