I'm not certain of the intent of the question but it sounds like what is being asked is how you can know the actual identity of someone from their public key - i.e. how you can know that the public key really belongs to the person it purports to belong to. PKI (public key infrastructure) is one way to establish with reasonable certainty that a key really belongs to the entity that is claimed. PKI uses a system of Certificate Authorities (CA) and Registration Authorities (RA). At the top of the chain is the Registration Authority that everyone trusts. Users register their public keys with the RA. CA's also register their certificates withe the RA along with proof that they are who they say they are. CA's are repositories of public keys that the public can access. They sign the keys with their own certificates vouching for the identity of the public key owner. The identity of the CA may, in turn, be vouched for by an RA or higher CA who sign the certificate of that particular CA.

When you reference a "public key" you are implying that the file has been encrypted using "asymmetric cryptography". In asymmetric cryptography, encryption and decryption depend on a key PAIR. The user retains their private key and publishes their public key. Anyone can encrypt a file using the user's public key and send it to them. The only person who should be able to decrypt a file encrypted with that public key is the holder of the private key - which, unless the user has made the mistake of sharing their private key - means that only the original user can decrypt the messages sent to them. Most of the asymmetric encryption algorithms use pretty much the same method to decrypt that was used to encrypt, but use the "other" key from the key pair. Messages encrypted using the private key can only be decrypted using the public key - which provides some authentication that the message indeed came from the holder of the private key. Messages encrypted using the public key can only be decrypted by the holder of the private key, so messages sent to them should be secure.
