<p>A method for interactive authentication, which includes the steps of that: the client information is pre-stored in the data-base, and the client information includes a basic authentication factor and a location authentication factor; the client terminal collects the location authentication factor of the client real time; a reversible algorithm is being carried out to the collected location authentication factor to obtain an encrypted string; both the encrypted string and the basic authentication factor are sent to an authentication server; and a reversible algorithm is being carried out to the encrypted string to obtain the collected location authentication factor by the authentication server; and the location authentication factor obtained by the authentication server is compared with the client information pre-stored to perform authentication. The basic authentication factor and the location authentication factor of the client are bound together by the present invention, thus improving the security of authentication.</p> |
