M-Voting (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.

Since mobile phone has connectivity with computer systems it is easy to store and access at the service provider and results be published instantly.

Finger 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.

What 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.

What 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.
