BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus such as a printer, a facsimile, a multi-function product (MFP), and the like. The present invention relates to an RFID generation and tracking system and method for attaching the determined RFID, tracking the movement of the document to which the RFID is attached, and alerting the user if security is breached.

RFID tags are commonly used to track and detect attached objects. RFID tags are also an effective tool for tracking the movement of documents. The prior art disclosed in US patent application 2004/0041707 implements a technique for tracking documents with RFID tags for security purposes. Here, the prior art proposes a method of tracking a document by detecting an RFID tag attached to the document and a method of processing information in a database server. The prior art system includes a device for attaching RFID to a sheet of document, a database for RFID associated with a value assigned to the document, and an RFID detector for interfacing with the database. As the document moves, the RFID detector detects the information encoded in the RFID and sends it to the database server. The server uses the information to track the document.

1 and 2 illustrate a conceptual diagram for explaining a conventional RFID generation and tracking system. 1 and 2, a sensor is provided in an area of a suitable structure in which one or more documents can be located, and each sensor can output a response signal generated by sensing a document. The detection module is connected to receive a signal output from a sensor that generates a detection signal indicative of the movement of the document. The first set of sensors generates an output signal corresponding to the first position in the document, the second set of sensors generates an output signal corresponding to the second position in the document, and the next set of sensors performs the same operation. .

The prior art is very effective in tracking documents, but has some problems and drawbacks. Since the prior art generates RFID which has no relation to the content of the document, it is difficult to classify the document, and it is difficult to provide the document in response to the security of the document according to a group or position performing a common task.

In addition, the prior art attaches RFID to a predetermined specific location. If you know the specific location to which the RFID is attached, you can avoid printing any data at that particular location by simply removing the blank of the document containing the RFID and keeping it complete. Due to such manipulation, there is a problem that a security breach cannot be warned in real time.

The technical problem to be achieved by the present invention is to analyze the contents of the document to be printed, and to attach the RFID to determine the location and security level to attach, to track the movement of the document attached to the RFID and to warn the user when security is breached RFID To provide a generation and tracking system and method.

The RFID generation and tracking system according to the present invention for achieving the above object, the host device having an application for generating a document to be printed, by analyzing the document generated by the host device to determine the position on the document to attach the RFID A printer, an RFID attachment unit which generates the RFID and attaches it to the determined position on the document, and an RFID detection unit that tracks movement of the RFID-attached document and warns a user in real time if security of the document is breached. It is characterized by.

Preferably, the printer analyzes the contents of the document to determine the security level of the document, and the RFID attachment unit sets the determined security level to the RFID and attaches it to the determined position on the document.

Preferably, the printer randomly determines a position on the document to which the RFID is to be attached.

According to an aspect of the present invention, there is provided a method for generating and tracking an RFID device, including: analyzing a document to be printed and determining a location on a document to which the RFID is to be attached; generating and attaching the RFID to the determined location on the document; Printing the attached document, tracking the movement of the printed document, and alerting the user in real time if the security of the document is breached.

The determining may include analyzing the contents of the document to determine a security level of the document, and the attaching may include setting the determined security level to the RFID and attaching the determined security level to the location on the determined document.

Hereinafter, a method and system for generating and tracking RFID according to the present invention will be described in detail with reference to the accompanying drawings.

3 and 4 illustrate one embodiment of an RFID generation and tracking system according to the present invention, wherein the RFID generation and tracking system comprises a host device 300 and a printer 400. In addition, although not shown in Figures 3 and 4, it further includes an RFID detection unit (not shown) for recognizing a security / valid location tag or a legalized form and a security warning. The host device 300 includes a printer driver 350. The printer 400 includes an RFID attachment unit 420 and a print engine unit 450.

The host device 300 includes an application for generating a document to be printed. The host device 300 is preferably a printer, a multifunction printer or a computer.

The application provided in the host device 300 may be a text search application, an OCR application, an application in which a text search application and an OCR application are combined.

The printer driver 350 analyzes the document generated by the host device 300 to determine a setting environment to which the RFID is to be attached.

Here, the printer driver 350 analyzes the content of the document generated by the host device 300 to determine the security level of the RFID to be attached. The printer driver 350 analyzes the document to determine the type of document to be printed. If it is determined that the document is composed of text, the printer driver 350 searches for a security tag on the document. If it is determined that the document is not composed based on text, it is allowed to detect the security level of the document by watermark detection or OCR, and to set the security level high by the user's selection. If the administrator has already set a valid location ID for that security level, the same thing is assigned to that part of the document. The other part of the RFID is assigned a rather unusual number for the document. RFID and some document details communicate with a central server. Based on the administrator's settings, the document or part of the document is sent to a central server.

