HAND IMAGE

Technology Palm Scan

Technology of recognition through the reading of the lines, wrinkles of the palm's skin which create a unique pattern and so identify the people without any error.

The Palm Scan's technology offers the following a dvantages compared to other biometric Technologies:

•  Insignificant ratio of false rejection (FRR: False Rejection Rate: when the system does not recognize a registered user). The Palmscan system receives biometric information from a body part (the hand's palm) which maintains constantly and without any changes parametered information. Unlike the fingerprint, the caracteristics of the palm can not be erased, dirty or damaged. Therefore, the level of “no-recognition” is below 0.2 % of the punches realized.

•  No false acceptancy: (FAR: False Acceptancy Rate: when the system mismatches with another user). The palm's skin has some caracteristics different for each person. Those caracteristics are due to the “erosion” of the embryo's skin during the pregnancy, so there is no genetic match. Information from the palm is between 30 or 100 times more important that information obtained from a fingerprint's scanner and is also more important than information from other biometric device: Iris, face…

•  The amount of information used for the biometric identification is very important when it's to avoid errors.

For example: recognize a city from a street (minimum information) or from a bridge, where the city can be divided in areas. The second option offers better probabilities for a correct recognition.

•  Contact Less technology: the palm is not in contact with the scanner: minimum maintenance and a maximum of hygiene = maximum reliability.

One of the worst difficulties of some of the biometric methods is the usury and amount of dirtiness in the biometric scanner that can generate false rejections and also false acceptations. In our case, the scanner can not be used-up because it is not directly in contact with users and does not need the maintenance that other biometric scanners do.

HAND'S VEINS

Palm Secure Technology

Technology developped by FUJITSU which captures the image of the hand's veins through the reflection of nearly-infrared rays emitted by the terminal. This makes it a system of authentification highly secure because it requires a blood circulation for his functioning.

The palm Secure technology has the following advantages compared to other biometric Technologies:

•  Insignificant ratio of false rejection (FRR: False Rejection Rate: when the system does not recognize a registered user).

Palm Secure reads the interior of the body (the hand's veins) to realize the biometric identification. So, the recognition will be realized aside from external changes of a person (dirtiness, injuries, increase of downy hairs, tattoos …)

•  No false acceptancy: (FAR: False Acceptancy Rate: when the system mismatches with another user).

Palm Secure is an extremely secure system, since the biometric data (the veins) can not be captured the same way as they can be with other biometric technologies (technique known as “spoofing”, which supplants the identity with the copy of biometric caracteristics, like the creation of false fingerprints, use of lenses…). Moreover, because the Palm Secure system only works with hands with blood circulation, cutting someone's hand will not allow the access.

•  Contact Less technology: the palm is not in contact with the scanner: minimum maintenance and a maximum of hygiene = maximum reliability.

One of the worst difficulties of some of the biometric methods is the usury and the amount of dirtiness in the biometric scanner that can generate false rejections and also false acceptations. In our case, the scanner can not be used-up because it is not directly in contact with other biometric scanners.

FINGERPRINT+CARD

Technology Smart Bio

Technology which combines finger print recognition with a “Smart Card” reader, which guarantees a complete privacy of the user's biometric data because the identification process of the fingerprint is realised without any need of stocking the fingerprint in a database.

The user's fingerprint is encrypted in the Smart Card that every user has. To use the biometric identification, the user introduces the card in the Terminal and puts its fingerprint in the scanner, producing an immediate identification in the terminal without keeping the fingerprint in any device apart from the Smart Card.

The protection of the information is complete because the cards Smart Card which keep the fingerprints – register 2 fingerprints each employee – it incorporates a high level of encrypting set up by the DES (Digital Encryption Standard) and MAC (Message Authentication Capability). So, in case of losing or having the card stolen, it would be impossible to use the card by another or application.

In addition to the advantage linked to the privacy of the biometric data, there are more advantages to emphasize:

- A verification (1:1) of the identity is realized: the fingerprint which is introduced in the scanner is the same as the one stocked in the card.

It means that the identification (in this case verification) will be faster than when the identification is from one to several (1:N) and will reduce the risk of FAR to 0.

- Scalability of the system: able the increase of the number of terminals and of the users per terminal without any limitation.

FINGERPRINT

As we highlighted before, compared to other Biometric Technologies, the fingerprint has some advantages and disadvantages:

Avantages to highlight :

•  Low price

•  Easy to use (the user needs to be familiar with this technology)

Disadvantages:

- High level of FRR (False Rejection Rate = 1% to 2%)

- Possibility of FAR (especially with techniques like “Spoofing”.)

- Need to be maintained (cleaning of the lense), and sensibility of the sensor

S.O.T. relies on the Fingerprint technology, currently the safest on the market, which mostly eliminates the disadvantages linked to the biometry through fingerprint.

Technology LE (Light Emitting) Sensor of Bio-I

The technology LE is the new technology which beats noticeably the technologies of fingerprint's reading which currently exist.

The sensor LE reacts when the fingerprint is in contact with the scanner emitting luminescence. The fingerprint being the only part in contact with the sensor and emitting light, its curbs form a diagram.

1. Unlike the optical reader, or “swipe”, the LE sensor, generates the exact image of the fingerprint, never mind the fingerprint being dirty or painted. In that way, it avoids the false rejections.

2. Includes the LFD technology (Life Finger Detection), which distinguishes the real fingerprint and its image. It's not possible to mislead the sensor using a graphic image of the fingerprint (because the fingerprint's curbs, which activate the sensor, are missing), or using inorganic materials (because these materials lack of conductivity which generates the luminescence needed).

3. Low level of FRR due to a highly developed algorithm to capture dried or moist Fingerprints.

4. Unlike the optical, swipe sensor or capacitive lectors (semiconductor), the LE sensor, is extremely resistant and does not require maintain or cleaning. The identification is not realised through the capture of an image and the sensor is immune from any effect (sweating, grated rind) which could mislead both fingerprint and sensor and can affect the identification and increase the FRR.

5. Consequence of the previous point is that the average life of the LE sensor is 1.5 millions of “users”. Unlike other technologies, the image is perfectly clear from the first use to the last one, 1.5 millions times later.
