Description

Cloud printing system using mobile phone and short message service server {Cloud Printing System using Short Message Service Server and Mobile phone}

The present invention relates to a printing system using a mobile phone and an SMS server. Specifically, when a notebook, a smartphone, a tablet PC user, and a general PC user send a spool file to a common MFP, the mobile phone number is sent to the spool server together with the spool file. The spool server sends a short message including an authentication code to the mobile phone of the corresponding number, and the user sends a short message including an output location code indicating the authentication code and the location information of the multifunction device to the received calling number. The present invention relates to a printing system in which a server authenticates itself using a short message, performs output to an output included in the short message information, and performs a payment function to use an output device at an arbitrary position.

In order to perform printing in a conventional university or public library, a user had to use a designated printer and a specific PC connected thereto. However, in recent years, many people work on documents with personal notebooks or tablet PCs, but in order to print files, they need to be transferred from a designated PC connected to the output device after transferring files to a storage device such as USB. There was a troublesome procedure. In addition, there is a problem that a separate procedure is required to pay for the output price even after requesting the output from a designated PC, and when there are many waiters in the printer requesting the output, it becomes a security problem because others can see the output.

In order to solve this problem, recently, a system that uploads a file to be output to a web hard, downloads from a PC connected to a desired output device, and requests that the output is performed is used. In such a system, even if someone else is printing or waiting in advance before waiting for the output to be printed on the writer, the output may be secured and the output file may be deleted from the user's PC. There is a problem that others can see the output by easily restoring the back on the PC.

Recently, the printing system using electronic money has been in the spotlight with the proliferation of transportation cards. However, the terminal must be equipped with RFID recognition for user authentication for printing. There are restrictions.

Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

1 shows a schematic diagram showing the components of the present invention. As shown, the printing system of the present invention includes a user PC, a spool server, an SMS server, an output device, and a user mobile phone. The network printing system of the present invention transmits the spool data sent by the user to the spool server to the writer mapped to the output location code designated by the user through SMS reply, so that the output is performed at the desired location at the same time as the user authentication. Specifically, in the present invention, after the user transmits the output to the spool server using a PC in a mobile environment, performs authentication by using a mobile phone and an SMS server, the SMS server transmits an output command from the mobile phone to the SMS server. It transmits the output data to the writer corresponding to the output location code input by the user from the spool server.

FIG. 2 is a schematic block diagram showing the components of the system and the relationship between the components according to an embodiment of the present invention. Hereinafter, the components of the present invention will be described with reference to FIGS. 1 and 2.

The user PC of the present invention is a notebook, a smartphone, a tablet PC, a user owned PC, etc. owned by the user, in addition to the designated public PC connected to the output device. The user PC transmits a file to be output to the spool server in a network environment such as a LAN or wi-fi. At this time, the output data file is transmitted to the spool server in the form of an SPL spool file generated through a virtual printer driver. The generated SPL spool file can be printed on any type of multifunction device or printer. Conventionally, in order to perform output using a common writer, an output file and an output request have to be sent directly to a writer or a spool server from a designated PC connected to the writer, but in the present invention, a user PC which has created an output target file without going through a public PC Because spool data is sent directly from the spool server, there is no inconvenience to move the output file to the public PC as before.

In addition, if the operating system (OS) of the user's PC does not support a virtual printer driver such as a smartphone, the original file may be uploaded to the spool server as it is, and the file transmitted from the spool server may be automatically converted into an SPL spool file format.

A client program is installed in the user PC of the present invention, which not only transmits the spool data described above, but also transmits the mobile phone number of the user together with the spool data to the spool server. You can see that the user who sent the spool data and the user requesting the output from the writer are the same person. In addition, the client program may determine the number of output information, the number of sheets, paper size, black and white / color classification, document name, document file type, output direction, and output page order. Is sent to the server.

As shown in Figure 2, the spool server constituting the system of the present invention is provided with a spool management module, a settlement management module, an authentication code management module, a call number management module and received from the user PC spool data and settlement data, authentication code data The spool server receives the user's mobile number, authentication code and writer location code information from the SMS server and transmits the spool data to the corresponding writer.

