INSTRUCTIONS: [Technical field to which the invention pertains] The present invention relates to a method for restricting the use of harmful multimedia files (such as a harmful multimedia file), and more specifically to be used as intended. The animation of electricity money «times, through the search - pre-constructed harmful dynamic DB, one-by-user blacklist, and / or - user-by-user email address list, enabling faster use - harmless animation (such as regeneration) And enabling the use of a harmful animation; and for encrypting harmful animation files registered in the blacklist, so that the harmful animation files cannot be used in other user computers that do not have the system according to the invention installed, thereby Avoid ways to redistribute harmful animation files. [Prior Art] A well-known method widely used to limit the use of harmful multimedia files in a user's computer is implemented in the following manner: • A specific provider or system with 2 sets of harmful multimedia files distributed over the Internet and From the harmful multimedia (the talent case draws the feature value to construct a harmful multimedia db, the harmful multimedia DB system constructed by Yanhai is installed in a user's computer, and when it decides to use it in the user's computer, the file system corresponds to When installing a file registered in a harmful multimedia lang, 'the use of the file can be restricted. According to this idiom- 〇 because only one DB is constructed for harmful multimedia files distributed over the Internet, there is one that is not distributed on the Internet. Or it is difficult to collect the problem that the Japanese-language media file can still be used without restriction. Another common method for blocking harmful animations (for example, in Korean Patent No. 5 Main Book No. 2 (2) One method disclosed is to search for the harmful content in the Internet on the network of 127849.doc 200837601. All or part of the harmful, the basics, the basics, the DB, the transmission of the ', ', the construction of a harmful internal money from the desire to pass - the user's computer, in use or part of the compilation and / or regeneration (executed ) the broadcast of all the harmful content of the db, the hash value of the file and the content of the harmful content, stop the transmission of the value of the comparison, and when the broadcast corresponds to the harmful internal knowledge technology, each case and / or delete the broadcast. According to this - the user computer is reproduced by the driver-execution program (for example) =: a hash value of the regenerative private, and 1 (4) when the case is 'f To retrieve the value of the value in the right-handed-special value from the file, to compare the hash value of the captured with the miscellaneous content in the harmful content 〇3 to the harmful content D”==, and determine the file Technology 'even if a normal animation in a harmless animation:!.: outside 'according to the waiting time - the predetermined time period P + , it must always wait for luck h hang 'in a user computer to reproduce the animation of the investigation of the second More harmful animations in the harmful animation slot, and the regeneration frequency of the Epoch-Files is much higher than Therefore, the regenerative frequency of each roll of WJ 'U. Because of the animation. /. An animation file is 'very inefficient to search the entire harmful according to the conventional technology, when using a harmful animation file to force the end, such as using a broadcast case - Method of moving, or deleting a file. When a service form of a program that has a function of 1 is implemented, the main use is: := The resistance is based on the commercial method + the party that is forced to end a corresponding program in this case' Usually, 'When 1 the authentication procedure has been successfully completed—guardian mode or supervisor mode) to check access to the records of the harmful files 127849.doc 200837601, a harmful animation is allowed. However, in this case, Verification - Harmful animation standard, but the harmful animation slot is not: The user's computer is deleted and remains in place. Therefore, when the unremoved and retained harmful animation files are transferred to a computer that is not equipped with the -# animation blocking function by disc copying, etc., the harmful files can be used in any case. Therefore there is a limit to even the - (four) specimen-hazard dynamic archives that actively block redistribution. SUMMARY OF THE INVENTION Therefore, the present invention has solved the problems that the domain has occurred in the prior art, and the present invention provides a verification method for blocking a use in a file when it corresponds to a harmful multimedia case.

