The present invention relates to a file / folder recovery system and method through P2P, and more particularly, a plurality of unspecified P2P using / providing terminals are connected to a P2P recovery service central server through an internet network, and thus, a plurality of unspecified P2P using / providing terminals. The present invention relates to a file / folder recovery system and method through P2P that realizes a program for performing the recovery upon request of this recovery.

 In general, the operating system or various program files of a computer system may be physically or logically damaged. It can also be deleted or corrupted by virus programs. Therefore, in the event of a failure of a computer system, a recovery medium is separately prepared to recover and use the computer system.

 In Korean Patent Application Publication No. 2001-0070803 <Recovery and Backup System and Method>, the same operating system and recovery software as the user's computer system are backed up in a removable flash memory to meet the requirements of the user, and a failure occurs. There is proposed a system and method for recovering by using the flash memory, and the Republic of Korea Patent Publication No. 2003-0032558 <How to recover the failure of the computer system online / offline> of the computer system online and offline In order to recover from a failure, a method of recovering a failure by storing system information of a computer used in a used computer and comparing the separately stored system information when a failure occurs in the used computer system has been proposed.

 However, the Republic of Korea Patent Publication No. 2001-0070803 is not always easy to back up to meet the recovery requirements, and if the lost flash memory is not able to proceed with the recovery operation at all, and a plurality of constant network configuration There is also the hassle of having to have a separate flash memory to recover a computer system. In addition, the Republic of Korea Patent Publication No. 2003-0032558 has a problem that occupies a large part of the computer system space because the system information must be stored separately in the computer system being used, and at the same time several computer systems online If it is necessary to recover, it takes a lot of time due to the load of the network and there is a problem that can not be restored normally.

 In case of the above cases, operating systems such as Windows XP provide a service called <System Restoration>, but even in this case, it is possible to recover each commercial program by storing system information separately in the computer system space. There is no. In general, in order to recover a single program, the user may recover the program at the time of restoring the entire program.

 Also, I want to recover only one file in case one file / folder is damaged. Currently, there is no method other than downloading and overwriting the Internet.

 For example, mfc70.dll, mfc70d.dll, msvcp70.dll, msvcr70.dll, msvcr70d.dll, msvcr80.dll, etc.

As a Microsoft C ++ Runtime Library, when you install program A, install program B, and then delete A from the system, files shared with B can be deleted.

 Therefore, even if the operating system and various program files of the computer system installed in the computer are lost due to user's mistake of changing or deleting, aging of the drive, software crash, virus, etc. There is a need for a recovery system that can be easily restored to a desired point in time.

 In brief, the hash code is a 4-byte code for authenticating data, which requires the creation of a hash table. The hash table can be constructed by performing XOR and RSHIFT operations on hexadecimal '0xEDB88320' for each index value from 0 to 255 in 256 4-byte arrays. The hash code is calculated by twisting all the contents of the data by starting with the hexadecimal '0xFFFFFFFF' and retrieving the result of XOR operation with each byte value of the data in the pre-created hash table. Therefore, the hash code is an operation value that changes the result value only if the elements of the data are changed slightly. The fact that the two hash codes are the same means that the two data are equal to the probability of <1 / 2.4 billion>.

 Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

 In each figure, each reference numeral for explaining the structure of the figure is numbered according to the number and order of a figure. Duplicate numbers, even if duplicated, are given different reference numerals.

Depending on the nature of the drawings, subscripts may be attached before the reference numerals, in the present invention, when the drawings are flowcharts as shown in FIG.

 The P2P recovery service application according to the present invention is referred to as a REPAIR FILE program hereinafter. In addition, P2P using / providing terminal generally refers to a personal computer (PC), it is obvious that it can be applied to any number of changes, such as PDA, HPC, mobile phone.

FIG. 10 is a diagram illustrating the overall configuration of a general computer network system in which a communication network is configured on the Internet among the configurations of a file / folder recovery system via P2P online according to the present invention.

11 is a diagram showing a detailed configuration of an intermediary server in a file folder recovery system via P2P online according to the present invention.

 P2P recovery service central server (1002, 1104) stores the member information, login information and IP address information, billing information, recovery source file information, recovery source file usage information, recovery source file provision information, etc. of the P2P service subscribers, and Interworking with P2P mediation service unit 1106, member management module 1108, and billing server 1114, which smoothly induces users to connect to each other by utilizing the above-described information. And a billing client 1110 for processing billing for the P2P recovery service, and a billing server 1114 for providing billing and payment means.

