Yes, the secrecy of the ballot is protected in online elections with POLYAS.
After logging into the online voting system with POLYAS CORE 2.2.3., an anonymous token is generated for you. This token does not allow to deduce any information concerning your identity. After casting your vote using this token, your token will be deleted and the electoral roll will be notified that no new token can be generated for this access data.
That is how the electoral roll knows that you took part in the election without knowing how you voted. The digital ballot box knows that the ballot has been filled out but cannot know who filled it out. The only person who knows how you voted is you, ensuring the secrecy of the ballot is maintained.
After casting a vote, it is impossible to determine who individuals have voted for in the election: the voter’s personal data is completely anonymous and separated from the ballot, so it would be impossible to determine how voters have cast their vote.
POLYAS CORE 3.0 guarantees the secrecy of the ballot through asymmetrical encryption methods: Voters’ identity is anonymized when voting online and separated from the voting process, so that there would be no access to information concerning voters’ identity.
This is how the secrecy of your ballot is maintained using POLYAS CORE system and according to the main election principles.
