DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio communication terminal, and more particularly to an improvement in the security of a radio communication terminal.

[0002]

2. Description of the Related Art A wireless communication terminal is convenient to carry, but has a security problem because it is easily stolen or used without permission. For example, even a person who is not the owner can easily perform transmission by operating the transmission button of the wireless communication terminal, so that there is a risk that a large amount of loss will be incurred if the device is stolen or used without permission.

Recently, techniques for providing a security function by collating a user's fingerprint have been proposed in various fields (for example, see Japanese Patent Application Laid-Open Nos. 5-344217 or 4-348408). . It identifies a user by checking the fingerprint of the user at the time of turning on the power of the device or at the start of work.

For example, as shown in FIG. 4, a finger of a hand 21 is placed on a fingerprint input scanner 22, and after the fingerprint collation is completed, the wireless communication terminal 23 is held and the communication button 24 is pressed to perform communication. It is also considered to do.

[0005]

However, if the wireless communication terminal is deprived after the owner has once turned on the power or started communication, the owner is not turned off until the power is turned off or the communication is terminated. It can be used even by people other than.

[0006] Therefore, an object of the present invention is to provide a wireless communication terminal having an advanced security function in which fingerprint collation of a user is constantly performed during use, and only a specified user can use.

A fingerprint storage unit that stores the crest and always on the user's finger during use
Using the opposing operation unit and the fingerprint of the finger opposing the operation unit
A fingerprint capturing unit for capturing as a user fingerprint,
A fingerprint that matches the user's fingerprint to identify a match or mismatch
Condition that a finger is opposed to the crest identification unit and the operation unit
Communication as the registered fingerprint and the user fingerprint
And a communication unit for ending the communication when does not match,
The operation unit is a communication device that is pressed by the middle of the finger of the user's hand.
A communication button, and the fingerprint capturing unit has a communication button.

FIG. 1 is a schematic perspective view of a radio communication terminal according to a first embodiment of the present invention when it is used. The wireless communication terminal indicated by reference numeral 1 is of a size that a user can hold with one hand, and includes a communication button 2 as an operation unit on a side surface of a housing. The communication button 2 is located at a position where the finger 3 of the user holding the wireless communication terminal 1 is applied. The fingerprint input scanner 4 is integrated with the communication button 2 so as to be able to input a fingerprint of the finger 3. The communication button 2 is urged outward by a spring 5, but activates the communication switch 6 when pushed inward by the finger 3.

FIG. 2 is an explanatory diagram of the configuration of the wireless communication terminal shown in FIG. At the same time as the finger 3 presses the communication button 2, a fingerprint image is formed on the two-dimensional CCD 7 of the fingerprint input scanner 4,
The fingerprint capturing unit 8 captures the fingerprint image as a user fingerprint, the fingerprint identification unit 9 compares the user fingerprint with the registered fingerprint, and if they match, sends a communication permission signal 12 to the communication unit 10.

This will be described in more detail. The user's finger 3 is in contact with the communication button 2 of the wireless communication terminal. The communication switch 6 is activated after the communication button 2 is pushed and moved by the finger 3 to obtain elasticity via the spring 5. By seeing the operation of the communication switch 6, the control unit 11 detects that the user has a communication intention.

The control unit 11 supplies a fingerprint capturing signal 12 to the fingerprint capturing unit 8 and captures a fingerprint image of the finger 3 formed on the two-dimensional CCD 7 of the fingerprint input scanner 4 as a user fingerprint.
The captured user fingerprint is collated by the fingerprint identification unit 9 with the fingerprint of the user registered in advance, that is, the registered fingerprint.
Here, it is assumed that the registered fingerprint is stored in the fingerprint identification unit 9. Therefore, the fingerprint identification unit 9 also functions as a fingerprint storage unit.

If the user's fingerprint matches the registered fingerprint,
The fingerprint identification unit 9 gives a communication permission signal 13 to the communication unit 14,
Allow communication. In response to the communication permission signal 13, the communication unit 14 performs communication by known means.

When the finger 3 is released from the communication button 2, the communication button 2 returns to the original position by the spring 5 and the operation of the communication switch 6 is released, so that the fingerprint capturing signal 12 from the control unit 11 disappears. The user's fingerprint is not captured. Therefore, in this state, since the communication permission signal 13 is not output, the communication unit 14 ends the communication.

Normally, a state where the communication button 2 is kept pressed is defined as a communication state. During this communication state, capturing of the user fingerprint and collation between the user fingerprint and the registered fingerprint are performed in a timely manner.

As described above, the communication is terminated when the finger 3 is released from the communication button 2, but is not immediately terminated when the finger is switched to another person while being kept maliciously pressed and the finger is replaced. However, since a mismatched result is obtained in the fingerprint matching performed in a timely manner, the fingerprint matching unit 9 stops giving the communication permission signal 13 to the communication unit 14 in response to the mismatch. Therefore, the communication unit 14 ends the communication.

When another person uses the communication from the beginning, even if the user presses the communication button 2 to start communication, the fingerprint does not match the fingerprint registered in advance by the fingerprint collation unit 9. And communication is not started.

FIG. 3 is a schematic perspective view when a wireless communication terminal according to a second embodiment of the present invention is used. In this wireless communication terminal, a communication button 2 and a fingerprint input scanner 4
Are formed separately, and are arranged at mutually different positions on the side surface of the housing. More specifically, the communication switch 4 is pressed with the belly 3-1 of the finger 3 supporting the wireless communication terminal 5 at this time.
The fingerprint scanner 3 is arranged at a position corresponding to 2. This also makes it possible to always collate the fingerprint during communication.

In the above description, the operation of the communication switch and the collection of the fingerprint are performed using the same finger, but a different finger may be used for the action.

In the above description, it has been described that the fingerprint identification unit 9 stores the registered fingerprint. However, the fingerprint identification unit 9 is configured to store the registered fingerprint in a fingerprint storage unit connected thereto separately from the fingerprint identification unit 9. Of course, it may be possible.

[0023]

As described above, the wireless communication terminal according to the present invention collates the fingerprint of the finger operating the operation unit with the fingerprint of the owner registered in advance, and issues a communication permission signal if the fingerprint does not match. It has security that cannot be used even if anyone other than the owner tries to use it for communication.
There is also security that cannot be used even if the wireless communication terminal is maliciously given to another person during communication.