Based on the above configuration, in FIG. 10, the P2P recovery service central server 1002 is a P2P using / providing terminal 1006, 1008, 1010, 1012, 1014, 1016 and the Internet 1004. It is coming true. The P2P recovery service central server 1002 is configured as described above with reference to FIG. 11, and the P2P mediation service unit (P2P mediation service unit) is requested by the P2P using / providing terminals 1006, 1008, 1010, 1012, 1014, and 1016. P1P using providing terminal (1006, 1008, 1010, 1012, 1014, 1016) registered from 1106 to create an environment to act as a server and the user to his own P2P using providing terminal (1006, 1008, 1010, 1012) , 1014, 1016) provides a P2P recovery service application that can control all functions.

 1 is a flowchart illustrating a file recovery method of a P2P recovery service according to the present invention.

Referring to FIG. 1, a system and method for recovering a file / folder through P2P according to the present invention undergo the following process.

 After the user connects to the central server of the P2P recovery service (1002) through the P2P using / providing terminals (1006, 1008, 1010, 1012, 1014, 1016) (S102), follow the instructions of the P2P recovery service central server to join the membership. After downloading the REPAIR FILE program, install the REPAIR FILE program to the P2P using / providing terminal (S104).

 When the user installs the program and executes it to log in (S106), the user's P2P use / provision terminal 1006 accesses the P2P recovery service central server 1002 and then uses / provides the P2P of another user who is logged in. The IPs of the terminals 1008, 1010, 1012, 1014, and 1016 are received from the P2P recovery service central server 1002, and connected to the corresponding IPs (S108).

 When the user has a file to be recovered in his P2P using / providing terminal 1006, the user selects the file using a mouse (S110) and then drags & drops to the REPAIR FILE program (S112) or the file to be recovered. If it is already deleted, create a text file (S110), modify the name and extension of the text file with the corresponding file name and extension name and drag and drop the file to the REPAIR FILE program to recover the file. (S112)

 The REPAIR FILE program, which has received the user's recovery intention, generates a hash code of the file (S114), and then P2P of another user who is logged in with the name and extension of the file, the hash code, and the detailed settings of the user. The recovery source file is found by the user / provider terminal 1008, 1010, 1012, 1014, 1016 (S108) and displayed on the user's P2P user / provider terminal 1006.

 The user recovers the file by selecting the displayed file (S118). When the recovery of the file is terminated and there are no additional files to recover, the REPAIR FILE program terminates the recovery of the recovered file.

 2 is a flowchart illustrating a system recovery method of a P2P recovery service according to the present invention. A detailed description of FIG. 2 will be provided after the file recovery embodiments according to the flowchart of FIG. 1 are described with reference to FIGS. 4A, 4B, 4C, and 5.

 3A, 3B and 3C show an initial execution screen of the REPAIR FILE program according to the present invention.

Hereinafter, the control items and the GUI required for realizing the present invention will be described with reference to FIGS. 3A, 3B, and 3C. Compared with the gist of the present invention, the parts that are relatively insignificant are simply introduced and passed through.

 Of course, this is a kind of illustration, of course, it does not limit the scope of the present invention.

 When the user executes the REPAIR FILE program through his / her P2P using / providing terminal 1006, basically, FIG. 3A is displayed on the P2P using / providing terminal 1006 of the user.

 Looking at the items shown in FIG. 3A one by one, the system recovery 302 creates a recovery point at a point in time when the user wants the main programs in the user's P2P using / providing terminal 1006 while using the REPAIR FILE program, and then the main If the files of the programs are damaged, it provides a function to restore the main program files to the point of time when the recovery point was made through the recovery point.

 Setting 304 will be described with reference to FIG. 6. Referring to the item shown in FIG. 6, the folder 602 in the setting 304 provides a function of setting a path of the storage folder 608 for storing the recovered file, and the shared folder 610 is used by another user. The P2P using / providing terminal 1008, 1010, 1012, 1014, 1016 provides a function for setting a folder for sharing a recovery source file to be provided when a user requests a recovery source file from the user, and the recovery designated folder 612 is provided. Hash code is generated periodically for the main program items designated by the user, so that a quick and smooth recovery operation can be performed when the files of the main program are damaged.

 The recovery server 604 limits the number of files that can be restored at the same time and the number of recovery source files that can be provided at the same time, so that the REPAIR FILE program utilizes the hardware resources of the user's P2P using / providing terminal 1006. By controlling the user himself to prevent the situation that the processing speed of the P2P using / providing terminal 1006 is slow or other programs are not performed smoothly.

 Again, returning to FIG. 3A, the help 306 provides assistance to users who are not yet familiar with the REPAIR FILE program in various ways, from the tutorial mode to the usage of the REPAIR FILE program.

 The restore list 308 is a window showing a list of files / folders currently restored by the user, and when the restore list 308 icon is clicked, the restoration list 326 and the completion list 328 as shown in Fig. 3b. A tab will appear, allowing the user to see the files / folders currently being recovered and the files / folders that have been recovered.

