MorphoSmart FINGER VP OEM Series- User's Guide Preamble

SSE-0000080207-03 March 2013


3. Preamble

We thank you for acquiring a MorphoSmart™ FINGER VP OEM Module. This biometric mul-timodal device is capable of capturing and processing at the same time fingerprint and fin-ger vein biometric data, thanks to the combination of Hitachi's finger vein imaging technol-ogy and Morpho’s fingerprint identification technology.

3.1 About fingerprint biometrics

Fingerprints are permanent and unique. They are formed before birth and last throughout one's life. Classification and systematic matching of fingerprints for different purposes have been in use since the late 19th century.

Figure 1 - Minutiae are classified in two categories: Ridge Ending and Bifurcation

Present on your fingers is skin, which is different from that on other areas of your body. This skin is rough or corrugated, consisting of raised portions that are called Ridges.

These ridges do not run continuously from one side to the other, rather they may curve, end, or divide into two or more ridges (Bifurcation and Endings). Barring accidental or in-tentional mutilation, the ridge arrangement is permanent.

Fingerprints can be divided into major ridge pattern type such as Whorls, Loops and Arch-es etc. Unique characteristics known as Minutiae identify those points of a fingerprint where the ridges become bifurcation or endings, as illustrated in Figure 1. These minutiae are the unique features, which form the basis of any system using fingerprint comparison techniques for identification and verification purposes.

Fingerprint is a mature biometrics, in use for various applications based on individual’s au-thentication or identification, as it offers an excellent trade-off between criteria such as user acceptance, easiness of use, performance, stability, cost effectiveness and interoper-ability.

SSE-0000080207-03 March 2013


Since the early eighties, Morpho has studied fingerprint characteristics and continually re-fined its expertise in fingerprint identification technology, developing first AFIS systems (Automated Fingerprint Identification Systems) and then applying its unique know-how and worldwide leading position to markets such as physical access control (premises), logi-cal access control (computers and networks), secure payment transactions and OEM ap-plications.

3.2 About finger vein biometrics

Vascular pattern recognition is a relatively recent activity in the field of biometrics. The reason is that only recently has one been able to observe the vascular pattern of a living human being in a convenient, non-invasive way. The first paper opening the way to this kind of observation was published in the early nineties.

Similarly to fingerprints, the formation of the vascular network is governed by many dif-ferent phenomena, competing to give the network its “final” shape. Therefore, it is widely accepted within the medical community that the vascular pattern is unique to each indi-vidual. Research suggests that the vascular pattern may be subject to changes in the course of the life of an individual but that it is a very slow process. Any significant change in this pattern indeed has dramatic consequences on all basic functions of an organism.

The specific traits of the vascular network, combined with recent advances in acquisition techniques, qualify it as an excellent candidate for biometric authentication and identifica-tion.

The basic principle for finger vein pattern acquisition is to select an illumination wave-length for which absorption from deoxidized hemoglobin (flowing freely in the blood stream) will be maximum and “background” absorption (all other cell tissues) will be min-imal. This way the vascular pattern will appear in great contrast “through” the different layers of skin in the finger.

The acquired image is then processed through standard image processing techniques to enhance the relevant signal and diminish noise, down to a smaller number of gray levels to be able to perform efficient matching.

Nowadays, vein recognition technology is among the most reliable and usable biometric technology available on the market. One of its strong assets is its resistance to forgery. Spoofing vein recognition is very difficult for two reasons : 1/ the actual information lies under the skin, is therefore impossible to acquire without the user’s consent, and 2/ the il-


SSE-0000080207-03 March 2013


lumination and imaging techniques require specific traits of blood vessels to form a bio-metrically valid image to be formed.

The technology implemented in the MorphoSmart™ FINGER VP devices is based upon pa-tented technology developed by Hitachi.

3.3 Multimodality and its advantages

Performances in terms of accuracy (characterized by the FRR @FAR ratio) remain one of the main challenges of the biometric industry.

But once a biometric technology has reached maturity, time and efforts in research re-quired to carry out improvements to the performances (e.g. by refining algorithms) are significant. For instance, NIST benchmarks about fingerprint recognition technology show that in the case of state of the art algorithms, it takes years to gain one point of accuracy.

Thus, various alternative approaches apart from the refinement of one isolated technolo-gy have been considered.

The first one consists in using several instances of the same biometric trait (e.g. the 10 fin-gers of one individual as in AFIS systems). This technique is known as multi-biometrics or multi-instances. It leads to improvements but acquisition phase and processing time are considerably increased, resulting in low cost efficiency (without mentioning the fact that universality is not guaranteed: for instance, not everyone presents 10 usable fingers).

