Abstract

PURPOSE: To eliminate the need for time matching, to enhance the security without increasing number of digits and to improve the propriety of use by storing a keying state of a character and a numeral or the like in the case of storing a password. CONSTITUTION: A key matrix section 7 is used to set a destination telephone number, to set a password and to enter the password, and a registration section 8 stores the set password. In this case, the registration section 8 stores the sequence of the password and the keying state. Then an entry analysis section 9 compares the entered password with a password set in the registration section 8 to compare the entry sequence of them and compares the keying state of the key matrix section 7. When the entered password is coincident with the password set in the registration section 8 as a result of the comparison, the section 9 gives an enable signal to a control section 5 to permit the operation such as dialing. When the entry analysis section 9 discriminates dissidence, the section 9 gives an inhibit signal to the control section 5, which disables the availability of a portable telephone set.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a password verification system, and more particularly to a wireless selective call receiver with a display which can be used in a plurality of regions.

[0002]

2. Description of the Related Art Conventionally, in a portable wireless communication device such as a mobile phone, a personal identification number or a password is set so that it cannot be used by anyone other than the owner of the wireless communication device without permission. By setting the password in advance by the owner, communication cannot be performed using the wireless communication device unless a password matching the set password is input when using the wireless communication device.

As for such a password, the greater the number of combined characters or numbers, the lower the possibility of being understood by a third party, but the more difficult it becomes for the owner to remember the password. In particular, a portable wireless communication device is very inconvenient because it is necessary to carry a device in which a password is written unless the password is stored.

Therefore, 3- or 4-digit characters or numbers are used as this type of password.

On the other hand, this type of password is also used in information equipment. Then, not a simple combination of letters or numbers, but a method of utilizing a time interval for inputting a password is disclosed in, for example, Japanese Patent Laid-Open No. 63-23166.
No. 6 or Japanese Patent Application Laid-Open No. 5-27861.

In the password collation method for these information devices, whether or not the password matches is determined by whether or not the time from the input of the nth character to the input of the (n + 1) th character is within the allowable range. To be done. For example, if the time from the input of the first character to the input of the second character is shorter or longer than the predetermined allowable range, the second character does not match the password even if it is a correct character. Is judged.

As described above, by monitoring the input sequence of passwords and the input time interval between each character, it is possible to enhance security without increasing the number of digits of the password.

It is possible to use the password verification method used for this kind of information equipment in a portable radio communication device.

[0009]

However, in such a password collation method, the input sequence of passwords and the element of the input time interval are added, so that the owner needs to sensuously perform an appropriate timing of pressing the passwords. There is.

Further, since the input time interval is a time factor, there is a problem that the password input time is extended.

The object of the present invention is to solve the above-mentioned problems,
It is to provide a password verification method that does not include a time factor in password verification.

Another object of the present invention is to provide a password collation method which eliminates the need for the timed timing of password input, enhances the security protection without increasing the number of digits of the password, and improves the convenience of use. To do.

[0013]

In order to achieve the above-mentioned object, the password collation system according to the present invention has a storage means for storing keystroke states such as characters and numbers of a password.

Further, there is provided comparison means for comparing the keystroke state of the password stored in advance with the keystroke state of the inputted password.

Furthermore, as a result of the comparison, if they do not match, the security state is maintained.

[0016]

By adopting the above-mentioned configuration, the password collation method according to the present invention compares the order of inputting the passwords and the keystroke state in the input, so that the password collation does not include a time factor, and the user does not There is no need to consider temporal timing with respect to input.

Further, there is no delay in inputting the password.

Further, it is possible to enhance security and improve convenience of use without increasing the number of digits of the password.

[0019]

The present invention will be described in detail with reference to the drawings.

FIG. 1 is a functional block diagram of a mobile phone showing an embodiment of the present invention.

In FIG. 1, the mobile phone includes an antenna 1,
Wireless unit 2, voice signal processing unit 3, transmission / reception unit 4, control unit 5,
It is composed of a display unit 6, a key matrix unit 7, a registration unit 8 and an input analysis unit 9.

First, the operation of the mobile phone of the present invention will be described.

The radio section 2 transmits and receives signals via the antenna 1. The voice signal processing unit 3 converts the received signal into a voice signal and supplies the voice signal to the speaker of the transmitter / receiver unit 4. Further, the voice signal processing unit 3 converts the voice from the microphone of the transmitter / receiver unit 4 into a transmission signal and supplies the transmission signal to the wireless unit 2. The control unit 5 controls the wireless unit 2 and the audio signal processing unit 3.
Since the operation of transmitting and receiving these signals is the same as the operation generally performed, not the gist of the present invention, detailed description thereof will be omitted.

The key matrix section 7 is used for inputting the telephone number of the other party, and is also used for setting the password and inputting the password. The registration unit 8 stores the set password. At this time, the registration unit 8
Stores the keystroke state as well as the password order.

The input analysis unit 9 compares the input password with the password set in the registration unit 8. here,
The input order of the passwords is compared, and the keystroke state of the key matrix unit 7 is also compared as described later. When the input password and the set password match as a result of the comparison, a permission signal is supplied to the control unit 5 to enable operations such as calling. When the input analysis unit 9 determines that they do not match, a prohibition signal is sent to the control unit 5, and the mobile phone is disabled. Therefore, no operation such as calling is performed.

