Method and device for realizing verification code

A device for realizing a verification code comprising:

• a processor configured to:
• determine a language currently used by a user on the device;
• select, from a plurality of available character verification code languages, a user language determined to being currently used by the user;
• obtain a character verification code comprising characters in the same language as the user language, wherein the character verification code comprises a first part comprising correct characters and a second part comprising an incorrect character based on a priori knowledge;
• obtain a sentence from a local text;
• extract randomly a character from the sentence and perform a random transformation on the extracted character to produce the incorrect character based on the a priori knowledge in the sentence to obtain the character verification code;
• wherein when the extracted character is in Chinese, performing the random transformation on the extracted character to produce the incorrect character in the sentence to obtain the character verification code comprises:
• determining synonym characters of the extracted character in a synonym character library, and
• performing the random transformation on the extracted character by using a character other than the synonym characters of the extracted character to produce the incorrect character;
• a display configured to display the character verification code for performing identity verification and prompt inputting a correct character corresponding to the incorrect character in the character verification code;
• wherein the processor is further configured to:
• receive verification information;
• and
• determine that the identity verification is successful when the verification information corresponds to the correct character based on the a priori knowledge, and determine that the identity verification fails when the verification information does not correspond to the correct character based on the a priori knowledge.

A verification method, comprising:

• determining a language currently used by a user on a verification executer computing device;
• selecting, from a plurality of available character verification code languages, a user language determined to being currently used by the user;
• obtaining a character sequence comprising characters in the same language as used by the user language, wherein the character sequence comprises a first part and a second part;
• generating a verification code based on the character sequence, wherein the generated verification code comprises a first part and a second part, the first part of the verification code comprises the same characters as the first part of the character sequence and the second part of the verification code is different from the second part of the character sequence, wherein generating the verification code comprises:
• obtaining a sentence from a local text on a verification executer;
• extracting randomly a character from the sentence, and
• performing a random transformation on the extracted character to produce an incorrect character based on a priori knowledge in the sentence,
• wherein when the extracted character is in Chinese, the performing a random transformation on the extracted character to produce the incorrect character based on the a priori knowledge comprises:
• determining synonym characters of the extracted character in a synonym character library, and
• performing the random transformation on the extracted character by using a character other than the synonym characters of the extracted character to produce the incorrect character;
• displaying the verification code;
• receiving verification information inputted by the user corresponding to the second part of the verification code;
• comparing the verification information inputted by the user with the second part of the character sequence;
• and
• determining that a verification of the user is successful in response to determining that the verification information is consistent with the second part of the character sequence and determining that the verification of the user fails in response to determining that the verification information is not consistent with the second part of the character sequence.
