A method for detecting ANY unauthorized alteration, tampering, etc. of a
mobile entity seeking to gain access to a secure facility, thus
protecting the facility against threats. This approach broadens
typical single identity verification to simultaneous, multiple
identity verifications associated with a mobile entity system
greatly increasing the likelihood that any tampering will be
detected if any identity element reflects a change.
Before a mobile entity begins a trip, a PLURALITY of identities
related to the mobile entity system are selected as requiring
verifications. Discrete identity elements can include: the
vehicle computer's signature, other On-Board Identity (OBI) devices (e.g., Easy
Pass transponder, GPS signature); vehicle discrete Characteristics
Identity (CI) elements, driver carried authorization, driver's retina or
print confirmation, voice recognition and/or responses to a
variable question array, cargo embedded OBI devices, et al.
Once verification elements are selected, initial identifying
information is collected by a Security Management System (SMS) and a
Composite On-Board Identity (COBI) is SMS defined for the mobile
entity system. The COBI can be a SMS randomly encoded Master Number
(MN) which identifies the mobile entity to a verification authority
or SMS checks at the destination as well as at en route checkpoints.
Route and schedule information may also be SMS recorded for en route
pass point schedule monitoring.
Some OBI signatures making up the COBI may be selectively disabled
for security by the SMS during travels then reactivated at the destination to
confirm integrity of each identity element in the mobile entity
system. The identifying mechanisms are thereby further protected
against intrusion or hacking while the mobile entity is en route.
If en route verifications fails or tampering is sensed by the
onboard MN controller, this device can prevent further vehicle
operation until the failure cause is resolved. At the
destination, the SMS
reads the on-board MN and then confirms the integrity of each OBI.
