Abstract

The present invention relates to a method in which only a corresponding user can listen to an incoming message recorded in a facsimile device having a built-in answering device (hereinafter referred to as a built-in TAD). In a facsimile device including a responder, a method of protecting private content includes the steps of: allocating an area of voice memory in the built-in answering machine for each user; Transmitting an index assigned to each user when a ring signal input from the outside is detected; Recording an incoming message when a corresponding index of a user who wants to leave a message is input; The recorded message may be reproduced only when a corresponding user's password is input.

How to Protect Private Content in Fax Machines with Built-in Answering Machines

The present invention relates to a method in which only a corresponding user can listen to an InComming Message recorded in a facsimile device having a built-in answering device (hereinafter referred to as a built-in TAD).

In general, if the TAD or TAD built-in facsimile device is set to answer mode, when externally calling, the TAD or TAD built-in facsimile device will connect the line and send OGM (Out Going Message). In addition, Beep will record the ICM (InComming Message). Basically, this type of operation is followed, but the recorded ICM has a disadvantage that it is not easy to be exposed from others. That is, in order to listen to its own ICM, it is necessary to listen to the entire ICM.

An object of the present invention for solving the above-mentioned problems is to provide a method in which only a corresponding user can listen to an incoming message in a facsimile apparatus having a built-in answering machine.

Another object of the present invention is to provide a method for preventing the infringement of the private contents of each user when multiple people share a facsimile device having a built-in answering machine.

2 is a flowchart sequentially illustrating a process for recording an incoming message according to a first embodiment of the present invention;

3 is a flowchart sequentially illustrating a process for reproducing the recorded incoming message according to the second embodiment of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, it should be noted that like elements and parts in the drawings represent the same numerals wherever possible.

1 is a schematic block diagram of a facsimile apparatus to which the present invention is applied.

Referring to FIG. 1, the central processing unit 110 controls the facsimile overall according to a program of a set mode. The network control unit 112 forms a communication path between the public telephone network (PSTN) and the modem 114 under the control of the central processing unit 110. The modem 114 demodulates an analog signal input through the network controller 112 into a digital signal under the control of the central processing unit 110, and converts the digital signal provided from the central processing unit 110 into an analog signal. Modulate with a signal. When the transmission or copy mode is set, the scanner 124 scans the supplied document under the control of the central processing unit 110, converts the document into image data, and provides the scanned data to the central processing unit 110. The printer 122 prints the received data or data to be copied under the control of the central processing unit 110. The operating panel 116 is composed of key metrics including a plurality of numeric keys and function keys for setting a function, and provides the central processing unit 110 with key data generated according to a key operation. do. In addition, the operation panel 120 is provided with a display unit for displaying the current operating state of the fax under the control of the central processing unit 110. The memory unit 120 temporarily stores data received when there is no recording paper in the reception mode or a specific function is set under the control of the central processing unit 110. The built-in TAD 118 also includes a voice controller and a digital voice memory, and is controlled by the CPU 110.

Typically, unless the TAD is capable of detecting DTMF (Dual Tone Multi Frequency), the recorded ICM should be designed to allow playback after inputting a password.However, the TCM or facsimile apparatus capable of detecting DTMF may use the ICM storage area. It should be divided among several users and designed to allow each user to play recorded ICM for their own area.

In the present invention, a facsimile apparatus having a built-in modem capable of detecting DTMF will be described as an example.

The built-in TAD applied to the present invention should include a voice controller and a digital voice memory. First, as shown in the flowchart shown in FIG. 2, the person who wants to use the facsimile in the response mode first records the OGM. It is recommended that the contents of the OGM be as follows.

.... If you want to leave a message on the device, enter the two-digit code of the person who will hear the beep and say 'A' is' *, 1 ',' B 'is' *, 2' and 'C' is' * , 3 '.

When a ring signal input from the outside is detected 201, a communication path is formed, and the central processing unit 110 operates the built-in TAD 118 to transmit the OGM stored in the built-in TAD 110 (202). Then, it is configured to detect a tone flowing through the modem 114 (Configuration), and waits for detecting a DTMF '*' or a fax tone.

If the caller inputs '*, 1' (203), the central processing unit addresses the voice memory of the recording area, records the area of 'A' in the ID information area, and then records the ICM ( 204). The memory configuration of the ICM area stored in this way is stored in the form shown in Table 1 below.

As shown in Table 1, when performing playback and addressing of each stored ICM, if the playback is performed using the operation panel unit 116 shown in FIG. 3, the play button 301 is pressed. Only when the password is input 302, the content corresponding to O1 in the ID information area will be played back (303).

In this way, ICM can be divided and used to protect private and important contents from others using password.

ID information area index Date and time ICM message Flag 01 01 9-20 10:00 010011110110000011 ... FFh 01 02 9-20 10:20 010011100110110011 ... FFh 02 01 9-20 12:00 010011010110000011 ...

As described above, the present invention has the advantage that only the corresponding user can listen to the incoming message in the facsimile apparatus having a built-in automatic answering machine. In addition, the present invention has the advantage of preventing the infringement of the private content of each user when multiple people share the fax device having a built-in answering machine.
