<p>A system with methods and apparatus for authenticating measurements that resist human errors and attempts to render or present fraudulent measurements. A system obtains a measurement 22,82 and substantially contemporaneously determines a set of one or more space/time parameters for the measurement 22,82. The system includes methods and apparatus for generating a certificate in response to the measurement 22,82 and the space/time parameters such that the certificate enables a determination of whether a set of alleged data is the measurement 22, 82. obtained according to the space/time parameters. <IMAGE></p> |
