In the (10) observation meeting, 'the verification server will automatically generate a problem and provide the problem to the user, r. According to the user's answer, the user will answer the computer. Or human. At present, the most common and convenient CAPTCHA test method is the verification method using the eye shape verification code. a undertakes 'current graphics verification code technology is more commonly used in the field of web services, = users (personal households) _ - terminal devices rely on, want to access special::::::::^^ The server will randomly select a plurality of characters, such as: text, number 201228326 words and symbols, and arrange the characters to verify the password, and generate a graphic verification code according to the verification password, please refer to Figure 1. It is shown that the verification code generated by the verification server is "90429628", and the figure shown in Fig. 1 is the verification code generated by the verification server, and the verification ship is generating the verification code! After that, the graphic verification code is transmitted to a terminal device, and the user is required to input the verification password "9〇429628" according to the graphic verification code, so that the terminal device can return to the verification feeding device. After the verification password "9〇429628", the specific data is accessed by the verification program of the inspection service 15. In the past, since the technique of image recognition has not yet matured, the computer (i.e., the aforementioned terminal device) cannot automatically recognize the content of the graphic verification code 1 and cannot automatically pass the verification program of the verification server. However, with the advancement of image recognition technology, various kinds of malicious programs with image recognition functions (such as: RQbQts, Spiral (10) top) are more and more powerful, and their image recognition is correct. The sex is much higher than before, and therefore some people who are unscrupulous are trying to use the above-mentioned malicious programs, and want the terminal device to automatically pass the verification procedure of the ride. #验证船财 produces the graphic verification code 1, and after the concurrent _ verification code is transmitted to the terminal device, the terminal device automatically records the graphic verification code 藉 by the malicious program, and analyzes the _ verification^ The content of 1 '嗣' can be used by the terminal device to automatically input the graphic verification code 1 _ 容 ', and the shed clerk verifies the 杂 n misf(10), and accesses the specific data 'to make the graphic verification code! The verification mechanism cannot effectively distinguish the computer from human beings, but it is not ideal. In addition, at present, the big _ 2 will have a large number of threat access actions, such as downloading files in large quantities, and it will also load the ship II connected to the test server. 201228326 In view of the above _, in order to prevent malicious programs from automatically completing the verification process, the industry changes the way the verification server generates the _ verification code, so as to complicate the graphics verification, for example, the verification of the ship is generating _ verification rhyme, the verification Adding a lot of noise, noise lines or #景, even processing such as image twisting to improve the complexity of the graphics verification code. In the figure j, the verification ship β generates the verification code 1 and the partial characters of the face code are partially overlapped, so that the image of the malicious program cannot be positive. The content of the verification password is Reduce, the success rate of the program, and the ability to resist some of the malicious programs, so that malicious programs can not function properly, _ to avoid the occurrence of the above problems 'but this - the practice will be greatly reduced _ verification code 丨The readability makes it impossible for the user (human user) to easily recognize the content of the graphic verification code, which seriously reduces the recognition accuracy rate of the user, and increases the possibility of the user recognizing the error. In this way, when the money recognizes the wrong material of the wrong person, the verification ship must re-listen to the line program 're-selling the money-__彡 verification code, and send it to the final Wei'. The _, the burden of more serious verification of the ship 'is very unsatisfactory. Therefore, 'how to improve the number of conventional graphics verification codes _, in order to prevent the automatic identification of the image recognition technology of the malicious studio without reducing the user identification accuracy rate, is the case for the present invention. Question. SUMMARY OF THE INVENTION In view of the many problems mentioned above, the inventors have made long-term efforts and experiments to "finally develop and design a method for generating dynamic graphic verification codes by using the character arrangement method of the present invention" to prevent unscrupulous malicious programs from automatically completing the verification program. And reduce the difficulty of 201228326 = the listener, listen to the repeated Wei mine, the negative purpose of the singularity, the system provides a dynamic picture of the kind of marriage character paste method - the method is applied to a verification server, when After verifying the client-access request (such as the web page read request and the floor 2 download request), the verification feeder can randomly generate N characters (such as: number, etc.). - verify the password, and the verification device can fetch = (four), the first character of the code to the gamma character, the Qing Cheng - touch style = map, where the system is less than Ν; 嗣, the verification clothing The device can operate the verification password ^ the second character to the third character + the first character to form a continuous pattern of character maps, the initial value of t X is not greater than γ; thereafter, the verification server will be defective The value is one, And repeat the above steps, (10) into the character pattern of the next-mirror pattern; until the example ^ verification server can verify the (10) character of the (4) to the ke = character 'to form - the style of the 齢 bundle style Finally, the verification ship will generate the __ verification code on the other side, and transmit the Wei state graphic verification code to the miscellaneous