In a computer data context, cryptographic methods have been developed (see digital signature and challenge-response authentication) which are currently not spoofable if and only if the originator's key has not been compromised.
No contexto de datos computacionais, os métodos de criptografía son desenvoltos (vexa sinatura dixital e autenticación desafío-resposta) son actualmente non rompibles se e só se a chave do emisor non é comprometida.
