- How Fingerprint Scanners Work.
- Introduction to How Fingerprint Scanners Work.
- Fingerprint Basics.
- A fingerprint scanner system has two basic jobs -- it needs to get an image of your finger, and it needs to determine whether the pattern of ridges and valleys in this image matches the pattern of ridges and valleys in pre-scanned images. ...
- The scanning process starts when you place your finger on a glass plate, and a CCD camera takes a picture. ...
- If the darkness level is adequate, the scanner system goes on to check the image definition (how sharp the fingerprint scan is). ... If the fingerprint image has good definition, a line running perpendicular to the ridges will be made up of alternating sections of very dark pixels and very light pixels. ...
- If the processor finds that the image is crisp and properly exposed, it proceeds to comparing the captured fingerprint with fingerprints on file. ...

- "Welcome to the Dungeon", fingerprint technician Ken Shaw greeted me as I entered Boston's sector four crime lab. ...
- Additionally, a few objects from recent crimes sat in different areas at different stages of processing, including an elaborate but broken picture frame that once held a picture of Benjamin Franklin, and a simple but functional sawed-off shotgun that had been involved in at least one homicide. ...
- It is this pattern of ridges that is called the fingerprint. When the fingertip comes in contact with something, a layer of sweat containing amino acids in the shape of the fingerprint will be left on the object. ...
- Super glue (all brand names are virtually identical chemically) has an affinity for these amino acids, and as such super glue gas will naturally cluster and solidify around them, leaving a sticky image of the fingerprint. ...

- A "who you are" system is actually looking for physical evidence that you are who you say you are -- a specific fingerprint, voice or iris pattern. ...
- "Who you are" systems like fingerprint scanners have a number of advantages over other systems. ...
- You can't guess a fingerprint pattern like you can guess a password. ...
- Optical scanners can't always distinguish between a picture of a finger and the finger itself, and capacitive scanners can sometimes be fooled by a mold of a person's finger. ...

- However, the greatest hope seems to be lying in the possibility of the fingertip structure recognition (this structure is reflected in the fingerprint pattern). ...
- They show ''live'' fingerprint images directly from a finger without the need for ink and paper which have been traditionally used by policemen since Galton times 4 , 5 . ... The description of a typical optical fingerprint imaging system is given in 6 .
- Such a device would not have any moving parts and could replace today's keyboards, mice, graphic pads, and fingerprint identification systems, though this is not the end of its potential applications. To complete the picture, it is worth knowing that it is feasible to create a device which would be small, inexpensive (a kind of a chip), and could really fit in a button. ...
- The Picture of the actual existing camera.
- It is however worth mentioning that the algorithms which have been developed allow not only fingerprint recognition but also significant compression of the fingerprint data. ...
- A fingerprint is hardly noticeable because the signal level it gives is at least 30 dB lower than the the signal given by a real finger (in contrast to this, for optical devices this level does not change significantly). The above observation is also true when soot or metal powder is used in order to enhance the fingerprint. ...

- www.fhcrc.org
- Why care about our genetic fingerprint?.
- The readout from this information is often described as a genetic fingerprint a glimpse at how our DNA differences make each of us unique.
- But simply having a readout of our genetic variation won't give a complete picture of who we are, Kruglyak says. ...
- To complicate the picture even further, scientists already know that most human characteristics, diseases and behavior are likely to be traceable to the combined effects of multiple genes, making it harder yet for researchers to identify simple causes and cures.
- It's not inconceivable that someday an annual physical exam will find you and your doctor poring over your genetic fingerprint, surveying your potential disease risks and selecting treatments and prevention strategies tailored to your genes.

- www.brighthand.com
- The first picture (see photo, left) is of one of the new h5400 Series iPAQs that includes both Bluetooth and 802. 11b, as well as a biometric fingerprint reader (more about that later). You'll also notice that you can clearly see a microphone to the left of the fingerprint reader. ...
- As you can see in the picture to the right, there's a removeable door (removed in the picture) on the back of the iPAQ 5400 that doubles as a flat lithium-ion battery. ...
- Still, the most ground-breaking new addition is the thermal swipe technology used in its fingerprint reader. HP now allows you to secure your device in a variety of ways, from a password to a PIN to a fingerprint, or any combination of the three. To use a fingerprint, you must first "enroll" your fingerprint by training the iPAQ to recognize it.

