[0002]

2. Description of the Related Art Conventionally, when a secret document is sent to a specific person by facsimile between head offices and branches in a company, in order to prevent others from seeing the document, the sending time is notified in advance by telephone. The recipient personally stood by the facsimile transceiver and took out the received documents directly.

Further, some facsimile machines themselves have a security function for encrypting important information.

[0004]

However, the above-mentioned method of notifying the transmission time by telephone has the inconvenience that the transmission cannot be performed unless the other party is present.

[0005] For a facsimile transceiver provided with a security function, the facsimile transceiver itself must be unified into its model, and it is inconvenient to replace the machine especially in an overseas branch office. There has been a problem that replacement of the facsimile transceiver is expensive.

The present invention has been made in view of the above points, and an object of the present invention is to provide a communication concealment device capable of keeping communication confidential by simply connecting to an existing facsimile transceiver. To provide.

[0007]

The communication concealment device of the present invention is connected between a telephone line and a facsimile transceiver, and identifies the destination code data sending means and the destination code data and the corresponding ID code. Identifying means and storage means for storing the data received from the facsimile transmission / reception device of the other party when the destination code data is received, in association with the destination code, instead of taking out the data as an image. When the data is identified, the data corresponding to the ID code stored in the storage means is taken out by the facsimile transceiver.

In the communication concealment device, the I
The D code is one of data read from a personal identification card, a personal identification number or data read from a bar code, or a combination thereof.

Further, the communication concealment device is provided with timer means for erasing the data received in association with the destination code after a predetermined period has elapsed from the time when the data was stored.

Further, in the communication concealment apparatus, when the data received in association with the destination code is stored, the destination code or the destination name corresponding to the code is issued to the facsimile transceiver.

Further, the communication concealment device is provided with display means for displaying a destination code corresponding to the data or a destination name corresponding to the code when the data is stored in the storage means.

[0012]

According to the communication concealment device of the present invention, the destination code data is transmitted to the telephone line before transmitting the communication data by operating the destination code data transmitting means.
When the receiving side identification means identifies the sent destination code data, the communication data is stored in the storage means in correspondence with the destination code without being output to the receiving side facsimile transceiver.

The data thus stored is not taken out as an image unless the identification means identifies the ID code, so that communication is not leaked to anyone other than the recipient.

As the above ID code, a personal identification card with a magnetic film attached, a personal identification number, or data read from a bar code can be used. Moreover, if the identity of the person is verified by using these combinations, the possibility of leakage of secrets is further reduced.

Further, the timer means can prevent the overflow of the storage means by deleting the data after a predetermined period has elapsed since the data received corresponding to the destination code was stored.

Further, when the received data is stored in association with the destination code, the destination code or the destination name corresponding to the code is output to the facsimile transceiver, or the data is stored in the storage means. By displaying the destination code corresponding to the data or the destination name corresponding to the code on the display means, it is possible to prompt the user to retrieve the received contents.
