There are many places and Web pages that include votings. Some, like menéame.net, Blog memes or Populiicias, they use them as a support base; without them they would not be right of existing. sin ellas no tendrían razón de existir.
There are different the forms in which the script that controls the votings can identify the voter:
- For user's name: The voter has to identify with a name that previously it registered. The system prevents the duplicity of votes of the same user. El sistema impide la duplicidad de votos del mismo usuario.
- For IP of the user: The system locates the IP of the computer from which the vote is expressed. It will be possible only to vote once from the same machine. Sólo se podrá votar una vez desde la misma máquina.
- For IP and user's name: The two previous options get together. There is verified the user's name and the IP of the voter. Se comprueba el nombre de usuario y la IP del votante.
- For creation of a cookie: In the computer of the voter a small file remains kept with information on the voting. The existence of this file will prevent the emission of the second vote. La existencia de ese archivo impedirá la emisión de un segundo voto.
In any appearance of them it should be trustworthy, but in practice it is not like that. Do I know any user who practises someone, or more of one, of the tricks?? that I quote next:? que cito a continuación:
- To create several user's names: It is very easy to have one or several free mail accounts. A natural person can have several names, each of them associated with a different account. Una persona física puede disponer de varios nombres, cada uno de ellos asociado a una cuenta distinta.
- To change IP: If the Internet connection is done across a router, a reseteo of the same one generates a new IP. A change of machine, much more uncomfortable, produces the same result. Un cambio de máquina, mucho más incómodo, produce el mismo resultado.
- To erase cookie: It is possible to erase the file that keeps the information emptying the cache memory of the navigator.
Detecting that the same person arranges and uses several accounts supposes for the manager of the Web place an added effort. (In menéame.net they have already discovered to more of one). The game with the IP is more difficult to detect on the part of the manager or managers; perhaps, for this motive, it would be advisable not to admit votes with this limitation. El juego con la IP es más difícil de detectar por parte del administrador o administradores; tal vez, por ese motivo, sería recomendable no admitir votos con esa limitación.
What can be the solution? How can the meaning of a voting have value in a Web place? Will it be necessary to create digital certificates, similar to those that there expresses the House of mint and Stamp so that only the users who possess them could vote? The experts will say to us that … The search of a trustworthy system is essential. Do you agree? ¿Será necesario crear certificados digitales, similares a los que emite la Casa de Moneda y Timbre para que sólo los usuarios que los posean puedan votar? Los expertos nos dirán… La búsqueda de un sistema fiable es imprescindible. ¿Estáis de acuerdo?
