The present invention relates to a secret bulletin board device and method on the Internet, and more particularly to a secret bulletin board device and method on the Internet by applying the Internet Web-related rules and technologies in a computer connected to the Internet and a web server connected to the Internet.

In recent years, the use of the Internet (INTERNET) connecting networks around the world has become commonplace. Internet users provide data such as e-mails, files, movies, and voices from anywhere in the world. There are various servers on the Internet that provide information. Among these servers, web server provides various services such as text, voice, picture, moving picture, multimedia service and file transfer. In addition, a technique that is difficult to perform in a web server is a technique for processing information by executing a server application program running on the server, and providing the processed information to Internet users in general.

Meanwhile, the Internet bulletin board is a place on the Internet where Internet users publish information or files in order to share information and files with numerous Internet users. Anyone of the Internet users can read or download the public information or files. Most Internet bulletin boards are open to all Internet users, and membership boards are designed to allow members to read information or download files.

In other words, the Internet bulletin board is not a place for one person but a public place on the Internet for several people.

On the other hand, an e-mail is a place for only one person and can send information such as a letter or a file to the person over the Internet.

To use e-mail, you need your own e-mail address that is distinct from other people, and there are many Internet service providers that provide these e-mail addresses.

These e-mail services mainly provide e-mail services by signing up as a member, but since most companies limit the e-mail usage of members, Internet users have difficulty in sending a large file by e-mail. Due to the exposure, receiving unsolicited e-mails such as advertisements has been increasing, resulting in an unsatisfactory problem with e-mail use. In addition, there are situations in which e-mail is sent but not received, and it takes a long time from sending an e-mail to receiving.

Therefore, Internet users who use the e-mail address the original purpose of fast delivery of information and files, overcome the problems of capacity limitations when using existing e-mail, and also have no e-mail address or do not know the e-mail address. There is an urgent need for a service that can deliver information and files quickly and accurately.

The present invention has been made to solve the above problems, the object of the present invention is to register a file of information and unlimited capacity with a password on the bulletin board on the Internet by providing an Internet secret bulletin board to read only through the password It solves the problem of limiting the e-mail capacity to Internet users, and the sender can ensure the accurate delivery of the data by confirming that the data is registered on the bulletin board, and users who do not have an e-mail address or do not know the e-mail address The present invention provides a device and a method for providing a confidential bulletin board on the Internet to exchange information and files through the Internet.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a block diagram showing a secret bulletin board device on the Internet according to the present invention.

This device is connected to the general Internet 100, the secret bulletin board server 110 performs a secret bulletin board service and the wired or wirelessly connected to the Internet to register a post on a secret bulletin board or a terminal 120 for reading posts based on When the post is registered on the secret bulletin board, the mobile communication terminal 142 of the recipient who is notified of the registration facts and the sender's mobile terminal 141 notified of the reading fact when the post is read are connected to the Internet and notified. It is composed of a mobile communication company server 130 for processing a request and a mobile communication base station 131 connected to the mobile service provider server to transmit a radio signal.

The flow of the present invention will be described with such a device.

The person sending the data accesses the secret bulletin board server 110 through a terminal device 121 connected to the Internet, and registers a post such as information and attachments with the password in the secret bulletin board. At this time, a large attachment can be registered.

The secret bulletin board 110 registers data in a database, notifies the registration fact by email of the recipient of the data, and also notifies the registration fact to the mobile communication terminal 142 terminal 142 of the recipient of the data. The registration notification data is sent to the mobile telecommunication company server 130.

The mobile service provider server 130 sends registration notification data to the mobile communication base station 131 where the data receiver is located, and the mobile communication base station 131 wirelessly to the mobile communication terminal 142 of the data receiver. Notify you of registration.

The person who is notified of the registration fact by an e-mail or a mobile communication terminal accesses the secret bulletin board server 110 through the terminal device 122 and inputs a password set for the security of the data to read the data. The secret bulletin board server 110 notifies the fact that the data is read to the e-mail or mobile communication terminal 141 of the sender.

This allows Internet users to overcome the problems of fast delivery of information and files and limited email capacity, as well as faster and more accurate delivery of information and files using secret bulletin boards even for Internet users without or without an email address. .