The spool management module analyzes the SHD file received from the user's PC, and inputs the user's mobile phone number, number of copies, paper size, black and white / color classification, document name, document file type, output direction, output page order, and settlement data. The output information is stored in the spool database, and the output data, which is the document content, is allocated to the spool area. Also, after a certain time (value set in the Management System) in the spool area of the spool server, the garbage spool data and the corresponding output history of the spool database are deleted. At this time, when the spool threshold area reaches the spool policy, the spool scheduler is automatically executed in the FIFO method.

As above, the spool server manages SPL and SHD files and output data. When the user requests output by specifying the location code of the writer through the SMS reply of the mobile phone, the spool server sends the corresponding spool files (SPL and SHD) to the user. Send to the requested writer.

In addition, the spool management module checks whether the mobile phone number of the user received through the SMS server is the same as the mobile phone number stored in the spool area, and performs user authentication first.

The spool server of the present invention is managed by a spool management system, which performs system management, service management, service operation management, service revenue management, and customer center management. The system management relates to setting login authority and menu authority of an administrator, and the service management includes spool policy, spool threshold area, service usage history inquiry, output history inquiry, driver information management, writer information management, writer location code management, Commodity management. In addition, the service operation management is related to the failure and monitoring of the service, the service sales management is related to querying the sales information by period, output room, customer center management is to allow the administrator to register the service content output from the user PC .

The calling number management module selects a calling number to send a text message to a user's mobile phone through an SMS server. The SMS server may be provided with a plurality of call numbers in one server, or may be provided with each call number in a plurality of SMS servers, the call number management module is one or more SMS connected to the network printing system of the present invention To store all caller ID number of the server, select the caller ID to send / receive the text message to prevent the call and transmission of the caller from the caller. The SMS server operating the caller number selected by the caller ID management module plays a role of relaying messages between the spool server and the user's mobile phone.

The authentication code management module checks whether the user who sends the output data to the spool server and the user who requests the output to a specific writer are the same. Specifically, as shown in Figure 2 generates a verification code and sends a short message containing the verification code to the mobile phone registered by the user through the SMS server. The authentication code management module not only generates an authentication code but also performs user authentication by checking whether the authentication code included in the short message received from the user's mobile phone and the sent authentication code are the same as described below. As such, sending the authentication code to the user's mobile phone and confirming whether a reply message including the same authentication code is received allows the dual authentication and security to be performed in parallel with the authentication through the mobile phone number described above.

The settlement management module is confirmed whether or not to settle in the payment system associated with the system of the present invention through the user's mobile phone as described below. Specifically, the settlement management module generates a separate verification code required for settlement and transmits it to the user's mobile phone through the SMS server, and then checks whether the payment is made through a reply or checks the settlement and settlement using the authentication code management module. You can also generate an authentication code to use.

The SMS server of the present invention includes a dispatch message management system and a reception message management system, and transmits a message for performing authentication and output commands between the spool server and the user's mobile phone by receiving information from a user's mobile phone, which will be described later, and transmitting the information to the spool server. It plays a role of relay of reception. At this time, when the user returns a short message received through the mobile phone and sends the authentication code together with the output location code to the SMS server, the SMS server transmits it to the spool server again, and the authentication code issued by the authentication code management module of the spool server Check whether and the received authentication code matches.

Specifically, the SMS server receives the mobile phone number information and issuance authentication code, etc. in the form of Text data from the spool server, and sends a short message to the mobile phone number, the user reply when the SMS short message is received in the mobile phone Through the function, input the output location code and the authentication code in the short message input window and press the send button to send it back to the SMS server. The SMS server retransmits this to the spool server in text form, and determines the sender and output requester of the spool data as the same person, and transmits the spool data to the output location code and the mapped writer to complete the output. That is, even without a separate device for identity verification, it is possible to check whether the output request by the user who sent the spool data through the user's mobile phone and SMS server.

The output unit is capable of communicating with the spool server, and receives the spool data from the spool server to perform the output. At this time, the output device may have a fixed IP on the network for communication with the spool server, and if the mapping on the DB with a numeric output location code to easily identify the fixed IP assigned to the wide area network throughout the country (Wide Area Network) Enables printing on the network .

