Peeping-proof password input method

Abstract

The invention discloses a peeping-proof password input method. When a user requests a password verification, a system generates a random key comparison table, and meanwhile the random key comparison table is displayed on a displayer through a virtual digital keyboard; and virtual digital keys of the virtual digital keyboard are in one-to one correspondence with subscripts. The subscripts are displayed periodically in a manner of momentary flashing after the subscripts are spaced at intervals. The subscripts are taken as replacement digits to be input after the user observes flashing of the subscripts according to password digits clearly. After the system receives the input, the key comparison table is looked up so that the replacement digits are reduced into password digits to be recorded and stored, and then subscript units of the key comparison table are refreshed, so that a new group of digits are generated randomly. The finish confirmation is given after the user finishes inputting completely, the recorded and stored password digits are combined into passwords in sequence and submitted to a verification system for verification after the system receives a confirmation instruction. According to the peeping-proof password input method, random changing and flashing of the subscripts of the virtual digital keyboard are used, so that the subscripts are difficult to see clearly and memorize, the password cannot be deduced reversely, and the security of password input is guaranteed.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to an anti-peeping password input method. Background technique [0002] In daily life, passwords are an important means of verifying user identities. ATMs in banks, POS machines in shopping malls, trading terminals in securities companies, and access control at work and living places all need to enter passwords to verify identities. But these are all public places, so the environment for entering passwords is openly exposed, which inevitably makes lawbreakers have an opportunity to steal user passwords by means of peeping around. For this reason, people have to be cautious when entering passwords, or change passwords from time to time, etc., but this is easy to cause passwords to be forgotten, which brings a lot of inconvenience and trouble to people, and even causes huge deposits to be stolen due to passwords being peeped. , Bank cards are maliciously swiped and ident...

Problems solved by technology

In this scheme, the key value of each key is randomly replaced by the corresponding digital display unit, but it is fixed during the password input and remains displayed all the time, although it places the random digital display unit inside the key so that the viewing angle is limited. However, the user must need a viewing angle that is easy to observe during use, so it is impossible to completely prevent the digital display unit from being peeped, so peepers can easily see the key operation and steal the password as long as they are within the visible range; in addition, the The solution needs to upgrade the keyboard hardware, which will increase the difficulty, cost and system risk of the system
