Abstract

PURPOSE:To complete a security function by limiting the operators of a computer with use of a fingerprint discriminating switch. CONSTITUTION:A fingerprint discriminating switch 2 compares the fingerprint shown in a pushed switch with the fingerprint information stored previously and then outputs an On signal to a power unit 4 when the matching is obtained in the comparison. In other words, a fingerprint information input switch 5 outputs the signals to the unit 4 for supply the electric power to a fingerprint deciding device 7 and a fingerprint information storage 6 when the switch 5 is pushed by a finger. The switch 5 also outputs the fingerprint information of the person who pushed the switch 5 to the device 7. The device 7 compares the fingerprint information inputted via the switch 5 with that outputted from the storage 6 and then outputs an ON signal supplying the power to an operational processor 3 to the unit when matching is secured between both fingerprint information. Therefore the persons except those who are previously registered are unable to operate a computer 1.

BACKGROUND OF THE INVENTION With the advancement of information processing technology, computers are being used everywhere, and there has been a demand for enhanced security functions.

[0004] Conventionally, when restricting the number of people who can use a computer, this has been mainly accomplished by identification by inputting a password (ID) or by using a key switch.

[0005]

[Problems to be Solved by the Invention] In the case of password entry as described above, there is a possibility that the password may be forgotten or may be known to another person when the password is entered. Also, in the case of a key switch, if you forget the key,
There was a drawback that the computer device could not be used if it was lost.

The present invention was made in view of the above circumstances, and an object of the present invention is to provide an information processing device with enhanced security functions by limiting the number of people who can use the computer using a fingerprint discrimination switch. .

[0007]

[Structure of the invention]

[0008]

[Means for Solving the Problems] The information processing device of the present invention is an imaging device that instructs a power supply circuit to supply power by touching it with a finger, and also converts the fingerprint information into a video signal and supplies it to a fingerprint discrimination device. and a fingerprint discrimination device that compares the fingerprint information pre-stored in a storage device with the fingerprint information obtained via the switch equipped with an imaging device and permits use when they match. shall be.

[0009]

[Operation] As described above, the present invention is equipped with a switch that has the function of identifying fingerprints, and when the switch is pressed, the fingerprint is identified and information processing by the information processing device is permitted. This prevents anyone other than humans from using the information processing device. For this purpose, when the switch is pressed, the fingerprint is discriminated and if the fingerprint is registered, the power supply is turned on to each part constituting the information processing device by the power supply device.

[0010] This allows a specific password (ID
) It is possible to limit the number of people who use a computer device without using input or key switches, and it is possible to protect information that can be output by using a computer.

Embodiments Hereinafter, embodiments of the present invention will be explained in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention.

In the figure, reference numeral 1 denotes a computer device that performs information processing based on preprogrammed contents. Reference numeral 2 denotes a fingerprint discrimination switch (device), which compares the fingerprint pressed by the switch with pre-registered fingerprint information and outputs an ON signal to the power supply device if they match. Reference numeral 3 is an arithmetic processing unit. Reference numeral 4 denotes a power supply device, which supplies power to the computer device 1 including the fingerprint discrimination switch 2. Reference numeral 5 denotes a switch with an image sensor such as a CCD (hereinafter referred to as a fingerprint information input switch), which when pressed with a finger sends a signal to the power supply device 4 in order to supply power to the fingerprint discrimination device 7 and the fingerprint information storage device 6. Output against. Further, the fingerprint information of the person who pressed the fingerprint information input switch 5 is output to the fingerprint discrimination device 7. The detailed configuration of the fingerprint information input switch 5 is shown in FIG. Reference numeral 6 is a fingerprint information storage device in which fingerprint information of a person who can use the computer is stored in advance. Reference numeral 7 denotes a fingerprint discrimination device, which compares the fingerprint information input through the fingerprint information input switch 5 and the fingerprint information output from the fingerprint information storage device 6, and when they match, sends a calculation to the power supply device 4. It outputs an ON signal for supplying power to the processing device 3.

FIG. 2 is a block diagram showing the details of the internal configuration of the fingerprint information input switch. In the figure, reference numeral 51 denotes an image sensor, which is composed of a CCD or the like. Reference numeral 52 denotes a touch sensor, which uses a transparent material and detects when the finger is untied. The image sensor 51 is the touch sensor 5
This is an element that converts the fingerprint information of the finger that pressed 2 into an electrical signal. Reference numeral 53 is an LED, which waits for a function to illuminate the finger touching the touch sensor 52. Reference numeral 54 is a housing;
Reference numeral 55 is a substrate. Reference numeral 56 denotes a touch sensor driver, which generates an ON signal for causing the power supply device 4 to supply power to the fingerprint discrimination device 7 and the fingerprint information storage device 6 from a signal generated by the touch sensor 52. Reference numeral 57 denotes a fingerprint information processing device, which processes the video signal sent from the image sensor 51 into information that can be easily compared.

The operation of the embodiment of the present invention will be explained in detail below. First, when the user presses the fingerprint information input switch 5, a signal is output to the power supply device 4 to supply power to the fingerprint discrimination device 7 and the fingerprint information storage device 6. As a result, the power supply device 4 supplies necessary power to the fingerprint discrimination device 7 and the fingerprint information storage device 6. Then, the fingerprint identification device 7 compares the information of the fingerprint that pressed the fingerprint information input switch 5 with the fingerprint information stored in advance in the fingerprint information storage device 6, and if they match, the power supply device 4 is sent to the arithmetic processing device. ON to supply power to 3
Output a signal. Here, power is supplied from the power supply device 4 to the arithmetic processing device 3, thereby making the computer device usable.

[0015] Using FIG. 2, a detailed explanation will be given of how fingerprint information is taken in by the fingerprint information input switch 5. When you touch the touch sensor 52 with your finger, the touch sensor driver 5
