Abstract
A measurement probe, such as a touch trigger measurement probe, is described that comprises a measurement portion for measuring an object and a data transfer portion for receiving data from and/or transmitting data to an associated unit. The measurement device also comprises an authentication module for verifying the authenticity of the associated unit. The authentication module may include a processor for running a one-way hash algorithm. Authenticity may be established using a challenge and response authentication process.

15. A measurement probe for co-ordinate positioning apparatus, the measurement probe comprising;
-
a measurement device for generating measurement data indicative of the position of at least one point on the surface of an object; a communications device for communicating with a remote probe interface; and an authentication device for determining if the remote probe interface is an authentic remote probe interface, wherein the communications device passes the measurement data to the remote probe interface only when the authentication device has determined that the remote probe interface is an authentic remote probe interface. - View Dependent Claims (16)
