[0041] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] With the development of the Internet, spam, fake users, automated programs accessing websites and other illegal behaviors have caused increasing security threats. In online shopping, registering website accounts and other behaviors, people or programs often maliciously attack or use automated programs to forge operations, causing great trouble to data protection.

[0043] Verification codes can use machine learning models to analyze and learn the characteristics of our online usage behavior, and comprehensively analyze these characteristics to effectively distinguish between human users and automated programs. Therefore, verification codes can identify user identities based on user behavior. In order to prevent access and malicious behavior by some automated programs, verification codes have been widely used on the basis of traditional text, number, and sliding verification codes. At present, there are many types of traditional verification codes, such as traditional text verification code images, digital verification codes (such as verification through mobile phone text messages), sliding verification codes (such as verification through graphics), etc. However, traditional verification codes are easily cracked by black industry programs, have poor security, and the verification operation is cumbersome, and user verification cannot be implemented safely and conveniently.

[0044] Based on this, the embodiments of the present invention provide a verification code generation method, device and electronic device. The technology can be applied to applications that require identification of a verification machine and a real user.

[0045] To facilitate understanding of this embodiment, a verification code generation method disclosed in an embodiment of the present invention is first described in detail. The method is applied to a server, and the server is connected to a client for communication. Figure 1As shown, the method includes:

[0046] Step S102, if a verification code acquisition request is received from the client, obtain a first quantity of candidate Chinese characters and the pinyin of each candidate Chinese character.

[0047] The above-mentioned server refers to a computer system that undertakes service functions in a network system, that is, a computer system responsible for receiving requests from the client, processing these requests, and then generating responses and sending them back to the client. The server can provide services for the client, such as providing resources to the client, saving client data, etc.

[0048] The above-mentioned client, also known as the user side, refers to a program that provides local services for the client corresponding to the server. Except for some applications that only run locally, it can generally be installed on ordinary client computers and needs to cooperate with the server to run.

[0049] Generally speaking, the client can be the computer or mobile phone software we use; the server can be the server that stores web pages and database data.

[0050] The above-mentioned first quantity can be a preset value according to verification requirements. Specifically, the value of the first quantity can be determined by balancing the security needs of the actual application scenario and the user experience. Among them, the larger the value of the first quantity, the higher the security of the verification code. However, at the same time, it is necessary to consider that the operation time of the user cannot be too long. Therefore, generally, the value of the first quantity is usually a positive integer not less than 4 and not greater than 10. For example, the value of the first quantity can be 4, 5, 6, etc.

[0051] In the specific implementation process, the client and the server are in a communication connection. When user verification is required, if the server receives a verification code acquisition request from the client, it can obtain a first quantity of candidate Chinese characters and the pinyin of each candidate Chinese character from a pre-established Chinese character library. Specifically, 4 candidate Chinese characters can be randomly selected from the pre-established Chinese character library, such as "我 (wo)", "要 (yao)", "是 (shi)", "手 (shou)" respectively, and obtain the pinyin "wo" corresponding to "我", the pinyin "yao" corresponding to "要", the pinyin "shi" corresponding to "是", and the pinyin "shou" corresponding to "手".

[0052] Step S104, select a second quantity of candidate Chinese characters from the first quantity of candidate Chinese characters as verification Chinese characters, and randomly sort the pinyin of each verification Chinese character to obtain the target pinyin order.

[0053] The above-mentioned second quantity can be preset in accordance with the balance of security requirements and user experience, or can be randomly determined before generating the verification code each time. Whether it is a preset fixed value or a randomly determined random value, in order to ensure the strength and accuracy of verification, the above-mentioned second quantity of verification Chinese characters is usually not greater than the first quantity - 1, that is, at least one interfering Chinese character is included in the first quantity of candidate Chinese characters obtained. Moreover, since it is necessary to randomly sort the pinyins corresponding to each verification Chinese character in the selected second quantity to obtain the target pinyin order, the number of verification Chinese characters should also be a positive integer not less than 2.

[0054] In the specific implementation process, assuming that the first quantity (for example, 4) of candidate Chinese characters is obtained, the second quantity of candidate Chinese characters can be selected from the 4 candidate Chinese characters as verification Chinese characters. Among them, the second quantity can be 3 (4 - 1 = 3, which is equivalent to including one interfering Chinese character in the first quantity of candidate Chinese characters), or can be 2 (equivalent to including two interfering Chinese characters in the first quantity of candidate Chinese characters).

