Random verification code

Abstract

The invention discloses a random verification code that comprises a random text generation module, a verification code module, a business logic module, a database and the like. According to the invention, user access information is obtained through a system, including user information and access information, such as access address, access time and other dimension parameters. Based on the verification code container selection algorithm, a random text is extracted in the database, verification code characters are then specified in the random text through the verification code module, and a user is notified of verification code selection rules and reminded of the corresponding verification code. If the user is notified of the selection rules, the user only needs to select and input the corresponding verification code to verify. By containing the verification code in the random text, the random verification code improves the security of the verification code system and effectively prevents automatic identification of a machine program.

Description

technical field [0001] The invention relates to system software and the technical field of the Internet, in particular to a random verification code. Background technique [0002] With the development of Internet technology, especially software technology, it provides feasibility based on a random verification code. [0003] At present, in the system login interface, in order to prevent the automatic login of automatic machine programs, the system provides a verification code system on the login interface for defense. The traditional verification code method is a scrambled text image method. With the development of image recognition technology, pure Text and image verification codes can already be read and cracked by machines, and the security needs to be improved. However, overly complex and scrambled verification code images make it difficult for users to read and often require multiple attempts to enter the verification code correctly. The user experience is poor. Howeve...

[0003] At present, in the system login interface, in order to prevent the automatic login of automatic machine programs, the system provides a verification code system on the login interface for defense. The traditional verification code method is a scrambled text image method. With the development of image recognition technology, pure Text and picture verification codes can already be read and cracked by machines, and the security needs to be improved. However, overly complex and scrambled verification code images make it difficult for users to read and often require multiple attempts to enter the verification code correctly. The user experience is poor. However, the verification code is included in a text container selected according to the user's access information, and the position of the designated verification code character is calculated. Although the machine-based reading program may obtain the text of the verification code container, it cannot obtain the text randomly designated by the system. Verification code selection rules. At the same time, clear verification code text is helpful for users to read and select. On the one hand, it improves the security of verification codes, and on the other hand, it facilitates users' reading and input
