Abstract
Disclosed embodiments relate to verifying identities based on identity-inherent data that is inaccessible to the system. Techniques include receiving, from a client, an encrypted token, the encrypted token having been encrypted at the client using a cryptographic key created at the client based on identity-inherent data of an identity of the client; wherein the identity-inherent data of the identity is not itself received by the system, and wherein the cryptographic key is accessible only to the client; and storing the encrypted token in association with a hash of a decrypted version of the encrypted token to allow for comparing the stored hash with a created hash and determining whether to verify the identity based on a result of the comparing.
