Abstract

Aiming at the fingerprint identification and security problem, here we provide a new fingerprint identification hardware system design. There is a circle of touch area around the fingerprint module which contain 3 layers. The first layer is a kind of high molecular material of water absorbing and quickly dry. The second layer is pressure sensor layer. The third layer is circuit layer which transforms the pressure signal to electronic signal.

When there is perspiration that has affect on fingerprint identification, users can click some points of the touch area, or slide in the touch area with a specific trajectory. The touch area will absorb the perspiration on user's finger and the combination of the click points or the specific trajectory will be the entry password before fingerprint identification.

Fingerprint authentication enhancement through quick drying material pressure induction module

As the smart phones are becoming more popular, a lot of users complain that when their fingers have water, oil, sweat or dust, they couldn't quickly unlock their smart phones by fingerprints especially in urgent situation. Then they wonder whether there is a better method to quicklyclean up the fingers and unlock the phones. At the same time, many smart phones users keep complaining about the security for fingerprint, such as when users are deep in sleep or falling into coma, somebody can easily use their fingerprint to unlock their smart phone and steal the personal information. Combining the both requirements above, smart phone users are urgent to request one method to enhance fingerprint security combining with quick drying material pressure induction module.

Aiming at the fingerprint identification and security problem listed in the background above, here we provide a new fingerprint identification hardware system design. There is a circle of touch area around the fingerprint module which contain 3 layers. The first layer is a kind of highmolecular material of water absorbing and quick dry, the second layer is pressure sensor layer´╝îthe third layer is circuit layer which transform the pressure signal to electronic signal.

When there is perspiration that has affect on fingerprint identification, users can click some points of the touch area, or slide in the touch area with a specific trajectory. The touch area will absorb the perspiration on user's finger and the combination of the click points or the specific trajectory will be the entry password before fingerprint identification.

This is a new fingerprint identification hardware system design which is the assist and enhancement of current fingerprint identification hardware on smart device.

There is a circle of touch area around the traditional fingerprint module which contain 3 layers as shown in the picture below:

The first layer Layer1 is a kind of high molecular material of water absorbing and quickly dry. The material is used to absorb the perspiration and other liquid or besmirch which may affect the identification of fingerprint.

The second layer Layer2 is pressure sensor layer. The touch area will be divided into some points whose acreage need to match the size of user's finger. The pressure sensor can be placed as some points or as a line or curve between two points on the area. Users can put their finger there which will be used for fingerprint identification...
