Description

Printing method and apparatus using network printer

The present invention relates to a network printer, and more particularly, to a printing method and apparatus for printing a document using a network printer.

Most network printers on the market today can be accessed by anyone using a network printer shared through the Network Internet Protocol (IP) to print documents. Therefore, the reality is that the company or the government office is defenseless against the leakage of information assets, such as printing and leaking documents through a network printer.

The conventional printing method using a network printer firstly assigns and connects an IP to the network printer. At this time, after installing the printer driver, the client sets the printer driver's port to the IP assigned to the network printer, and executes a document output command to match the setting value to the network printer. Is printed. As described above, according to the conventional printing method using a network printer, as described above, any client personal computer (PC) capable of accessing the print server may be installed in a network environment in which a printer driver is installed and accessible to the corresponding port. You can print the document.

As a result, the conventional printing method using a network printer has a problem in that important security documents can not be prevented from leaking out since the document can be printed by all client PCs that can access the assigned IP. In addition, since information on which document is leaked at what time by which user is not known, there is also a problem in that it is not possible to appropriately take a follow-up action in which the document is leaked.

A print management unit for validating, storing the document information assigned with the secure output number and the document itself provided from the logged in user, and issuing the secure output number to the user and the secure output input from the print management unit If the number to be stored is matched with the registered user information input from the print management unit, and the document to be printed is determined to be an urgent document requiring urgent printing by using the result of analyzing various information included in the header, the document. Print and store And a network printer that provides the stored document to the user when the user provides the user information and authorization information that matches the secure output number, and the header including the various information includes the secure output number. It is preferred to be input from the user to provide.

Hereinafter, a printing method using a network printer according to the present invention and embodiments thereof will be described with reference to the accompanying drawings.

1 is a flowchart illustrating a printing method using a network printer according to an embodiment of the present invention and an embodiment thereof, including: registering user information, setting a security level, and storing user information in a network printer (10th to 10th). Step 14), checking the validity of the user, storing the document itself and the document information, issuing a secure output number, storing the secure output number (steps 16 to 24), and printing the document (steps 26 to 26). Thirtieth steps).

In the printing method using a network according to the present invention, in order to print a document provided from a user, first, user information provided from the user is registered in the user list, the security level of the user is set, and the user information registered in the user list is network printer. (Not shown) (steps 10 to 14).

For example, the user information is provided from the user through a personal computer (PC) (not shown) of the user (step 10). Here, the user information may include, for example, at least one of a user's name (ID: IDentifier), a password, a security level, a model of the user's PC, and an Internet protocol (IP) of the user's PC. The more items you include, the higher the level of security you can implement.

After the tenth step, the user information provided from the user's PC is registered in the database which is the user list, and the security level of the user is set (step 12). According to the present invention, the security level of a user may differently represent the number of documents that can be printed per day and / or the number of pages of a document that can be printed at one time through a network printer. For example, the user may limit the number of output of the daily document to 10 or limit the number of pages of the document to be printed to print within a maximum of 50 pages in one printing according to the user's grade.

After the twelfth step, user information registered in the user list is stored in the network printer (step 14). That is, the network printer stores user information registered in the user list.

On the other hand, after step 14, validating the user from the document information provided from the logged-in (log-in), and stores the document information assigned the security output number and the document itself provided from the logged-in user, The security output number is issued to the user, and the issued security output number is matched with the user information and stored in the network printer (steps 16 to 24).

For example, after step 14, document information and the document itself are provided from the logged in user (step 16). Here, the document information includes, for example, at least one of a security level, a document size, and the number of pages of a document to be printed.

After the sixteenth step, validity of the user is checked from the document information provided by the user, and a security output number is assigned to the document information (step 18). Here, checking the validity of the user means checking whether the document itself provided from the user can be printed through the grade of the logged-in user. In addition, a secure output number is assigned differently for each document to be printed. That is, the security output number assigned to each document is different.

After the eighteenth step, the document information assigned the secured output number, that is, the document information having the secured output number and the document itself provided from the logged-in user are stored (step 20).

