US Patent 10462112 Secure distributed authentication data

Disclosed embodiments relate to systems and methods for secure distributed authentication data. Techniques include identifying asserted authentication data associated with the request, generating an encryption key based on the asserted authentication data, generating a non-restorable digital representation of the asserted authentication data, retrieving an encrypted non-restorable digital representation of authentication data associated with the client identity, decrypting the retrieved encrypted non-restorable digital representation of authentication data using the encryption key, comparing the decrypted non-restorable digital representation of authentication data to the non-restorable digital representation of asserted authentication data; and providing a token for use in an authentication process for the client identity upon determining, based on a match between the stored non-restorable digital representation of authentication data and the non-restorable digital representation of version of the asserted authentication data.
