Description

Security method of transmission data in facsimile device

The present invention relates to data transmission of a facsimile apparatus, and in particular, in order to transmit and input a password for security of the transmission data, the received data also enters a password in the facsimile apparatus to be printed out only when both numbers match It relates to a security method of the transmission data.

In general, a facsimile apparatus reads an image recorded on the original surface by scanning light onto the original surface on which the information is recorded and converting light reflected from the original surface into an electrical signal. It is a communication terminal that transmits data to a receiving terminal through a telephone line or, conversely, reproduces an image identical to information recorded in an application based on image data transmitted from an opposite terminal.

1 is a block diagram showing an internal configuration of a facsimile apparatus equipped with the above-described functions. In the drawing, reference numeral 10 denotes a reading unit for reading an image recorded on an original, which is a light source for irradiating light onto the original surface. CIS (Contact Image Sensor) 10b for converting the image of the document into an electrical signal based on the element 10a and the reflected light reflected from the original picture, and CIS for driving control of the CIS 10b according to a predetermined control signal. It consists of the controller 10c.

Reference numeral 17 denotes a central processing unit (CPU) for controlling the operation of the entire apparatus, and 11 denotes temporarily storing image data input from the CIS 10b in accordance with a predetermined control signal from the central processing unit 17. Data storage unit as a volatile memory for storing, 12 is a program storage unit as a nonvolatile memory in which the operation program of the central processing unit 17 is stored, 13 is a data to be modulated image data to be transmitted to the other terminal or received from the other terminal The demodulation device for demodulating.

In addition, reference numeral 14 is a network control unit (NCU: Network Control Unit) for connecting with the trunk line communication network so that the data transmission and reception between the facsimile, 15 is for printing the image data received from the other fax on the recording paper when receiving the data. The printing section 16 is a display section for indicating the overall operating state of the fax.

That is, in the conventional facsimile having the above-described configuration, when the user inputs the number and start key of the relative facsimile terminal in the state where the document is set, the central processing unit 17 makes a counterpart through the network control device 14. The call connection with the facsimile terminal is performed. When the call between both facsimile terminals is established, the central processing unit 17 turns on the light source element 10a and simultaneously controls the CIS 10b through the CIS controller 10c to read an image. Will run On the other hand, when an original is inserted, the light source element 10a shines light on the original surface, and the CIS 10b signals the light reflected from the original surface by one scan line, which is decomposed by the scanning. The pixel information of the image is converted into binary data of "0" and "1" and stored in the data storage unit 11 in units of one scan line.

Subsequently, the central processing unit 17 reads the image data stored in the data storage unit 11 in a predetermined unit, converts the image data into an analog signal for trunk line transmission through the modulation and demodulation unit 13, and then adjusts the network. The device 14 is controlled to transmit to the other facsimile terminal. The other facsimile terminal receives and demodulates the transmitted data and drives the printing unit based on the demodulated data to reproduce an image such as an original image.

On the other hand, when the facsimile apparatus transmitted as described above is used for transmitting military or corporate secrets, the general facsimile apparatus is often printed as it is printed on the recording paper, the important confidentiality is often leaked.

Therefore, when the facsimile device is used for military use or in a company or a public institution, security is required when transmitting data of important contents.

Accordingly, the present invention was created in view of the above circumstances, and transmits the professional data together with the password in the facsimile apparatus and prints the received professional data only when the password matches the received number by inputting the password. The purpose of the present invention is to provide a security method of transmission data in a facsimile device that has security.

Determining whether or not the password match, judging whether the password matches, characterized in that it comprises a data output step of printing the stored professional data on the recording paper.

According to the present invention having the above-described configuration, the sender enters the password and then transmits the specialized data, and then the receiver also inputs the password so that the contents of the stored data are recorded on the recording paper only when the password matches the stored password. Will be printed.

Therefore, only the person who knows the contracted password can receive the contents of the transmitted data, thereby maintaining the security of the transmitted data.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.

2 is a block diagram illustrating an internal configuration of a facsimile apparatus for explaining a method of securing transmission data according to an embodiment of the present invention.

In FIG. 2, the same reference numerals are assigned to parts performing the same functions as those of FIG. 1, and detailed description thereof will be omitted.

In FIG. 2, reference numeral 20 is a key input unit having a numeric key 20b for inputting a password and an output key 20a for inputting a command for printing the contents of stored data, and 21 is an input password. A program storage unit for storing a program to print the contents of the received and stored data only when it matches the stored number, 22 is a password storage unit for storing the received password, 23 controls the overall operation of the facsimile apparatus according to the present invention It is a central processing unit for.