[Embodiment] Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. The entire construction of the method according to an exemplary embodiment of the present invention will be described in the accompanying paragraph. (d) An exemplary embodiment of the present invention, there is a method for restricting the use of a harmful multimedia file, the method comprising: - harmful multimedia DB construction step 1 , # verifiable via network 127849.doc 200837601 Whether each multimedia file corresponds to a harmful multimedia file; extracting the identifier and meta information to identify the harmful multimedia slot; ^ storing the captured identifier and meta information in a server DB; a multimedia DB transmission step 200, which can transmit a harmful multimedia DB constructed in the harmful multimedia db construction step to a user computer; a user-by-user blacklist construction step 300, which can search for multimedia files in the user's computer, Comparing the searched multimedia file with the harmful multimedia DB and constructing a black list, which is a list of the harmful multimedia files; and a harmful multimedia file use blocking step 400, which is intended to be used by the user in the user's computer a multimedia file is sequentially compared with a user-by-user blacklist and a harmful multimedia DB; and when the multimedia file corresponds to harmful In the case of a multimedia file, the use of the multimedia file can be blocked, wherein at least one of the user-by-user blacklist construction step 300 and the harmful multimedia file use blocking step includes a harmful multimedia file encryption step 5, which will delete the harmful multimedia file. It can be encrypted and stored in the user's computer, so that harmful multimedia slots can be prevented from being distributed or used by different users. Preferably, as shown in FIG. 1B, the method may further comprise a harmful multimedia case decryption/regeneration step 600, after the harmful multimedia slot encryption step 500, when encrypting the harmful multimedia file to be heavy in a manager mode The system can 'decrypt and reproduce encrypted harmful multimedia files, which have passed an authentication procedure of the user's computer. More preferably, as shown in FIG. 2, the method may further include: a user-by-user email address list construction step 3〇〇w, which can construct an email by searching for one of the multimedia files in the user's computer. Address Qing 127849.doc -12 - 200837601 List of harmless multimedia files; and user-by-user blacklist construction v, 300, &&&& multimedia files use instantaneous permission step 4〇〇W' I Before the user blacklist construction step, when the user's email address list is searched for, and the multimedia slot file is determined to be a harmless multimedia file, a multimedia file used in the user's computer is immediately allowed. Exemplary embodiments of each step included in the method according to the present invention will be described in more detail with reference to Figures 3 to 5. First, the computer software program (which may be a general component through which the user computer actually implements the method of the present invention) is provided to the user's computer. In the step 1 of constructing a harmful multimedia DB by the @server (from the perspective of the user's computer - the remote system) operated by the provider (which constructs and provides the harmful multimedia DB to the user's computer), the servo The device can automatically collect or manually collect the harmful multimedia files circulating through the Internet, establish (or fetch) the verification data from the collected multimedia files, and check the verification data to construct the harmful multimedia DB. ,As shown in Figure 3. In the case of 2, a key value of each file stored in the harmful multimedia DB includes the message extract value retrieved from the file, and an identifier is taken from an appropriate file area to minimize collision and achieve correct identification. . A message is a special value of a fixed length obtained by applying a one-way hash function to a given input value, and is a sum check code that can be used to check whether an original file has been tampered with. . When an identifier of a file, MD5, and grain core (10) are widely known as a message digest function, the present invention can use the message excerpt value, wherein the hash function is 127849.doc 200837601 It can be used in the present invention. In addition to the method by which the server directly collects the through-net case, as described above, the method according to the present invention may include a method of a special program according to the second method A of the present invention (for example, -PC) When executing, the special program can be created from the multimedia file stored in the user's user's memory, that is, the multimedia file (ie, the multimedia rights file of the harmful media standard) (for example, fetching). Verification data of the symbol or meta information, and instantly through the Internet: pass: verification data, and the server can verify the verification data, thereby verifying whether the multimedia file in the computer that is potentially determined to be a harmless multimedia file is actually It is harmless, as shown in Figure 3. When the multimedia file classified as _ harmless multimedia broadcast through the harmful multimedia in the user's computer is verified as a case, the server can update the current harmful multimedia DB to 可7 guilty. The method may be implemented by additionally including a step of recording additional data of harmful multimedia broadcasts taken from the user's computer in harmful multimedia in order to facilitate each method in accordance with an embodiment of the present invention. Update the harmful multimedia DB. That is, this step may include a file license and verification data transmission step 700, and - harmful multimedia DB and user computer update step, as shown in Figure 5. In (4) use license ^ verify data transmission In step 700, the user computer can generate authentication data from the multimedia file of the harmless multimedia file in the user computer, and transmit the generated verification data to the server. The harmful multimedia Db and the user computer update step. In step 8〇〇, the server can verify the received test 127849.doc -14· 200837601 α bedding, when corresponding to the verification data When the media file system determines to be a harmless multimedia file, it updates the email address list of the user's computer. When a multimedia file corresponding to the verification data is determined to be a harmful multimedia broadcast, the corresponding information is added to the harmful The multimedia db updates the harmful multimedia DB and transmits the updated harmful multimedia device 6 to the user computer so that the updated harmful multimedia DB can be downloaded by the user computer. Therefore, even if the Internet is not transmitted through the Internet The circulating harmful multimedia files can be recorded in the harmful multimedia DB. ζ According to an exemplary embodiment of the present invention, as shown in FIG. 2, a blacklist (BL) and an email address list (WL) are constructed according to each user computer. Steps 300 and 3 can be implemented, for example, in a cache scheme. Here, the t-list (BL) represents the /monthly list of harmful multimedia broadcasts present on the user's computer, and the email address list (WL) a list of harmless multimedia files present on the user's computer, and preferably such lists are formed in a data structure of a hash table Based on the fact that the number of harmful multimedia files is relatively large compared to the total number of multimedia files existing in a user I computer, the present invention provides a blacklist for constructing harmful multimedia files; an electronic device for constructing harmless multimedia files a list of mail addresses; and a method of using these lists before searching for harmful multimedia DBs. • As shown in Figures 4 and 5, when a multimedia file is used for a user's computer, first, an email address list is executed ( WL) search step (see reference number "400W" in Figure 5). In this case, when the multimedia file system decides to be a harmless multimedia file included in the email address list (WL), the multimedia file can be immediately permitted. And terminate the harmful multimedia file 127849.doc -15· 200837601 Use the blocking program to enable faster use of the harmless multimedia slot.

