Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Please refer to fig. 1a, which is a flowchart illustrating an information verification method according to an embodiment of the present disclosure. The method can be applied to a server which can be a service device or a cluster formed by a plurality of service devices. Specifically, the method may comprise the steps of:
s101, in response to a verification information acquisition request sent by a terminal, determining a target text set from a text library.
In the embodiment of the application, the terminal can send the verification information acquisition request to the server, and the server can determine the target text set from the text library in response to the verification information acquisition request sent by the terminal. The terminal includes, but is not limited to, an intelligent terminal such as a smart phone, a tablet computer, a notebook computer, and a desktop computer. The authentication information acquisition request refers to a request that can be used to acquire authentication information, such as a page access request. The library of text may include a plurality of collections of text, such as lyrics, poems, or articles for each of a plurality of songs. The target set of text may be used to obtain verification information, the target set of text being any one of a plurality of sets of text.
In one embodiment, the server determines the target text set from the text library in such a manner that the server randomly selects one text set from the text library as the target text set. For example, the server may generate a random number within a preset value range, and determine a text set corresponding to the text ranked as the random number from the text set as a target text set.
S102, randomly selecting a first text from the target text set, and determining a second text associated with the first text.
Wherein the second text may be determined from the target text set and/or obtained by a search of a specified search engine.
In one embodiment, the server may determine a second text associated with the first text from the set of target texts. Wherein the second text may be any one of: the text of the next sentence of the first text, the text of the previous sentence of the first text, and other texts in the target text set except the first text, wherein the other texts are not the text of the next sentence of the first text and not the text of the previous sentence of the first text.
In one embodiment, the process of the server determining the second text associated with the first text from the target text set may be: if it is determined that the first text has a next sentence of text in the target text set, the server may determine the next sentence of text as a second text associated with the first text. In one embodiment, if it is determined that the first text does not have a next sentence text in the target text set, the server may determine a previous sentence text of the first text as the second text associated with the first text.
For example, the target text set is poem of quiet night thinking. The server may randomly select a first text from the poem, such as "please look for tomorrow at first", and may determine that the first text has a next sentence text "lower hometown", and thus the server may determine "lower hometown" as the second text associated with the first text.
Or, the process of the server determining the second text associated with the first text from the target text set may further be: if it is determined that the first text has a previous sentence of text in the target text set, the server may determine the previous sentence of text as a second text associated with the first text. In one embodiment, if it is determined that the first text does not have a previous sentence of text in the target text set, the server may determine a next sentence of text of the first text as the second text associated with the first text.
In one embodiment, the server may also search out the second text associated with the first text by specifying a search engine. In one embodiment, the server may search out information associated with the first text or information associated with the set of target texts as the second text associated with the first text by specifying a search engine. Wherein the associated information includes, but is not limited to, at least one of: identification information of an author of the target text set, a type of the target text set, and keywords of thought emotion expressed by the target text set.
For example, assume that the target text set is poem of thought at quiet night, and the first text is "look ahead and look bright moon". The server may search for identification information of an author of the poem of the quiet night thought by specifying a search engine, such as information of an era to which the author belongs, a name of the author, and/or a place of birth of the author, as the second text associated with the first text.
S103, drawing a first picture comprising the first text through an image processing library.
In this embodiment, the server may draw, through the image processing library, each word (a word includes one or more words) included in the first text in order in the first picture, so as to obtain the first picture including the first text. The first picture obtained in step S103 may be used as a common image verification code. For example, referring to fig. 1b, if the first text is "open-top-view moon", the content displayed on the common graphic verification code is "open-top-view moon". The image processing library may refer to a software library with a drawing function, such as a class library. In one embodiment, the image processing library may be a graphics class library (or may be a geometry library). As for the Java language, there may be Graphics2D class libraries.
In an embodiment, the server may further perform preprocessing on each word included in the first text to obtain preprocessed words, and sequentially draw the preprocessed words in the first picture. Wherein the pre-treatment process includes, but is not limited to, any of the following; adjusting the font, adjusting the font gradient and adjusting the font model.
In one embodiment, the server may also randomly add noise to the first picture to increase the difficulty of image recognition of the first picture. In one embodiment, the server may randomly add noise to the first picture according to a preset noise parameter. Wherein the noise parameter may include at least one of: noise distribution, noise number, noise shape.
S104, randomly selecting a preset number of words from a word bank, wherein each word in the preset number of words comprises one or more words.
The word stock may include a plurality of words, each of which may include one or more characters, including but not limited to strings of numbers, english words, or chinese characters. For example, the word stock is a Chinese word stock, the Chinese word stock includes a plurality of words, each of the plurality of words may include a Chinese character, and the server may randomly select 5 Chinese characters from the Chinese word stock, such as 5 primary Chinese characters "you", "o", "wood", "middle" and "money".
