A password input method based on two-stage conversion, particularly as follows: (1) taking password composition symbols as original basic symbols, and randomly selecting intermediate basic symbols therefor; (2) randomly ordering the original basic symbols and the intermediate basic symbols respectively and making same in one-to-one correspondence according to a spatial position relationship to form first-stage correlation; (3) randomly re-ordering the original basic symbols and the intermediate basic symbols again respectively and making same in one-to-one correspondence according to the spatial position relationship to form second-stage correlation; (4) with regard to a current password composition symbol to be input, querying an original basic symbol corresponding thereto according to the second-stage correlation first and then the first-stage correlation so as to complete an input operation on the current password composition symbol to be input; and (5) repeating steps (2)-(4) until the input of all the password composition symbols is completed. The method can be well adapted to a currently and widely used password input environment, and can effectively avoid a password stealing problem at the same time, thereby improving the security during password input. |
