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.