And S105, combining the second text with the preset number of words to obtain a third text.
The server combines the second text with the preset number of words to obtain the third text, which may be splicing the second text with the preset number of words by the server to obtain a spliced text serving as the third text. For example, the second text is "lower thinking of the country of the home country", and the preset number of words are "you", "o", "wood", "middle", "money". After the server splices the second texts with the preset number, a text "lower the head of the people in the hometown you joss money" after splicing processing can be obtained and used as a third text.
In an embodiment, the server may perform order adjustment on each word in the text after the concatenation processing by using a random sampling method or a random function, and obtain the text after the concatenation processing after the order adjustment as a third text. By adopting the method, the complexity of the third text can be improved. For example, the text after the splicing process is "lower the head of your hometown you middle money". After the server sequentially adjusts the text after the splicing processing by adopting the above method, the text after the splicing processing after the sequential adjustment, namely the text "you think low, middle town cash head and dead man", can be obtained as a third text.
In an embodiment, the random sampling mode may be a random playback-free sampling mode, that is, the server may perform sampling processing on each word in the text after the splicing processing in a random sampling playback-free mode to obtain a plurality of sampling results; and the server assembles the plurality of sampling results to obtain an assembly result which is used as the spliced text after the sequence adjustment. In one embodiment, the server assembling the plurality of sampling results may assemble the plurality of sampling results for the server in a sampling order. In one embodiment, the server may further call a random function to generate a corresponding random number for each word in the text after the concatenation processing; the server can sequence each word according to the sequence of the random numbers from large to small or the sequence from small to small, and can take the text formed by each word after the sequencing as the text after the splicing processing after the sequence adjustment.
And S106, randomly selecting a second picture from the image library, and drawing each word in the third text into the second picture at a random position through the image processing library.
The server may randomly select a second picture from the gallery, and draw each word in the third text to the second picture at a random position through the image processing gallery, thereby obtaining the second picture including each word in the third text. The second picture obtained in step S106 may be used as a click verification code. Wherein, the gallery may include a plurality of pictures. In one embodiment, the gallery may be a background gallery, which may include a plurality of background pictures.
For example, the third text is "you think of low, middle and rural maiden tree", referring to fig. 1c, the server may randomly select a picture shown in the left diagram of fig. 1c from the gallery. The server may draw each word in the third text at a random position in the picture shown in the left diagram of fig. 1c, so as to obtain the picture shown in the right diagram of fig. 1c, where the picture shown in the right diagram of fig. 1c includes "you", "xi", "e", "low", "middle", "home", "money", "head", "so", "wood".
In an embodiment, the server may further perform preprocessing on each word included in the third text to obtain preprocessed words, and sequentially draw the preprocessed words in the second picture. Wherein the pre-treatment process includes, but is not limited to, any of the following; adjusting the font, adjusting the font gradient and adjusting the font model.
In one embodiment, the server may also randomly add noise to the second picture to increase the difficulty of image recognition of the second picture. In one embodiment, the server may randomly add noise to the second picture using a preset noise parameter. Wherein the noise parameter may include at least one of: noise distribution, noise number, noise shape.
S107, obtaining verification information according to the first picture and the second picture, and returning the verification information to the terminal so that the terminal can execute verification operation according to the verification information.
In the embodiment of the application, the server may obtain the verification information according to the first picture and the second picture, and may return the verification information to the terminal, and the terminal may perform the verification operation according to the verification information. In one embodiment, the process of the terminal performing the verification operation according to the verification information may be that the terminal obtains the first picture and the second picture according to the verification information, and performs the verification operation according to the first picture and the second picture.
In one embodiment, the process of the server returning the authentication information to the terminal may be as follows: the server generates a target page including the verification information and a link address for accessing the target page, and returns the link address of the target page to the terminal. The terminal can send an access request for the target page to the server according to the link address of the target page. The server may return the target page to the terminal when receiving an access request to the link address of the target page by the terminal.
In one embodiment, the process of the server obtaining the authentication information according to the first picture and the second picture may generate the authentication information including the first picture and the second picture for the server. In one embodiment, the server may also count the text length of the second text and generate verification information including the text length of the second text, the first picture and the second picture.
In one embodiment, the server may receive verification result information returned by the terminal according to the verification information, where the verification result information is obtained after the terminal obtains the first picture and the second picture according to the verification information, and the verification result information includes position information of each word selected on the second picture according to the first picture; the server respectively calculates position deviation data between the position information of each word in the second text in the second picture and the position information of each selected word; and if the position deviation data is within the preset range, the server returns prompt information that the verification is passed to the terminal. The position information may be position coordinates. In one embodiment, if the position deviation data is within a preset range, the server may determine that the verification result information is verified. In one embodiment, the server may return a prompt message that the verification is passed to the terminal or perform the next service processing operation after determining that the verification result message is passed. In one embodiment, the server may store the position information of each word in the second text in the second picture or store the position information of each word in the second text in the second picture in a cache database.
