Security password setting and verification method

Abstract

The invention relates to a safe password setting and verifying mode. The safe password setting and verifying mode is characterized by comprising the following steps: (A) basic passwords are set by a user and are composed of a plurality of orderly character codes; (B) an encryption principle is set, encryption operation is carried out on the basic passwords according to the encryption principle to form verifying passwords including valid character codes capable of being used for verifying the user identity and / or position information of the valid character codes, and encryption input prompts coincident with the encryption principle are given to the user; (C) composition of the input passwords is appointed, wherein the input passwords comprise valid codes needing character code value verifying and / or character code value position verifying and interference codes which are at least one bit in length and are used for hiding the positions of the valid codes; (D) when character code values of the valid codes in the passwords input by the user at present and / or the character code position information are / is coincident with information included by the verifying passwords, it is judged that the current passwords is correctly input by the user, and verification of the passwords is successful. By means of the safe password setting and verifying mode, the password inputting safety can be greatly improved, and the passwords are effectively prevented from being stolen and decoded.
