What is biometrics?

Biometrics comprises methods for uniquely recognising humans based upon either physical or behavioural characteristics. Physical characteristics are related to your body shape and include fingerprints, palm prints, face recognition, DNA recognition and iris or retina (parts of your eye) recognition. Your behaviour can be used in recognising voice patterns, gait or typing rhythm.

In a typical IT biometric system, a person registers with the system when one or more of the physiological characteristics are obtained, processed by a numerical algorithm, and entered into a database. Ideally, upon login, all of the features match 100%; then when someone else tries to log in, if he/she does not fully match, the system will not allow the log in.

Connective Touch products use fingerprint recognition as this is the least intrusive of the biometric characteristics to ‘read’. The sensor converts this reading into a digital code or algorithm. The software inside the device connects the mechanical lock to the sensor once a correct match has been identified. The device has the advantage of allowing you to move through a building without the need to carry keys or to remember numerical codes. For an organisation this eliminates the need to manage the issue of keys and key holders.

Interesting facts at your fingertips!

Circa 1000BC the Chinese were the first to use fingerprints on documents to make them legally binding. Every person in the world has unique finger prints. The chances of two people having identical prints are 1 in 64 billion. Fingerprints stay the same for life.

If you injure or cut any of your fingers and thumbs, your skin will grow back in the same pattern and as it heals your original print will return. Al Capone used acid on his finger tips to remove prints but was still identified 3 months later when the damaged skin healed itself. The Bertillon system to recognise individuals from their prints was first used in 1823.

Fingerprints on surfaces can be left either as patent or latent. Patent fingerprints are left when a substance (such as paint, oil or blood) is transferred from the finger to a surface and are easily photographed. Latent fingerprints occur when the natural secretions of the skin are deposited on a surface through fingertip contact, and are usually not readily visible. Forensic scientists can identify users of drugs from their fingerprints as the residues of the chemicals remain in the body. For example smokers, coffee drinkers and cannabis users can be spotted by this method. Some monkeys and apes also have unique fingerprints, just like us.

Connective touch fingerprint sensors

Our sensors contain tens of thousands of small capacitive plates, measuring extremely weak electrical charges that are created by the finger. Not optical measurement.

Why is this significant?

The finger is placed on the sensor and is scanned through wet & dry skin, as deep as 4 layers of live skin, via our High Sensitive Amplifier to match the stored template to live finger print. The template is retained and used to authorise access. An amplified capacitive measurement system allows protective coating 30-40 times thicker than other sensors, with a wear cycle tested to 1 million cycles! Security against Electro Static Discharge attack is up to 15kV.

Upon arrival at a device, the processor searches for distinctive patterns against the 3D template, allowing poor finger alignment. This can't be faked or fooled with copies of the fingerprint; it has to match the 3D template created by this specific technology.

Sensor used for the Connective Touch Flexi – overview information

It delivers superior 3D image quality with 256 gray scale values in every single programmable pixel. The reflective measurement method sends an electrical signal via the frame directly into the finger. This technique enables the use of an unbeatable hard and thick protective surface coating.

The sensor with its 3D pixel sensing technology can read virtually any finger; dry or wet. It can also recognise fingerprints if the user has a cut or small burn across the fingerprint.

Thanks to the new extremely hard and durable surface coating the sensor is protected against ESD well above 15 kV, as well as scratches, impact and everyday wear-and-tear. It has a designed micro-ergonomic guidance frame, simplifying proper fingerprint guidance and hence improving algorithm performance.



Here is what some of our clients who own the biometric units and systems said:
“I feel more independent know I don’t have to rely on staff like I used to if I lost my key”
“When I feel agitated I can get into my room quickly away from everyone into my
own space”
“ I know some people just can’t walk in”
“I feel more independent know I don’t have to rely on staff like I used to if I lost my key”
