Abstract: This paper presents an authentication method with different authentication levels. This system is different from other multi-factor authentication methods in that it enhances the levels with an access control. The access control contains attributes of the most authenticated user assigned in structured mode. Each sent message must classify according to its global context. The manager of the system takes this global context and submits it to a context analyser whose responsibility is to deduce lower levels of that global context. Then the manager forwards it to the suitable authenticated user in selected lower levels of the multi-factor scheme.
