Description

Facsimile Security Methods

The present invention relates to a security method of a facsimile, and more particularly, in a facsimile employing a remote after service (Remote A / S) method, by storing unique information about the terminal of the other party connected to the facsimile, It is about a method of security of a facsimile that can cope with the leakage of information to the outside.

In addition, the present invention prevents the leakage of various information of the facsimile by forcibly canceling the current connection state when the control and information data transmitted from the other party's terminal does not include the unique information of the other party. It is about the security method of the facsimile.

In general, when a failure occurs in a corresponding product while a consumer purchases and uses the product, the after-sales service (hereinafter, abbreviated as 'A / S') is requested to the seller or manufacturer of the corresponding product. In this case, the distributor or manufacturer who receives the after-sales service sends a technician to the customer who requested the after-sales service, and the technicians directly operate the equipment to identify the cause of the failure and repair the product.

However, as the after-sales of the product has increased rapidly, it is difficult for the manufacturer and the sales company to secure a technician dedicated to the after-sales service, and if a technician is obtained, a huge labor cost is required. . In addition, as the technician takes a long time to move to the location where the corresponding product is installed, it is difficult to guarantee a quick after-sales service, thereby causing serious problems such as deterioration of recognition of the manufacturer and the seller.

In order to solve the above problems, recently, a remote A is used to identify a failure state of a corresponding product by using a terminal (usually, a 'host computer') connected to communicate with the corresponding product and to perform first aid. / S method was introduced, and the manufacturer executes remote A / S with the A / S dedicated program of each manufacturer for the corresponding product produced and shipped by the company. At this time, communication between the terminal of the manufacturer and the corresponding product is possible by a public switching telephone network (PSTN). In particular, since a product using a general telephone network such as a facsimile is more convenient to perform remote A / S, remote A / S is widely used in a product such as a facsimile.

However, according to the conventional remote A / S as described above, the following problems occur.

(1) In case of remote A / S-only program, it uses public communication line (regular telephone network), so if the person with unpleasant purpose has secured A / S-only program, customer information stored in the same type of facsimile is acquired. This is an important obstacle to the security of the fax.

(2) A person with an A / S-only program may paralyze the facsimile's function through an open communication line (general telephone network) for uncomfortable purposes, and the user has no countermeasure.

(3) If a person with an unpleasant purpose has acquired the user's personal information, the user and manufacturer cannot obtain information about the person who leaked the information.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is that any person connected to the facsimile, if a person with an unpleasant purpose wants to leak the user's personal information or paralyze the user's corresponding facsimile. It provides a security method of the facsimile to obtain the personal information about the information leaker by storing the unique information about the device of the device and display it according to the user's request.

In addition, another object of the present invention is to provide a security method of the facsimile to protect the user's personal information and the operating state of the device from those who have an unpleasant purpose in accordance with the above object.