In front of the output, a unique output location code is set so that the user can easily identify with the naked eye, and a unique identification number is attached like a vehicle number. When the user requests output through a mobile phone, the output location code is inputted. You can specify the writer to perform the output. In the related art, the spool data sender and the output requestor must perform the same person authentication at the same time as the output request from the corresponding output device. However, in the present invention, since the user authentication can be performed through a mobile phone, the user outputs to a remote output device without going directly to the output device. You can request

In the system of the present invention, the mobile phone is not only a means for authenticating that the person requesting the output of the spool data to the spool data sender and the specific writer is the same person, but also a means for inputting information on which output is to be performed. As described above, when transmitting the spool data from the user PC to the spool server, the user transmits the number of the specific mobile phone together, and sends a short message to the SMS server through the mobile phone to receive the identity verification. In this case, when the mobile phone sends a text message to the SMS server, the mobile phone number is automatically identified and transmitted to the spool server. In addition, the SMS server and the mobile phone may be to send and receive information on the spool data, the SMS server may transmit the title of the spool data received from the user PC to the mobile phone in the form of a short message, the user guides the short message In response to the input of the response information through the input unit, such as a key button, the touch pad to generate a message to reply. In this case, the response information may include checking the output position code, whether or not the spool data is normally registered, title information, and status information such as waiting for output.

3 is a detailed flowchart of the entire system according to an embodiment of the present invention. Referring to the drawings, referring to the system of the present invention, first, a cloud printing driver is set through a client program on a user PC. The cloud printing driver enables the output device of the system to be used instead of the output device connected locally through the user's PC. When the cloud printing driver is selected, the client program requests input of a mobile phone number of the user for authentication, and when a user inputs it and issues a print command, the client program inputs an output data file and a mobile phone number from the user PC to the spool server. The containing spool data is transferred. After sending the spool data to the spool server, the spool server sends the authentication code to the SMS server if it generates a mobile phone number, the title of the output data file, and the authentication code. The SMS server sends a short message to a mobile phone of a number previously input by a user through a dispatch message management system. The user receiving the short message will return the output location code of the output device to be output through the mobile phone. If the authentication code is sent as described above, the reply message includes the authentication code as well as the output location code. It should be possible. The SMS server extracts the authentication code and transmits it to the spool server if the received mobile phone number, output location code, and authentication code are included. The spool server performs user authentication by comparing the mobile phone number and the authentication code. If the user authentication is successful, the spool server transmits the spool data to the output mapped to the input output location code.

In addition to the text message regarding the authentication code and the output location code, the SMS server may additionally send a text message for checking the title of the output data file, checking information on payment and settlement, and verifying the authentication code necessary for this. Authentication and verification take place in the corresponding module of the spool server.

Hereinafter, an example of using the system from the user's point of view will be described. College student A wants to print out a report to be sent to the school immediately because of a breakdown in the home printing machine. First, Mr. A completes the document on his home PC, selects the cloud printing driver, presses the file print button, and the SPL type spool data is ready to be sent to the spool server in the local center. In this case, enter the output location code along with the verification code on the user's mobile phone. SMS short message is received. After checking the SMS message, Mr. A moved to the school to check the output location information displayed in front of the multifunction device in order to perform the output from the output device closest to the classroom, and then input the output location code as a reply message to the received SMS short message. After that, reply with the verification code to the received calling number. In this case, the reply function including the contents of the received message may be used, or the authentication code may be memorized and may be written in the reply message. The reply message and the output location code may be successively written or "/", ",", spaces, etc. You can separate the code by writing. The SMS server that returned the message from the user transmits the authentication code and the output location code among the contents included in the message to the spool server in real time, and the spool server performs the user authentication and then outputs the spool data mapped to the output location code. The output will be sent normally.

As another example, when college student A needs to send data to friend B of school, he checks the location code of the printer selected by B and requests output to the printer without using an e-mail. You can have Mr. B take the output.

In the present invention, the information checked and input between the SMS server and the mobile phone is not limited and may be subject to reconfirmation. For example, the short message generated by the SMS server may be arbitrarily selected from the name confirmation of the spool data, the number of output pages, black and white / color selection, the paper size, the location code confirmation of the output requesting device, and the output authentication code. In addition, when the spool server manages an SMS server having a different phone number through a call number management module having a plurality of SMS servers, the spool server may arbitrarily change the short message call number to increase security. In other words, if there is only one outgoing number of the SMS server, the user may memorize it and reply from another person's mobile phone or user's PC instead of his or her own mobile phone. In this case, a security problem may occur. It is desirable to operate multiple caller ID numbers in the SMS server so that the user can reply to the short message only from his mobile phone. In this way, when multiple SMS servers with different calling numbers are operated through the calling number management module of the spool server, the same user sends multiple files or prevents excessive message transmission and reception to one SMS server during the output concentration time. Minimize failures and distribute the load of message traffic, which has the side effect of efficient operation.

