Authentication vs. Authorization

  • Definitions
    • Authentication is any process by which a system verifies the identity of a user who wishes to access it [http://mtechit.com/concepts/authentication.html]
    • Authorization is the process of giving someone permission to do or have something [http://hitachi-id.com/concepts/authorization.html]
  • Security is an important concern over mobile connections where devices are used in more open environments
  • Usual desktop solutions for authentication and authorization that requires complex interaction with remote services may constitute a complex overhead to mobile users
  • Thus we need to adopt principles to simply, but still retain security of access to remote services through mobile devices
    • Authentication from the API provider based on API Key stored on the devices can avoid user to provide their authorization details.
