Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote sign book system capable of remotely signing a document on one side of a communication terminal connected via a high-speed data transfer line from the other side. .

[0002]

2. Description of the Related Art A high-speed data transfer line such as ISDN is used for data communication, whereby a large amount of information, for example, image information can be transmitted to a remote place, so that a video conference system is realized. Has been done.

[0003]

By the way, if such a high-speed data transfer line can be used to remotely sign a document at the remote location without mailing the document, the document can be remotely controlled. It is convenient to save the time and effort of mailing and to obtain a signature immediately, and it is desired to realize such a signature entry system. The present invention, in response to the above-mentioned demand, transmits a signature information to a document on one side of a communication terminal connected by a high-speed data transfer line by remote control from the other side, and writes the document by mail. It is an object of the present invention to provide a remote signature entry system that can sign the document from a remote place without doing.

[0004]

In order to achieve the above object, the present invention is to connect a sending side and a receiving side communication terminal via a high-speed data transfer line, and to send a document on the receiving side to a remote side from the sending side. A signature entry system for signing by operation, wherein a communication terminal device on the sending side has an image display device for displaying an image transmitted from the communication terminal device on the receiving side and a character input device for inputting a signature character. The communication terminal on the receiving side is provided with an image pickup device for picking up an image of the document and a printing device for writing the character information input from the character input device and transmitted on the document.

[0005]

According to the above construction, the receiving communication terminal transmits the image information of the document imaged by the image pickup device to the transmitting communication terminal, and the transmitting communication terminal transmits the transmitted image information. Display on the image display device. The user inputs the signature character with the character input device while looking at this display. This input character information is transmitted to the receiving communication terminal and written on the document by the printing device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example of the operational configuration of a remote signing system according to the present invention. In this system, a communication terminal 1 on the transmitting side (referred to as a transmitting terminal) and a communication terminal 2 on the receiving side (referred to as a receiving terminal) are connected via an ISDN network 3 which is a digital high-speed data transfer line. The transmission terminal 1 has at least an image display device 4 such as a CRT or a liquid crystal display for displaying the image transmitted from the reception terminal 2.
(Referred to as CRT) and a character input device 5 such as a tablet or a light pen for inputting a signature character, and the receiving terminal 2 has at least an image capturing device 6 (camera) such as a television camera for capturing a document. , And a printing device 7 such as a plotter or a printer for writing the character information input and transmitted by the character input device 5 on the side of the transmission terminal 1 on a document.

FIG. 2 shows a specific configuration of the transmitting and receiving terminals 1 and 2.
Shown in Here, only one of the terminals is shown, and it is assumed that the transmitting side and the receiving side have the same configuration and both sides can achieve the function of the remote sign. Each terminal has a line control unit 11 that controls connection with the ISDN network 3.
And a device control unit 12 that controls the entire system according to a predetermined program, such as a microcomputer, and a CR
A display control unit 13 that drives T4, an image digital processing unit 14 to which an image pickup signal from the camera 6 is input, a print control unit 15 that controls the printing device 7, and a character that processes a signal from the character input device 5. Input processing unit 16 and I
It has a terminal confirmation unit 17 for mutually transmitting and collating D data.

The operation of this system will be described below. When the terminal confirmation unit 17 completes the terminal confirmation as described later, the receiving terminal 2 transfers the image information of the document imaged by the receiving camera 6 to the transmitting terminal 1 via the ISDN network 3. The image information of the documents sent is the CR of the sender
It is displayed and output on the screen of T4. On the sending side, the user inputs the character to be signed from the character input device 5, such as a tablet, while checking the image information. Information including the coordinate data of the input character is transmitted from the transmitting terminal 1 by the I
The data is transmitted to the receiving terminal 2 through the SDN network 3, and the printing device 7
Will be output. As a result, characters are written on the document. Further, the document in which the characters are written is imaged by the camera 6 and transferred from the receiving side to the sending side in the same manner as described above, and the CR
Display it again on the T4 screen. When the user confirms this, the signing of the signature is completed. Thus, since the target document can be visually confirmed and signed, it is possible to sign immediately even at a remote place without the trouble of mailing the document.

Further, the terminal confirmation unit 17 includes a device control unit 12
A collation unit that collates ID data with each other between the transmitting and receiving terminals 1 and 2 in response to an ID data generation and collation request instruction, and a random number generation unit that generates a random number in response to the ID data generation request. And a data memory for storing data. The terminal confirmation unit 17 collates and confirms whether or not the transmission and reception terminals connected to both ends of the data transfer line are legitimate with each other using ID data at an address based on a random number. The reason for providing such a terminal confirmation unit 17 is to prevent the information from being stolen or the system being used improperly because there are many confidential documents for signatures in this system. Is.

In the usual confirmation method using fixed ID data, password, etc., if these ID data, password, etc. are stolen, illegal use cannot be prevented and confidentiality cannot be maintained. Since different ID data is used every time the data is generated and the terminals collate and confirm each other, such a situation is prevented. Therefore, even if the user intercepts the coordinate data for the plotter of the printing device 7 during signing and tries to retransmit the data from another terminal, the data cannot be accessed. Therefore, unauthorized use of this system is prevented. It should be noted that the present invention is not limited to the configuration of the above-described embodiment, and various modifications can be made. For example, regarding terminal confirmation, this method has an advantage of surely confirming the validity of the terminal, but is not necessarily limited to this method. Not a thing.

[0011]

As described above, according to the present invention, a document is photographed by the image pickup device and displayed on an image display device at a remote place by using a high-speed data transfer line. By inputting with a device, sending back this information, and writing it on a document with a printing device, a document or the like can be signed by remote control. Therefore, it is possible to immediately sign the document from a remote place without mailing the document.