2 is a detailed configuration diagram of a terminal device and a secret bulletin board server according to the present invention.

The terminal device 210 is a means for searching for information on the Internet in connection with the Internet, and the secret bulletin board server 220 is a device for storing data or transmitting the searched data.

The input device 216 and the output device 217 are connected to the terminal device 210.

The input device 216 includes a keyboard and a mouse for inputting various data.

The output device 217 includes various devices such as a monitor to display the content searched by the browser 210.

The terminal device 210 is connected to the Internet 200 through a network interface card 211. The network interface card 211 is a wired modem or a wireless modem or a network adapter for connecting to the Internet network.

In addition, the terminal device 210 constitutes an operating system 214 connected to the network interface card 211 through a driver 212 and a communication protocol 213 operating thereby. The operating system 214 causes each device to operate such that the device processes the content input through the network interface card 211.

The internet communication protocol 213 refers to all protocols used on the Internet, and is required to receive a service through the Internet.

The terminal device 210 is operated by the operating system 214 and includes a browser 215 capable of internet access by the communication protocol 213. Browser 215 is a tool used to retrieve hypermedia documents.

HyperMedia Text is a document described in HyperText Markup Language (HTML). Hypertext Markup Language (HTML) is a hypermedia document authoring language that browsers, browsers, must recognize and interpret.

The browser 215 searches for all documents on the Internet and displays the contents of the documents on the screen for the user to view.

Meanwhile, the secret bulletin board server 220 operates and is configured like the network interface card 211, the driver 212, the operating system 214, and the communication protocol unit 213 of the terminal device. That is, the secret bulletin board server 220 is connected to the Internet 200 through the network interface card 221, and the communication system operating by the operating system 224 connected to the network interface card 221 through the driver 222. Configure the protocol 223.

The operating system 224 causes each device to operate such that the device processes the content input through the network interface card 221.

In addition, the secret bulletin board server 220 includes a web server 225 that is operated by the operating system 224 and operated by the communication protocol 223.

The web server 225 searches for and transmits the data requested by the browser 215 in the web page storage device 226 according to the HyperText Transfer Protocol (HTTP).

The hypertext transfer protocol (HTTP) defines a communication protocol between the browser 215 and the web server 225.

The secret bulletin board server 220 is connected to the server application 230 between the web server 225 and the database management unit 231.

The server application 230 controls the database manager 231 for managing a database such as registration, search, viewing, and deletion of the bulletin board database 232, and a file manager 233 for managing file storage, output, deletion, and the like. Control, the mail management unit 235 for sending e-mail, password confirmation, and a program written to notify the message to the mobile communication terminal. The server application 230 is a program executed in the server, and is an application program for performing a function that the web server 230 cannot perform. The server application writes the result of the work as a document in the form of web page to the web server, and the web server outputs the web page to the user's browser.

Server applications include Common Gateway Interface (CGI) programs and Internet Server Application Program Interface (ISAPI) programs.

CGI is loaded into the server system's memory at every request from the browser to perform and remove tasks. Therefore, if there are many request connections, a large number of CGI programs are loaded into memory, which consumes a lot of server system memory. The solution to this problem is the ISAPI program. An ISAPI program is a dynamic link library (DLL). Once loaded into memory, other requests are processed using the already loaded program. Therefore, the server system has the advantage of using less memory, but there is a problem that the stability is lower than the CGI program.

In order to send an e-mail, the server application program 230 performing the above function is made by requesting an e-mail to the e-mail management unit 235 dedicated to sending an e-mail.

On the other hand, the secret bulletin board server 120, the database management unit 231 is connected between the server application 230 and the bulletin board database 232.

The database manager 231 operates by the operating system 224 and processes the data requested by the server application 230 with reference to the bulletin board database 232.

The bulletin board database 232 is a place for storing data requested by the database manager 231.

In addition, the secret bulletin board server 220 is connected to the file management unit 233 between the server application 230 and the file storage device 234. The file manager 233 is operated by the operating system 224, and stores the file requested by the server application 230 in the file storage device 234 or outputs the file storage device 234 with reference. The file storage device 234 is a place for storing attachments of a post.

