Many clients will not be capable of ascertain no matter if their machine is reliable, i.e. it could possibly include malware. One resolution is to exploit visible cryptography for authentication. the writer generalizes this idea to human decipherable encryption schemes and establishes a dating to CAPTCHAS.
