Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1A is a schematic flow chart of a verification code generation method based on pinyin according to an embodiment of the present invention, where the method may be applied to a verification code generation apparatus based on pinyin, and as shown in fig. 1A, the method includes:
101. selecting M different verification Chinese characters from a Chinese character library, wherein the verification Chinese characters comprise a prompt Chinese character and at least two to-be-selected Chinese characters, at least one standard Chinese character exists in the to-be-selected Chinese characters, the pinyin first letter of the standard Chinese character is the same as the pinyin first letter of the prompt Chinese character, and M is a positive integer not less than 3;
102. and generating and pushing a verification code to a user according to the prompt Chinese character and the Chinese character to be selected, so that the user selects a Chinese character with the same pinyin first letter as the prompt Chinese character from the Chinese character to be selected for verification according to the verification code.
The Chinese character library may be a conventional known Chinese character library directly, or may be established according to actual verification requirements, which is not limited herein. For example, in order to improve the general practicability of the verification code, the Chinese character library can be established by counting a certain number of common Chinese characters, so that the influence on the accuracy of the verification result caused by that a user does not know uncommon Chinese characters is avoided.
Specifically, if the Chinese character selected by the user is consistent with the standard Chinese character, the verification is successful, otherwise, the verification fails. The value of M may be 7, that is, one prompt chinese character and 6 candidate chinese characters, where the pinyin initial of at least one standard chinese character in the 6 candidate chinese characters is the same as the prompt chinese character, and the value of M is larger, the security of the verification code is higher, but the operation time of the user needs to be taken into consideration. Alternatively, the value of M may be randomly determined each time the verification code is generated.
Optionally, the number of the standard chinese characters may be preset, for example, the number of the standard chinese characters may also be determined according to security requirements and user experience in a balanced manner, or the number of the standard chinese characters may also be determined randomly each time 101 is executed. If the number of the standard Chinese characters is a preset fixed value, in order to ensure the strength and accuracy of verification, the Chinese characters to be selected also comprise at least one interference Chinese character, the pinyin first letter of the interference Chinese character is different from the pinyin first letter of the prompt Chinese character, namely the number of the standard Chinese characters is not more than M-2; if the number of standard Chinese characters is randomly determined every time 101 is executed, the number of the randomly determined standard Chinese characters is only limited to be not more than M-1.
Specifically, the chinese character library may be pre-established, and in practical applications, the established chinese character library may be stored in a database or a memory. It can be understood that after the Chinese character library is established, verification Chinese characters can be selected from the established Chinese character library to generate verification codes in each verification process, and the Chinese character library does not need to be established each time the verification codes need to be generated. In practical application, there are many ways to establish a Chinese character library, as long as the first letter of pinyin of each Chinese character can be obtained based on the Chinese character library. For example, a Chinese character library is established by analyzing and counting the pinyin initial letters of the Chinese characters.
With the scheme of the present embodiment, by way of example, in an actual scenario: when user authentication is required, for example, when an authentication code request sent by a client is received, M different authentication Chinese characters are selected from a pre-established Chinese character library, specifically, the selection strategy is various, for example, random selection or selection according to the difficulty degree of the Chinese characters is performed, a prompt Chinese character and at least two Chinese characters to be selected are obtained, and the pinyin initial letter of at least one standard Chinese character in the Chinese characters to be selected is the same as the prompt Chinese character; after the verification Chinese character is selected, generating a verification code according to a certain format and pushing the verification code to the user according to the prompt Chinese character and the Chinese character to be selected, for example, as shown in fig. 1B, fig. 1B is a schematic diagram of an effect of a generated verification code based on an embodiment of the present invention, wherein the preset format is as follows: clicking the Chinese characters with the same initial sum in the lower part, wherein the king in the double quotation marks is the prompt Chinese character, and the six Chinese characters in the lower part are the Chinese characters to be selected; based on the pushed verification code, the user can select a Chinese character with the same pinyin initial as the pinyin initial of the prompt Chinese character from the Chinese characters to be selected for verification, and still take fig. 1B as an example, that is, the user can select a character with the same pinyin initial as the king from the characters of garden, people, ears, old, characters and cars for verification. It can be known that the Chinese character which is identical to the first letter of the pinyin of the king is 'text'. It is to be understood that the drawings are exemplary embodiments only, and are not intended to limit the present invention to other embodiments, such as the form of questions, the font of Chinese characters, the format of Chinese character arrangement, etc.
The verification code generation method based on the pinyin provided by the embodiment pushes a prompt Chinese character and a to-be-selected Chinese character to a user, the pinyin first letter of at least one Chinese character in the to-be-selected Chinese character is the same as the prompt Chinese character, and the user selects a Chinese character with the pinyin first letter which is the same as the prompt Chinese character from the to-be-selected Chinese character, so that verification is performed according to a selection result of the user.
In order to quickly acquire a verification Chinese character and thereby improve the efficiency of verification code generation, a Chinese character library may be established by using letters as indexes, and accordingly, as shown in fig. 2A, fig. 2A is a schematic flow diagram of a verification code generation method based on pinyin according to a second embodiment of the present invention, and on the basis of the first embodiment, before 101, the method further includes:
201. and counting a Chinese character set corresponding to each letter, and establishing the Chinese character library, wherein the pinyin initial letters of all Chinese characters in the Chinese character set corresponding to each letter are the letters.