Another way is to use several algorithms to process the same set of biometric data (multi-algorithms approach). This method is only efficient when applied to algorithms which do not show good performances by themselves and is also processing time consuming.

In the recent years, biometric industry turned to an innovative approach – Multimodality – which consists in combining one biometrics with another complementary one. The reason is that upstream studies showed that it could increase performances to a much larger ex-tent than any of the other approaches considered until then. It is particularly accom-plished when the two sets of biometric data are captured and processed at the same time, with one sole device.

Morpho has been a pioneer in this field, betting very early in the combination of finger-print and finger vein recognition technologies. Morpho indeed regarded these two tech-nologies as particularly adapted for an efficient fusion:

they are mature, stable and above all independent one from the other.

they can be captured together using one unique sensing device which do not necessi-tate any challenging technological evolution and thus preserves cost efficiency.

the same ergonomics of acquisition as the one of the fingerprint capture can be ap-plied, which has been widely and well adopted for its easiness of use.

After having enlisted the cooperation of Hitachi – for its perfect command of the finger vein imaging technology – Morpho developed the first ever multimodal finger vein and fingerprint device, now distributed on the market as the MorphoSmart™ FINGER VP OEM and DESKTOP Series.

The assets of the MorphoSmart™ FINGER VP are numerous:


SSE-0000080207-03 March 2013


it is capable to address those individuals who usually experiment difficulties to enroll on a mono-modal device (multimodal Failure To Enroll rate is close to the product of the two mono-modal FTE)

matching accuracy is increased, reducing the probability to reject genuine individuals and to accept impostors. Thanks to low False Reject Rates even for very demanding False Acceptance Rates (@ FAR=10-4, multimodal FRR is ten times lower than the one of the best modality), MorphoSmart™ FINGER VP is the common answer to comfort and security concerns in any biometric application.

resistance to spoofing is increased by combining the protection mechanisms intrinsic to each technology and also by making the most of the new characteristics resulting from the fusion.

We definitely believe that our MorphoSmart™ FINGER VP range of products will come up to the expectations of our faithful and most demanding partners, as the ultimate solution for Security, Accuracy and Performance!

MorphoSmart FINGER VP OEM Series- User's Guide Main principles

SSE-0000080207-03 March 2013


4. Main principles

4.1 Acquisition principles

4.1.1 Areas of interest

As regards fingerprint, the area containing the most relevant biometric data is usually lo-cated in the centre of the first phalanx.

As regards blood vessel pattern, the area of interest is usually located between the first and the third phalanxes.

Figure 3 - areas of interest

4.1.2 Ergonomics

Image acquisition is performed with CMOS camera. The optical imaging method depends on the kind of biometric data to be acquired. The fingerprint imaging process requires fin-ger's first phalanx (fingerprint area) to be in contact with the corresponding sensing area (square portion of the transparent surface). A finger tip guide (1) has been designed to help user to place the first phalanx of the chosen finger in the centre of the fingerprint im-aging area (2).


SSE-0000080207-03 March 2013


The vein pattern imaging process requires finger’s second phalanx not to be in contact with the device. A finger root guide (3) has been designed to hold finger into a flat position in order to avoid any contact inside the vein imaging active area.

It is highly recommended to wipe the device transparent surface with a dry cloth in case it is wet.

Figure 4 - Cross section of the acquisition area

4.1.3 Recommended fingers

Our devices have been designed for the use of fore, middle and ring fingers.

Among these, we advise people to use preferably the middle finger, which is usually the most suitable, or the fore finger as a second option. The ring finger indeed is not recom-mended for those who have short fingers.

Figure 5 – Recommended fingers


SSE-0000080207-03 March 2013


4.2 Enrollment process

The level of care taken during enrollment phase will impact all the next steps of the bio-metric recognition chain.

So it is absolutely necessary to teach individuals how to use properly the device according to the rules stated below, in order to acquire the best image quality. This will result at the end in the best quality of service.

It is important to notice that it is possible to enroll more than one finger: it provides an al-ternative for the ones who will have at a later stage their preferred finger hurt, cut, or even dirty.


SSE-0000080207-03 March 2013


4.2.1 Finger positioning rules


SSE-0000080207-03 March 2013


4.2.2 Finger condition

The following recommendations regarding finger condition will also help to get optimal quality at acquisition:

If wet, wipe finger

If dry or cold, warm up finger

If dirty, wash hands

Remove bandages or adhesive tapes from finger

Do not press or tense finger to avoid blood vessels constriction.

