User Agent
From MgmtWiki
Full Title or Meme
An Entity that is operating at the consent and authority of the user.
Context
When discussing the use of the internet by a user, what is really meant is the presence of the user's agent on an internet connection.
Problems
Nearly any application running on a user's device is allowed to access the internet and claim that it represents the user. There is no build-in mechanism to test this assertion by an internet connected service.