For example, the first text is "look ahead at tomorrow", and the second text is "look ahead and hometown home town". Referring to fig. 1d, the terminal may obtain the picture shown in fig. 1b and the picture shown in the right diagram of fig. 1c according to the authentication information. The user may select a plurality of words from the picture shown in the right hand diagram of fig. 1c, according to the picture shown in fig. 1 b. The terminal can respond to the selection operation of the plurality of words and return verification result information to the server, wherein the verification result signal comprises the position information of each selected word. Or, when the verification information includes a text length of "low-heading hometown", which is 5 here, the terminal may count the number of the selected multiple words in response to the selection operation on the multiple words, and if the number reaches 5, may return verification result information to the server. The server can receive the verification result information and respectively calculate position deviation data of each word in the low-heading hometown image between the position information of the picture shown in the right picture of fig. 1c and the position information of each selected word; if the positional deviation data is within a preset range, it can be determined that the verification result information is verified. In one embodiment, the server may return a prompt to the terminal that the authentication is passed. In one embodiment, the server may perform the next business process operation.
In one embodiment, the server may also generate a random string. The server may generate authentication information including the random character string, the first picture, and the second picture, or generate authentication information including the random character string, a text length of the second text, the first picture, and the second picture. The server may store the random character string and the position information of each word in the second text in the second picture in association, for example, in a local or cache database. For example, the position coordinates of each word in the second text in the second picture are [ x ] in sequence1，y1]，[x2，y2]，…，[xn，yn]. The server may generate a random string, such as a Universally Unique Identifier (UUID). The random string may be a 32-bit random string, and accordingly, the UUID may also be a 32-bit UUID. Can be used forAnd taking the UUID as a key, and the position coordinates of each word in the second text in the second picture as a value, and storing the value into a cache database, such as a redis cache database, in a correlated manner. In one embodiment, a buffer duration, such as 5 minutes, may be set for the random string.
In an embodiment, when the verification information includes the random character string, the verification result information may carry the random character string, and the server may perform the step of calculating the position deviation data between the position information of each word in the second text in the second picture and the position information of each selected word when the server queries the position information of each word in the second text in the second picture corresponding to the random character string in a local or cache database.
In one embodiment, the server may calculate, by means of ordered matching, position deviation data between the position information of each word in the second text in the second picture and the position information of each selected word, respectively, for the position information. Specifically, the process of the server calculating the position deviation data between the position information of each word in the second text in the second picture and the position information of each selected word may be that the server calculates the position deviation data between a first word in each word in the second text and a second word in each selected word, and an arrangement order of the first word is the same as a selection order of the second word. The first word is any one of the words in the second text. Correspondingly, the second word is the word with the same sequence as the first word in the selected words. For example, the first word is a word arranged in the 5 th order in the second text, and correspondingly, the second word is a word selected from the selected words and arranged in the 5 th order, that is, the second word is the selected 5 th word.
In one embodiment, the server may calculate, by using an unordered matching method for the position information, position deviation data between the position information of each word in the second text in the second picture and the position information of each selected word respectively. Specifically, the process of the server calculating the position deviation data between the position information of each word in the second text in the second picture and the position information of each selected word may be that if each word in the second text matches each selected word, the server calculates the position deviation data between a third word in the second text and a fourth word in each selected word, where the third word is the same as the fourth word. The third word is any one of the words in the second text. Correspondingly, the fourth word is the same word as the third word in the selected words. Compared with the former method, the latter method is more complex, but the situation that the user selects words according to different sequences is considered, so that the later method is adopted to find corresponding words to calculate the position deviation data, and the verification success rate can be improved.
In one embodiment, the server may further return a prompt message to the terminal, where the prompt message may be used to prompt the user to select a second text associated with the first text included in the first picture from the second picture. For example, the prompt message may be: please select the next poem of "lifting the head and looking at the moon".
As can be seen, in the embodiment shown in fig. 1a, the server may determine the target text set from the text library in response to the verification information obtaining request sent by the terminal; the server can randomly select a first text from the target text set, determine a second text associated with the first text, and draw a first picture comprising the first text through an image processing library; the server can randomly select a preset number of words from a word bank, and combine the second text with the preset number of words to obtain a third text, so that each word in the third text is drawn into a second picture at a random position; the server can obtain the verification information according to the first picture and the second picture and return the verification information to the terminal, so that the terminal can execute verification operation according to the verification information, and the safety of the verification process is improved.
Please refer to fig. 2, which is a flowchart illustrating another information verification method according to an embodiment of the present disclosure. The method can be applied to a server which can be a service device or a cluster formed by a plurality of service devices. Specifically, the method may comprise the steps of:
