A verification code generation verification method and device

Abstract

Disclosed is a method for generating and verifying verification codes, which comprises: displaying a verification code display area on a touch display module, the verification code display area comprising at least one verification code element that can be identified by a user (S11); sensing a touch action of the user on the touch display module, and determining the position of the touch action on the touch display module (S12); and comparing whether the position of the touch action of the user on the touch display module is the same as that of the verification code element, so as to determine whether the verification code input is correct (S13). The method for generating and verifying verification codes facilitates the verification code input verification of the user, and is convenient in operation and has a desirable verification effect. Further disclosed is a device for generating and verifying verification codes.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for generating and verifying verification codes. Background technique [0002] A captcha is a public, fully automated process that distinguishes between a computer program and a human being who requests access. Verification codes are often used to prevent Trojan horses and other programs from maliciously cracking passwords, swiping tickets, and flooding forums. The verification code is usually composed of some lines and some irregular characters, and its main function is to prevent hackers from stealing the password after digitizing it. The current mainstream verification code forms are as follows: [0003] 1. Consisting only of numbers and letters, which may be all letters or numbers, random multi-digit strings. This kind of verification code is the most primitive, and its verification effect is almost zero in the current technical environm...

Problems solved by technology

[0003] 1. It is only composed of numbers and letters, which may be all letters or numbers, random multi-digit strings, this kind of verification code is the most primitive, and its verification effect is almost zero in the current technical environment

[0004] 2. Random numbers + random uppercase English letters + random interference pixels + random positions + random length image verification codes; randomly generated, verification is more difficult, higher security but not conducive to user input

The above-mentioned technology has many disadvantages. First, the user needs to switch to the keyboard to input characters after entering the user name and password each time. Especially if the character input needs to be performed on the touch screen, the process will be cumbersome and the user experience is not good. Good, causing confusion for users

Secondly, verification codes often appear to be unrecognizable by users due to text stacking, forcing users to constantly refresh the verification code picture

Again, the purpose of entering the verification code itself is to prevent malicious program attacks and keep the server system in a safe state, but in actual situations, most of them are preventing users from using them happily, causing users distress, and at the same time, they have not been improved in terms of security. significant enhancement