In addition, the printer driver 350 determines the document position of the RFID tag to be attached. The tag is determined in such a way that it is not printed in the empty space of the document. When printing a document composed of a plurality of pages, the printer driver 350 randomly changes the position of the ID in order to maximize the possibility of attaching the RFID to the crucial part of the document. When a long tag is used, the printer driver 350 attaches the tag to a line of text perpendicular to the line of text.

The printer 400 receives RFID information from the host device 300 and transmits the location and security level of the RFID to the RFID attachment unit 420. As shown in FIG. 3, the RFID attachment unit 420 may be provided at the front end of the print engine unit 450 to be connected to the printer driver 350. As shown in FIG. It may be provided in the.

If the RFID attachment portion 420 is provided at the front end of the print engine 450 as shown in FIG. 3, the print medium is not released until information is transmitted from the printer engine portion 450.

The RFID attachment unit 420 receives information about the security level of the RFID determined by the printer driver 305 and a position to be attached on the document.

When the ID is generated after the system is authenticated, the security level of the document can be selected by an appropriate means such as an OCR or a watermark detector. If necessary, you can log the incident on the security server. The user is also allowed to select from fields in other locations relative to other locations in the valid document. For example, research documents are valid in R & D departments and conference rooms, but not in shipping departments. These field entries are auxiliary to automatically generated security fields. The same one randomly instructs the RFID attachment 420 that the removal of the same can result in the amount of data loss since the system includes a printer having a sensor that senses the final position of the data being printed.

The RFID detection unit (not shown) tracks the movement of the document to which the RFID is attached by the sensor, and warns the user when the security of the document is breached. The sensor has a programmable memory used to store the group ID. This allows the sensor to operate even in a disconnected state in which the central data server cannot be connected. The RFID generated at the time of outputting the document is attached to a specific position of the document. If a particular part of the RFID attached to the document does not match the valid ID on the sensor, the sensor warns without having to connect to the central data server. Here, the user may be alerted by a device capable of transmitting a text message in real time by a bell or a wireless device that can be activated at a long distance. In general, the sensor transmits the RFID to the server using the ID and the position of the sensor and performs a corresponding operation.

5 is a flowchart illustrating an embodiment of a method for generating and detecting RFID according to the present invention.

First, it is monitored whether there is a print request from the application (operation 500).

If there is a print request in operation 500, the file type of the document requested for printing is analyzed (operation 510).

As a result of the analysis in step 510, it is determined whether the document is composed of text only (step 520).

If it is determined in step 520 that the document is not composed of text only, it is determined whether the document is composed of only images as a result of analysis in step 510 (step 530).

If it is determined in step 520 that the document consists only of text, the RFID number is determined based on the document tag and the security level (step 540).

If it is determined in step 530 that the document consists only of images, the RFID number is determined based on the document tag and security level using OCR or watermark detection (step 550).

If it is determined in step 530 that the document is not composed of only images, the RFID number is determined in consideration of all environments of steps 540 and 550 (step 560).

The RFID number determined in any one of steps 540 to 560 is transmitted to the driver (step 570).

After operation 570, a position on the document to which the RFID is attached is determined (operation 580).

The RFID is attached to the document position determined in operation 580 and printed (operation 590). The printed information of the document is now available.

According to the present invention, the RFID tag attached to the document operates on the basis of the idea of the security tag outputted. The printing system creates an RFID with security tags that has all the common tracking fields such as user ID, starting IP, and so on. The simplest detector with minimal memory can store a security ID and warn you if a security breach is detected. Minimal information processing capability is provided to detect a valid location field corresponding to each document to be detected. Sensors can detect security breaches without having to connect to the server, and IDs are provided as a basis for determining security breaches. If security is breached, other users can be alerted by other active devices that can send real-time alerts, such as devices that can be activated remotely and can send short messages over the air.

A simple measuring device is provided to collect infringement information. The sensor may have a better network capability to inform infringement alerts and may use RF signals to activate remote alerts.

The RFID deployment may consist of a unit separate from the printer. However, this arrangement has a problem that can cause security problems. Content analysis may be provided in the scope of the invention to end at the host device or to provide a breach measurement server.

Such a method and system of the present invention has been described with reference to the embodiments shown in the drawings for clarity, but this is merely exemplary, and various modifications and equivalent other embodiments are possible to those skilled in the art.
