Abstract
Securing data acquired by coordinate measurement devices including receiving a request from a requestor to access a data file including data that was acquired by a coordinate measurement device. The data file is retrieved and the content of the data file is authenticated. The authenticating includes retrieving an expected digital security attribute previously calculated by a digital security function based on content of the data file prior to the data file being retrieved. The authenticating also includes applying the digital security function to the data file to calculate an actual digital security attribute, and comparing the expected digital security attribute to the actual digital security attribute. Based on the comparing, a value of valid or not valid is assigned to an output of the authenticating.
