s61, a verification account and a verification password are preset at the server side, and when logging in, a user inputs a login account and a login password;
s62, mapping the input login account characters and login password characters with preset login account characters and login password characters one by one;
s63, performing hash operation on the preset login account corresponding to the input login account characters to obtain a hash account; carrying out hash operation on a preset login password corresponding to the input login password character to obtain a hash password; judging whether the obtained hash account number is the same as the verification account number stored by the server side and whether the obtained hash password is the same as the verification password stored by the server side;
and S64, if the verification is passed, the login is successful.
9. The control method of the multipoint videoconference screen display system of claim 7, wherein step S63 comprises the steps of:
s630, making the error frequency Q equal to 0;
s631, the server determines whether the obtained hash account is consistent with the verification account stored by the server:
if the obtained hash account is consistent with the verification account stored in the server, executing step S632;
if the obtained hash account is inconsistent with the verification account stored by the server, prompting the user to input the login account and the login password again; q ═ Q + 1; step S633 is performed;
s632, the server determines whether the obtained hash password is consistent with the verification password stored in the server:
