Polling System Solution

Registration and Security
• The user receives three separate key-pairs at login. Each gives the user access to the service in
various ways.
• The sign in key-pair, for example, allows users future access to the platform, while the encryption
key-pair lets the user receive information and a final ethereum account key-pair lets the user
write smart contracts.
• The identity itself is then created by populating fields in an existing ethereum smart contract with
any number of attributes.
• Attributes could be a finger print, retina scan, a drivers license or a passport. Then, a hash of that
smart contract serves as the user's identification.
• Only on the match and validation of data hash the records would be committed.

States of Data and Security
• The data stored into the database will be
encrypted to avoid identity threats.
• System validates execution output and
changes will merged on commit.
• Delta hash must match to pass the
validation.
• A transaction's execution must first
achieve consensus that it belongs and
then be validated before its execution
transpires.

Integration of the protocol
• System will use biometrically secured multi-signature
transactions (Finger-print, Retina, Password, etc.).
• System will use multifactor wallet that requires two of
three keys for a transaction to take place.
• Each key is generated and stored in a different location
and is protected by a different authentication factor so
that there’s no single point of failure.
• Solution will be designed with protocol specific signed
Distributed Hash Table with the hash of the public key.
• OAuth will be used as one of the key authentication factor for
key authentication.
• 2 factor authentication will secure and make user friendly
authentication like mobile and email OR mobile / email based
OTP.

Transaction Security
• Blockchain adds a persistent code and security layer to the
process.
• Each service / user in the network has its own copy of the
blockchain attached to every asset.
• As long as the chains are in sync, all user / services can be
confident that the asset or transaction is valid.
• Each time the asset is modified, a new block is added, creating a
chain (hence the term).
• All parties in the network receive a copy of the updated asset with
the new blockchain.
• As long as the blockchains match, there can be no question about
authenticity.
• if any blockchain doesn’t match the others, the asset is considered
invalid and the update is rejected.
• Updates happen very quickly, usually in milliseconds.
• Each transaction is secured with the previous transaction’s hash
and the public key of the next owner are digitally signed with the
current owner’s private encryption key.
• Once an entry is written into the block chain, it cannot be altered
without regenerating the previous blocks.

Polling System
• User will get enrolled with the system using
blockchain.
• Enrolment will provide a token to validate and used for
authorize or authenticate the user for future.
• After enrolment for each transaction user will have a
unique key which allow user to make secure and
authenticated transaction.
• Electoral authority only will be able to see the voted
data not the transaction data but can verify.
• Voting Manager will manage the votes and allow only
authorized user to vote based on the configuration
defined by manager (i.e. Zonal voting, State Voting,
Society Voting, University Voting).
• Voting manager will make secure connection with
Voting Console which could be a device / web / mobile
platform and provide receipts on successful voting.

Delegation vote / Casting vote
• Voters to the left of the blue line voted by delegation.
• Voters to the right voted directly.
• Numbers are the quantity of voters represented by each delegate.
• The delegate included in the count.
• Solution also will work in same manner where each voter and
delegate will have its own enrolment certificate.
• System will define the role of delegate where delegate’s
transaction certificates will have included with a unique delegate
code.
• Each voter’s transaction will be associated with delegate’s
transaction on time of delegate voting.
• Transaction unique code will be stored in sequence in form of
chain so fault can be easily identified and prevented in case if any.