If they do not match, the control unit 5 displays the display unit 6.
An error message or the like may be displayed on.

Next, the password collation method according to the present invention will be described in detail with reference to FIGS.

FIG. 2 is an operation sequence of password input according to the present invention, and FIG. 3 is a flow chart showing control relating to the determination of password match / mismatch according to the present invention.

In FIG. 2, the preset password is four digits in the order of "1, 2, 3, 4".

First, when the "1" key of the key matrix section 7 is pressed, the first keystroke state (state) is entered. That is, only the "1" key is pressed as the first digit. When the first digit password and the keystroke state match, the state of waiting for the input of the next digit, that is, the acceptance state of the next password (the state) is entered.

Next, if the "2" key in the second digit is pressed while the "1" key is still pressed, the keystroke state becomes. If the second digit password, ie, "2", and its keystroke state, ie, the depressed state of "1" and "2", match the state of waiting for the third digit input (
State).

In the state of, that is, when the second digit is input,
If "2" is not pressed, or if "2" is pressed without pressing "1", it is determined that they do not match and the state does not shift to the next state.

In the third digit password acceptance permission state,
If the "3" key is pressed while the "1" key is pressed, the third digit keying state is set. here,
When it is determined that they match with each other, a state of waiting for the input of the fourth digit is entered.

When the last 4th digit key "4" is pressed while the "1" key is not pressed, 4
It is (the state of) the keystroke state of the digit. At this time, "4"
If a key other than "1" is pressed, or if "4" is pressed while "1" is pressed, it is determined that they do not match.

The control relating to the determination of the above embodiment will be described with reference to the flowchart of FIG.

Input of the nth digit (n = 1, 2, 3, ...)
At (step 101), it is determined whether the entered passwords match (step 102). If it is determined that the passwords do not match, that is, if the matched password is not input, it is determined that the password fails (step 1).
06).

When the passwords match, it is determined whether the keystroke states match (step 103). Even if the passwords match, it may be determined that they do not match (step 106) by determining whether the password is pressed at the same time as another key.

When the keystroke states match in step 103,
Next, it is determined whether the number of input digits matches the number of digits of the password (step 104). In the above-mentioned embodiment, since the password is a four-digit password, if the fourth digit is the same, all passwords are judged to be acceptable (step 10).
5).

Here, the input of the second digit "2" key will be specifically described.

When the "2" key is pressed during the input of the second digit (step 101), it is first judged whether or not it matches the second digit of the password registered in advance (step 102). . Since the "2" key matches the second digit of the password, the keystroke state at the time of inputting the "2" key is next determined (step 103).

When the "2" key is pressed, if the "1" key is also pressed (state of FIG. 2), it is determined that the keystroke states are the same and it is not the fourth digit of the password ( (Step 104) The input acceptance state (state) of the third digit is set (step 101).

For example, if the "1" key is not pressed when the "2" key is pressed, it is determined that the keystroke states do not match, and the determination result is "fail".

As described above, not only the order of the passwords but also the keystroke state in which the passwords are pressed is taken into consideration to determine whether the passwords match. This allows
Security can be increased.

FIG. 4 is a flow chart showing the control in the input analysis unit of the present invention.

First, the number of digits N of the key to be input (N is a positive integer) is set to n = 1 (n = 1, 2, 3, ...) (step 201), and the first digit key is input. (Step 202). When the first digit key is pressed in step 202, it is determined whether the pressed key matches the first digit of the password registered in advance (step 203).

When it is determined that they match, it is determined whether or not the keystroke state at the input of the first digit matches the keystroke state of the password registered in advance (step 204). If it is determined that they match, N = n + 1 is set (step 205). Since n = 1 now, N = 2. Then, the digit number k (k =
(1, 2, 3, ...) And N are compared (step 20).
6). For example, if k = 4, (N = 2) ≠ (k =
4), the processes of steps 202 to 205 are repeated until N = 4.

When N = k in step 206, the coincidence signal is supplied from the input analysis section 9 to the control section 5 (step 207). In response to the coincidence signal, the control unit 5 turns on the mobile phone and enables operations such as a calling function and calling of a memory dial. For example, power is supplied to the wireless unit 2 and the audio signal processing unit 3.

On the other hand, if it is determined that the discrepancies occur in steps 203 and 204, a discrepancy signal is supplied from the input analysis section 9 to the control section 5 (step 209). In the control unit 5,
In response to the mismatch signal, an error message or the like is displayed on the display unit 6 and the operation of security protection of the mobile phone is continued. This prohibits calling the memory dial,
Prohibition of calling function is achieved.

If no key input is made in step 202, it is judged whether or not a predetermined time t has passed (step 208). When the time t has passed, a mismatch signal is sent (step 209).

In the above-mentioned embodiment, the mobile phone has been described, but the present invention is not limited to the mobile phone and can be used for other communication equipment or information equipment.

[0051]

As described above, the password collation method according to the present invention compares the order in which passwords are entered and the state of keystrokes at the time of inputting the characters and numbers of each password, so that the password input time It is possible to improve the convenience by eliminating the need for dynamic timing, enhancing the security protection without increasing the number of digits in the password.