After the twentieth step, a security output number assigned to the document information is issued to the user (step 22). After step 22, the issued security output number is matched with the user information and stored in the network printer (step 24). According to the present invention, secure output numbers provided to users and network printers can be encrypted.

On the other hand, as a result of analyzing various information included in the header belonging to the document given by the user providing the security output number issued in step 22, the user information stored in step 14 and the security output number stored in step 24 The document is printed (steps 26 to 30).

For example, it is determined whether the user provides the same number as the security output number issued to step 22 (step 26). If it is determined that the user does not provide the same number as the issued security output number, the user providing the current number is an unauthorized user, and thus the printing method shown in FIG. 1 ends. Therefore, a user who has not been issued a secure output number cannot provide the same number as the issued secure output number and cannot print a document.

However, if it is determined that the user provides the same number as the security output number issued in step 22, the document including the various information in the header is transmitted to the network printer (step 28). That is, since the user providing the same number as the security output number issued in step 22 is an authorized user, the network printer receives a document from the authorized user. Here, the various information means options such as user information such as user ID and IP of user PC, document information such as security output number, and whether the document to be printed is a general document, a security document, or an emergency document. May have information Hereinafter, a general document means a document that does not require security, a security document means a document that requires security, and an emergency document means a document that requires urgent printing while requiring security.

After step 28, as a result of analyzing the various information, the document is printed by the network printer using the user information stored in step 14 and the security output number stored in step 24 (step 30).

FIG. 2 is a flowchart for explaining a preferred embodiment 30A according to the present invention with respect to the thirtieth step shown in FIG. 1, in which a document is printed according to the type of document determined through analysis of various information. It consists of the steps (50 th-70 th steps).

First, after step 28, various types of information included in the header are analyzed (step 50). That is, user information, document information, and option information are analyzed.

After operation 50, it is determined whether the document to be printed is a security document or a general document by using the result of analyzing the various information (step 52). For this purpose, the result of analyzing the option information is used.

If it is determined that the document to be printed is a general document based on the analysis of the option information from the various information, the document is printed and provided to the user (step 60). As such, since the general document does not require security, the document is directly output without authenticating whether the user is an authorized user or an unauthorized user. According to the present invention, the step 30A shown in FIG. 2 may further include a step of notifying the user that the printing of the document is finished through the network printer after the 60th step.

However, if it is determined that the document to be printed is a secure document, it is determined whether the secure document is an urgent document requiring urgent printing (step 54). If it is determined that the document to be printed is not an emergency document, the user may be informed by a message that the document is to be printed by providing authorization information to the network printer (step 56). In operation 56A, a backup copy of the printed document may be stored. Therefore, when the authorized user in step 58 incorrectly provides the authorization information, for example, the security output number, in step 16, the network printer does not need to receive the document from the user again.

After step 56, it is determined whether the user provides the user information stored in the tenth step and the authorization information corresponding to the security output number stored in the twenty-second step (step 58). For this purpose, after the 56th step, the network printer waits for the printing of the document until the user provides the user information stored in the 10th step and the authorization information corresponding to the secured output number stored in the 22nd step. At this time, the document to be printed provided from the user is stored in the network printer. Here, the 56th step may be selectively provided. For example, if step 56 is not provided, step 58 is performed if it is determined that the document to be printed is not an urgent document.

If it is determined that the user provides the user information stored in the tenth step and the authorization information corresponding to the secured output number stored in the twenty-second step, the network printer prints the document and provides it to the user (step 60). However, if it is determined that the user provides mismatched authorization information, the administrator is notified that the user is an unauthorized user (step 62). Thus, an unauthorized user cannot print a document. As described above, when the document is a secure document, the document is printed through a user authentication operation that checks whether matching authorization information is provided from the user.

However, if it is determined that the document to be printed is an emergency document, the document is stored in a predetermined place instead of being printed and provided to the user (step 64). After the 64th step, since the document is printed and stored once, the user is informed by a message to take the stored printed matter by providing authorization information to the network printer (step 66).

