Auditoría de Limitación de Riesgo

La auditoría de limitación de riesgo es un procedimiento que proporciona una fuerte evidencia estadística de que el resultado de la elección es correcto o tiene una alta probabilidad de corregir un resultado que no coincidiría con el recuento manual completo de las boletas. La auditoría en sí requiere que los seres humanos examinen y verifiquen más papeletas en contiendas cerradas y menos papeletas en contiendas con márgenes más amplios.

  • The random seed is generated by numerous people, including members of the public, rolling ten-sided dice.
  • The random seed is used to generate the random sequence of ballots that is audited. 
  • The seed is used in conjunction with Ron Rivest's (MIT) "sampler.py" pseudo-random number generator and the ballot manifest to generate the publicly verifiable random sample.  Observers can reproduce the sample independently, using for example the Pseudo-Random Number Generator using SHA-256 at https://www.stat.berkeley.edu/~stark/Vote/auditTools.htm
