4) Digital Signature Certificate and PKI: This is the highest level of security. The PKI generates 2 long numbers called as key one being public and the other private. This needs a CA to save it with security. Example: DocuSign

5) PKI + Biometrics: These days even the mobile device uses the PKI and biometrics for authorization. Even the smart cards being used by the several Organization also contains this kind of security techniques. Example: ICICI Bank Mobile App.
