![]() ![]() Unlike other optical readers, SecuGen readers can operate under extreme temperature, humidity, rough and harsh environments and are highly resistant to abrasion and is nearly indestructible. SecuGen’s patented optical system was designed to produce the highest image quality in the most compact module available today making it easy to integrate into many kinds of devices. The longer focal lengths result in larger readers that cannot be reduced in size without compromising image quality. Conventional optical readers require longer focal lengths between lens and prism to reduce image distortion caused by the total internal reflection imaging method. SecuGen’s patented optical system and patented mass production quality control process have allowed us to produce high quality fingerprint readers that generate high image quality fingerprints without calibration issues.Ĭompact size. Such systems cannot endure high physical impact or shock, limiting their potential for outdoor or high traffic use. Because of this, image quality can vary significantly from one unit to another, and mass production of such units could be costly or nearly impossible. Some optical fingerprint readers require fine hand-calibration of its lens and optical components. Compared to SecuGen readers, conventional optical fingerprint readers use total internal reflection imaging methods that generate lower contrast images where it is not easy to distinguish ridges from valleys and can result in matching errors. SecuGen readers use a unique, patented SEIR (Surface Enhanced Irregular Reflection) imaging method to generate high quality fingerprint images that are characterized by (a) high contrast that makes it easy to distinguish the ridges from valleys, (b) low distortion that accurately represents the relative positions of the ridges and valleys across the entire image area, and (c) high resolution that clearly displays the minutiae in a fingerprint image. Static electricity can actually burn out an entire semiconductor-based system. SecuGen’s optical system is immune to electrostatic energy. No electrostatic problems: Semiconductor systems are inherently susceptible to damage from electrostatic energy, especially in carpeted areas. Unlike SecuGen’s optical system, semiconductor-based systems use fragile and expensive parts that are equally expensive to replace and maintain. Low maintenance costs: Semiconductor chip-based fingerprint recognition systems have higher maintenance costs than SecuGen’s system due to their fragility. Even then, they are far weaker than SecuGen’s optical-prism strength. Semiconductor-based systems must apply special surface treatments to protect their inherently weak surfaces. Physical strength is a key factor for versatile outdoor usage. Physical strength: SecuGen’s hardened optical glass-based system is physically stronger than semiconductor-based systems in terms of impact-resistance, scratch-resistance, weather-durability, and corrosion-resistance. ![]() If the template matches an enrolled template, the user is identified. SecuGen’s one-to-many (1:N) matching algorithm compares this template with all the templates enrolled in the database. A fingerprint is captured, and minutiae data is extracted from the fingerprint and converted into a template. If the templates match, the user’s identity is authenticated.įingerprint Matching for Identification: The enrolled user places the enrolled finger on the reader without stating his or her identity (for example, by not entering any user ID). SecuGen’s one-to-one (1:1) matching algorithm compares this template to the user’s enrolled template. ![]() A fingerprint image is captured, and minutiae data is extracted from the fingerprint and converted into a template. No actual image of the fingerprint is stored but is discarded after extraction.įingerprint Matching for Verification: The enrolled user states his or her identity (for example, by entering a user ID) and places the enrolled finger on the reader. This unique template is then encrypted for security and stored with other identifying information about the user. The reader captures fingerprint images and sends them to a computer for processing.įingerprint Extraction: SecuGen’s fingerprint template extraction algorithm (or “template generator”) analyzes and extracts minutiae points from the images and converts the minutiae data into a unique mathematical template, comparable to a 60 digit password. SecuGen provides both hardware and software components for these functions as well as additional features and tools.įingerprint Imaging: A user must first enroll his or her fingerprint and will be prompted to scan one or more fingers with the SecuGen fingerprint reader. Basic functions for a fingerprint biometric system include fingerprint imaging, extraction and matching.