3 is an example of an initial screen shown in a browser of a terminal device connected to a secret bulletin board server through the Internet.

The secret bulletin board servers 110 and 220 establish a domain name, which is a name of an internet site, after accessing the internet 100 and 200 through the connection unit 221. When a user inputs a domain name that is an internet address of the secret bulletin board servers 110 and 220 using the terminals 120 and 210, the secret bulletin board servers 110 and 220 output the web page data of FIG. 3 to the user's browser 215.

The user may register data using the registration means 330 or quickly find a desired data using the search means 320.

The user can see the posts (311, 312, 312, 314, 415) in the registered post list 310 to know the data sent to them, and can view the posts using the page moving means (316, 317).

4 is an example of a screen for registering a post on a secret bulletin board.

When the user selects the registration means 330 of FIG. 3, the bulletin board servers 110 and 220 output the registration web page of FIG. 4 to the user's browser.

The user is subject (401), password (402), recipient (403), sender (404), recipient email address (405), sender email address (406), recipient mobile number (407), sender A person mobile communication number 408, a letter content 409, an attached file name 410, and the like are selectively inputted, and the verification means 420 is selected to register the post in the secret bulletin board.

5 is an example of contents notified by e-mail.

When the post is registered, the secret bulletin board server (110,220) checks whether the recipient's e-mail address (504) exists, writes a letter (506) with reference to the entry entered when registering the post, and the recipient's e-mail address (504) You will be notified by email that the post has been registered. If there is an attachment, the link code 510 linking the attachment is included in the contents of the email.

In other words, by keeping the attached file on the bulletin board server and providing the link code to find the attached file, it is possible to deliver a large amount of files without being affected by the email capacity limit of the recipient. By removing, information and files can be delivered quickly.

6 is an example of a screen notified to a mobile communication terminal.

When the data is registered, the secret bulletin board server checks whether there is a phone number 408 of the recipient's mobile communication terminal 600, creates a message 601 by referring to the entry entered when registering the post, and the recipient Notifies the mobile communication terminal 600 of the.

On the other hand, even if the recipient does not have an e-mail address, mobile communication terminal, etc., the sender informs the recipient of the domain name, registration number and password of the secret bulletin board server by wire, such as a telephone. By connecting to the secret bulletin board server as a device to view posts, there is an advantage that even a person without an email address can exchange information and files through a secret bulletin board device on the Internet.

7 is an example of a screen for searching for a post on a secret bulletin board server.

When the user selects the search means 330 of FIG. 3, the secret bulletin board servers 110 and 220 output the search web page 700 of FIG. 7 to the user's browser.

The user can register (701), Subject (702), Recipient (703), Recipient's email address (704), Recipient's mobile number (705), Sender (706), Sender's email address ( 707, the sender's mobile communication number (708), the registration date (709), and optionally enter the selection means 710 to request a data search can be found quickly required posts.

8 is an example of a password request screen for showing a post.

When the user views posts 311, 312, 312, 314 and 415 in the post list 310 of FIG. 3 that is output to the user's browser as the initial screen or a search result, the user briefly displays the registered information 810 of the selected post and checks the password. The password 820 request web page 800 is output to the user's browser.

The user enters a password and selects the verification means 830 to transmit the password to the secret bulletin board server.

9 is an example of a screen showing the post content of the bulletin board.

If it is determined that the password is normal through the process of Figure 8, the secret bulletin board server outputs the detailed information web page 900 for the post to the user's browser.

Details include registration number (901), registration date (902), sender (903), sender email address (904), recipient (905), recipient email address (906), subject (907), and letter content. (908), the attachment means (90) and the like, and the editing means for modifying the post content (910), the deleting means for deleting the post (903), the list means 920 to end the post view and view the list of posts By making it easier for users to use.

The operation of the present invention configured as described above will be described in detail with reference to a flowchart.

10 is a flowchart illustrating a registration process of a secret bulletin board.

When the user selects the registration means 330 of FIG. 3 to apply for registration (S1001), the web server 225 outputs the registration web page 400 to the user's browser 215 (S1002).