device so that the (4) (4) _ verification code can be moved in the predetermined time. The contents of each character map are displayed in sequence. In this way, since the dynamic graph=verification code only displays (four) sub-characters in the same time, the malicious program method completely analyzes the entire password _ volume, so the verification process cannot be completed automatically' not only effectively solves the problem. It can reduce the possibility of users identifying errors. The other purpose of this month is that the verification server retrieves the verification password from the == to the γth character. When the initial pattern is used, the character of the initial style is checked. In the figure, the position 201228326 adjacent to the first character is added with a dot mark 'so that the user can recognize the starting point of the dynamic graphic verification code, and improve the readability of the dynamic graphic verification code. A further object of the present invention is that the verification server captures the first character to the yth of the verification password to form a character _ of the initial pattern, which is adjacent to the character pattern of the initial pattern. The position of the first character is added—the starting point blank area' so that the user can recognize the starting point of the dynamic graphic verification code to avoid user identification errors. Another object of the present invention is that when the verification ship generates the character map of the ending style, the character of the ending style is added, and the end mark is added adjacent to the last-clear character, and the reading user can recognize (4) The end point of the _-shaped verification code to improve the readability of the dynamic graphic verification code. The re-purpose of the present invention is that when the character map of the end pattern is generated, the end point "area" is added to the position pattern of the end pattern in the character pattern of the end pattern, so that the user The end point of the dynamic graphic verification code can be easily recognized, and the user can be prevented from recognizing errors and the like. For the sake of the examination committee, the purpose, structure and efficacy of the present invention can be further understood and understood. The detailed description is as follows: [Embodiment] In the inventor's research and development process in the related fields such as the long-term verification system, the inventor found that the current complicated and low-level graphic verification code cannot prevent most of the knowledge functions, €, Yicai, *Small test shirt Xiao people carefully shadow analysis ^ graphics verification code _ Rong 'to prevent malicious programs to automatically complete the verification process ^ verification code is complicated, such as · increase a lot of noise, noise lines, distortion graphics, etc., will = 201228326 into graphics The readability of the verification code is greatly reduced, which seriously affects the user's recognition accuracy rate. Most of the current operators want to improve the graphics verification code to Solving the above problems, but still has not got a proper solution. In view of this, the inventor thinks and uses the arrangement of characters to generate dynamic graphic verification code, so as to reach the saga without detracting from the readable graphics code (4). The invention is a method for generating a dynamic graphic verification code by using a character arrangement method, as shown in FIG. 2, in the first preferred embodiment of the present invention, the method is applied to the verification servo. On the device 20, a terminal device 21 is connected to the verification device 2 through the network 22 (internet or zone_road). The verification server 20 is not limited to having only verification function. The verification server 2 can also have the functions of a web page feeder or a slot server, or the verification ship 2 can be connected with a webpage servo H or a file server, when the terminal The device 21 passes the verification servo II 2G _ to verify the process, and Weihu (4) 2G allows the terminal device 21 to access the information on the fine-page ship or the file server (eg, webpage, building case, etc.) Easy in the art The variation of the invention is not limited to the technical scope to be protected by the present invention. In the preferred embodiment, the user connects to the network 22' through the browsing Is of the terminal device 21 and wants to After the verification by the verification server 2〇, the terminal device 21 downloads the file (or reads the web page), in which case the terminal device 21 transmits an access to the verification server 20. The request, the access request is a slot download request (or web page read request) 'to indicate that the terminal device wants to download or read the web page after verification by the verification server 20. In this case, when the verification server 20 receives the access request from the terminal device 21, please refer to the figures 2 to 4, the verification server 2 generates a dynamic graphic verification according to the following steps: 201228326 The code is such that the verification server 20 can perform the verification process subsequently: (300) the verification server 20 randomly generates a verification password consisting of N characters (eg, characters, numbers, symbols, etc.). In the embodiment, N = 6, so the verification password is 4 packets. 6 characters are included. Please refer to FIG. 4, the content of the verification password 4 is "A2B4C9"; (301) the verification server 20 retrieves the first character to the gamma character of the verification password 4, Forming a frame of the initial pattern of the character map 41, where γ is less than N, and in the preferred embodiment, 'Y=3', so the verification feeder 2 will take the first character of the verification code 4 to The third character, that is, "Α2β", to form the initial pattern of the character map 41; (302) the verification server 20 retrieves the first character of the verification password 4 to form, the continued pattern of the word two 42 = initial value No more than Υ. In the preferred embodiment, the initial value of χ is i, so the verification server 20 retrieves the second character to the fourth character of the bribe password 4, that is, "2B4" to form Character of continuous pattern Figure 42; (Net) The verification feeder 20 accumulates the value of X so that the value of X becomes 2, and the ship feeder takes the 1+th character