Abstract

PURPOSE:To protect an ID or a password by providing password number input function which is needed to use a communicating device. CONSTITUTION:For a password number to be inputted according to a message from the password number input requesting means A, coincidence with the password number to be registered is checked by a collating means B. When the password numbers are not coincident, a discordance number is stored in an input number memory 14 and a re-input is requested to the means A. The maximum number of the input number is set to a program 5 for communication in advance. When this setting value is coincident to the value of the memory 14, the password number is stored in a collated result 15 as the discordance. A CPU 1 observes the contents of the result 15 and when the password numbers are coincident, this communicating device can be used.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention provides information necessary to use this communication device in order to protect the ID and password of the information device user in communication using the information device. The present invention relates to a communication device for inputting a password.

[Conventional technology]

Conventional communication devices did not have such a function, and there was a risk that someone else could see your ID and password.

[Problem that the invention seeks to solve]

When you try to connect to a certain network using an information device, some communication devices automatically make a call to that network, and once the call is connected, you need to make a user-specific call to receive the service of that network. There are some that automatically enter your ID and password. In such communication devices, it is necessary for the user to register his/her own ID and password in the memory of the communication device in advance. This content is visible to anyone using the communication device so that it can be changed later. Therefore, there is a risk that someone else can see your ID and password, which could lead to misuse.

This invention was made to solve the above-mentioned problems, and its purpose is to protect IDs and passwords by providing a password input function necessary for using a communication device.

[Means for solving problems]

In order to protect the ID and password of an information device user, this invention provides a means for requesting input of a PIN number necessary for using a communication device, and a means for requesting input of a PIN number necessary for using a communication device, and a means for requesting input of a PIN number that is inputted or matched with a pre-registered PIN number. The present invention is characterized in that it has a password verification means for checking whether the inputted number is a registered password, and a processing means when the password does not match when the input number does not match a pre-registered password.

〔Example〕

Hereinafter, one embodiment of the present invention will be explained using the drawings.

FIG. 1 is a block diagram of a communication device according to the present invention. 1 is a CPU of the main body of the communication device. 2 is a communication equipment control program. 3 is a screen of the communication device, which displays transmitted or received document data. 4 is an input keyboard of the communication device. 5 is a communication program, and communication is performed by this program. 6 is a data transmission circuit through which data is transmitted to the outside. 7 is an external storage device such as a floppy disk or a hard disk, and the password information of 8 and the ID and password information of 9 are stored. The password No. 8 is used to check whether the person using this communication device is qualified to view the registered ID and password information.

The ID and password information in No. 9 is assigned to each user on an individual basis for each network, and in order to receive network services, this ID and password must be input into the network. 10 is RAM, in which 11 passwords, 1
2 ID, password information, 13 input number memory, 1
There are 4 matching results. 11.12 is the one loaded from 8.9 in the external storage memory of 7 into the RAM by the communication program when the communication program is started, and can be changed because it is on the RAM. The input number memory 13 is a memory for storing the numerical value input by the user from the keyboard 4 as a password.

The input circuit memory 14 is a memory that requests re-input if the entered password does not match the registered password, and records the number of times the password does not match. 15 is a memory that finally stores the result of whether the input password matches the registered password.

A is a password input requesting means, which displays a message "Please enter your password" on the screen of the communication device 3 using the communication program 5. B is a password verification means, which checks whether the password input according to the message from A matches the password registered in 11. If there is a match, the information is 1
Stored in the matching result of 5. For example, a method may be used in which 1 is written into the memory of the verification result. If they do not match, the number of times they did not match is stored in the input number memory 14, and the process returns to the password input requesting means A to request re-input. The maximum number of inputs is preset in the communication program 5, and the user is requested to re-enter the password until the set value matches the value in the input number memory 14. If the set value matches the value in the input count memory 14, it is determined that the passwords do not match, and the result is stored in the verification result 15. For example, a method is used in which 0 is written into the memory of the verification result. C.P.
U looks at the contents of the verification result in step 15, and if the passwords match, the communication device can be used normally, so the communication program in step 5 moves on to the next process. If the PIN numbers do not match, the PIN number 11 and the ID number 12 on the RAM are stored by C's PIN number mismatch processing means.
Delete password information. Thereafter, the communication program No. 5 moves on to execution of the next process.

This way, your ID and password will not be seen by others, making it safe.

FIG. 2 is a diagram showing a password input screen by the communication device of the present invention. In the example of FIG. 2, it is assumed that the password number is four digits. A is a password input request screen, and b is a screen during which the password is being input. 16 is a message requesting input of a password, and 17 is a mark indicating the position where the numbers of the password are to be entered. In FIG. 2, four marks such as 17 are displayed because the password requires four numerical values. 18 is a mark indicating whether the currently input number is the same digit of the password. For example, if the first digit of a password is entered from the keyboard, the leftmost of the 17 marks on the screen will be replaced by another mark such as 18. It is also not desirable for others to see the password, so even if the password is entered from the keyboard, it is converted to a mark such as 18 and displayed.

FIG. 3 is a diagram showing a flowchart of the password input request program of the present invention. 19 is a process for setting the number of inputs to zero. The number of inputs is incremented if the input result does not match the registered password, so it is initialized to 0 at the beginning of the program. Reference numeral 20 indicates a message requesting the input of a personal identification number, and a screen as shown in FIG. 2 is displayed. 21 is a password input performed by the user according to the message 20. 22 is a process for displaying a PIN input mark as shown in FIG. 2, which is displayed according to the PIN input; 23 is a check to see if the input PIN matches a pre-registered PIN. If there is a match, the process moves to step 27. In step 27, contents indicating a match are written into the matching result memory on the RAM.

If the passwords do not match, the number of inputs is rewritten to 24. Here, in order to remember the current number of inputs, 1 is added to the previous value. 25 checks whether the value in the input count memory matches the allowable input count defined on the communication program. If they do not match, the number of inputs is less than the allowable number of inputs, so the screen branches to display a message requesting PIN number 20 to be re-entered. If it matches, 2
Proceed to step 6. In step 26, the content indicating that there is no match is written into the matching result memory on the RAM.

〔Effect of the invention〕

As described above, the present invention makes it possible to input the PIN number required to use the communication device in order to protect the ID and password of the information device user in communication using the information@device. did.