 The explorer 310 has the same function as the explorer used in a general Windows operating system, and the source list 312 is a P2P user / provider terminal 1006, 1008, 1010, 1012, 1014, 1016 of another user. A list of source files being provided from the P2P use / provision terminal 1006 is shown. The information is provided to the user, divided into file name, size, recovery time, and points.

 The reliability 314 means a value calculated by the REPAIR FILE program based on a condition for searching for a recovery source file when the user recovers a file through the REPAIR FILE program. The larger the value is, the higher the probability that the user wants the file should be, and the conditions for searching may be given a file name, file size, hash code, file path comparison, etc., but this is largely related to the main purpose of the present invention. There is no such information, so detailed description is omitted.

 The user recommendation 316 is a search sorting function that displays search results in the order most recommended by other users among the searched recovery source files. The file / folder name 318 is a search condition only for the name of the file / folder, apart from user recommendation and reliability values.

 The file map 320 serves to adjust the number of search results shown to the user.

 The 500 point 322 is an item representing the point value held by the current user. The point is deducted when the user restores the file / folder, and the point increases when the recovery source file is provided to another user. This point deduction and increase is inducing users to share more recovery source files through interaction with each other.

 The charging 324 provides a method of making a payment using a credit card, ARS, mobile phone authentication, cash back (ex. OK Cash Bag), etc., if the current user's point does not have enough value to recover a file / folder. The main role is to complement the business aspect of a company that provides a file / folder recovery system and method through P2P according to the present invention.

 4A, 4B, and 4C are diagrams illustrating an example of recovering a file by changing a screen according to the flowchart of FIG. 1 according to the file recovery according to the present invention. However, the general description of file downloads and logins is omitted.

 Figure 4a shows that the recovery source files are set by the user after dragging and dropping the file with the REPAIR FILE program to recover the msvcp70.dll (402) file (Microsoft C ++ Runtime Library file) that was damaged when the user installed / deleted the program. The screen is displayed on the user's P2P using / providing terminal 1006 centering on a file to be restored based on a reliability value.

 In addition to the same file 404 as the file that the user wants to recover, the recovery source file can also search for files 406 and 408 having different file names according to the user's search setting value. You can also get updates.

 FIG. 4B is a screen displaying detailed information 410 of a corresponding file displayed when the user clicks on the same file 404 once.

 FIG. 4C is a screen displaying information on a list of files being restored and a recovery rate when the user selects a file 404 having the same name as a recovery source file as a recovery source file. When recovery of the recovery file is completed, the completed recovery file is stored in the storage folder 608 set above.

 FIG. 5 illustrates a case in which the user drags and drops a folder 502 rather than a file. In this case, unlike a case of dragging and dropping a file, a simple selection window 504 is displayed on the screen as a pop-up, and the corresponding folder is directly displayed. It will be restored in the manner selected by the user after asking the user's intention about whether or not to restore or to manage the system in terms of system recovery by designating a recovery folder 612.

 In the above, the method of recovering files and folders by the file / folder recovery system and method through the present invention P2P has been described with several drawings.

 In addition, the present invention provides a method for creating a recovery point (backup) quickly and easily at the desired time point with the main program installed in the user's P2P using / providing terminal, along with a method for recovering the file / folder immediately and return the main program to the recovery point The method and the system are also presented.

 Hereinafter, a description will be given of a system recovery method of a P2P recovery service according to the present invention through FIG.

 2 is a flowchart illustrating a system recovery method of a P2P recovery service according to the present invention.

2, the system recovery method through P2P according to the present invention goes through the following process. However, common parts that may be referred to in FIG. 1, such as connection to the P2P recovery service central server 1002, membership registration, login, and installation of the REPAIR FILE program, will be omitted in the following description. Also,

7A, 7B, 7C, 7D, 8A, 8B, 8C, 9A, 9B, and 9C illustrate an embodiment of a system recovery method of a P2P recovery service according to the present invention. Reference is made to the drawings in the order shown in FIG. 2.

 When the user selects the system recovery 302 of the REPAIR FILE program (S202), the screen shown in FIG. 7A is displayed on the user's P2P using / providing terminal 1006, and the REPAIR FILE program is a task for performing system recovery. Proceed to S204.

 At this stage, the REPAIR FILE program asks the user what they want to do, creating a recovery point according to the user's choice (S206, 702), restoring the main program to the previous recovery point (S216, 704), and removing the recovery point. Perform the operation of (S226, 706).

 When the user selects a recovery point creation operation (S206, 702), the screen shown in Fig. 7B is displayed on the user's P2P using / providing terminal 1006. This step is a step of selecting a program folder for creating a recovery point (S208), in which the list information of the recovery designated folder 612 set in FIG. 6 is displayed together (712). Select the Next (716) button, select the Back (714) button to return to the previous selection process, or select the Cancel (718) button to cancel the system recovery process.

