(An alternate of e-voting): Mobile technology has attained heights and
the market trend is that every citizens of India will possess a mobile handset
by the year 2010 (at cheaper rates of service.) When such a PDA is available why
not using it for a time saving, cost effective, secured method of voting.
The concept is as follows:
¢ Every citizen
above the age of 18 years has got the right to vote and hence obtaining their
fingerprints and storing in the database along with their birth/death record becomes
necessary. ¢ User sends his finger print (secured print is encrypted
and sent as sequence of data in encoded form) to the service provider. ¢
Service provider verifies the fingerprint and checks for the validity of voting
and sends voter list (a mobile ballot paper) through SMS. ¢ User casts
his vote and sends 2nd message.
mobile phone has connectivity with computer systems it is easy to store and access
at the service provider and results be published instantly.
print sensor: The FingerLoc sensor is a monolithic silicon chip comprising
a sensing array and its associated circuitry, all covered by a fairly thick (75
micro metre) proprietary coating. It can be easily embedded in the surface of
a cell phone, where the robust coating will protect it from the rigors of normal
usage. FingerLoc' key advantage over other (optical) fingerprint sensors, is that
it ignores the external fingerprint in a buried layer of living cells, where fingerprints
are created, and where they are found in pristine condition.
it does is apply a low-voltage ac signal to the fingertip and then measure how
the resulting electric field varies in amplitude over the fingertip surface.The
signal is applied by means of a conductive epoxy ring surrounding the sensor area.
It is defined and measured with respect to a reference plane within the chip.The
electric field is set up between the reference plane and a thin layer of highly
conductive saline liquid that resides at the interface of the living skin tissue
and the dead skin. The saline layer has same shape as the living tissue- the shape
of the fingerprint. Being highly conductive, it imposes its shape as a boundary
condition on the field, thereby spatially modulating the field into an analog
of the fingerprint.
An array of tiny antenna
arranged in a square matrix of 96 rows and columns does the actual sensing. Located
above the reference plane, the array measures about 6.5mm on a side, giving the
sensor a linear resolution of about 15 pixels per millimeter.The sensed analog
electric field values are scanned from the sensor matrix a row at a time, digitized,
and sent from the FingerLoc chip to the cell phone's microprocessor for further
processing.In the cell phone, a module from a special software suite analyzes
the fingerprint pattern and extracts information from it, which it converts into
a unique representation of the fingerprint owner's. To register a voter, that
representation, called a template, is stored in nonvolatile memory and in storage
of Service Provider for instance VSNL for future use.
happens next depends on how the cell phone manufacturer and service provider have
set things up. If the handset does not recognize the applicant, service will be
denied. It gets more interesting when the system does recognize the fingerprint,
because each user can have a stored profile, which personalizes the phone for
him or her.
