Problems solved by technology
[0003] In order not to be maliciously attacked by attackers, the verification code is usually fused with the background image and the string image and deformed. After processing, the content in the string image will not be easily recognized by the user, such as "6", "9", When "b" appears at the same time, "p" and "q" appear at the same time, or "0" and "o" appear at the same time, etc., when these similar characters are deformed and arranged as verification codes, when normal users recognize Confusion often occurs, leading to input errors and affecting verification efficiency

Embodiment 1
[0037] like figure 1 As shown, an embodiment of the present invention provides a method for generating a verification code of a digital-to-Chinese character type, comprising the following steps:
[0038] Generate the corresponding Chinese character set combination according to the corresponding Chinese pronunciation mapping from 0 to 9;
[0039] Receive the verification request sent by the user terminal;
[0040] Randomly generate a random number of the specified number of digits according to the verification request, such as 4 digits, 3498;
[0041] According to the Chinese pronunciation mapping of each number 3, 4, 9 and 8, the corresponding Chinese character set combination is generated. When the numbers 3, 4, 9 and 8 are converted into Chinese characters, they are mapped on the code, for example, "3" is mapped to "three" , "mountain", "umbrella", etc. a Chinese character set combination, "4" is mapped to a Chinese character set combination of "four", "is", "thinking", et...

The invention discloses a method for generating a verification code of digital-to-Chinese character type, comprising the following steps: generating a corresponding Chinese character set combination according to the Chinese pronunciation mapping corresponding to 0 to 9; receiving a verification request sent by a user terminal; randomly generating a verification code according to the verification request, The verification code contains not less than one number and there is a certain arrangement between the numbers; extract the Chinese character set combination corresponding to each number in the verification code; randomly extract a Chinese character from the Chinese character set combination as the Chinese character verification character, and use the Chinese character verification character Generate a Chinese character verification code picture according to a preset arrangement rule and display it to the user terminal; when the number input by the user terminal matches the corresponding Chinese character verification code, the verification is successful. The invention generates a verification code with unique identification based on Chinese pronunciation, avoids confusion when users identify, and improves user verification efficiency.
Description
technical field [0001] The invention relates to the technical field of computer networks, in particular to a verification code generation method and verification system of the type converted from numbers to Chinese characters. Background technique [0002] "Captcha" in English is CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart), which translates as "Automatic Turing Test to Distinguish Computers and Humans". As the name suggests, it is used to distinguish computers from humans. In the CAPTCHA test, the computer as the server automatically generates a question for the user to answer. This question can be generated and judged by a computer, but only a human can answer it. Since computers cannot answer CAPTCHA questions, without the CAPTCHA, attackers use unwanted programs to automatically register numerous web service accounts, which the attacker can then use to cause trouble for other users, such as by sending spam or by logging in repeate...
