Very well. SecuGen's optical prism is specially designed to resist distortions caused by dirt, oil or moisture buildup. Unlike many other optical devices, there are no expensive coatings to disturb on the hard surface of the prism. Designed for high usage and daily exposure to touch and contaminants from hands, SecuGen's rugged and scratch-resistant fingerprint sensor can easily be cleaned or wiped with a cloth or household glass cleaner if necessary.

Physical strength. SecuGen's optics-based system is physically stronger than semiconductor-based systems in terms of impact-resistance, scratch-resistance, weather-durability, and corrosion-resistance. Physical strength is a key factor for versatile outdoor usage. Semiconductor-based systems must apply special surface treatments to protect their inherently weak surfaces. Even then, they are far weaker than SecuGen's optical-prism strength.

Low maintenance costs. Semiconductor chip-based fingerprint recognition systems have higher maintenance costs than SecuGen's system due to their fragility. Unlike SecuGen's optical system, semiconductor-based systems use fragile and expensive parts that are equally expensive to replace and maintain.

No electrostatic problems. Semiconductor systems are inherently susceptible to damage from electrostatic energy, especially in carpeted areas. SecuGen's optical system is immune to electrostatic energy. Static electricity can actually burn out an entire semiconductor-based system.

High image quality. Traditional fingerprint devices require fine hand-calibration of its optical components. As such, image quality can vary significantly from one unit to another depending on the level of calibration. Accordingly, mass production of such units is costly or nearly impossible. Furthermore, such systems cannot endure high physical impact or shock, limiting their potential for outdoor use. SecuGen's patented-pending optical system allows mass production of high quality image capturing modules with minimal calibration requirements. Additionally, conventional optical fingerprint recognition systems use FTIR (Frustrated Total Internal Reflection) image processing methodology. In such systems, high image quality requires longer focal lengths and therefore longer and larger modules. To make these conventional optical systems smaller, image quality must be compromised and the system is left to work with inherently distorted images. Image distortion effectively lowers accuracy and reliability. By contrast, SecuGen's Fingerprint Recognition System utilizes a unique, patented SEIR (Surface Enhanced Irregular Reflection) imaging method. Using this breakthrough technology, SecuGen's fingerprint modules are able to achieve distortion-free image capturing while drastically reducing its physical size.

Compact size. In traditional optical systems, higher image quality means longer focal lengths, which in turn means larger devices. SecuGen's patented-pending optical system provides distortion-free high image quality in the most compact module-design available today.

Resistant to grease and oil buildup Image quality is reduced when grease or oil builds up on the optical surface. Unlike other optical systems, SecuGen's patent-pending optical prism does not allow for grease or oil to build up on its surface. In addition, SecuGen's patented- pending optical prism is highly resistant to abrasions and is nearly indestructible.

Performs well under extreme conditions. Unlike other optical systems, SecuGen's fingerprint recognition system can operate under extreme temperature and humidity. Due to its superior wear-resistance, SecuGen's optical system functions well even under the most difficult outdoor weather conditions.

Low Cost. SecuGen offers the most cost-effective fingerprint recognition solution with the highest image quality available in the market today. SecuGen's advanced automated manufacturing processes mean reliable mass production. The result is a tremendous value to our customers at a significantly reduced cost.

The verification speed is generally less than half a second.

First, it is helpful to explain the meaning of these rates, what affects them, and how they are determined.

The False Rejection Rate (FRR, also called False Non-Match Rate or FNMR) states the percentage of instances that an authorized individual is falsely rejected by the system. The False Acceptance Rate (FAR, also called False Match Rate or FMR) states the percentage of instances that a non-authorized individual is falsely accepted by the system. FRR and FAR (or FNMR and FMR) are diametrically opposed. Therefore, raising the FAR will lower the FRR and vice-versa. Accordingly, FRRs and FARs can be adjusted to fit the requirements of the entire security system. SecuGen software products offer nine different security levels that allow you to adjust the FRRs and FARs to reach desired results.

In a real-world system, there are many factors that can affect FRR and FAR. For a minutiae-based fingerprint recognition system, these factors include: (A) the fingerprint capture device, (B) the fingerprint minutiae (template) extraction algorithm, (C) the fingerprint minutiae matching algorithm, (D) the user interface and (E) the user. There may be myriad other factors that can depend on the system, how it is used and the conditions in which it is used. For this reason, many tests for "performance," "accuracy" or other test that determine FRR and FAR must be able to control as many known factors as possible and maintain them consistently throughout all tests.

Independent of factors A, D, E and other variables, SecuGen's Pro algorithms have been extensively tested by the National Institute of Standards and Technology (NIST) in one of the industry's most reliable, rigorous and statistically significant tests of performance and interoperability of core fingerprint algorithms (MINEX).

Specifically, SecuGen's Pro extraction ("template generator") and matching ("matcher") algorithms that are supplied in SecuGen's SDK Pro series in the SDK Collection were tested and identified as compliant for template encoders and matchers for the United States Government's Personal Identity Verification (PIV) program.