The user inputs the contents to each item of the registration web page 400 (S1003), selects the verification means 420, and requests registration to the web server 225 (S1004).

The web server 225 runs the server application 230. The server application 230 checks the input contents of the required items such as the title, the recipient, the sender, the contents of the letter, and determines whether the post can be registered (S1005).

If the check result is not registered, an error message is written and output to the web server 225, and the server application 230 is terminated. The web server 225 outputs an error message to the user's browser (S1009).

On the other hand, if registration is possible, it is required to store the attached file in the file management unit 233. The file management unit stores the file in the file storage device 234 and outputs the stored location information to the server application 230. The server application 230 sends the registration data including the location information of the attachment to the database management unit 231 to request the post registration. The database manager 231 stores the registration data in the bulletin board database 232, and outputs the result to the server application 230 (S1006).

The server application 230 performs a notification processing for notifying the recipient of the registration result (S1007). The notification process will be described in detail with reference to FIG.

After the notification processing is performed, a registration completion message is generated and output to the web server 225, and the server application 230 is terminated. The web server 225 terminates the post registration by outputting the registration completion message to the user's browser (S1008).

11 is a detailed flowchart of the notification processing of FIG. 10.

The server application 230 checks whether there is a recipient's mobile communication terminal telephone number in the registration data (S1101).

If there is a telephone number, a summary message is created with reference to the registration data and the message is notified to the mobile communication terminal of the recipient (S1102).

In addition, it is checked whether there is an e-mail address of a recipient (S1103).

If there is no e-mail address, the notification processing is terminated (S1110). If there is an e-mail address, an e-mail letter is created with reference to the registration data (S1104), and it is checked whether there is an attachment in the registration data (S1105).

If there is an attachment, a link code for connecting the attachment is created (S1106), and the link code is added to the contents of the email letter (S1107). An example in which a link code is added to an email content may be viewed as a link code 510 of FIG. 5.

The server application 230 requests the mail management unit 235 to send the letter written by email (S1108), and terminates the notification process (S1110).

12 is a flowchart illustrating a search process of a secret bulletin board.

When the user selects the search means 320 of FIG. 3 (S1201), the web server 225 outputs the search web page 700 to the user's browser 215 (S1202).

The user inputs a search condition into the search web page 700 (S1203), selects the verification means 710, and requests a post search from the web server 225 (S1204).

The web server 225 runs the server application 230. The server application 230 finds a post that meets the search condition in the bulletin board database 232 to the database manager 231 and outputs the search result data to the server application 230 (S1205).

The server application 230 writes the search result data as the color result web page, outputs it to the web server 225, and terminates the server application (S1206).

The web server 225 outputs the search result web page to the user's browser 215 (S1207), and ends the search (S1210).

13 is a flowchart illustrating a process of viewing the post contents of the secret bulletin board.

When the user selects a post that he / she wants to view in the post list 310 of FIG. 3 (S1301), the web server 225 shows the brief information about the post, and displays a web page that requires a password for the post. Output to step 215 (S1302).

An example of this is shown in FIG. 8.

The user enters a password and selects the verification means 830 to transmit the password data to the web server 225 (S1303).

The web server 225 runs the server application 230. The server application 230 performs a password verification process to determine whether the password of the post is normal (S1304). The password verification process will be described in detail with reference to FIG. 14.

If the password is treated as an error, the server application 230 writes an error message and outputs it to the web server 225 and terminates the server application 230. The web server 215 outputs an error message to the user's browser 215 (S1309).

On the other hand, if the password is processed correctly, the server application 230 creates a web page showing the post content and outputs to the web server 225 (S1306) and terminates the server application 230.

The web server 225 outputs the received web page to the user's browser 215 (S1310). An example output to the user's browser 215 is shown in FIG. 9.

14 is a detailed flowchart of the password verification process of FIG. 13.

Internet users who do not have permission to view posts must know their passwords in order to view others' posts. Therefore, you must change the password until the password is correct and request reading. There are hacking programs that make this iteration easier. For the security of data from these hacking programs, if a password error occurs several times in the process of verifying the password, the security function of the data registered in the bulletin board is used by using a method that treats the password error regardless of whether the password is correct or incorrect. Can be improved.

