Abstract

PURPOSE:To prevent illegal utilization by allowing a terminal equipment to apply registration/discrimination of a pass word in a VIDEOTEX system or the like. CONSTITUTION:The titled equipment is provided with a nonvolatile memory 1 storing a pass word, a keyboard 2 used for the setting/registration of the pass word, a switch 3 operated at the setting of the pass word and a microcomputer 4 controlling the nonvolatile memory 1, the keyboard 2 and the switch 3. In discriminating the pass word, the data inputted from the keyboard 2 and the pass word registered in the nonvolatile memory 1 are compared. When they are coincident, the succeeding operation of the terminal equipment is permitted and when dissident, the data is inputted again from the keyboard 2. In registering the pass word, the switch 3 allowed for the operation by the specific user only is turned on and the data inputted from the keyboard 2 is stored in the nonvolatile memory as the pass word. Thus, the pass word is changed by the specific user easily, then the piracy of the pass word is coped with by changing the pass word periodically. The processing above is executed easily without imposing a load onto the center.

Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATION FIELD OF THE INVENTION The present invention relates to an online terminal device such as a Videotex terminal that prevents unauthorized use.

In conventional Videotex systems such as the Technology Captain System, a password is set for each terminal device to prevent access from unregistered terminals or to limit the number of users of the terminal device. The terminal user is asked to enter a password, which is compared with the password registered in advance at the center, and the center determines whether access to the database is permitted or not.

Problems to be Solved by the Invention However, in the conventional configuration described above, the password is registered at the center and the password is determined at the center, so once the password is obtained, the terminal device cannot be used freely thereafter. The problem was that it could be done.

Means for Solving the Problems In order to solve the above problems, the present invention provides a non-luminous memory for registering and storing the password, a keyboard for inputting the password, and a switch for enabling the registration of the password. The password is registered and determined by a terminal device.

Function: By having the above-described configuration, the present invention allows the terminal device to determine the password, and also allows the password to be easily changed using the terminal device.

Example FIG. 1 shows the main parts of an embodiment of the present invention.

In Figure 1, 1 is a non-luminescent memory that stores passwords, 2 is a keyboard used for setting and registering passwords, 3 is a switch to be operated when setting a password, and 4 is a non-luminescent memory 1, keyboard 2, and switches. 3, and operates according to the flow shown in FIG. 2 when setting a password, and according to the flow shown in FIG. 3 when determining a password.

This will be explained in more detail below. First, when determining a password, as shown in Figure 2, the data entered from the keyboard 2 is compared with the password registered in the flash memory 1, and if they match, subsequent operation of the terminal device is permitted. , if they do not match, data entry from the keyboard 2 is performed again.

Also, when registering a password, by turning on the switch 3 that can only be operated by a specific user, the flow shown in Figure 3 will operate, and the data entered from the keyboard 2 will be stored as a password in the flash memory. let

Effects of the Invention As described above, in the present invention, the password is registered and determined in the terminal device, so that the password can be determined in the terminal device without imposing a load on the center. Also,
Since we have made it easy for specific users to change passwords, it is possible to protect against password leaks by changing passwords regularly, and it is easy to do so without putting a load on the center. can be done.

Claims (1)

[Claims] A non-luminous memory for storing a password, a switch for permitting the password to be registered in the non-luminous memory, a keyboard for inputting the password, and controlling the non-luminous memory, the switch, and the keyboard. The microcomputer compares the data entered from the keyboard with the password stored in the non-luminescent memory, and if they match, it permits the subsequent operation of the terminal device, and if they do not match, it inputs the password again. The online terminal device is in a state of waiting for an input, and when registering the password, by turning on the switch, the data input from the keyboard is registered in the non-luminous memory as the password.