- Will I need a new picture? .
- Do I have to submit my fingerprint each time I use one of the new biometric card readers? .
- The implementation of biometric technology (in this case fingerprint recognition) requires the use of a different type of badge to gain access to the SIDA. ...
- Both the transmission and storage of fingerprint data will be encrypted. ...
- In most cases capturing the fingerprint enrollment, verifying personal information and exchanging badges will take ten minutes or less. ...
- Will I need a new picture?.
- No, unless your appearance has changed significantly since the last picture.
- Do I have to submit my fingerprint each time I use one of the new biometric card readers?.
- At this time, the Port plans to activate the fingerprint feature at only the outer perimeter to a restricted area. Card readers downstream will have the fingerprint feature disabled, but could be activated at the Port's discretion. It will be clear to users when a fingerprint is not required.
- Unfortunately, the two systems are not compatible so a new fingerprint enrollment is mandatory.
- But since the new badges require a fingerprint to be imbedded inside before it can be printed, we have to process them one by one.

41. Security Access Using Biometric Fingerprint Technology
- www.biometritech.com
- Security Access Using Biometric Fingerprint Technology.
- My initial thoughts about using a fingerprint or hand geometry solution for security access were filtered by my experiences in law enforcement -- ink-rolled prints that were time consuming and messy. Recently, my observations of optical fingerprint systems for positive identification still required rolling all 10 fingers until the print passed the systemsâ ™ test for acceptability for use in the FBIâ ™s Positive Identification system. ...
- The result of this requirement could provide a national fingerprint database of airport, airline, and contract employees. ...
- AN OVERVIEW OF FINGERPRINT TECHNOLOGIES.
- Optical Fingerprint Scanners. ... The process, referred to as Frustrated Total Internal Reflection, a form of spectroscopy, essentially takes a picture of the finger. It also takes a picture of the dirt, greases, and contamination found on the finger. ...
- Digital Fingerprint Scanners. ...
- Capacitance Fingerprint Scanners. ...
- Thermal Fingerprint Scanners. This technology uses infrared to sense the temperature differences between the ridges and valleys of the finger to create a fingerprint image. ...
- Ultrasonic Fingerprint Scanner. ... Ultrasound can penetrate through many mediums, and thus can image through the contamination that is found on the finger or that builds up on the fingerprint platen to get a consistently high-quality image of the finger each and every time. The improved image quality results in accuracy rates approximately a factor of 10 (an order of magnitude) better than any other fingerprint system on the market today. The images are completely compatible with existing fingerprint databases, should cross matching to existing databases be an application requirement. ...
42. Fingerprint Recognition Through Circular Sampling
- www.cis.rit.edu
- Fingerprint Recognition Through Circular Sampling.
- Since 1924, the FBI has accumulated about 30 million sets of fingerprints2 making the matching of a single fingerprint with such a collection very difficult. With the advent of advanced computer technology in the past few decades, automated fingerprint identification systems (AFIS) can effectively perform what would otherwise be a laborious and time consuming task. This study presents a method to fingerprint recognition by way of a spatial re-sampling of the pattern through concentric circles. ...
- 1 Fingerprint Uniqueness .
- What actually makes a fingerprint unique depends on one main factor. ... Although the manner in which the ridges flow is distinctive, other characteristics of the fingerprint called ‘minutiae’ are what is most unique to the individual (See figure 1 for several minutiae representations). ...
- Three major fingerprint classifiers .
- The fingerprint identification system must account for each of these factors. ... For instance, the scaling of the fingerprint is often considered as someone may be identified even though their fingerprints were recorded at a very young age. ...
- Digitized fingerprint images are obtained either through a dedicated fingerprint scanner or the standard scanning of inked fingerprint impressions. ... Specifically, all the minutiae in the fingerprint must be extracted and mapped. The fingerprint is also categorized so that it only has to be matched with its class. ...
- An image, such as that of a fingerprint, may be considered as a two-dimensional continuous signal. ...
- These cells are commonly called picture elements or pixels. ...
- Prior to testing the present matching process on fingerprint images, a series of test images were created to observe for any perculiarities in the algorithms. ...
43. International Biometric Group
- www.biometricgroup.com
- So what kinds of biometrics will we see in wide use by mid-decade? The most likely options are fingerprint, hand, iris or facial recognition. Fingerprint recognition is by far the most developed technology, with various competing methods for scanning your digit, some of which even work through latex gloves for medical or industrial applications. Fingerprint biometrics are already used to check welfare eligibility in California, Texas and New York, and some governments—the Philippines, Argentina, Hong Kong—are creating national ID programs with the technology. And dozens of Fortune 500 companies already use fingerprint scans for network or PC access. ...
- Oldest, because when someone compares the picture on your driver’s license with your face, that’s human-powered biometrics. ... Facial scanning, while expensive and new, has one big attraction for some agencies: almost everyone is already “enrolled”—that is, thanks to drivers licenses and passports, almost everyone has a picture on file somewhere that can be scanned into a recognition system. ...
- ” In one case, for example, a fingerprint scanner was fooled by a finger made of Gummi bears. ...

