Voting system, vote relay server, client terminal, voting method, advertisement distribution system, and program

A system for relaying votes, the system comprises:

• a processor;
• and
• a memory storing computer-executable instructions that when executed by the processor cause the system to:
• generate, by a server, a plurality of votes, wherein the plurality of votes includes secret information for distribution among a plurality of client terminals;
• transmit, by the server, a vote of the plurality of votes to a client terminal of the plurality of client terminals using an encrypted data communication, causing the client terminal to receive and encrypt the vote using at least a user key associated with the client terminal;
• receive, by the server, a plurality of encrypted votes, wherein the plurality of encrypted votes includes the encrypted vote by the terminal, and each encrypted vote of the plurality of encrypted votes is decryptable by the client terminal according to a predetermined condition;
• and
• transmit the plurality of encrypted votes to the client terminal, causing the client terminal to decrypt the plurality of the encrypted votes according to the predetermined condition and to determine a voting result based on a number of the plurality of votes.

A computer-readable non-transitory recording medium storing computer-executable instructions that when executed by a processor cause a computer system to:

• generate, by a server, a plurality of votes, wherein the plurality of votes includes secret information for distribution among a plurality of client terminals;
• transmit, by the server, a vote of the plurality of votes to a client terminal of the plurality of client terminals using an encrypted data communication, causing the client terminal to receive and encrypt the vote using at least a user key associated with the client terminal;
• receive, by the server, a plurality of encrypted votes, wherein the plurality of encrypted votes includes the encrypted vote by the client terminal, and each encrypted vote of the plurality of encrypted votes is decryptable by the client terminal according to a predetermined condition;
• and
• transmit the plurality of encrypted votes to the client terminal, causing the client terminal to decrypt the plurality of the encrypted votes according to the predetermined condition and to determine a voting result based on a number of the plurality of votes.