 If the user selects a folder to create a recovery point in the above step and selects a next button 716, the user's P2P user / provider terminal 1006 displays the screen shown in FIG. 7C. This step is a step of writing a description of the recovery point (S210), in which a word or phrase describing a recovery point in time is entered. In addition to the word or phrase written by the user, the current date and time information may be additionally stored in the recovery point information. The user can select the next 724 button if the selection is correct, select the back 722 button to return to the previous selection process, or select the cancel 726 button to cancel the system recovery process.

 If the next button 724 is selected in step S210, the REPAIR FILE program performs a step S212 of generating a hash code of the files in the folder for the folder selected by the user in step S208.

 When the operation of step S212 is completed, the screen shown in FIG. 7B is displayed on the user's P2P using / providing terminal 1006. This step is a step (S214) in which the creation of the recovery point is completed, the description 728 of the corresponding recovery time point written by the user in step S210 and the information on the folder selected by the user in step S208 are displayed. The user confirms the above information and presses the OK button 732, thereby completing the recovery point creation operation (S206, 702) in system recovery.

 When the user selects the main program recovery (S216, 704) operation to the previous time point in step S204 of FIG. 2, the screen shown in FIG. 8A is displayed on the user's P2P using / providing terminal 1006. This step is a step (S218) of selecting a recovery point previously made through step S206 to step S214, and the recovery point list information created by the user so far is displayed together. Select the point you want to restore, select the next (804) button if you are correct, select the back (803) button to return to the previous selection, or cancel (806) if you want to cancel the system recovery process. Simply select the button.

 In the above step, if the recovery point to be restored is selected and the next button 806 is selected, the screen illustrated in FIG. 8B is displayed on the user's P2P using / providing terminal 1006. This step is a step in which the detailed information of the recovery point is displayed in detail (S220). The user selects a system folder to be recovered from the recovery point time, and then, if the user wants to recover to the recovery point, the next step (814). If you want to go back to the previous selection process, select the back button 812. If you want to cancel the system recovery process, select the cancel button 816.

 If the user selects the next button (814) in the step (S220), the REPAIR FILE program is a P2P use / providing terminal 1006 of another user connected through the IP address received from the P2P recovery service central server 1002. 1008, 1010, 1012, 1014, and 1016, the folder name, file name, file size, hash code, and the like are compared to complete the recovery only when the user sets the criteria.

 When the step S220 is completed, the screen shown in FIG. 8C is displayed on the user's P2P using / providing terminal 1006. This step is a step (S224) where the recovery to the recovery point selected by the user is completed. In this step, when the user presses the OK button 820, the main program recovery operations S216 and 704 are completed as an advantage point in system recovery.

 When the user selects the recovery point elimination (S226, 706) operation in step S204 of FIG. 2, the screen illustrated in FIG. 9A is displayed on the user's P2P using / providing terminal 1006. This step is to create a program that does not need to be restored in the future (steps deleted) or another recovery point for the program folder from the previously created recovery points through step S206 to step S214. If so, in step S228, the recovery point list information created by the user is displayed together with the recovery point list. (902) The user selects a recovery point to delete, and if the selection is correct, the next ( 904, select the button, select the Back button (903) if you want to go back to the previous selection process, or select the Cancel (906) button if you want to cancel the system recovery process.

 If the recovery point to be deleted is selected in the above step and the next button 906 is selected, the screen illustrated in FIG. 9B is displayed on the user's P2P using / providing terminal 1006. This step is to display the detailed information of the recovery point in detail (S230), the user checks the detailed information of the recovery point, if you want to delete the recovery point, select the OK button (912), the recovery point If you want to end the deletion process, select the Cancel (910) button.

 When the operation (S230) is completed, the screen shown in FIG. 9C is displayed on the user's P2P using / providing terminal 1006. This step is the step of deleting the recovery point is completed (S232), by pressing the OK button 916, the recovery point deletion (S226, 706) operation in the system recovery is terminated.

 As described above, in the present invention, when there is an error in an operating system or a word editor of an unspecified user, the user does not need to recover an error file through the program provider or by using a mass storage such as a CD. You can easily recover from the same file.

 As described above, in the present invention, when there is an error in an operating system or a word editor of an unspecified user, the Internet does not have to go through the program provider or use a mass storage such as a CD without the trouble of recovering an error file. You can easily recover from the same file of another user connected to the.

In addition, after the user generates a hash code for a large amount of data, the user prepares only a space capable of storing a very small capacity unlike the conventional backup method by backing up only the data of the generated hash code to his or her mass storage hard disk. Just do it. Therefore, anybody can use it easily from the hardware difficulties of the existing backup, and always use the Internet P2P to return the desired programs and files to the previous state.
