An electronic voting method, system and apparatus is disclosed. A vote message is received at a network node, the vote message comprising a sender identifier, event identifier and a timestamp. The sender identifier, event identifier and timestamp are read, and it is determined from the timestamp that an event window was open and whether the window was a first or subsequent window. In the event that the window is the first window, the vote and sender identifier are stored at a database. In the event that the window is a second or subsequent window, the sender identifier is compared to sender identifiers stored at a previous window and if a match is found the vote is marked as validated and the vote stored at the database.