5.1.3.1.2 Method 2: screws fixed from above

Figure 8 – Module screwed, with screws fixed from above (example)

Whatever the fixing method, the elements useful for biometric data acquisition (transpar-ent surface, finger guides, lateral walls) must not obstructed by the end-product industrial design and surfaces.

5.1.3.2 Product inclination

As explained in section 4, the optimal quality at acquisition is obtained when user’s finger is flat, i.e. no inclination of the MorphoSmart™ FINGER VP device.

It is important to keep this recommendation in mind when integrating the module into an end-user product. In any case, device inclination shall not exceed 30°, in order not to dis-turb blood circulation.

5.1.3.3 Watertightness

In order to ensure watertightness between end-user product and module top surface, a gasket needs to be positioned within the yellow area shown below.

This gasket must be in compression.

In case the end-user product integrating the module targets an outdoor application, mod-ule shall be slightly tilted with an angle of 10° minimum in order to drain water from the sensing surface.

5.1.3.4 External light exposure

Optimal conditions of use are the following:

No direct sunlight.

No light sources with near IR radiations (incandescent lamps, halogen lamps, arc lamps…) within the cone described below.

Figure 10 – External light exposure

Replacing light sources, moving the device, or setting up a barrier* to disrupt the light are appropriate measures to conform to those optimal conditions.

(*) design of the barrier shall be adapted to the intensity of the light sources.

5.1.3.5 RF exposure

In case of integration into an end product embedding a RF emitter (typically an access con-trol terminal with contactless smartcard reader), radio emissions level measured on the external surface of the MorphoSmart™ FINGER VP OEM module shall remain below 800mV.

Note 2 - Serial cable

When using the SERIAL TTL interface, the cable between end-user application and

module has to be as short as possible, due to the low voltage signals used on this inter-

face. A length of less than 10 cm is recommended. The TTL logical table of the SERIAL

TTL link is the following:

Figure 13 – Serial TTL interface cable

The speed of the SERIAL TTL link can be set from 9600 bit/s to 920600 bit/s. (cf. § 7.3.5).

Once the speed of the link has been chosen, it is necessary to determine the value of the pull up resistor R depicted in the drawing above. The value of the resistor R shall be calculated in order to comply with the rising time.

Trising = (2*Baud Rate)-1 - 1.5µs

For instance at 115200bps, maximum Trising = 2.8µs.

SSE-0000080207-03 March 2013


6.2 Power supply

6.2.1 Voltage

The power requirements for a SERIAL TTL connected MorphoSmart™ FINGER VP OEM de-vice are in the range of 3.9 V to 5.3 V.

The power requirements for a USB connected MorphoSmart™ FINGER VP OEM device must comply with USB specifications (5 V).

Voltage drop in the cable should be monitored to avoid a too low voltage on the connect-or of the MorphoSmart™ FINGER VP OEM device.

6.2.2 Power consumption

In order to optimize power consumption, the MorphoSmart™ FINGER VP OEM devices support three operating modes:

Full operating, sensor on: a biometric command has been issued by the Host system and a finger is expected to be placed on the sensor.

Idle mode: no command in progress, the device is waiting for a command from the Host system.

Standby mode: the activation of this low power mode is described in the section be-low.

Operating mode

Power consumption

USB SERIAL TTL 5.3 V

SERIAL TTL 3.9 V

Standby mode < 10 mA < 10 mA < 10 mA

Idle mode 185 mA 160 mA 195 mA

Full operating, sensor on 435 mA 400 mA 550 mA

All values are typical.

6.2.3 Standby mode

This mode is automatically activated when the “suspend” USB command is received from the Host system. This command shall be issued by the USB driver of the Host system.

For example, when a Windows Host system enters the suspend mode or the hibernate mode, a USB “suspend” command is sent to every connected USB devices.

The MorphoSmart™ FINGER VP device exits automatically standby mode when required by the relevant USB command.

SSE-0000080207-03 March 2013


7.2 Main recommendations

7.2.1 Start-up of the MorphoSmart™ FINGER VP device

After power up, the start-up time is typically 2 seconds.

During this period if the Host system sends any command, it will be ignored. If after the normal start-up time the MorphoSmart™ FINGER VP doesn’t return any response, it is rec-ommended to send back the command after a 100 - 200 ms delay.

7.2.2 Cold restart of the MorphoSmart™ FINGER VP device

A cold restart is performed by a “power off – wait a bit – power on” cycle on the MorphoSmart™ FINGER VP device. It is highly recommended to ensure that the Host sys-tem (hardware and software) is able to perform this action.

When the Host system is no more able to communicate with the MorphoSmart™ FINGER VP device (no answer seems to be returned from the device), it is recommended to per-form a cold restart on the MorphoSmart™ FINGER VP device.

