JPH0197776A - Fingerprint and voiceprint type release method - Google Patents

Abstract

PURPOSE: To enhance controllability and safety by digitizing a signal of a fingerprint, voiceprint or the like for input to a checking process part, checking data previously stored in a storage element against the input signal, and permitting unlocking if they are coincident. CONSTITUTION: A signal sensed by a sensing element 1 for fingerprints, voiceprints or the like is digitized by a digital converter 2 and input to an input processing part 3. Fingerprints, voiceprints or the like are previously digitized and stored in a storage element 4 which uses a magnetic disc. When this method is used for the locking part of, e.g. a door, pressing of a thumb against the fingerprint sensing element 1 allows the sensing element 1 to sense its fingerprint as an image signal, which is in turn digitized. The processing part 3 checks the data stored in the element 4 against the input signal, and if they are coincident, an unlock signal is transmitted to the locking part 5. Therefore, operations are simplified and safety can be enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a method of unlocking a locked part using a fingerprint or voiceprint.

Conventional technology Traditionally, locks installed on the entrance doors of houses, automobile doors, etc. were locked and unlocked by inserting the chest into the 45 holes of the lock. Do you control the trowel section? Meanwhile, devices have also been developed that unlock the lock by inputting a signal using a magnetic card or PIN number.

Problems to be solved by the invention However, when unlocking with Hikoji,
There is a high risk of the sword being lost or stolen, and it takes time and effort to insert the hook into the lock and unlock it at night. Furthermore, the magnetic card type also has drawbacks such as the risk of it being stolen or lost by others, and the PIN number type having many risks of forgetting the number or having it deciphered by others.

In order to solve these problems, the present invention inputs the fingerprints, voiceprints, etc. of each individual as digital signals to the verification processing section, compares them with the fingerprints and voiceprints stored in advance on a magnetic disk, and performs verification when they match. A method in which an unlocking signal is transmitted from a processing unit to a locking unit to unlock the lock, and the method is characterized in that the safety of the locking unit can be improved without requiring any effort in the unlocking operation. It is.

A foolproof way to solve problems Hereinafter, the configuration of the present invention will be explained with reference to the drawings.

The signals sensed by the sensing element 1, such as voiceprints and fingerprints, are converted into digital signals by the digital conversion circuit 2, and inputted to the verification processing section 3, where the data stored in advance in the storage element 4 for voiceprints and fingerprints and the input signal are combined. When the input signal and the stored data match in the verification processing section 3, the verification processing section 3 transmits an unlocking signal to the locking section 5 to unlock the lock. Note that 6 in the figure indicates a reset button.

Effects of the Invention As shown in the block diagram of FIG. 1, the present invention stores fingerprints and voiceprints of each individual in a fingerprint and voiceprint storage element 4 using a magnetic disk.
It converts the voiceprint into a digital signal and stores it. When used for a locking part of an entrance door, a car door, etc., when the door is closed, a reset button 6 connected to the verification processing part 3 is operated to transmit a locking signal to the locking part 5 to keep the door locked. It is something. A fingerprint/voiceprint sensing element 1 is installed on the side of the locking part 5, and for example, a COD solid-state image sensor or an image scanner is used as the fingerprint sensing element. Therefore, when unlocking the locking unit 5, the fingerprint of the thumb is detected as an image signal by pressing the thumb against the fingerprint sensing element 1, and this is converted into a digital signal by the digital conversion circuit 2 for verification. When the input signal matches the data inputted to the processing section 3 and stored in the fingerprint storage element 4, an unlocking signal is transmitted to the locking section 5 to unlock the locking section. Even when using voiceprints,
A microphone and a voiceprint analysis circuit are used as the sensing element 1, each person's voice is input to the microphone, and the voiceprint signal is converted into a digital signal by the digital conversion circuit 2 and inputted, and the voiceprint storage element 4
The lock is unlocked only when the data stored in the lock matches the input signal.

Therefore, it is possible to easily unlock the front door of a house or a car door with your fingertips or with your voice, and since fingerprints and voiceprints are unique to each person, it is impossible for a hermit to forge them. The above-mentioned remarkable effects can be achieved, such as improving the safety of the parts.

[Brief explanation of the drawing]

FIG. 1 is a block diagram showing an unlocking method according to the present invention.

Claims (1)

[Claims] 1. Converts the signal detected by the sensing element such as a fingerprint or voiceprint into a digital signal and inputs it to the verification processing unit, which compares the input signal with data stored in advance in the storage element such as the fingerprint or voiceprint and converts it into an input signal. A fingerprint/voiceprint type unlocking method is characterized in that when the data and stored data match, a verification processing unit transmits an unlocking signal to a locking unit to unlock the door.
