Abstract

The invention is suitable for the technical field of computer application, and provides a verification code generation method and device, and the method comprises the steps: generating a character sequence, wherein the character sequence is composed of letters and numbers; extracting code types corresponding to characters in the character sequence from a preset code type library; and deforming andcombining the code types to obtain the verification code. Through determining code type corresponding to a character sequence, deforming and combining the code types to obtain a verification code; and finally, generating a character matrix consisting of characters. In the character matrix, the characters with contrast form the image which can be recognized by human eyes and is composed of the characters, the requirement that the characters can be recognized by human beings but are difficult to recognize by machines is met through the display mode of the image, the use requirement of the character terminal is met, and the safety of verification code verification in the character terminal is also improved.

Description

technical field [0001] The present application belongs to the technical field of computer applications, and in particular relates to a verification code generation method and device. Background technique [0002] The traditional picture-based verification code technology has been widely used in webpages, application logins, user verification and other environments with picture display capabilities. It is a mature method that can prevent mechanical brute force cracking and enhance the security of weak passwords. However, in environments such as serial ports, remote terminal protocols, and secure shell protocols, where only characters can be displayed, this method of displaying verification codes through pictures is useless. However, in many resource-constrained devices, character terminals It is the only way of remote interaction. For example, on the character terminal of the bank, the login and verification can only be realized through character verification. Therefore, the...