Specifically, for each letter, for example, all 26 letters, that is, letters a to z, are indexed by using the letter, and based on a rule of a pinyin first letter, a chinese character set corresponding to each letter is counted by establishing a mapping relationship between the letter and the chinese character, and finally a chinese character library is established, where the pinyin first letter of all the chinese characters in the chinese character set corresponding to each letter is the letter. The letters described herein are not case-specific, and for example, the Chinese characters corresponding to the letter a include but are not limited to: o, an and; the Chinese characters corresponding to the letter c include but are not limited to: only, layer; the Chinese characters corresponding to the letter t include but are not limited to: he, Te, Tao and Tao.
Further, in practical applications, there may be letters, e.g., i and u, for which no Chinese character is the initial pinyin, and accordingly, the letters may be eliminated in advance in order to further reduce the time taken to verify the selection of a Chinese character and avoid unnecessary searching. Correspondingly, on the basis of the embodiment shown in fig. 2A, after 201, the method may further include: and clearing the invalid letters in the letters and the Chinese character set corresponding to the invalid letters, wherein the Chinese character set corresponding to the invalid letters is empty.
For example, assuming that the chinese character library includes a chinese character set corresponding to 26 letters before the removal processing, based on the present embodiment, if the chinese character set corresponding to the letters i and u is determined to be empty, the two letters are deleted from each letter, the chinese character set corresponding to the two letters is correspondingly deleted, and the remaining 24 letters and the chinese character sets corresponding to the letters are retained. Correspondingly, when the verification Chinese character is selected from the Chinese character library subsequently, the selection is only carried out from the Chinese character set corresponding to 24 letters, so that the selection speed and efficiency are improved.
In the embodiment, the invalid letters with the corresponding Chinese character set being empty are removed from each letter, so that unnecessary processing in the process of selecting the verification Chinese character is avoided, and the generation efficiency of the verification code is improved.
In addition, in practical applications, there may be some polyphones, for example, the "tail" has multiple pronunciations, i.e., "wei" and "yi", and accordingly, in order to avoid inaccurate verification results caused by polyphones, the words may be cleared in advance. Correspondingly, on the basis of the embodiment shown in fig. 2A, after 201, the method may further include: and clearing polyphone characters in the Chinese character library, wherein the first phonetic letter of the polyphone characters is multiple.
According to the embodiment, polyphones with different pronunciations are eliminated from the Chinese character library, so that the influence of the polyphones on the verification result is avoided, and the verification accuracy is improved.
The above two embodiments can be implemented separately or in combination, for example, to eliminate invalid letters and their corresponding Chinese character sets, and also to eliminate polyphones. When the two are combined for implementation, the execution sequence is not limited.
Based on the Chinese character library in the embodiment, letters can be used as indexes, and then verification Chinese characters are selected from Chinese character sets corresponding to the letters. As shown in fig. 2B, fig. 2B is a schematic flow chart of another verification code generation method based on pinyin according to a second embodiment of the present invention, and on the basis of the implementation shown in fig. 2A, 101 may specifically include:
1011. randomly selecting N first letters from the letters, wherein N is a positive integer and is less than M;
1012. and randomly selecting at least one Chinese character from the Chinese character set corresponding to each first letter to obtain the M different verification Chinese characters.
Specifically, when the verification code needs to be generated, N letters are randomly selected from each letter, then at least one Chinese character is randomly selected from a Chinese character set corresponding to each letter in the N letters, and finally, M different verification Chinese characters are obtained.
In a first practical manner, N may be a preset value, and specifically, when N is the preset value, the candidate chinese character further needs to include at least one interfering chinese character, where a pinyin first letter of the interfering chinese character is different from a pinyin first letter of the prompt chinese character, that is, N is greater than 1. Further, in the first implementable manner, N may be set to M-1, that is, at least one chinese character is selected from the chinese character set corresponding to the M-1 letters, respectively, to obtain M verification chinese characters, it can be understood that in this case, only the pinyin first letters of two chinese characters are the same in the verification chinese characters, that is, only one standard chinese character exists in the chinese character to be selected, the rest are interference chinese characters, and the pinyin first letters of the interference chinese characters are all different.
In the second implementable manner, the value of N may also be randomly determined each time 1011 is executed, and in this implementation, a case that all the chinese characters to be selected are standard chinese characters may occur in a certain verification, for example, when N is 1, i.e., a verification chinese character is selected from a chinese character set corresponding to the same letter, but since the value of N is randomly determined each time 1011 is executed, the accuracy of verification is not affected. In the second embodiment, N may also be set to be greater than 1, that is, at least one verification chinese character is selected from the chinese character set corresponding to two letters, and accordingly, at least one interfering chinese character may exist in the candidate chinese character, and the first pinyin letter of the interfering chinese character is different from the first pinyin letter of the prompt chinese character.
