Description

Description of utility model protection

1. Title:

Fingerprint switch

2.1 Technical area:
Electronic components

2.2 The state of the art known to the applicant:

Conventional switches, referred to in this context as security checks, such as those installed in car radios as so-called key cards, in PC systems as code locks, in cell phones as PIN numbers, in ATMs as PIN numbers and in electronic access systems, require the constant carrying or entry of certain PIN codes or electronic chip cards, which can be forgotten.

3. The problem underlying the utility model:

The access systems described in point 2.2 require either the memorization of a number, which may also be known to third parties, or the carrying of a chip card, which is very easily lost.

4. The utility model (the invention):

The fingerprint switch can be installed in a wide variety of devices, e.g. car radios, PC systems, cell phones, ATMs, electronic access systems, etc. It turns these devices into an insurmountable barrier for third parties and it is no longer necessary to learn any PIN numbers by heart, which may then be forgotten, or to carry any chip or key cards.

5. The commercial application of utility model protection:

The "fingerprint switch" utility model can be installed in all technical devices that require access protection.

6. Advantageous effect on the prior art cited in the application:

By installing the fingerprint switch, access protection for technical devices is simplified on the one hand, and on the other hand, a significantly higher level of security against manipulation is achieved compared to conventional access authorization systems.

7. A way to implement the claimed used design protection in detail

The fingerprint switch (item 01) can be installed in a wide variety of devices (e.g. car radios, PC systems, cell phones, ATMs and electronic access systems). It replaces, for example, electronic authorization chips or magnetic cards that authorize access to certain functions. The lens (item 02) mounted in front of the CCD chip (item 03) serves both as a fingerprint surface and to focus the fingerprint image for the CCD chip. The status LED (item 04) visualizes the switching state of the fingerprint switch. The integrated evaluation electronics (item 05) are cast in the housing of the fingerprint switch and the pin connections for soldering the switch (item 06) are used for programming, connecting the supply voltage and for signal transmission.

The fingerprint switch has all the functions for its programming already integrated; the fingerprint patterns that trigger the "authorization" function can be stored in the internal memory. The fingerprint images are compared using a fuzzy logic evaluation.

Claims (1)

Claim for protection Main protection claim The main protection claim for the utility model "fingerprint switch" for installation as a universal electronic component that can be installed in a wide variety of devices coming onto the market and can be used to put the devices into any switching state using this fingerprint switch. This switch can make conventional magnetic access cards, PIN numbers, secret numbers, access codes, or similar completely superfluous. Subclaim 1 Subclaim 1 relates to the evaluation electronics with memory built into the fingerprint switch, which makes it possible to store many different fingerprints and to grant all stored fingerprint patterns permission to switch the switch. Subclaim 2 Subclaim 2 relates to the installation of a fingerprint switch in a dual inline housing for soldering. Subclaim 3 Subclaim 3 for the utility model "fingerprint switch" relates to the fact that programming and supply pins are attached to the fingerprint switch, which enable it to be soldered onto circuit boards, whereby the supply voltage and a connection to a programming system can be created from the outside and signal inputs and outputs are led to the outside.