When the target file has been determined to be a harmful multimedia file, the target file can be blocked and, more preferably, the blocking history can be recorded in the user's computer - so it can be provided - more accurate and efficient harmful multimedia The standard uses the blocking function. In addition, when the multimedia file is determined to be a harmful multimedia building in the harmful multimedia DB search step 43 of the last step, the 'block user can use the file' and at the same time, the program will branch to the branch point "F", as shown in Figure 5, because the multimedia file is not encrypted, so that the multimedia file will undergo a separate file encryption step. At the same time, as shown in FIG. 5, 'preferably, after the file encryption step 500 of encrypting the harmful multimedia files', the information of the harmful multimedia files is newly added to the blacklist (BL) existing in the user's computer, and updated. A blacklist of blacklists (BL) adds a step 55 to be executable, so that when the harmful multimedia file is used again, the use of the harmful multimedia slot can be blocked. Although Figures 4 and 5 show the case where the email address list search step 4〇〇w and the list search step 4H) are continuously performed, the two steps can be performed as follows: 127849.doc -16 - 200837601 Execution. In more detail with respect to the file encryption step, preferably, after a multimedia file stored in the user's computer is determined to be a harmful multimedia slot, a file system filter driver (FSFD) is used. The multimedia file is encrypted in a core mode in which the drive controls a drive of a slot system. More preferably, the corresponding multimedia file can be an encrypted file in a key scheme, so that in a computer not equipped with the system (including a program) for implementing the present invention, it is impossible to decrypt the corresponding multimedia file. In this case, since the encrypted slot cannot be used in a computer that is not equipped with a system, it is impossible to use the encrypted file even if the encrypted slot has been transmitted to a different computer, thereby avoiding the corresponding file redistribution. At the same time, in a computer on which a system embodying the method of the present invention has been installed, usage rights are provided through an authentication code. In this case, when the user who has obtained the usage right (the guardian (for example, the parent) who has logged in in the administrator mode) attempts to use an encrypted harmful multimedia file, it is preferable to additionally perform an instant decryption regeneration step. 6〇〇, as shown in Figure 2, so that the user can make a fine (4) case. The A function blocks the use of a harmful multimedia file when a teenager boy or girl attempts to use a harmful multi-girl file and records the blocked history. Therefore, when the guardian of the parent checks the history of the obstruction, it can be identified which one of the broadcasts is blocked for its harmful reasons. This identification procedure can be achieved by instant decryption, where decryption is performed in a core mode using FSFD, which is similar to the drive that controls the file system in the slot encryption step. According to another non-exclusive embodiment of the present invention, when a harmful media file is encrypted, for example, a buoy. The identification code can be used to determine the step in which a predetermined identification code of a p can be inserted into an encrypted file. If the multimedia broadcast is already in use, it is not used. At the same time, the identification code can be displayed in this way, and the identification code is determined by the unit (not recognized on the line of the letter: harmful more than two ^^ cases. Preferably, multiple, Tian', 纟 restricted use harmful The multimedia file is here (4), although::::: can be inserted - harmful multimedia files. Segment transmission, but the identification and correction system is divided into multiple segments, and the bearer B, the 7° early can determine the transmission of harmful multimedia files. ^ It can provide superior blocking functions. It can be overcome to overcome the limitations of the conventional harmful multimedia collection technology. The media DB can be updated additionally, even if it is stored in the harmful multimedia files that are not transmitted through the Internet. A user computer that provides a more efficient function of limiting the use of harmful multimedia files. According to the present invention, it is constructed and operated according to each user's computer: a blacklist and an email address list. Because the installation is more harmful: the file file usage restriction system' can minimize the user's computer knowledge month b attenuation phenomenon. In addition, because a user's computer recognizes a harmful multimedia file has been added It is impossible to use harmful multimedia broadcasts, even if the harmful multimedia (4) case is redistributed to another computer through the Internet or another physical component, so as to avoid the spread of harmful multimedia files. By inserting a predetermined identification code, the encrypted file can be actively controlled to be transmitted through the Internet communication line. With the foregoing results, the parents can permit their younger son and daughter to calm down with 127849.doc -18 · 200837601 Using the Internet, and teenagers (4) and girls can avoid the harm of using harmful multimedia content rashly, and have a sound and healthy concept. In addition, the traffic of harmful multimedia standards occupying a large number of networks can be reduced, so that one Nationally efficient and effective network infrastructure is more secure. Although the preferred embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions can be made without departing from the context. The scope and spirit of the invention described in the scope of the following patent application. Therefore, it should be understood that the above specific The scope of the present invention is not limited by the specific embodiments described, but is defined by the scope of the claims and the like.
