The Election Service checks e-voting. They ensure that all data is correct. The Election Service conducts an audit for every election. The auditor checks whether the votes are correct.
Scientist Tarvo Treier studied the system. He introduced errors into the e-voting boxes for testing. Auditors found only 5 errors. For example, an error where a "ghost vote" was added was not detected.
Treier said that his work does not mean that e-voting is dangerous. He simply showed how auditing can be improved.
The Election Service states that e-voting is secure. E-voting has been in use for 20 years. The Election Service is working on new software. This will make auditing easier. The new system may come into use in the next elections.
