Location based authentication is a special procedure to prove an individual's identity and authenticity on appearance simply by detecting its presence at a distinct location.

To enable location based authentication, a special combination of objects is required.

• Firsthand, the individual that applies for being identified and authenticated has to present a sign of identity.
• Secondly, the individual has to carry at least one human authentication factor that may be recognized on the distinct location.
• Thirdly, the distinct location must be equipped with a resident means that is capable to determine the coincidence of individual at this distinct location.

Distinctiveness of locating

Basic requirement for safe location based authentication is a well defined separation of locations as well as an equally well defined proximity of the applying individual to this location.

Applications

• Location based authentication is a standard procedure to grant access to an area by detecting a person at an entrance. Then of course a discrimination is recommended to recognise a person entering or leaving, just to prevent two persons gaining access on one ticket only.

• Location based authentication is a standard procedure to get access to a machine, especially a working position with a computer and the functions of this computer .

• Location based authentication is a novel procedure to provide additional information about the authenticity of a product .

Challenges

, no offered technical solution for simple location based authentication includes a method for limiting the granted access to the presence, hence terminating the granted authentication on leave. This defines a mandate either to include a new or an additional procedure for

• detecting the leave and closing the granted access,
• limiting the granted time for access
• combining the method with another specially suited authentication factor
