Digital Value Imprinted Instruments (DVIIS) is a patent
pending invention of Na.Vijayashankar having
wide application in several areas of E-Governance. The utility of DVIIS
for certain E-Governance applications for which Smart Cards are used and
its cost effectiveness is explained in this brief note. DVIIS is available
for implementation within a short notice and Naavi is also open to IT
Companies to work as implementation partners for delivering the solutions.
Limitations of Smart
Smart Cards are popular
instruments in many applications involving authentication and reference to
information related to the Smart Card owner.
The cost of using Smart
Cards for different solutions is directly related to the memory capacity
of the embedded chip.
Presently, one of the
areas in E-Governance where Smart Cards are being used successfully is for
RC book and Driver’s License.
The limitations of the
smart cards are the memory capacity of the embedded chip and the need for
a smart card reader at the usage point. The smart card based system can
work efficiently in an environment where the access is limited to certain
designated offices. If however the system is to be accessed at filed level
by a large number of people, the cost of providing smart card readers
becomes uneconomically high.
Secondly, many of the smart card applications are limited to
accessing static data and does not involve processing as in the case of
say a debit card used in an ATM where the data has to be dynamically
altered at the usage point. In such cases also the use of Smart Cards is
an over use of technology and therefore uneconomical.
Thirdly, at one point of
time, Smart Cards were considered very secure but this has been proved to
be untrue since hackers have found a way of breaking into Smart cards
Considering all these
aspects, when Smart cards are used for very large requirements such as the
Citizen’s ID card, the wastage factor in the overuse of technology becomes
a national concern.
We need to therefore
look for alternatives where “Appropriate Technology” is used for building
cost effective solutions to replace Smart Cards where feasible. DVIIS
is one such alternative.
DVIIS Solution in
DVIIS is based on the
principle of an “I-Card” in the physical world which is a low cost paper
based card which can be used as an Identity card with intelligent hook up
to a master database. The I-Card itself can be developed on different
security levels including a bar code mechanism even though this is also
redundant in most cases.
The I-Card is linked to
the master data base through an identity embedded in the physical
instrument. The data however is stored on a server which is accessible
both through an Internet access device as well as a telephone device.
The telephone device
which is the most widely available low cost access device is sufficient to
extract information from the database through a voice recognition system.
Printer attachments to the telephone device can also be worked out where
required though in some applications, use of pre-printed stationery
obviates the need to use a printer device at the user’s end.
Where the access is
through Internet, the data can be processed under appropriate
authentication so that all the functions that a Smart Card can achieve can
be achieved without a special smart card reader at the user’s end, and
without any limitation on the memory or processing capacity of the chip.
Thus if the R.C. records
of vehicles or Driver’s license records are contained in a centralized
database, any Policeman on the street can invoke the system through the ID
contained on the DVIIS card and listen the details being read out to him.
The access is through a normal telephone or a mobile.
The user’s cards cost
less than a rupee to produce and can be replaced as often as required.
The cost of the total system is therefore a fraction of the
smart card system and is more versatile. It can be used in any remote
place accessible by telephone.
All the systems support
“Pay as you Use” principle and hence the capital cost of introducing the
system is minimal for any Government.
The security concerns are
related to the maintenance of a secure server accessible on the Internet
and not different from the systems that control Banking transactions and
Payment Gateways. Hence the risks inherent in such systems are manageable.
Apart from the
applications described above for RC Book and Driver’s license, the DVIIS
is a system that can be used for “Digital Stamps”, “Collection of Road
tax” and “Collection of Utility Payments”.
The system can be
elaborated with reference to individual applications on request by Naavi
