methodologies to acoustic examination. Together with human in authentication protocols, whereas guaranteeing, isn't
straightforward in light-weight of their restricted capability of calculation and remembrance. We tend to exhibit however
careful mental image define will improve the safety yet because the convenience of authentication. We tend to propose 2
visual authentication protocols: one may be a one-time-password protocol, and also the alternative may be a passwordbased authentication protocol. Our approach for real arrangement: we tend to have the capability attain to associate
abnormal state of easy use whereas fulfilling demanding security requirements.
