Because the document did not have a single over-arching structure, many concepts were dealt with in a somewhat piecemeal fashion. Different aspects of the same concept appeared in various parts of the document. Grouping these aspects together should help prevent inconsistencies.
In our restructured set we included:
5) ``An authentication system shall exist to distinguish eligible voters from others, and those who have successfully cast votes from those who have not. Note: this may require special attention where multiple voting channels exist, and where voter registers may not be up-to-date.''
This incorporates the following five standards from the original document:
(5b) ``A voter shall be authorised to vote only if it has been established that his/her ballot has not yet been inserted into the ballot box.''
(6) ``The e-voting system shall prevent any voter from casting a vote by more than one voting channel.''
(41) ``In cases where there is an overlap between the period for voter registration and the voting period, provision for appropriate voter authentication shall be made.''
(44) ``It is particularly important, where remote e-voting takes place while polling stations are open, that the system shall be so designed that it prevents any voter from voting more than once.''
(82) ``Identification of voters and candidates in a way that they can unmistakably be distinguished from other persons (unique identification) shall be ensured.''