After step 66, it is determined whether the user provides the user information stored in the tenth step and the authorization information corresponding to the security output number stored in the twenty-fourth step (step 68). According to the present invention, the sixty-sixth step shown in FIG. 2 may optionally be provided. For example, if step 66 is not provided, step 68 is performed after step 64.

If it is determined that the user provides the user information stored in the tenth step and the authorization information corresponding to the security output number stored in the twenty-fourth step, the stored document is provided to the user (step 70). As such, printing a document that requires security must wait until the user provides a matching authorization number, but a document that requires security but wants to be urgently printed is pre-printed before the user provides a matching authorization number. In addition, the printed emergency document may be provided to the user only when a corresponding authorization number is provided from the user.

However, if it is determined in step 68 that the user provides mismatched authorization information, the user is notified that the user is an unauthorized user (step 62). Thus, an unauthorized user cannot obtain a printout of the stored document.

On the other hand, a non-authorized user may use a security output number issued by an authorized user ID, for example, to transmit a document from a non-authorized user's own PC to a network printer instead of the authorized user's PC. In the case of transmission, in order to prevent an unauthorized user from printing a document, the thirtieth step shown in FIG. 1 is determined to provide matching authorization information in step 58 or 68. The method may further include determining whether the Internet protocol of the user providing the same as the Internet protocol of the authorized user. If it is determined that the Internet protocol of the user providing the matching authorization information is the same as the Internet protocol of the authorized user, the process proceeds to step 60 or 70. However, if it is determined that the Internet protocol of the user providing the matching authorization information is not the same as the Internet protocol of the authorized user, the flow proceeds to step 62. This is because if the Internet protocol of the user providing the matching authorization information is not the same as the Internet protocol of the authorized user, the user providing the matching authorization information is an unauthorized user. For example, since the Internet protocol assigned to an authorized user's PC and the internet protocol assigned to an unauthorized user's own PC are different, even if a matching authorization information, for example, an authorized user's secure output number is provided, the Internet The protocol prevents unauthorized users from printing the document.

On the other hand, while the unauthorized user uses the authorization information of the authorized user, for example, the security output number issued by the authorized user's ID, the document to be printed is not from the unauthorized user's own PC but the authorized user's PC. When sending to a network printer, the document can be printed via the network printer. Therefore, the thirtieth step shown in FIG. 1 is provided as follows so that an unauthorized user who prints a document can be confirmed later.

FIG. 3 is a flowchart illustrating an embodiment of the present invention with respect to the thirtieth step shown in FIG. 1, and photographing and storing a user who accesses or touches a network printer (80-84). Steps).

First, it is determined whether the user approaches or touches the network printer (step 80). If it is determined that the user approaches or touches the network printer, the photographed user who approaches or touches is photographed (step 82). After operation 82, the photographed result is stored (operation 84). At this time, the stored photographed results, such as moving image data, are transmitted to the administrator who manages the printing of the network printer. This is because it recognizes the user who printed the document without authorization and later uses it as legal evidence.

Meanwhile, according to the present invention, step 30A illustrated in FIG. 2 may further include storing output information related to printing of the document after step 60 or 64. Here, the output information may be log information on which user printed what document and when.

In addition, the step 30A shown in FIG. 2 may further include storing additional output information indicating whether the document output end signal and the document are normally printed after the 60th, 64th or 70th steps. . Here, the document output end signal indicates the time when the document was printed.

As a result, the administrator can more faithfully manage the printing of the network printer through information on the use of the network printer, that is, user information, document information, and output information.

4 is a flowchart for explaining another embodiment of a printing method using a network printer according to the present invention, and the method of printing a document using a result of analyzing user information and various information given from a user (100th to 100th). 104 steps).

According to another embodiment of the present invention, in order to print a document provided by the user using a network printer, first, user information provided from the user is stored in the network printer (step 100).

After step 100, a document is printed (steps 102 and 104) using the result of analyzing the various information included in the header given by the user and the stored user information.

