Abstract

PURPOSE:To improve the safety of a password by performing processing LOGON to check the qualification for connection of a terminal in accordance with a user ID and the password and processing LOGOFF to write the password inputted at the time of connecting the terminal. CONSTITUTION:Processing LOGON 2 is started at the time of supply of a command LOGON from a terminal connection keyboard 1b and reads in the user ID. When this user ID is registered in a password table 4, processing LOGON 2 collates the password read in by a magnetic card reader 1a with passwords set in the password table 4 to check the qualification for connection of a terminal equipment 1. When the terminal equipment 1 is disconnected, processing LOGOFF 3 writes the new password, which a user inputs from the keyboard 1b, in the password table 4 and the magnetic card.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method of checking the connection qualification of a terminal using a magnetic card in a computer system to which a large number of terminals are connected.

Conventional technology Traditionally, passwords have been used to check the connection qualifications of terminals, but in many cases, passwords have been registered in the system in advance and the passwords have to be entered manually when connecting the terminal, or the passwords have been input from the system. This is a method in which you manually respond to inquiries regarding passwords.

Problems to be Solved by the Invention As mentioned above, it is cumbersome to enter a pre-registered fixed password every time a terminal is connected, and passwords are generally made with a certain number of characters or more to prevent duplication and prevent accidental disclosure. There is also a risk that users may forget their passwords, or that their passwords may be intercepted without them noticing.

The present invention has been made in view of the above-mentioned conventional situation,
Accordingly, an object of the present invention is to provide a novel terminal connection qualification check method using a magnetic card, which makes it possible to solve the above-mentioned problems inherent in the conventional technology.

Means for Solving the Problems In order to achieve the above object, the terminal connection qualification checking method using a magnetic card according to the present invention maintains the correspondence between the terminal user ID and password created at the time of system generation. A password table, a magnetic card reading device for reading a password from a magnetic card held by an unused user when a terminal is connected, a LOGON process for checking the connection qualification of the terminal from the user ID and password, and when the terminal is disconnected. L for writing the new password entered by the user into the password table and magnetic card
It is configured to include an OGOFF process and a magnetic card writing device for writing a password on a magnetic card.

EXAMPLE Hereinafter, a preferred embodiment of the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a terminal connection qualification check method using a magnetic card according to the present invention.

An embodiment of the present invention includes a terminal device 1 including a magnetic card reading device la, a keyboard 1b, a display 1c, a magnetic card writing device fld, a LOGON processing 2, and a LOGON processing 2.
It consists of an OGOFF process 3 and a password table 4.

The password table 4 is a table for managing the correspondence between user IDs and passwords, and is created when the system is generated.

The operation of each means in this embodiment will be described in detail below.

First, referring to FIG. 2, LOGON processing 2 is started when the LOGON command is input from the keyboard 1b after the terminal is connected, and first, as shown in step 11, the LOGON processing 2 is started.
User I input as a parameter of the GON command
Read D0 Next, as shown in step 12, check whether the read user ID is registered in the password table 4. If not, proceed to step 1.
As shown in 8, a connection failure message is output to the user and the connection is refused. If it is registered, as shown in step 13, it is checked whether a password corresponding to the user ID has been set, and if it is not registered, a terminal session is opened as shown in step 17. Also, if a password has been set,
As shown in step 14, the password is read from the magnetic card, and as shown in step 15, it is checked whether the password has been obtained. If not, step 18 is executed. If successfully obtained, step 16
As shown in FIG. 3, it is checked whether the obtained password matches the password set in the password table 4, and if they do not match, step 18 is executed. If they match, step 17 is executed.

Next, referring to FIG. 3, LOGOFF processing 3 is started when a LOGOFF command is input from the keyboard 1b, and first, as shown in step 19, reads the password input as a parameter of the LOGOFF command. Next, as shown in step 20, If a password has not been specified, the terminal session is closed as shown in step 23. Also, if specified, step 21
As shown in step 22, the read password is written on the magnetic card, and the password is also set in the password table 4 as shown in step 22.
Block the terminal as shown in 3.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, the present invention not only eliminates the need to memorize long passwords, but also prevents unexpected disclosure when passwords are entered.
