UML interaction overview diagram - System authentication

"Authentication ... is the act of confirming the truth of an attribute of a single piece of data (datum) or entity. In contrast with Identification which refers to the act of stating or otherwise indicating a claim purportedly attesting to a person or thing's identity, Authentication is the process of actually confirming that identity. It might involve confirming the identity of a person by validating their identity documents, verifying the validity of a website with a digital certificate, tracing the age of an artifact by carbon dating, or ensuring that a product is what its packaging and labeling claim to be. In other words, Authentication often involves verifying the validity of at least one form of identification." [Authentication. Wikipedia] The UML interaction overview diagram example "System authentication" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Rapid UML solution from the Software Development area of ConceptDraw Solution Park.
