Evidence Collection from Car Black Boxes using Smartphones
[attachment=18747]
INTRODUCTION
Car black box is a device to record driving history which
can be used for car forensics in case of car accident or related
crimes. Car black box stores video clips that could be critical
clues for investigating car-related accidents or crimes. Those
video clips can be collected to police server via VANET
infrastructure that provides V2I or V2V connections. In many
cases without VANET infrastructure, 3G networks can be used
for transmitting video clip data. Especially, smart phones are
very useful for this purpose.
This demonstration shows the whole process to collect
video proofs using smart phones in VANET infra-less
environment. Some cryptographic mechanisms were used to
provide video integrity and privacy.
THE PROPOSED SCHEME
In this section, we make assumptions and describe our
proposed scheme in detail. Our scheme is proposed under the
following assumptions:
· Every car is equipped with smart phone, car black box,
and Global Positioning System (GPS).
· Car black box and smart phone can communicate with
each other in order to transmit data by using wireless
communication, e.g. Bluetooth. In addition, they share
a symmetric key in advance for mutual authentication.
· All of drivers use evidence collecting system and the
devices are always turn on when car moves. Each
smart phone is installed with special software which
we developed. Besides, in order to communicate with
police station server, a driver needs to have a user ID
and password which are already preset in smart phone.
CONCLUSION AND FUTURE WORK
In our demonstration, the evidence collecting system,
which uses smart phone not only to transmit critical videos to
the police station server, but also to manage information
obtained from car black box, was proposed. In fact, it is very
hard to fully deploy VANET infrastructure. As a result, even
though the communication between car black box and police
station server which use VANET infrastructure could be
possible, it is not easy to apply in practice. In addition, our
demonstration also shows how to apply security functions in
evidence collecting system. In our proposed scheme, therefore,
security services are guaranteed, e.g. access control and data
integrity.
