Biometric Authentication
Biometric authentication can deliver a very high degree of certainty about "who" an individual is at a level of convenience that is substantially better than a password. As organizations push for more secure passwords in response to increasingly sophisticated attacks, passwords are becoming even less convenient and more costly for organizations to administer and protect.
In order to deliver the promise of increased convenience, biometrics must be reliable and universal - meaning that a single touch is all it takes to authenticate every individual using the system. Unfortunately, conventional biometric technologies fall short of this goal, delivering single-touch true acceptance rates that may be no better than flipping a coin. Multispectral imaging is the breakthrough that enables Lumidigm to deliver single-touch true acceptance rates well in excess of 99%.
Conventional sensors perform a contact-based measurement: areas in contact are presumed to be fingerprint ridges and areas not in contact are fingerprint valleys. This technique is identical to ink and paper which has been used since the time fingerprint identification techniques were discovered more than a century ago. Under ideal conditions, conventional sensors may work well. Unfortunately, the performance of conventional sensors is severely degraded by non-ideal skin condition, poorly defined or damaged fingerprints, and environmental conditions such as dirt or moisture.
Multispectral imaging technology is a direct imaging approach where the object is illuminated under multiple illumination states and an image is collected for each of those states. In biometric authentication, these images are converted into a single two-dimensional fingerprint image and biometric matching is performed. Because multispectral techniques reconstruct the fingerprint from a combination of surface and subsurface information, they avoid all the failure modes associated with conventional fingerprint techniques and deliver superior performance under a broad range of real-world conditions.
Lumidigm's approach has been field-proven in large-scale, high-throughput applications around the world, from theme park entry to medication dispensing, from border crossings to ATMs. In addition, by combining our high-performance biometric authentication capability with barcodes, liveness detection, trusted devices, and biometric system design services, Lumidigm can deliver complete authentication solutions that are more cost-effective than offerings from conventional biometric sensor companies.
Looking Beneath the Surface
Multispectral imaging technology is the Lumidigm Advantage. Fingerprint readers with multispectral technology capture superior images quickly, on all people, in all environmental conditions.
Lumidigm is able to collect and process biometric images in a manner that makes fingerprint authentication and identification more robust, more inclusive and more reliable than other fingerprint sensors, which are vulnerable to a variety of conditions including the presence of topical contaminants, moisture, and bright ambient light. Simply stated, our sensors work where other technologies fail.
Lumidigm's innovation is multispectral imaging, a technology that enables the measurement of fingerprint characteristics that are at and beneath the surface of the skin. This enhanced data capture mitigates traditional system vulnerabilities and makes Lumidigm sensors the most secure and convenient solution for identity authentication.
Normal environmental and demographic real world conditions all represent significant challenges that have historically plagued the biometrics industry and have limited more widespread adoption. With multispectral imaging, these problems are solved. In major large-scale programs, pilot tests, field trials and evaluations, multispectral imaging from Lumidigm has proven to be the best technology in the biometrics industry.
Multispectral imaging also excels in liveness detection. Lumidigm technology is less susceptible to a wide range of well-known counterfeit attacks because its surface/subsurface capability can discriminate between real fingers and simulated fingerprint ridges. Multispectral imaging can quickly detect a fake by characterizing the subsurface data against the known characteristics of the human skin.
The ability to capture information from both the surface and subsurface of human skin forms the basis of Lumidigm's distinct competitive advantage. Lumidigm was formed when a noninvasive glucose monitoring technology seemed to suggest a new approach to biometrics. Today this same technology is being extended to capabilities beyond biometrics.
