Internal
Identity
The identity could be that of a human using the computer and running programs, or of a automation system. In the first case we qualify the identity as "user identity", and in the second case we use the terms "system account" or "service account" identity.
End User Identity
A human user.
Service Account Identity
System Account Identity
Authentication
Authentication is the process of identifying a subject and verifying the authenticity of the identification information.
The most common authentication mechanism is username/password. Other mechanisms are available: public key, shared key, smart cards, etc.
In the context of JEE declarative security, the result of a successful authentication is called a principal.
Related subjects: Basic and Digest HTTP Authentication.
Authorization
Authorization is the mechanism for granting or denying access to a resource based on identity.
In JEE, this is usually implemented by matching a principal with a set of actions they are or are not allowed to perform. This mapping is referred as a role.

To Process
Identity Federation and Single Sign-On are related concepts.
Single Sign-On (SSO) systems allow a single user authentication process across multiple IT systems and organizations. SSO is a subset of federated identity management, as it relates only to authentication and technical interoperability.
User's presence in the system - means that the user identity is associated with the thread that is processing the user's request, and in a way, it is the user that "drives" the thread. The identity is associated with the thread in the form of a security context.
Authentication. The whole point of an authentication protocol is to tell whether the user is present in the system.
Identity Provider (IdP) and Relying Party (RP).
Authentication protocols, single sign-on, SAML.
Authorization.