For example, after step 100, a document including various information in a header given from a user is transmitted to the network printer (step 102). After step 102, the network printer prints a document using the result of analyzing the various information and the stored user information (step 104). Here, step 104 may be performed as shown in FIG. 2, and a detailed description thereof will be omitted. However, in step 58 or 66 illustrated in FIG. 2, it is determined whether the user provides authorization information that matches the stored user information.

That is, the printing method shown in FIG. 4 does not require a secure output number unlike the printing method shown in FIG. 1, and the user authentication job can be performed more simply than the printing method shown in FIG. 1.

According to the present invention, the document printed in the thirtieth step shown in FIG. 1 or the fifteenth step shown in FIG. 4 may be displayed as a security document. For example, a watermark of "security" may be displayed on the header or footer of the printed document.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of a printing apparatus using a network printer according to the present invention for performing the printing method using the network printer will be described as follows.

FIG. 5 is a block diagram of a printing apparatus using a network printer according to the present invention for performing the printing method according to the present invention shown in FIG. 1, to the user PC 120, the print management unit 122, and the network printer 124. It is composed.

The user PC 120 illustrated in FIG. 5 performs the 26th and 28th steps illustrated in FIG. 1. That is, the user requests a security output number for the document to be printed currently, and determines whether the security output number input from the user is the same as the security output number issued in step 22 (step 26). If the same number as the issued security output number is input from the user PC 120, a document including a header having various kinds of information is output to the network printer 124 (step 28).

The print manager 122 performs the tenth through twenty-fourth steps illustrated in FIG. 1. That is, the print manager 122 inputs user information from the user PC 120 (step 10), registers it in the database (step 12), and outputs and stores the registered user information to the network printer 124. (Step 14), the document information and the document itself are provided from the user logged in by the user PC 120 (step 16), the user is validated from the provided document information, and the security output number is assigned to the document information. Assigning (step 18), storing the assigned document information and the document itself provided from the logged in user PC 120 (step 20), and outputting the security output number to the user PC 120 (22) In step 24, the security output number is outputted to the network printer 124 and stored (step 24).

The network printer 124 serves to perform the thirtieth step shown in FIG. That is, the network printer 124 matches and stores the security output number input from the print management unit 122 with the registered user information, and stores the document input from the user PC 120 in the header input from the user PC 120. As a result of analyzing the various pieces of information included, the information is printed according to the matched and stored user information and the security output number (step 30). Here, the header including various information input to the network printer 124 is input through the user PC 120 from an authorized user who has provided the same number as the security output number issued in the twenty-second step.

At this time, unlike the above, step 26 may be performed in the network printer 124 instead of the user PC (120). In this case, the network printer 124 determines whether the same number as the issued security output number is input from the user PC 120 (step 26). If it is determined that the same number as the issued security output number is input from the user PC 120, a document having a header including various information is input from the user PC 120.

According to the present invention, the print manager 122 shown in FIG. 5 sets the security level of the user and outputs the set security level to the network printer 124. At this time, the network printer 124 prints the document in response to the set security level input from the print manager 122. That is, the network printer 124 limits the number of documents to be printed and the number of pages to be printed for each user according to the security level input from the print manager 122.

FIG. 6 is a block diagram of a preferred embodiment 124A according to the present invention of the network printer 124 shown in FIG. 5, wherein the first and second storage units 140 and 142, the information analyzing unit 144, Comparing unit 146, printing unit 148, storage unit 150 and the notification unit 152.

The network printer 124A shown in FIG. 6 serves to perform step 30A shown in FIG. For example, the first storage unit 140 inputs the security output number and the user information from the print manager 122 through the input terminal IN1, and stores the input security output number by matching the user information. At this time, the second storage unit 142 stores the document itself input from the user PC 120 through the input terminal IN2.

The information analyzing unit 144 performing the 50 th, 52 th and 54 th steps analyzes various information input from the user PC 120 through the input terminal IN3 and determines, for example, the type of the document and the analyzed result. Are output as the first control signals to the printing unit 148, the storage unit 150, and the notification unit 152, respectively.

