A public key infrastructure (PKI) is a set of roles, policies, hardware, software and procedures needed to create, manage, distribute, use, store and revoke digital certificates and manage public-key encryption.
Identity and access management, sometimes also referred to as just Identity management (IdM), is a framework of policies and technologies to ensure that the right users have the appropriate access to technology resources. IAM systems fall under the overarching umbrellas of IT security and data management. Identity and access management systems not only identify, authenticate, and control access for individuals who will be utilizing IT resources but also the hardware and applications employees need to access.
The Liberty Alliance Project was an organization formed in September 2001 to establish standards, guidelines and best practices for identity management in computer systems. It grew to more than 150 organizations, including technology vendors, consumer-facing companies, educational organizations and governments. It released frameworks for federation, identity assurance, an Identity Governance Framework, and Identity Web Services.
A federated identity in information technology is the means of linking a person's electronic identity and attributes, stored across multiple distinct identity management systems.
A digital identity is data stored on computer systems relating to an individual, organization, application, or device. For individuals, it involves the collection of personal data that is essential for facilitating automated access to digital services, confirming one's identity on the internet, and allowing digital systems to manage interactions between different parties. It is a component of a person's social identity in the digital realm, often referred to as their online identity.
OpenID is an open standard and decentralized authentication protocol promoted by the non-profit OpenID Foundation. It allows users to be authenticated by co-operating sites using a third-party identity provider (IDP) service, eliminating the need for webmasters to provide their own ad hoc login systems, and allowing users to log in to multiple unrelated websites without having to have a separate identity and password for each. Users create accounts by selecting an OpenID identity provider, and then use those accounts to sign on to any website that accepts OpenID authentication. Several large organizations either issue or accept OpenIDs on their websites.
A mobile signature is a digital signature generated either on a mobile phone or on a SIM card on a mobile phone.
Electronic authentication is the process of establishing confidence in user identities electronically presented to an information system. Digital authentication, or e-authentication, may be used synonymously when referring to the authentication process that confirms or certifies a person's identity and works. When used in conjunction with an electronic signature, it can provide evidence of whether data received has been tampered with after being signed by its original sender. Electronic authentication can reduce the risk of fraud and identity theft by verifying that a person is who they say they are when performing transactions online.
Privacy-enhancing technologies (PET) are technologies that embody fundamental data protection principles by minimizing personal data use, maximizing data security, and empowering individuals. PETs allow online users to protect the privacy of their personally identifiable information (PII), which is often provided to and handled by services or applications. PETs use techniques to minimize an information system's possession of personal data without losing functionality. Generally speaking, PETs can be categorized as either hard or soft privacy technologies.
Identity assurance in the context of federated identity management is the ability for a party to determine, with some level of certainty, that an electronic credential representing an entity with which it interacts to effect a transaction, can be trusted to actually belong to the entity.
The National Strategy for Trusted Identities in Cyberspace (NSTIC) is a US government initiative announced in April 2011 to improve the privacy, security and convenience of sensitive online transactions through collaborative efforts with the private sector, advocacy groups, government agencies, and other organizations.
Kantara Initiative, Inc. is a non-profit trade association that works to develop standards for identity and personal data management. It focuses on improving the trustworthy use of identity and personal data in digital identity management and data privacy.
The Government Digital Service is a unit of the Government of the United Kingdom's Department for Science, Innovation and Technology, tasked with transforming the provision of online public services.
ID.me is an American online identity network company that allows people to provide proof of their legal identity online. ID.me digital credentials can be used to access government services, healthcare logins, or discounts from retailers. The company is based in McLean, Virginia.
A trust service provider (TSP) is a person or legal entity providing and preserving digital certificates to create and validate electronic signatures and to authenticate their signatories as well as websites in general. Trust service providers are qualified certificate authorities required in the European Union and in Switzerland in the context of regulated electronic signing procedures.
Digital identity is used in Australia by residents to validate who they are over digital media, such as over the Internet.
GOV.UK Verify was an identity assurance system developed by the British Government Digital Service (GDS) which was in operation between May 2016 and April 2023. The system was intended to provide a single trusted login across all British government digital services, verifying the user's identity in 15 minutes. It allowed users to choose one of several companies to verify their identity to a standard level of assurance before accessing 22 central government online services.
The once-only principle is an e-government concept that aims to ensure that citizens, institutions, and companies only have to provide certain standard information to the authorities and administrations once. By incorporating data protection regulations and the explicit consent of the users, the public administration is allowed to re-use and exchange the data with each other. The once-only principle is part of the European Union's (EU) plans to further develop the Digital Single Market by reducing the administrative burden on citizens and businesses.
Self-sovereign identity (SSI) is an approach to digital identity that gives individuals control over the information they use to prove who they are to websites, services, and applications across the web. Without SSI, individuals with persistent accounts (identities) across the internet must rely on a number of large identity providers, such as Facebook and Google, that have control of the information associated with their identity. If a user chooses not to use a large identity provider, then they have to create new accounts with each service provider, which fragments their web experiences. Self-sovereign identity offers a way to avoid these two undesirable alternatives. In a self-sovereign identity system, the user accesses services in a streamlined and secure manner, while maintaining control over the information associated with their identity.
Many nations have implemented, are implementing, or have proposed nationwide digital identity systems.
