from Russia

Certifications
Proprietary Technology of Smeared Image Compensation
Technology for Scanning Dry and Moist Fingers
Application Software

PAPILLON has been engaged in designing and manufacturing optical scanners since 1992. More than 3500 PAPILLON scanners are successfully running throughout the Russian Federation and abroad.

The family of PAPILLON’s fingerprint scanners being produced presents models for imaging all types of impressions: rolled and touch fingerprints, slaps (impressions of all 4 fingers of each hand taken simultaneously and of the thumbs), palmprints and writer’s edges.

Sensing platens of our scanners are of size ample for imaging full, not truncated, impressions even of king-size hands.

Since 1997, those models of PAPILLON scanners that gain greater demand in the biometric market have been certified to meet the requirements of the ANSI/NIST, FBI and Russian national standards.

1997: PAPILLON DS-7 livescan fingerprint and palmprint device is FBI-certified.
2003: PAPILLON DS-14 (FS-7) livescan fingerprint and palmprint device is FBI-certified.
2006: PAPILLON DS-14 is tested at the Forensic Science Center (FSC) of the Ministry of the Interior (MOI) of Russia under The Program and Procedures for Testing the System of Electronic Fingerprinting to Meet the Fingerprint Image Quality Requirements in Law-Enforcement Agencies of Russia. In view of the results of testing, PAPILLON DS-14 has been recommended to internal affairs bodies in Russia as a livescan capture device to create forensic quality tenprint cards.

The DS-7 and the DS-14 (they were about 220 and 140 pieces manufactured respectively) have proved their operability and they are still in use in Russia and at some law enforcement agencies of other countries.

In 2007, the mentioned models were taken out of production having been replaced by a next-generation palmprint scanner PAPILLON DS-40.

2007: Certification of PAPILLON DS-40 fingerprint and palmprint scanner and PAPILLON DS-31, DS-30 and DS-22 capable of taking rolls.

2010: Certification and startup of batch production of a brand-new palmprint scanners PAPILLON DS-45 аnd DS-45M notable for their enlarged sensing platen and minimized overall dimensions.

2011:  Certification of PAPILLON DS-30N and DS-30NM fingerprint scanners.

Improved versions of PAPILLON fingerprint certified scanners DS-30 and DS-22, new DS-30N, DS-30NM and DS-22N are ready for sale.

Successfully competing with known manufacturers, PAPILLON’s scanners have won several tenders for the supply of equipment for state-concerned agencies in Russia and some foreign countries.

PAPILLON’s fingerprint scanners feature a program method for compensating smears that appear when capturing rolled fingerprints. Resultant images of impressions are generated through program splicing of fragments sequentially captured.

The electronic imaging process that PAPILLON designed uses a single fixed optics with a high-resolution digital camera.

Unlike the hardware-based method that implies an increase in frame frequency in order to compensate for smears, the program method uses cameras providing reasonable frequency, i.e. 8-10 frames per second.

Thus, PAPILLON’s developers succeeded in finding an ingenious compromise solution that ensures that:

• the rolled impressions are imaged at high resolution and with clear detail, almost completely devoid of smear effects
• the scanners have an affordable price due to refusing to use expensive high-resolution and high-speed cameras
• nonuse of moving mechanical parts and other automation facilities enhances the product reliability in service

PAPILLON employs a combination of both the hardware- and the software-based solutions to nullify the effect of dry and worn-out skin on the imaging process.

The program approach consists in lowering the sensitivity threshold of the optical system. It is the scanning operator who makes a decision to change the value of the said parameter.

The sensitivity threshold can be lowered as for a single scanning session so as for series of recordings.

This method noticeably increases the image comprehension for dry and worn-out fingers due to slight abatement of the noise filtering capability.

The hardware-based method has been realized through the use of an ad hoc polymeric coating of the scanner platen (membrane). Physical-mechanical properties of such coating ensure better contact with objects being scanned, even for fingers with deficient natural moistening.

To eliminate the impact of any moisture that is present on the platen or on fingers, PAPILLON uses a new imaging technology – moisture discriminating optics – that is able to distinguish between fingerprint ridges and furrows full of liquid (grease, moisture or sweat).

PAPILLON’s livescan fingerprint and palmprint devices are generally included into stationary or mobile systems for electronic fingerprinting, called PAPILLON LIVE SCANNER, and for express identity checks, viz. PAPILLON FILTER Express ID Check.
