Electoral Integrity System (SIE)
Electoral Service of Chile (SERVEL)
The SIE is an independent, parallel system that counts and publishes Chile's election results alongside SERVEL's official system, acting as a real-time backup and verification layer.
Context
Chile's Electoral Service (SERVEL) awarded the Electoral Integrity System (SIE) to EVoting through a public tender: an independent system that counts the same tally sheets as the official system, but on its own, as a backup and cross-check. A third system automatically compares both counts; if they match, results are published — so the country never depends on a single system to trust its results.
Challenge
Verifying 100% of the country's polling stations in real time —not a sample— means processing and validating every tally sheet as it arrives, over the course of a single election night, for a roll of more than 15 million voters and peaks of up to 50,000 simultaneous users checking results.
Solution
The SIE receives and validates every digitised tally sheet, processes results by applying each election's rules, and publishes turnout, polling-station progress and results by territory, updated every 15 minutes, for SERVEL, the press and the public. Ahead of each election, the system goes through load tests at 10% and 100% of the country's scale (45, 30 and 15 days out), and on the eve of election day it is sealed and frozen to verify nothing has been altered.
Results
The SIE has been used in 5 consecutive elections alongside SERVEL, verifying 100% of the country's polling stations in real time over a roll of more than 15 million voters, with peaks of up to 50,000 simultaneous users at the moment of highest demand.
“Contributing directly with our experience and knowledge to a national electoral process makes us feel very proud. We hope to continue along this path and be able to help even more in the future.”
