Location-based authentication

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.


  • 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.[1]
  • Location-based authentication is a novel procedure to provide additional information about the authenticity of a product.[2]


As of 2008, 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