[0055] For example, 3 candidate Chinese characters (such as "yao", "shi", "shou") can be randomly selected from 4 candidate Chinese characters (such as "wo", "yao", "shi", "shou") as verification Chinese characters, and the pinyins ("yao", "shi", "shou") of each verification Chinese character are randomly sorted to obtain the target pinyin order (such as "shou→yao→shi").

[0056] Optionally, 2 candidate Chinese characters (such as "shi", "shou") can also be randomly selected from 4 candidate Chinese characters (such as "wo", "yao", "shi", "shou") as verification Chinese characters, and the pinyins ("shi", "shou") of each verification Chinese character are randomly sorted to obtain the target pinyin order (such as "shou→shi").

[0057] In actual implementation, the more the number of pinyins of verification Chinese characters in the above-mentioned target pinyin order (equivalent to the larger the value of the second quantity), the higher the security of the verification code. Therefore, generally, the larger value corresponding to the second quantity is usually selected (for example, the second quantity can be 3 and 2, because 3 is greater than 2, and usually 3 is selected) as the number of verification Chinese characters.

[0058] Step S106, generate a verification code according to the first quantity of candidate Chinese characters and the pinyin order, and send it to the client, so that the user can verify by selecting each verification Chinese character from the candidate Chinese characters in accordance with the target pinyin order.

[0059] In the specific implementation process, after determining the target pinyin order, a verification code can be generated according to the first quantity of candidate Chinese characters and the pinyin order in a certain prompt format and sent to the client for further display to the user. For example, as Figure 2 shown Figure 2 Schematic diagram of the effect of a verification code provided by an embodiment of the present invention. Among them, the preset prompt format is: click on the Chinese characters in the figure according to the target pinyin order "", and "shou→yao→shi" in the double quotes is the target pinyin order. The 4 Chinese characters in the figure are the candidate Chinese characters; based on the sent verification code, the user can click on the Chinese characters in sequence according to the target pinyin order from the 4 candidate Chinese characters for verification.

[0060] Still taking Figure 2 as an example, that is, the user can verify by selecting Chinese characters from "wo", "shi", "yao", "shou" according to the target pinyin order "shou→yao→shi". It can be seen that the order of clicking and selecting Chinese characters corresponding to the target pinyin order "shou→yao→shi" is "shou→yao→shi". Specifically, if the verification pinyin order formed by the pinyins corresponding to each selected Chinese character according to the selection order is consistent with the target pinyin order, the verification is successful; otherwise, the verification fails. It can be understood that the figure is only an example implementation method, and does not limit other specific implementation methods of the present solution. For example, the prompt format, the font and size of Chinese characters, the format of Chinese character arrangement, etc.

[0061] The above verification code generation method is applied to a server communicatively connected to a client. The method includes: if a verification code acquisition request from the client is received, select a second quantity of candidate Chinese characters from the acquired first quantity of candidate Chinese characters as verification Chinese characters, and randomly sort the pinyins of each verification Chinese character to obtain a target pinyin order; generate a verification code according to the first quantity of candidate Chinese characters and the pinyin order, and send it to the client, so that the user can verify by selecting each verification Chinese character from the candidate Chinese characters according to the target pinyin order. This method randomly sorts the pinyins of each verification Chinese character to obtain a target pinyin order, allowing the user to click on Chinese characters in the target pinyin order for user verification, which can make the verification code not easily cracked, thus having stronger security, and the verification operation is relatively convenient, improving the user experience.

[0062] An embodiment of the present invention also provides another verification code generation method, which is implemented on the basis of the method in the above embodiment; as Figure 3 shown, the method includes the following steps:

[0063] Step S202, if a verification code acquisition request from the client is received, obtain a first quantity of candidate Chinese characters from a preset Chinese character library, and the pinyin of each candidate Chinese character; among them, the Chinese character library includes multiple single-character Chinese characters.

