Abstract

A security server for facsimile machines to provide security information on users authorized to print document data transmitted from a transmitting facsimile machine to a receiving facsimile machine, to the receiving facsimile machine. The security server includes a security information storage to store the security information, a security server control to receive the security information from the receiving facsimile machine and to update the received security information into the security server control An interface controlled by the security server control transmits the updated security information to the receiving facsimile machine, in response to a request issued by the receiving facsimile machine via a security communication line different from a communication line that transmits the document data from the transmitting facsimile machine to the receiving facsimile machine. The security information includes identifications and passwords of the authorized users. Accordingly, it is possible to transmit or receive a document while transmitting or receiving security information and to make a plurality of receiving facsimile machines that use different protocols share the security information.

4. The security server of claim 2, wherein the security server control unit transmits the security information stored in the security information storage unit to the transmitting facsimile machine via the receiving facsimile machine, and the transmitting facsimile machine determines whether to authenticate the user or based on a result of comparing the user information received from the receiving facsimile machine with the received security information.

5. The security server of claim 2, wherein the security server control unit transmits the security information stored in the security information storage unit to the receiving facsimile machine, and the receiving facsimile machine determines whether to authenticate the unauthorized user based on a result of comparing user information input by a user attempting to print the document data, with the received security information.

6. A method of selectively printing document data using a security server for facsimile machines, which provides security information on users who are authorized to print document data transmitted from a transmitting facsimile machine to a receiving facsimile machine, to the receiving facsimile machine, the method comprising:

storing the security information;

transmitting the security information and the document data to the receiving facsimile machine;

receiving user information on a user attempting to print the document data;

authenticating the user based on a result of comparing the received user information with the security information; and

printing the document data if the user is authenticated,

wherein the security information is transmitted via a security communication line different from a communication line that transmits the document data from the transmitting facsimile machine to the receiving facsimile machine.

7. The method of claim 6, wherein the security information includes at least a plurality of identifications and passwords of the authorized users.

8. The method of claim 7, wherein the authenticating the user based on a result of comparing the received user information with the security information comprises:

providing the received user information to the security server for the facsimile machines; and

enabling the security server for the facsimile machines to determine whether to authenticate the unauthorized user based on a result of comparing the received user information with the security information and to inform the receiving facsimile machine of a result of the determination.

9. The method of claim 7, wherein the authenticating the user based on a result of comparing the received user information with the security information comprises:

providing the received user information to the transmitting facsimile machine; and

enabling the transmitting facsimile machine to determine whether to authenticate the unauthorized user or not based on a result of comparing the received user information with the security information and to inform the receiving facsimile machine of a result of the determination.

10. The method of claim 7, wherein the authenticating the user based on a result of comparing the received user information with the security information comprises:

providing the received user information to the receiving facsimile machine; and

enabling the receiving facsimile machine to determine whether to authenticate the unauthorized user or not based on a result of comparing the received user information with the security information and to inform the receiving facsimile machine of a result of the determination.

11. A computer-readable medium encoded with processing instructions implementing a method of selectively printing document data using a security server for facsimile machines, which provides security information on users who are authorized to print document data transmitted from a transmitting facsimile machine to a receiving facsimile machine, to the receiving facsimile machine, the method comprising:

storing the security information;

transmitting the security information and the document data to the receiving facsimile machine;

receiving user information on a user attempting to print the document data;

authenticating the user based on a result of comparing the received user information with the security information; and

printing the document data if the user is authenticated,