If the MorphoSmart™ FINGER VP device is blocked for any reason, the cold restart will un-block it.

If the connection channel is still unavailable, a hot (software restart) or a cold restart (hardware restart) should be performed on the Host system.

7.2.3 How to check if the MorphoSmart™ FINGER VP device really started

After a cold start, the Host system may need to check if the MorphoSmart™ FINGER VP is available.

This can be done by sending one of the “read only” commands, such as GET_DESCRIPTOR or GET BASE CONFIG. When the MorphoSmart™ FINGER VP device is started, an answer will be returned to the Host.


SSE-0000080207-03 March 2013


7.3 Main ILV commands

To manage MorphoSmart™ FINGER VP devices, Host shall use the so-called ILV (Identifier Length Value) protocol over USB or SERIAL TTL physical link.

For an exhaustive description of the implementation of this protocol, please refer to the MorphoSmart™ Host System Interface specification.

7.3.1 Initialization functions

GET_DESCRIPTOR: Retrieves basic information from biometric module.

7.3.2 Biometric functions with capture

VERIFY: capture multimodal finger template, and compare it to one or several refer-ence templates.

ENROLL: capture one or several multimodal finger template, and conditionally:

create a record with these templates, in the local database

return the fingerprint image(s) to the Host system

return the multimodal finger template(s) to the Host system

IDENTIFY: capture a multimodal finger template, and compare it to all the templates stored in the local database.

CANCEL: enables to cancel a biometric command in progress.

7.3.3 Main database management functions

CREATE BASE: create a local database (and define its structure)

ERASE BASE: erase the content (records) of the local database

DESTROY BASE: delete the content and the structure of the local database

ADD RECORD: add a record to the local database

REMOVE RECORD: remove a record from the local database

7.3.4 Search database management functions

FIND USER BASE: search for record which has a specified data in a specified field

UPDATE PUBLIC DATA: update the content of a database public field

UPDATE PRIVATE DATA: update the content of a database private (and public) field

GET PUBLIC FIELDS: get the content of a database public field of all records

GET DATA: get the content of a database public field, for a specified record

GET BASE CONFIG: get database configuration (structure and current number of rec-ords)

7.3.5 Configuration functions

GET_MSO_CONFIG: Retrieve the value of one configuration parameter

MODIFY_MSO_CONFIG: Modify the value of one configuration parameter

CONFIG UART: Change SERIAL TTL port configuration

8. Biometric characteristics

8.1 Matching threshold value

This parameter can be set to values from 0 to 10. This parameter specifies how tight the matching threshold is. Morpho recommends threshold 5, but according to customer’s ap-plication requirements, this threshold can be adjusted in order to have a more secure con-trol (higher threshold, less false acceptances) or a more comfortable control (lower thresh-old, less false rejections).

We remind that the better the FAR is, the worse the FRR is, and vice versa. FRR varies from one kind of population to another.

0 Low threshold for test purposes only.

Low FRR, high FAR

1 FAR < 1 %

2 FAR < 0.5 %

3 FAR < 0.1%

4 FAR < 0.05 %

5 Recommended value.

FAR < 0.01 %.

6 FAR < 0.001 %

7 FAR < 0.0001 %

8 FAR < 0.00001 %

9 FAR < 0.0000001 %

10 High threshold for test purposes only.

High FRR, Low FAR.

8.2 Security level

This parameter can be set to STANDARD, MEDIUM or HIGH.

STANDARD Security Level is default value.

Use MEDIUM or HIGH Security Level to increase the protection against fraud (but it may affect the FRR and response time).

8.3 Database filling time

The table below gives typical duration of database filling with 2 multimodal finger tem-plates, when redundant template check is off (please refer to the description of ID_No_Check_On_Template optional ILV in ‘MorphoSmart™ Host System Interface Speci-fication’ documentation, by default this option is on).

Number of records USB SERIAL TTL at 115200 Bauds

500 5 s 150 s

5000 50 s 15 min

8.4 Verify performances

The verify process compares the search multimodal finger template to one or more refer-ence templates in less than 2 seconds (typical time).

Hit No Hit

1 s 1.8 s

Notes:

The measure starts with finger valid placement on the sensor and stops with result returned to the Host system.

No extra time when matching involves one search template and two references.

Misplaced finger will increase the matching process time and could affect the matching result (refer to section 4).

8.5 Identify performances

The identify process compares the search multimodal finger template to all the records of the database.

Number of records Hit No Hit

500 1 s 1.8 s

5000 1.5 s 2.2 s

Note:

The measure starts with finger valid placement on the sensor and stops with result returned to the Host system.