of the verification password 4 to The first γ + χ child pays 'that is the third character to the fifth character: "", to form another frame continuous pattern of characters Figure 43; (3 〇 4) the verification feeder 20 will X The value of the value is incremented by one, so that the value of X becomes 3. At this time, Η ' X=3 ' and Χ + γ = 6, that is, χ + γ = Ν, in this case, the verification ^ 20 will perform the verification. The mth character of the password 4 to the Υ+Χ 固子付', the 4th character to the 6th character: "4 (:9), to form a character of the 201228326 end-of-frame style picture 44; and (305) The verification server 2 is configured to generate the dynamic frame verification code into a dynamic frame verification code. In the preferred embodiment, the dynamic graphics verification code is -GIF (Graphics lnterchange). The case of 'gif' is small in size and relatively clear in imaging. In fact, it is a kind of compressed money, which is encoded by LZW compression algorithm, which can effectively reduce the time for the transmission of the standard on the network. One of the image formats used for network transmission. After the verification ship n 2G completes the production process of the secret verification code verification code, the dynamic verification code is transmitted to the device 21 so that the dynamic graphic verification code can be in the silent state _ In the preferred embodiment, the verification ship 20 is in the process of producing a dynamic graphic verification code according to the character figure 41. Word 42, character map 43, character map 44, character map 43, character map 42 _ sequence to create a shape verification code, so, #动动_ verification code sequentially displays each of the character maps 41, 42, 43 The contents of 44 will show the effect of moving the marquee left and right. However, the present invention is not limited thereto. The verification ship is said to be producing a green graphic verification code, and the dynamic graphic verification code may be produced only in the order of the character picture 4, the character picture 43, and the character picture 44. The effect of the phase # can also be achieved by causing the dynamic graphics verification to display the respective character maps 4, 42, 43, and 44. According to the technology of the present invention, after receiving the dynamic graphics verification code through the terminal device, the characters of the verification password 4 can be viewed and the password (4) of the authentication password 4 can be recognized within the predetermined time.魄, the verification password 4 is input to the terminal device 21, so that the terminal device 21 can transfer the verification password 4 input by the user to 201228326 to the verification ship (4), and ride the final position 21 to successfully pass the verification bribe. ϋ 2G _ miscellaneous. Lin Facai, because the dynamic graphic verification code* produced by the verification word benefit 20 will display the verification f code 4 at the same time, and only some characters will be displayed. Therefore, there are unscrupulous people who want to use malicious The image is carried out by the ship, and the content of the verification password 4 is parsed by means of taking and dividing the image. Since the image of the image is only partially contained, it is impossible to completely correct the whole test _ 4 _, so the financial effect Prevent malicious problems. Furthermore, 'because the present invention can effectively prevent the pre-"solution method, therefore, when the verification ship 2 is making the characters 4|, 42, 43, 44', it is not necessary to add too many defects or Noise lines, there is no need to deal with the distortion of the graphics, etc. 'So, the _ thief of the low side of the cake, reduce the number of people who can identify the wrong one can reduce the loss of the stalker, verify the 祠 service Γ ^ must The situation of re-executing the verification program 'significantly reduces the load on the verification server. In addition, in the present invention, the verification buffer 20 may add some features when generating the initial pattern and the ending character map to improve the readability of the __ verification code! In the embodiment, as shown in the second and fifth figures, the verification commission 2G is at the left end of the character pattern of the initial pattern, that is, adjacent to: the position of the second character "A" is added - the starting point mark 5G, For example: - the font is smaller, the character is not limited to this invention. In the design of the handle of the feeding suit E 20 according to the present invention, the style of the Wei touch mark can also be changed, for example: The style of the mark 50 is changed to other _, which can be used by those skilled in the art. And the father's should be covered in the patents of the present invention. In addition, the reference to the fifth riding show 'the test (four) 2 〇 can also be generated in the silk pattern 12 201228326, Figure 44a, in the end of the character map drag, adjacent to the last character 9" position added At the end point mark 5 丨, the end point mark μ is also a "*" character. Thereby, when the user views the dynamic graphic verification mother, the user can more clearly grasp the start point and the end point of the dynamic graphic verification code, and can smoothly determine the content of the dynamic graphic verification. Further, please refer to FIGS. 2 and 6. In the third preferred embodiment of the present invention, the verification ship 20 is in the process of capturing the verification password 4! When the character to the third character 'to form the character pattern 41b of the initial pattern, a starting point blank area 60 of a predetermined width may be added to the position of the character pattern 41b of the initial pattern adjacent to the first character "A". And setting the width of the starting blank area 6〇 to the width of one character, and the verification server 2 is capturing the 4th character to the 6th character of the verification password 4 to form a character pattern of the ending style At 44b, a position blank area is added to the position adjacent to the last character "9" in the character pattern 44b of the end pattern, and the width of the end blank area 61 is also set to a character width, so that the user The start point and the end point of the dynamic graphics verification code can be identified by the start blank area 60 and the end blank area 61, thereby effectively avoiding the problem of the user identification error 4.