[0064] The above Chinese character library (which can also be called a word library) can be a publicly known Chinese character library, or a Chinese character library established according to actual verification requirements. This embodiment does not limit it here. For example, in order to improve the general practicability of the verification code, a Chinese character library can be established by counting a certain number of Chinese characters and their corresponding pinyin. Specifically, each Chinese character and its corresponding pinyin can be stored in the Chinese character library one by one to avoid affecting the accuracy of the verification result due to the user not knowing rare Chinese characters or their pinyin.

[0065] In practical applications, the above Chinese character library can be established in advance, and the established Chinese character library can be stored in a database. During each verification process, based on the established Chinese character library, the first quantity of candidate Chinese characters and the pinyin of each candidate Chinese character can be obtained to generate the verification code, without having to establish a Chinese character library every time the verification code needs to be generated, and the candidate Chinese characters and their corresponding pinyin can be quickly obtained, thereby improving the efficiency of generating the verification code. In practical applications, there can be various ways to establish the Chinese character library, as long as the pinyin of each Chinese character can be obtained based on this Chinese character library. For example, by analyzing and counting the pinyin of each Chinese character, a Chinese character library is established.

[0066] Specifically, the set of Chinese characters corresponding to each pinyin can be counted first. Among them, the pinyin of all Chinese characters in the set of Chinese characters corresponding to each pinyin is this pinyin. For example, the Chinese characters corresponding to the pinyin zhi include but are not limited to: zhi, zhi, zhi, zhi; the Chinese characters corresponding to the pinyin shi include but are not limited to: shi, shi, shi, shi.

[0067] In practical applications, there may also be some polyphonic characters. For example, "le" has multiple pronunciations, namely "le" and "yue". Correspondingly, these characters can be removed in advance to obtain a Chinese character library with only multiple single-character pronunciations, thereby avoiding the influence of polyphonic characters on the verification result and improving the accuracy of verification.

[0068] When it is necessary to obtain candidate Chinese characters, multiple (the first quantity) pinyins can be randomly selected first, and then one Chinese character is randomly selected from the set of Chinese characters corresponding to each pinyin among these pinyins, and finally the first quantity of different candidate Chinese characters is obtained. It can be understood that the pinyin of each candidate Chinese character in the first quantity of candidate Chinese characters in this case is different.

[0069] Step S204, select the second quantity of candidate Chinese characters from the first quantity of candidate Chinese characters as verification Chinese characters, and randomly sort the pinyin of each verification Chinese character to obtain the target pinyin order.

[0070] During the specific implementation process, the second number of selected verification Chinese characters can be adjusted. It can be understood that the larger the value of the second number (the maximum is the first number - 1), the more pinyins there are in the target pinyin sequence, and the corresponding generated verification code is more difficult to crack, thereby improving the accuracy and reliability of the verification.

[0071] Step S206, selecting a target background image from a preset background image library.

[0072] In the specific implementation process, a plurality of background images (generally 400*400 images) with low interference and not pure color can be pre-set to form a background image library, and then the background image library can be stored in the database.

[0073] Step S208, display each Chinese character to be selected in the target background image to obtain a verification image.

[0074] In the specific implementation process, after obtaining the first number of Chinese characters to be selected from the Chinese character library, a background image can be randomly selected from the image library, and the background image can be used as a canvas to add each Chinese character to the background image in a preset format. For example, the characters can be pasted on the background image in a 50*50 size ratio without overlapping or going out of the border to generate a verification image. It can be understood that the pattern in the background image can interfere with the cracking program to recognize Chinese characters, thereby increasing the failure rate of cracking the verification code, thereby improving the accuracy and reliability of the verification.

[0075] Step S210, obtaining the first coordinate of each verification Chinese character in the verification graph.

[0076] In the specific implementation process, the coordinates of each candidate Chinese character in the target background image can be cached; then the mapping relationship between the coordinates of each candidate Chinese character in the background image, the candidate Chinese character, and the pinyin corresponding to the candidate Chinese character is stored in the same place in the database, so that they can be queried. In actual implementation, the coordinates of the verification Chinese character (equivalent to the first coordinate of each verification Chinese character in the verification image) can be selected from the cached coordinates of each candidate Chinese character in the target background image.

[0077] Step S212, sorting each first coordinate according to the target pinyin order to obtain the target coordinate order.

[0078] In the specific implementation process, each first coordinate can be sorted according to the target pinyin order according to the mapping relationship between the coordinates of each Chinese character to be selected in the background image, the Chinese character to be selected, and the pinyin corresponding to the Chinese character to be selected, to obtain the target coordinate order. Specifically, assuming that the coordinates of the four Chinese characters to be selected (such as "I", "want", "is", and "hand") added to the target background image are a, b, c, and d respectively; among them, the first coordinates of the three verification Chinese characters (such as "want", "is", and "hand") are b, c, and d respectively, so the above mapping relationship can correspond to "a-I-wo", "b-want-yao", "c-is-shi", and "d-hand-shou"; when each first coordinate is sorted according to the target pinyin order (such as "shou→yao→shi"), the target coordinate order (d→b→c) can be obtained.

[0079] In actual implementation, the target coordinate sequence and the target pinyin sequence can be stored in the database as correct "check points".

[0080] Step S214, generating a verification code according to the verification diagram and the pinyin sequence and sending it to the client.

[0081] During the specific implementation process, after selecting a second number of verification Chinese characters from the first number of candidate Chinese characters and generating the target pinyin sequence, the target pinyin sequence can also be added to the background image according to a preset format (for example, click on the Chinese characters in the image according to the target pinyin sequence) to generate the final verification code.

[0082] Step S216, obtaining the second coordinate and verification pinyin of each selected Chinese character selected by the user from the verification graph.

[0083] In the specific implementation process, the verification code can be returned to the client, wherein the verification code is generally provided with a prompt to click the Chinese characters in the picture according to the target pinyin sequence "". Specifically, it can be to click the Chinese characters in the picture according to the target pinyin sequence "shou→yao→shi".

[0084] When the user receives the verification code and sees the prompt, he can select Chinese characters for verification in the target pinyin order. When the user selects Chinese characters, the client captures the coordinate points of each selected Chinese character in the verification diagram (equivalent to the second coordinates mentioned above), and transmits the coordinate points clicked by the user to the server in the order of clicks. The server can map the relationship to find the pinyin corresponding to each coordinate point (equivalent to the verification pinyin mentioned above).

[0085] Step S218, obtaining a verification coordinate sequence and a verification pinyin sequence according to each second coordinate, each verification pinyin and the selection order of each selected Chinese character selected by the user.

[0086] In the specific implementation process, assume that the user sequentially selects the Chinese characters "要" (yào), "是" (shì), and "手" (shǒu) from the verification graph (equivalent to the selection order of each selected Chinese character by the user being "要 → 是 → 手"). The second coordinates of each selected Chinese character ("要", "是", "手") captured in the verification graph are b, c, and d respectively (equivalent to the verification coordinate order being "b → c → d"). Then, according to the mapping relationship, the verification pinyin "yao", "shi", and "shou" corresponding to each second coordinate can be obtained (equivalent to the verification pinyin order being "yao → shi → shou").

[0087] Step S220: Compare whether the target coordinate order is the same as the verification coordinate order, and whether the verification pinyin order is the same as the target pinyin order.

[0088] Step S222: If the target coordinate order is the same as the verification coordinate order, and the verification pinyin order is the same as the target pinyin order, determine that the user's verification is passed.

[0089] In the specific implementation process, the verification coordinate order and the verification pinyin order can be compared with the correct "verification points" stored in the database. Specifically, the verification coordinate order can be compared with the target coordinate order, and at the same time, the verification pinyin order can be compared with the target coordinate order. If the verification coordinate order is the same as the target coordinate order, and the verification pinyin order is the same as the target coordinate order, the verification is successful; otherwise, the verification fails.

[0090] For a better understanding of the above embodiments, the following can be used Figure 4 A schematic diagram of the verification code generation process provided by the embodiment of the present invention as shown below is used to illustrate the above embodiments.

[0091] From Figure 4 it can be seen that the client is communicatively connected to the server. When the server receives a user request for verification code configuration (equivalent to a verification code acquisition request) sent by the client, it can randomly select 4 combinations from the word library (each combination includes a single Chinese character and the pinyin corresponding to the single Chinese character), select 3 combinations from the 4 selected combinations, and randomly generate a target pinyin order.

[0092] The 4 combinations (equivalent to the first quantity of candidate Chinese characters and the pinyin of each candidate Chinese character) are pasted onto the background image according to a size ratio of 50 * 50 without overlapping and without going out of bounds. The coordinate points corresponding to the 3 selected combinations (equivalent to the first coordinates) are obtained, and they are sorted according to the target pinyin order to obtain the target coordinate order. The target pinyin order and the target coordinate order are used as verification points and stored in the database together. The expiration time can be set to 1 minute.

[0093] The pasted background image (equivalent to the verification image) and the randomly generated target pinyin sequence form a verification code and are returned to the client together. The verification code may include a prompt: Please click on the Chinese characters in the image in the target pinyin sequence "". When the user clicks on the Chinese characters, the client captures the user's click behavior, records the coordinate points (equivalent to the second coordinates), and sends the coordinate points and the click sequence of the coordinate points (equivalent to the verification coordinate sequence) to the server. After receiving the coordinate points, the server immediately queries the pinyin corresponding to the coordinate points through the coordinate points, and obtains the verification pinyin sequence based on the click sequence of the coordinate points. The click sequence of the coordinate points and the verification pinyin sequence are then compared with the check points. If the comparison is successful, the verification is returned to the client; if the comparison fails, the verification failure is returned to the client.

[0094] The verification code generation method provided in the above embodiment includes: obtaining a first number of Chinese characters to be selected and the pinyin of each Chinese character to be selected from a preset Chinese character library; wherein the Chinese character library includes multiple monophonic characters. This method uses pinyin as an index, counts the Chinese character sets corresponding to each pinyin, and clarifies polyphonic characters to establish a Chinese character library, so that the Chinese characters to be selected can be selected from the Chinese character library more quickly and accurately, thereby improving the efficiency and accuracy of verification code generation.

[0095] Furthermore, the method also includes: adding the candidate Chinese characters and the target pinyin sequence selected from the Chinese character library to the background image. This method combined with the pattern in the background image can interfere with the cracking program to recognize these Chinese characters, thereby increasing the failure rate of cracking the verification code, and then improving the accuracy and reliability of the verification.

[0096] Furthermore, the method also includes obtaining the second coordinate and verification pinyin of each selected Chinese character selected by the user from the verification graph; obtaining the verification coordinate sequence and verification pinyin sequence according to each second coordinate, each verification pinyin and the selection order of each selected Chinese character selected by the user; comparing whether the target coordinate sequence and the verification coordinate sequence are consistent, and whether the verification pinyin sequence is consistent with the target pinyin sequence; if the target coordinate sequence and the verification coordinate sequence are consistent, and the verification pinyin sequence is consistent with the target pinyin sequence, it is determined that the user verification has passed. This method allows the user to select Chinese characters according to the target pinyin sequence, and then performs verification according to the verification coordinate sequence and verification pinyin sequence obtained by the user's selection behavior, so that the verification code is not easy to be cracked, thereby having stronger security, and the verification operation is relatively convenient, which improves the user experience.

[0097] The embodiment of the present invention also provides a verification code generating device, which is arranged at a server end, and the server end is connected to a client end for communication, such as Figure 5As shown, the device includes: an acquisition module 50, which is used to obtain a first number of candidate Chinese characters and the pinyin of each candidate Chinese character if a verification code acquisition request is received from a client; a selection module 51, which is used to select a second number of candidate Chinese characters from the first number of candidate Chinese characters as verification Chinese characters, and randomly sort the pinyin of each verification Chinese character to obtain a target pinyin sequence; a verification module 52, which is used to generate a verification code based on the first number of candidate Chinese characters and the pinyin sequence and send it to the client, so that the user can verify by selecting each verification Chinese character from the candidate Chinese characters according to the target pinyin sequence according to the verification code.

[0098] The verification code generating device is arranged at a server end connected to the client end in communication, and the device comprises: if a verification code acquisition request is received from the client end, a second number of Chinese characters to be selected are selected from the first number of Chinese characters to be selected as verification Chinese characters, and the pinyin of each verification Chinese character is randomly sorted to obtain a target pinyin order; according to the first number of Chinese characters to be selected and the pinyin order, a verification code is generated and sent to the client end, so that the user can select each verification Chinese character from the Chinese characters to be selected according to the target pinyin order for verification according to the verification code.
