1. A method of verifying data integrity comprising the steps of:
- a) sensing a condition indicative of faulty data acquisition integrity collected by a device, wherein at least one of the sensed conditions includes detecting an absence of power from a main power source to the device;
b) obtaining data indicative of movement of the device during the detected absence of main power by powering at least one sensing device powered by a back-up power source disposed within the device;
c) storing data indicative of the sensed condition as an encoded entry;
d) forwarding the encoded entry with other acquired data to a central processor;
e) evaluating the encoded entry against predetermined criteria; and
f) indicating that data integrity has been compromised responsive to a failure of the encoded entry to fall within the predetermined criteria.

Abstract
This invention is a system and process for determining and verifying the voracity of data gathered for use in recording and tracking vehicle usage. The device operates to verify and detect events that may affect data integrity by sensing a condition indicative of faulty data acquisition or of corruption of data integrity. Data evidencing potential problems are encoded and included with normal data uploaded to a central server. The central server compares the encoded entries against criteria that have been determined to indicate potential data inconsistencies.

13. A device for acquiring data indicative of vehicle usage comprising:
-
a power module including a connection to an external power source, and an internal power source for powering said device independent of the external power source; a first sensor for detecting motion of said device; a data storage medium for storing data indicative of vehicle usage; and a controller programmed to collect data from said first sensor responsive to the power module not receiving power from the external power source. - View Dependent Claims (14, 15, 16, 17, 18)
