Title: Providing For Data Security In The
GIS
Applications For Public Safety
Abstract: GIS systems are used in wide range
of
applications of sensitive nature, this paper intends to concentrate on
emergency
contingency planning and emergency response management applications of
GIS
from the point of view of providing the necessary data security in
providing
public safety and homeland security. These applications necessitate the
use
of secured communications and networking. Geographic data
sets
occupy large memory space and most of them are in public domain, it is
considered
that only the data representing locational intelligence specific to the
application
need to be kept secure data. Multi-user GIS implementations are based
on
n-tier client-server architecture, the data transmissions in question
would
be between the server and the clients, some of the clients might be
remote
and/ or mobile clients. In order to provide data secrecy and
authenticity
the cryptographic technique PKI (Public Key Infrastructure) application
is
proposed as a solution. The 8-steps security protocol explained in this
paper
can be used to provide a high-level of data security avoiding
overloading
the network as much as possible. PKI Protocol would secure
the
communication channels as well as introduce the tools for
authentication.
The advantages and limitation of the proposed protocol is reported.