Unlike other optical systems, SecuGen's SEIR (Surface Enhanced Irregular Reflection) optical technology combined with SecuGen's proprietary algorithm is able to capture extremely high quality, accurate, and distortion-free images. SecuGen's optical system is thereby able to capture even the driest fingerprint images that other optical systems can not.

When a three-dimensional fingerprint is applied to the sensor window of a SecuGen fingerprint recognition device, the fingerprint is scanned and a gray scale fingerprint image is captured. All fingerprints contain a number of unique physical characteristics called minutiae, which includes certain visible aspects of fingerprints such as ridges, ridge endings, and bifurcations (forks in ridges). Minutiae are generally found in the core points of fingerprints; core points are located near the centers of fingerprints. Figure 1 shows the positions of core points within fingerprints. The user is enrolled, or registered, in the database after a special minutiae-based algorithm extracts key minutiae points from the three-dimensional image at the time of acquisition (see Fig. 2).

password, a PIN) - but who you are. Biometric security systems can be used in two distinct ways: (a) to verify a user's stated identity, or (b) to identify a user by finding the closest match in a database of stored fingerprint templates. The two methods are known as verification and identification, respectively.

The process of "authentication" refers to the validation of users on any system. Systems that use fingerprint biometrics include access control, time & attendance, and computer networks among many others. Fingerprint recognition systems are used to authenticate people, and are ideal for supplementing or replacing simpler, less secure authentication methods such as passwords or IDs. Most experts agree that fingerprint recognition is the best of the various biometric techniques for its proven reliability, convenience, and cost-effectiveness.

The quality of your fingerprint image is relative to the number of minutiae points captured. If the number and locations of the minutiae remain consistent whenever your fingerprint image is scanned and captured, your fingerprint image will successfully match the template of your registered finger. Fingerprint images that do not contain adequate minutiae data are not acceptable as personal credentials, and are therefore invalid. Figure 3 shows poor-quality fingerprints, characterized by smudged, faded, or otherwise distorted areas on the fingerprint. Conditions like these may be attributable to a number of factors, including excessively dry or wet skin, or scarring.

Fig. 3 Examples of poor fingerprint images

SecuGen's fingerprint matching algorithm is capable of extracting the correct minutiae even without benefit of a perfect print. However, the positioning of your finger and the relative wetness or dryness of your fingerprint when it is placed on the optic window for scanning are both important factors in getting a match. Bright lighting and humidity may also contribute to lowered performance if you are not careful. To minimize the chances of rejection by the system, especially in high security environments, you should know how to properly position your finger on the fingerprint reader. The best advice is to cover the optic sensor window completely with your finger to ensure that the maximum fingerprint surface area is exposed to the scan. A common mistake is to touch the sensor with the tip of your finger, which contains little or no usable minutiae.

When the temperature is low, or just after washing hands, the fingerprint is often dry. In this case, you may moisturize the fingerprint by breathing on it, or by touching your forehead to pick up surface oil before applying it to the sensor window.

In order to capture the most minutiae, maximize the surface area of the fingerprint on the fingerprint input window by covering the sensor completely. It is okay for your fingertip to extend beyond the length of the sensor to center your fingerprint. Apply pressure lightly and evenly without moving it during the capturing process. Figure 4 shows the correct positioning of the fingerprint on the input window. Figure 5 shows the most common mistakes made during the initial phase of enrollment.

Fig. 4 Correct placement

Fig. 5 Common mistakes

During enrollment, or registration, the process requires you to lift your finger from the device then put it back for a second capture. This second placement is needed because the registered fingerprint template is made from two samples. The method by which the system will ask you to do this varies depending on the kind of a device you're using. For instance, a PC peripheral device might make the request via a dialog window on your PC monitor, while a stand-alone unit for access control might display instructions to users on an LCD panel. Although the user interface may vary between applications, basic usage will be the same for any installation using SecuGen fingerprint readers.

For optimal speed in matching and verification, SecuGen's fingerprint system algorithm is set to allow up to ±45° for input fingerprint rotation, as illustrated in Figure 6.

Fig. 6 The maximum angle of finger rotation

Apply pressure lightly and evenly during the capturing process. You only need to apply as much pressure as is required to hold a piece of paper between your fingers. Pressing too hard may result in an overly dark or blurred image. On the other hand, if too little pressure is applied, the resulting image may be too faint, similar to the dry fingerprint. A little practice is all that is needed for users to get the feel of it.

As a preventative measure, it is best to enroll more than one finger so that if one finger becomes unavailable for authentication, you will have an alternate finger to use. For this reason, many biometric products, including SecuGen software, provide the option of multiple finger enrollments.

If your biometric product features a password or PIN back-up, you can use this feature in case no finger or properly working fingerprint device is available.

If none of the above options work, please contact your IT administrator or technical support provider for help. For SecuGen software support, you may contact our Technical Support Team.