Next, the operation of the device having the above configuration will be described with reference to the operation flowchart shown in FIG.

Fig. 3A is an operational flowchart for explaining data transmission in the transmitting side facsimile apparatus having the above-described functions, wherein a document of data to be transmitted by the user is first inserted through the reading unit 10, and the receiving side facsimile apparatus is shown. When there is an input of a telephone number key button for dialing a telephone number of the user (step ST1), the central processing unit 23 transmits a DTMF signal corresponding to the key input button, thereby making a call connection with the other fax machine. (ST2 step).

Subsequently, when a call connection is made with the receiving side facsimile apparatus, the receiver receives a CFR (ConFirmation to Receive) signal for receiving data from the receiving side facsimile. Accordingly, the central processing unit 23 transmits a start signal for transmitting data. ) Is sent to perform a data transmission preparation step.

The data transmission preparation process is a CSI (Called) that transmits a telephone number and the like so that the central processing unit 23 can distinguish the transmitting station from the Digital Identification Subscriber (DIS) signal indicating that the communication is a communication complying with the CCITT specification by the receiving side fax. In addition to the Subscriber Identification (CSI) and CCITT regulations, NSF (Non-Standard Facilities) signals are sent to notify the recipient that it has its own code communication method.

On the other hand, a non-standard command (NSC) signal for the NSF, which is transmitted only to a facsimile of the same type as the digital transmit command (DTC) signal for the DIS signal, is received from the receiving side facsimile.

Thereafter, the central processing unit 23 sends a digital command signal (DCS) signal for determining a transmission / reception method to a receiving side fax, a TSI (Transmitting Subscriber Identification) signal for identifying a transmitting station, and a line state. TCF (Training Check) signal is sent.

In addition, in response to the central processing unit 23 receives the CFR (ConFirmaion to Receive) signal that may send data to complete the data transmission preparation.

On the other hand, when receiving a CNG (Calling) tone from the receiving side fax, there is an input of the password key button by the user who hears it. Therefore, when the password key button is input (step ST3), the central processing unit 23 sends the DTMF signal corresponding to the input password to the trunk line (step ST4).

After that, when a start key (not shown) is input by the user (step ST5), the CPU 23 controls the CIS controller 10c to scan the inserted data text through the CIS 10a. (ST6 stage).

Then, the scanned data is modulated by the modulation / demodulation device 13 and then sent to the trunk line through the network control device 14 (step ST7).

3B is an operation flowchart for explaining a data receiving process in the receiving side facsimile apparatus, and when receiving the DTMF data in the state connected with the transmitting side facsimile apparatus (step ST11), the central processing unit ( 23 stores the received DTMF data in the password storage unit 22 and switches the self mode to the control mode for storing the received data (step ST12).

However, if there is no DTMF reception in the state of being connected to the sending side facsimile apparatus, the central processing unit 23 performs a normal facsimile function of demodulating and printing the received data (step ST13).

On the other hand, when the data is received immediately after the reception of the DTMF data (step ST14), the central processing unit 23 demodulates the received data through the demodulation device 13 (step ST15).

Subsequently, the CPU 23 stores the demodulated data in the data storage 11 and indicates that there is data received through the display 16 (step ST16).

Meanwhile, when the output key 20a and the password of the key input unit 20 are input by the user who recognizes the display state of the display unit 16 after receiving the data (step ST17), the central processing unit ( 23 determines whether the input number matches the password stored and received in the password storage unit 22 (step ST18).

If the input password does not match, the central processing unit 23 displays an error message through the display unit 16 and ends (step ST19), and the input password is stored in the password storage unit 22. If it matches the password stored in the read data stored in the data storage unit 11 to print the contents received through the printing unit 15 on the recording paper and ends (ST20 step).

Therefore, only the person who knows the password can receive the received content, thereby maintaining the security of the transmitted data.

That is, according to the embodiment, when transmitting valuable data requiring security, a password that is not known to a general person is transmitted after it is transmitted, and even when such data is received, the password is received without inputting a password without being immediately printed. Only if it matches, will be printed on the record sheet so that only certain people who know the password can receive it.

In addition, this invention is not limited to the said Example, It can variously deform and implement within the range which does not deviate from the technical summary of this invention.

As described above, according to the present invention, a method of securing transmission data can be realized in a facsimile apparatus in which desired transmission data can be secured.