In order to perform the 58th and 68th steps, the comparison unit 146 may include the authorization information input from the user PC 120 through the input terminal IN4, the user information read from the first storage unit 140, and the security output number. The comparison result is output as the second control signal to the printing unit 148, the interpolation unit 150, and the notification unit 152, respectively.

The printing unit 148 stores the second storage in response to the first control signal input from the information analyzer 144 and the second control signal input from the comparing unit 146 to perform the 60th or 64th step. The document read from the unit 142 is printed, and the printed result is output through the output terminal OUT2 or output to the storage unit 150. For example, if it is recognized that the document is a general document through the first control signal, the printing unit 148 performing the sixty-sixth step prints the document read from the second storage unit 142 and outputs the printed result to the output terminal. Output via OUT2. Alternatively, the printing unit 148 performing the sixty-stage operation may store the second storage if the document is recognized as a non-urgent security document through the first control signal and the user provides the corresponding authorization information through the second control signal. The document read out from the unit 142 is printed, and the printed result is output through the output terminal OUT2. In addition, if it is recognized that the document is an urgent document through the first control signal, the printing unit 148 performing the 64th step prints the document read from the second storage unit 142 and outputs the printed result. Instead of outputting through OUT2, it outputs to the storage unit 150.

The storage unit 150 stores the print result output from the printing unit 148 in response to the first control signal and stores the print result in response to the second control signal to perform the seventy-stage step shown in FIG. 2. Outputs the result to the user through the output terminal OUT3. For example, if it is determined that the document is an urgent document through the first control signal, the storage unit 150 receives and stores the printed result output from the printing unit 148 and matches the authorization information through the second control signal. If is recognized as being provided, it prints the stored printed result through the output terminal OUT3. Therefore, when it is recognized that the user provides the mismatched authorization information through the second control signal, the storage unit 150 does not output the stored printed result through the output terminal OUT3, so that an unauthorized user is stored. Do not take documents.

The notification unit 152 performs the 56th, 62th and 66th steps shown in FIG. 2. For example, the notification unit 152 may notify the user through the output terminal OUT4 in response to the first and second control signals through the output terminal OUT4 (step 56 or 66), or the unauthorized user may read the document. Notify that the user wants to print out through the output terminal OUT4 (step 62).

FIG. 7 is a block diagram of a printing apparatus using a network printer according to the present invention for performing the method shown in FIG. 3, and includes a sensing unit 160, a photographing unit 162, and a third storage unit 164.

The sensing unit 160 performing the 80th step detects a user approaching the network printer 124 or touching the network printer 124 and outputs the detected result to the photographing unit 162. At this time, the photographing unit 162 photographs the user in response to the detected result input from the sensing unit 160 and outputs the photographed result to the third storage unit 164. That is, when it is recognized that the user approaches the network printer 124 or touches the network printer 124 through the detected result, the photographing unit 162 photographs the user.

At this time, the third storage unit 164 stores the photographed result input from the photographing unit 162, and outputs the stored result to the manager through the output terminal OUT5. Therefore, the administrator may recognize the unauthorized user of the network printer 124 by using the captured moving image data stored in the third storage unit 164.

The aforementioned sensing unit 160, the photographing unit 162, and the third storage unit 164 illustrated in FIG. 7 may be provided inside the network printer 124 illustrated in FIG. 5, or the network printer 124. It may be arranged in the vicinity of.

As described above, the printing method and apparatus using the network printer according to the present invention allows only authorized users to print documents through the network printer, thereby preventing leakage of security information in the form of documents by unauthorized users. Unlike a storage medium such as a disk, it is possible to compensate for the very weak part of the security that leaks information by printing a document, allowing an unauthorized user to take a quick action by real time recognizing the use of a network printer. Even if the printing of a document by an unauthorized user is successful, the security of the document can be maximized when printing the document through a network printer, such as recording a video of the unauthorized user and providing important evidence in a post-legal dispute. Has the effect.