According to the embodiment, the difficulty of cracking the verification code can be further improved and the accuracy and the reliability of verification can be improved by adjusting the relative number of the standard Chinese characters and the interfering Chinese characters.
The verification code generation method based on pinyin provided by the embodiment takes letters as indexes, and establishes a Chinese character library by counting Chinese character sets corresponding to the letters, so that verification Chinese characters can be selected from the Chinese character library more quickly and accurately, and the efficiency and the accuracy of verification code generation are improved.
Fig. 3A is a schematic flow chart of a verification code generation method based on pinyin according to a third embodiment of the present invention, as shown in fig. 3A, on the basis of the first embodiment or the second embodiment, the generating a verification code according to the prompt chinese character and the candidate chinese character in 102 may specifically include:
1021. randomly selecting a background image from a preset image library;
1022. and generating the verification code by taking the background picture as a display background according to the prompt Chinese character and the Chinese character to be selected.
Specifically, based on the scheme of the first embodiment or the second embodiment, after the verification Chinese characters are selected from the Chinese character library, the background graph is randomly selected from the graph library, and the prompt Chinese characters and the Chinese characters to be selected are added to the background graph according to a preset format by using the background graph as the canvas according to the prompt Chinese characters and the Chinese characters to be selected in the verification Chinese characters, so as to generate the final verification code. It can be understood that the patterns in the background image can interfere the cracking program to identify the Chinese characters, so that the failure rate of cracking the verification code is increased, and the accuracy and the reliability of verification are improved.
Further, fig. 3B is a schematic flow chart of another pinyin-based verification code generation method according to a third embodiment of the present invention, as shown in fig. 3B, and on the basis of the implementation manner shown in fig. 3A, after 102, the method may further include:
301. caching a first coordinate of the standard Chinese character in the background image;
302. acquiring a second coordinate of the Chinese character selected by the user in the background image;
303. and detecting whether the Chinese character selected by the user is consistent with the standard Chinese character or not by comparing whether the first coordinate is consistent with the second coordinate or not.
Specifically, in the embodiment, the background map is used as the canvas, the Chinese characters to be selected are added to the background map according to the preset format, the coordinates of the standard Chinese characters in the background map are recorded in the cache as the correct "answer", the coordinates of the standard Chinese characters in the background map are compared with the coordinates of the Chinese characters selected by the user subsequently, whether the coordinates of the standard Chinese characters are consistent with the coordinates of the Chinese characters selected by the user is determined, if the coordinates of the Chinese characters selected by the user are consistent with the coordinates of the standard Chinese characters, the verification is successful, and if the coordinates of the Chinese.
According to the pinyin-based verification code generation method provided by the embodiment, the prompt Chinese characters and the Chinese characters to be selected from the Chinese character library are added into the background image according to the preset format, and the cracking program can be interfered to identify the Chinese characters by combining the patterns in the background image, so that the failure rate of cracking the verification code is increased, and the accuracy and the reliability of verification are improved.

a second selecting unit 412, configured to randomly select at least one Chinese character from the Chinese character set corresponding to each first letter, so as to obtain the M different verified Chinese characters.
Specifically, when the verification code needs to be generated, the first selecting unit 411 first randomly selects N letters from each letter, and the second selecting unit 412 then randomly selects at least one Chinese character from the Chinese character set corresponding to each letter in the N letters, thereby finally obtaining M different verification Chinese characters.
In a first practical manner, N may be a preset value, and specifically, when N is the preset value, the candidate chinese character further needs to include at least one interfering chinese character, where a pinyin first letter of the interfering chinese character is different from a pinyin first letter of the prompt chinese character, that is, N is greater than 1. Further, in the first implementable manner, N may be set to M-1, that is, at least one chinese character is selected from the chinese character set corresponding to the M-1 letters, respectively, to obtain M verification chinese characters, it can be understood that in this case, only the pinyin first letters of two chinese characters are the same in the verification chinese characters, that is, only one standard chinese character exists in the chinese character to be selected, the rest are interference chinese characters, and the pinyin first letters of the interference chinese characters are all different.
In the second implementable manner, the value of N may also be randomly determined each time a verification chinese character is selected, and in this implementation, a situation that all chinese characters to be selected are standard chinese characters may occur in a certain verification, for example, when N is 1, a verification chinese character is selected in a chinese character set corresponding to the same letter, but since the value of N is randomly determined each time a verification chinese character is selected, the accuracy of verification is not affected. In the second embodiment, N may also be set to be greater than 1, that is, at least one verification chinese character is selected from the chinese character set corresponding to two letters, and accordingly, at least one interfering chinese character may exist in the candidate chinese character, and the first pinyin letter of the interfering chinese character is different from the first pinyin letter of the prompt chinese character.
According to the embodiment, the difficulty of cracking the verification code can be further improved and the accuracy and the reliability of verification can be improved by adjusting the relative number of the standard Chinese characters and the interfering Chinese characters.
The verification code generation device based on pinyin takes letters as indexes, establishes a Chinese character library by counting Chinese character sets corresponding to the letters, so that verification Chinese characters can be selected from the Chinese character library more quickly and accurately, and the efficiency and the accuracy of verification code generation are improved.