- The programme combines fingerprint and digital picture in passports. Fingerprint remains as a unique feature because it cannot be duplicated by any means, said Dr Abdul Awal, a faculty member of computer science, who supervised the project. ...
- In the process, passport officials will record fingerprint of thumb and take a digital picture of the passport seeker.
- "All we need is a computer, a fingerprint detector and a digital camera along with the software," he said.
- Developed countries that have already introduced MRPs do not have the unique feature of fingerprint in them. So, there are chances to forge them by changing picture and data, which are usually embedded in barcodes.
- Awal said the new passports will have picture printed digitally and there will be no scope to change it.
- Airports and land immigration posts will require fingerprint detectors so that track could be maintained during departure and arrival from abroad.

- To hide the image of, say, a fingerprint in a picture, the print and the picture are scanned into a computer. The computer runs an algorithm that converts the fingerprint into a series of numbers. These numbers are then used to shift the position of some of the dots that make up the picture (see graphic). ...
- The system can conceal several different images in the picture at once by shifting the dots of the different colours separately. ...
- Rosen's team has so far shown that six different icons can be embedded in a colour picture. To reveal the hidden fingerprint, you have to scan the picture again. The computer then uses the same algorithm that encoded the fingerprint to decipher it. By measuring the displacements of the dots in the picture, the computer reconstructs the fingerprint.
- A suspect's picture could then be unscrambled to reveal the hidden fingerprint. If the fingerprint is missing, or does not match the suspect's, security will know something fishy is going on.
47. eBCVG Network Security - Your source for information security

- The most obvious of these systems are, like you have all seen 'm in movies; the fingerprint- or iris-scan systems. ... The fingerprint system used to make an inkt-copy of the top of your finger, where your fingerprint is, and after that, law-enforcement could always compare your fingerprint with the image of it, that they had taken on an earlier date. ... Nowadays law-enforcement doesnt use ink anymore; they make a high resolution picture of your fingerprint. And this is where the fingerprint system differs from the finger-scan system. Finger-scan technology also uses the fingerprint but only uses small amounts of specific information from it. The amount of bytes used to save a finger-scan is about 250 up to a thousand bytes, whereas an exact copy of the fingerprint uses 250 kilobytes. So in fingerprinting an exact copy is made, but with a fingerscan there's no exact copy saved and thus there can not be an actual reconstruction of the fingerprint from the saved information. ... Not only this, but also other recognisable things like freckles, rings and other specific chracteristics are encoded into a 512 byte Iriscode which is the iris-scan's equivalent of the fingerprint. ... One can not give his retina to another user, or his fingerprint. Another can not steal one's retina or fingerprint like he could his password or keycard. ... ) Other advantages of a biometric authentication system are the fact that a user can not loose or forget his retina, his fingerprint or his voice.

- Dystrophy, Map-dot-fingerprint.
- Background: Corneal map-dot-fingerprint dystrophy is by far the most common corneal dystrophy and is named from the appearance of its characteristic slit lamp findings. Map-dot-fingerprint dystrophy also is known as epithelial basement membrane dystrophy, and Cogan microcystic epithelial dystrophy. ...
- Map-dot-fingerprint dystrophy has been found in several families with a presumed autosomal dominant pattern, but in most cases it is not familial. ...
- Corneal abnormalities associated with map-dot-fingerprint dystrophy are the result of a faulty basement membrane, which is thickened, multilaminar, and misdirected into the epithelium. ...
- Blebs, a less common manifestation of map-dot-fingerprint dystrophy, are localized areas of fibrillogranular material or thickened basement membrane.
- In the US: Estimates of the prevalence of map-dot-fingerprint dystrophy range from 2-43% of the general population. Of patients with map-dot-fingerprint dystrophy, 10-33% have recurrent corneal erosions. As many as 50% of patients with recurrent corneal erosions have map-dot-fingerprint dystrophy. ...
- Mortality/Morbidity: Patients with map-dot-fingerprint dystrophy may be asymptomatic. ...
- Radial keratotomy (can have corneal epithelial opacities clinically indistinguishable from map-dot-fingerprint dystrophy).
- Diamond burr superficial keratectomy is very useful for recurrent erosions associated with map-dot-fingerprint dystrophy that does not respond to keratectomy with a Kimura spatula. ...
- Excimer laser phototherapeutic keratectomy is an excellent treatment for recurrent corneal erosions associated with map-dot-fingerprint dystrophy, with results similar to above superficial keratectomy procedures (but much more expensive in most settings).
- This procedure is not as successful for recurrent erosions associated with map-dot-fingerprint dystrophy, which is usually more diffuse and often migratory.
- Map-dot-fingerprint dystrophy findings may fluctuate but tend not to progress over time. ...
- While patients with map-dot-fingerprint dystrophy may be bothered by painful recurrent erosion episodes and/or decreased vision, they typically are most frustrated by the unpredictability of the condition. ...