For the security of the posts, the allowable time for requesting information is set to 1 minute, and an example of three password error times will be described. That is, if a password error occurs more than 3 times, all input passwords are treated as an error, and if there is no request for password confirmation for more than 1 minute, the password can be checked through the normal password verification process for 3 times and the data can be read if the password is correct. This is a password confirmation process to give permission.

When the server application 230 requests the post information from the database manager 231 to check the password data transmitted by the user, the database manager 231 records a record having the information of the post requested from the bulletin board database 232. Read and output to the server application 230 (S1402).

The record structure of the post information will be described in detail with reference to FIG. 17.

The server application 230 compares the data of the password field with the password transmitted by the user to the received post record and determines whether the password is correct (S1402).

If the password is incorrect, the data value of the error recovery field is increased, and the information request time field is changed to the current time to request the database manager 231 to modify the data. The database manager 231 modifies the fields of the corresponding records of the bulletin board database 232 (S1408).

The server application 230 processes the verification result as a password error (S1409).

On the other hand, if the password is correct, it is checked whether the one minute has elapsed from the latest information request time by referring to the data of the information request time field (S1403).

If the password is requested again within 1 minute, check whether the number of errors is three or more times (S1404).

If the error count is three or more times, the data value of the error count field is increased, and the information request time field is changed to the current time to request the database manager 231 to correct the data. The database manager 231 modifies the fields of the corresponding records of the bulletin board database 232 (S1408).

The server application 230 processes the verification result as a password error (S1409).

On the other hand, if the password is correct, the last reading request time is more than 1 minute, or if the password error count is less than three times, the database management unit 231 is required to modify the data in the error count field to zero. The database manager 231 modifies the error count field data of the record to 0 in the bulletin board database 232 (S1405).

The server application 230 performs a notification process for notifying the sender of the post to the sender of the post (S1406).

The server application 230 processes the password verification result as a normal password (S1407).

The notification process of notifying the sender will be described in detail with reference to FIG. 15.

This password verification process is a password security technology that enhances the security of the post. In this example, the allowable time for requesting information is 1 minute and the number of errors is 3 times. However, various changes may be made depending on the situation.

FIG. 15 is a detailed flowchart of a notification processing process shown in FIG. 14.

When a post is read, the process of notifying the person who registered the post is read. The server application 230 checks whether there is a sender's mobile communication terminal telephone number in the post information (S1501).

If there is a telephone number, a summary message is created with reference to the registration data, and the message is notified to the sender's mobile communication terminal (S1502).

In addition, it is checked whether the sender's email address exists (S1503).

If there is no e-mail address, the notification processing is terminated (S1110). If there is an e-mail address, an e-mail letter is created with reference to registration data (S1504).

The server application 230 requests the mail management unit 235 to send the letter written by email (S1505), and terminates the notification process (S1510).

16 is a flowchart illustrating a secret bulletin board data deletion process.

As shown in FIG. 9, if the user obtains the deletion means 930 from the web page showing the details of the post to the user, and the user selects the deletion means 930 and transmits the deletion data to the web server (S1601), the web server 215 drives the server application 230.

When the server application 230 requests the database manager 231 to delete the post specified in the deleted data (S1602), the database manager 231 deletes the corresponding post from the bulletin board database 232.

The server application 230 creates a deletion result web page and transmits it to the web server 225 (S1603) and ends the program.

The web server 225 completes the deletion of the post by outputting the deletion result to the user's browser 215 (S1604).

17 is an example of a record structure of a bulletin board database.

The minimum unit for storing information in a database is a field, and a set of fields of various types is a record. The database is configured to be in the form of a collection of records 1700. Posts posted on the secret bulletin board is managed by a database, each post is stored in the form of a record (1700).

The record 1700 of the bulletin board database 232 includes fields for storing contents input by a post registrant and fields for managing posts.

The registration number 1701 field records the order in which data is registered to distinguish posts.

The registration date and time 1702 field records the date and time the post was registered.

The Number of Views 1703 field records the number of times a post has been viewed.
