You're looking for an anti-Sybil defence. Generally, some chain-of-trust involving nonduplicable demonstration of identity.
Depending on the strength of defence required, anything from a low-cost registration fee (see Metafilter) to some form of recommendation-and-vetting or simultaneous in-person token-granting event (simultaneous to avoid entities being in two places at once). And auditing for abuse.
There have been several proposals for such systems also assuring some level of anonymity.
It's unlikely any approach will be perfect, though an arbitrary level of assurance is likely possible at some cost.
Note that surreptitiously fingerprinting and preemptively certifying to establish entity uniqueness are vastly different from a user awareness and concent perspective.
