More specifically, an image or a document such as a photograph is authenticated through an authentication system such as RFID (Radio Frequency Identification), such as a printer or a monitor. A file output system using RFID output through an output device and a control method thereof.

RFID (Radio Frequency Identification) is a contactless recognition system that transmits and processes information of objects and surrounding environment information using a small semiconductor chip. Unlike barcodes, it does not require direct contact or scanning, so it is evaluated as a technology to replace barcodes. RFID is a radio wave identification system that attaches small chips to various items and transmits and processes information of objects and surrounding environment information at radio frequency.

The RFID includes a reader having a reading and decoding function, an RFID tag incorporating unique information, operating software, and the like, and can be used in conjunction with a network as necessary. An RFID reader or reader processes information by wirelessly identifying an RFID tag attached to an object to read or store the information.

In addition, the control method of the printer system using the RFID (S400) may further comprise the step (not shown) of reading the first RFID tag information including the coupling tag information from the remote with the contents of the file.

The control method (S400) of the printer system using RFID according to the present embodiment relates to the control method of the printer system 100 using RFID illustrated in FIGS. 1 and 2.

In the file reading step S410, first RFID tag information including coupling tag information is recorded, and a file to be output is read. In the first RFID tag information reading step S420, first RFID tag information in a file to be output is read. In this case, the coupling tag information included in the first RFID tag information may be read together. The coupling tag information may be another RFID tag information that can replace the first RFID tag information.

The output steps S430, S440, and S500 include an encryption determination step S430, a security output step S500, and a general output step S440. In the determining whether to embed the cipher (S430), it is determined whether the cipher is embedded according to whether the file to be output includes the first RFID tag information and the coupling tag information.

The secure output step S500 is performed when a password is included in the file to be output and outputs the file through an authentication process as shown in FIG. 5. In the general output operation S440, the output is performed regardless of the first RFID tag information or the coupling tag information.

The file to be output may be at least one of a photo file, an image file, various video, audio, and document files. Preferably, the first RFID tag information is included in each file, and the first RFID tag information includes coupling information that can be used for authentication for output. As illustrated in FIG. 3A, the first RFID tag information 31 including the coupling information may be recorded in the file to be output.

The output in the output stages S430, S440, and S500 may be a printing operation through a printing apparatus such as a printer or screen printing through a display apparatus such as a display panel.

If so, the coupling information is read from the first RFID tag information (S520). In this case, when the coupling information is not included in the first RFID tag information, the content of the file may be output in the output step S570.

The authentication information reading step (S530, S540, S580) may include an authentication information input method selection step (S530), authentication information reading step (S540), and determining whether the coupling tag is recognized by the RFID reader (S580). have.

In the authentication information input method selection step (S530), it is selected whether to receive information required for authentication from an RFID tag or another device in which the second RFID tag information including the coupling tag information is recorded from the outside. The coupling tag information may be input by means other than an RFID tag, and the coupling tag information may be a USB memory in which authentication information is stored, another storage medium in which authentication information is stored, authentication information input by wire or wireless at a remote location, or an RFID reader. And it is a step of selecting so that the authentication information can be received from at least one of the keyboard through which the authentication information is input from the user, any one can be set as a default value, preferably the RFID reader can be selected.

In the authentication information reading step (S540), the authentication information is extracted from the signal including the authentication information or the authentication information which can be input from the method selected above, and the information is read. In addition, in the determining whether the coupling tag is recognized (S580), when the RFID reader is selected in the authentication information input method, a predetermined signal is transmitted to recognize the RFID tag that can be recognized. If at least one tag is recognized, the recognized tag information is transmitted to the authentication step (S560). In this case, the recognized tag may be a second RFID tag.

In the authentication step (S560) it is determined whether the authentication information received in the above manner corresponds to the coupling information of the first RFID tag information. In the present embodiment, the authentication step (S560) determines whether the authentication information matches the coupling information of the first RFID tag information.

In the output steps S570 and S590, when the authentication result authentication information in the authentication step S560 corresponds to the coupling information of the first RFID tag information, the contents of the file are output (S570). In this embodiment, when the coupling tag information of the second RFID tag information matches the coupling tag information of the first RFID tag information, the content of the file may be output.

If the authentication result authentication information of the authentication step (S560) does not correspond to the coupling information of the first RFID tag information, the warning message may be output without outputting the file content (S590).

When generating a file, an ID for the encrypted information can be inserted at the beginning or the middle of the stored information of the photo or document. A warning message may be sent when the coupling tag information is not detected or inputted within a predetermined time while reading the file.

In this case, if the file is a picture, the index screen or the blind process may be performed, and if the file is a document, the imaged index screen may be displayed on the screen. If there is no screen display device, the corresponding document or picture may be notified through the voice information.

When there is no coupling tag information, in the case of printing for photo printing, only the index of the photo may be displayed or output on a screen which is normally installed, and a copyright warning message may be output on the upper portion of the screen.

Therefore, the contents of the file secured by authenticating the contents of the file in which the information of the first RFID tag including the coupling tag information is recorded by the coupling tag information included in the second RFID tag different from the first RFID tag. You can output

That is, by authenticating with the coupling tag information included in the RFID tag, even if the RFID tag used at the time of file creation and the RFID tag used at the output of the file are different, secure output is possible if the coupling tag information is identical. Do.
