Description

How to secure received data

The present invention relates to a method of securing a received data of a facsimile. More particularly, the data received in the absence of the user is stored in the memory without printing, and the user can print the data stored in the memory only when a password is input. It relates to a receiving data security method.

In general, a facsimile is a device capable of performing a simulated transmission since the fax data read from the document is transmitted to an external facsimile via a communication line or a fax data received from an external facsimile is printed out through a communication line.

In recent years, as fax communication becomes general, much information is exchanged through facsimile. Especially for documents that need to be processed quickly, the exchange of information through facsimile is very effective, thereby greatly improving work efficiency.

However, when receiving data through such a facsimile, since the received data is printed and output even when the user is absent, if the received document is an important document that requires confidentiality, it is not exposed to others and is not confidential. A problem occurs.

Accordingly, an object of the present invention is to solve such a problem, and an object of the present invention is to set an absent time so as to prevent exposure of a document received when the user is absent to another person. The present invention provides a method for securing received data of a facsimile that can set a password for storing the data stored in the memory and outputting data stored in the memory.

According to an aspect of the present invention, when data is received from the outside in the facsimile, the present invention compares a current time at which the data is received with a preset absent time in the security mode of the facsimile, If included, storing the received data in the memory of the facsimile, if the print key is selected to output the data stored in the memory, requesting input of a preset password in the security mode of the facsimile, the input password and the And if the set password matches, printing the data stored in the memory.

Preferably, the security mode of the facsimile determines whether a predetermined key is selected from among a plurality of keys of the facsimile is selected, and if the predetermined key is selected, the absent time for storing the data received in the facsimile in the memory; And setting a password for outputting data stored in the memory when the absent time is set.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of a facsimile applied to the present invention, FIG. 2 is a flow chart for setting a security mode in the facsimile, Figure 3 shows a method for securing received data of the facsimile of the present invention An operation flowchart for performing the operation is shown, and FIG. 4 illustrates an input screen appearing on the display window according to the security mode setting of FIG. 2.

As shown in FIG. 1, the CPU 1 generally controls various operations of the facsimile according to a set program. In particular, the CPU 1 compares the time of receiving data from the outside with the absent time, and receives the data according to the result. To control.

The memory 2 stores program data, protocol data, text data, work contents related to transmission and reception, and accesses or stores data under the control of the central processing unit 1, and in particular, Absence time and password are stored.

The operation panel (OPE) 3 includes a plurality of keys capable of generating key data of the facsimile, in particular, a key for setting the absence time, and when the key data is generated, it is input to the central processing unit 1 and the central processing is performed. And a display window 3a capable of displaying the display data of the device 1.

The scanner 4 scans an image of an original, converts the image into digital image data, and transmits the image data to the central processing unit 1.

Under the control of the central processing unit 1, the modem 5 modulates and outputs the output data of the central processing unit 1 in analog form, and demodulates and outputs the analog input signal.

The NCU (Network Control Unit) 6 operates under the control of the central processing unit 1 to form a call loop of a general telephone network (consisting of rings and tips) and to provide signals from the modem 5 and the telephone network. Interfacing.

The printer 7 prints the received data according to the control signal from the central processing unit 1, and the sensor unit 8 detects the remaining amount of the recording paper or the document and detects it on the central processing unit 1. The speaker 9 generates an alarm by the control signal output from the central processing unit 1.

The operation of the present invention configured as described above will be described in detail with reference to the accompanying drawings.

First, a method of setting an absence time and a password in a facsimile will be described with reference to FIG. 2.

The central processing unit 1 of the facsimile checks whether a preset key for setting the absent time is selected from among the plurality of keys of the operation panel 3 (S201). The message is displayed on the display window 3a of the operation panel 3 (S202) (see FIG. 4A). Here, the user inputs the absent start time and end time by using a plurality of keys of the operation panel 3.

The CPU 1 checks whether the user inputs the absent time (S203), and stores the absent time set by the user in the memory 2 (S204).

When the absence time setting is completed, the central processing unit 1 displays a message requesting a password input on the display window 3a (S205) (see FIG. 4B), and checks whether the user inputs a password (S206).

If there is a password input from the user, the password is stored in the memory 2 (S207), and the process of setting the security mode in the fax is terminated.

In this way, the central processing unit 1 of the fax in which the security mode is set checks whether data is received from the outside (S301), and if the data is received, retrieves the current time (S302).

The CPU 1 determines whether the searched current time is included in the preset absent time (S303), and if the current time is included in the absent time, the CPU 1 stores the received data in the memory 2 without outputting it (S304). ).

The central processing unit 1 checks whether the received data has been stored in the memory 2 (S305), and when the storage is completed, checks whether a print key is selected from a plurality of keys of the operation panel 3 (S306). Here, when the print key is selected, the CPU 1 displays a pre-stored message requesting a password input on the display window 3a (S307), and compares whether the password input by the user is the same as the preset password (S308). ).

If the comparison result is the same password, the CPU 1 prints the received data stored in the memory 2 through the printer 7 (S309), checks whether the printing is completed (S310), and prints when the printing is completed. After the operation ends (S311), all processes are terminated.

On the other hand, if the time at which data is received is not included in the absence time in step 303 (S303) comparing the current time and the preset absent time, a general operation of printing the received data to the printer 7 is performed (S312). .

In addition, if the password is not the same in step 307 (S307) in which the password entered by the user is compared with the preset password, a message indicating the occurrence of an error is displayed on the display window 3a (S313), and the process ends.

As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims below and equivalents thereof.

As described above, according to the reception data security method of the facsimile according to the present invention, the user sets the absence time and the password in the facsimile as necessary, the data received during the set absence time is stored in the memory without output, In order to output the data stored in the user, a password must be entered, which is an advantage of preventing important documents from being exposed to others.