In addition, as another embodiment of the present invention, in addition to the user authentication through the mobile phone number itself, it is possible to perform a system using a separate authentication code. Specifically, when the spool data is transmitted from the user PC to the spool server, a combination of numbers may be displayed to the user as a code for authentication along with the transmission completion message. That is, when the short message is transmitted to the user's mobile phone, the authentication code is not included, but when the spool data is transmitted from the user's smartphone or the user's PC, the authentication code is displayed on the screen, and the user is sent an SMS. When receiving a text from the server, it may be configured to enter an authentication code when replying to it.

This system may proceed with the billing by using the information transmission between the settlement management system of the spool server described above, the SMS server, and the mobile phone. First, after registering a member for prepayment on the homepage opened by the service provider, the prepayment may be performed by charging the cyber money in connection with the electronic payment agency system (hereinafter referred to as "PG system"; Payment Gateway System). In this case, the information about the charged cyber money is stored in the member management server, and the member management server transmits and receives information to and from the SMS server and the spool server, and sends the balance information of the cyber money to the SMS server, and the spool server The billing data is received from the settlement data. Specifically, when the user sends a text message to the mobile phone via the SMS server, the SMS server sends a message confirming the cyber money and information about the cyber money that is necessary for outputting the text message, and the user Charging can be performed by checking whether payment is made through the keypad input of the mobile phone.

In addition, when transmitting the spool data to the spool server in connection with the PG system, after receiving the payment verification code to the mobile phone, enter the payment verification code when performing payment on the user PC, and when the payment is confirmed, the spool server outputs It is also possible to charge by transferring spool data. Of course, the charging means can be a variety of means, such as mobile phone micropayment, credit card payment, cyber money, it is also possible to earn credit payment method through the membership registration function.

On the other hand, the printing system using the SMS server of the present invention can further configure the ARS server to increase user convenience. Specifically, as shown in Figure 1, by additionally configuring the ARS server to communicate with the spool server, the user authentication including the mobile phone number in addition to the text message service in addition to the method of accessing the ARS server using the mobile phone of the corresponding number Can be. Specifically, a request for transmission of spool data and a mobile phone number from a user PC to a spool server, and when reception is completed in the spool server, a text message transmission for informing a calling number or an output request method to the mobile phone number to an SMS server. Request, and the SMS server may guide the output request method and the like using the mobile number as the received number. For example, the user can confirm the intention of the user by making a call to the ARS server or requesting a reply or replying to a text message once, and canceling the output request once. In addition, if the text message is not received from the user's mobile phone as described above, the user dials a fixed ARS number and accesses it. Then, the user is instructed to retransmit the spool data by grasping the processing status of the spool data or the like. You can request to resend text messages. In this case, it is preferable that the fixed ARS number is known through a notice around the client server or the output device of the user PC.

The system of the present invention requires communication between the user PC and the spool server, and can use a wired network or a short-range wireless network in a limited space such as a company, a school, or a library. However, when it is necessary to be applied to a large space such as a user's home and the subway, the user's home and school, of course, TCP / IP communication can be used.

As described above, in the printing system of the present invention, since the spool data transmitted from the user PC to the spool server is sent to the writer specified by the user through authentication of the mobile phone and the SMS server, the printing system can be prevented from being outputted without authentication. Can be.

In addition, by using the user's personally owned and equipped PC as well as the designated PC connected to the writer and the local or internal network, the output is sent to the spool server anytime and anywhere in the mobile environment. This allows remote printing between different users.

The printing system described in the present invention weaves the existing individualized output device into a network, so that the user can conveniently use remote printing to the Ubiquitous environment such as convenience stores, government offices, universities, and corporations in the country, so that the movement and manipulation of the user's output can be achieved. It can greatly reduce the inconvenience and increase the efficiency of using the existing output.
