What is contactless fingerprinting and how does this affect our privacy?

With new advances in contactless fingerprinting, the technology once reserved only for the richest and most fictional settings is now more affordable, reliable, and accessible. With the need for security and avoidance of interaction, biometric security is needed. Fingerprint scanners are one form of futureproof biometric security that we rely on.

Contactless fingerprinting technology takes pictures of your fingerprints using the front-facing camera on your phone. This potentially reveals private body data. However, some worry about who could access the data collected by this technique. Via image processing, mobile devices can match fingerprints from several angles. Contactless fingerprinting technology captures people’s fingerprints by using the camera on a phone.

Current Status of Contactless fingerprinting

Contactless fingerprinting is taking off. In the NIST competition, 6 companies captured awards. A recent study found that contactless fingerprinting can match more traditional fingerprinting. The writers found that the best use of this new technology was a contactless capture device. The biometrics industry is rapidly growing, with contactless fingerprints being just one part of it. Biometrics is worth 127 billion dollars by 2030, according to some estimates.

Scenarios that Use Contactless Fingerprinting

The user physically touches their finger on the reader or scanner. A variety of security risks exist for those who work in or visit a building that requires touching to enter and exit areas. Touchless options provide a way to grant access to buildings without requiring physical contact. It’s difficult to find a balance with security requirements, but many people feel this is the best new solution.

These doors are vulnerable to infiltration because of the other methods like tailgating or piggybacking. Automatic doors in large buildings use a preset time delay to avoid closing too quickly, but this can make it easy for uninvited guests to come in and out.  The safety sensors are just strong enough to trigger the door to reopen if someone is detected by the passageway.

Privacy with Contactless fingerprinting

Despite the rise in biometrics, this feat is controversial. Shweta Mohandas, an Indian lawyer who specializes in privacy issues at the non-profit Center for Internet and Society, finds these can be especially concerning when these technologies are brought to developing economies where they don’t have standards or data protection laws.

Despite recent progress on contactless fingerprints, this research is not new. Companies are working on the technology, and fingerprinting has its benefits.

The process starts with an image processing algorithm that takes a photo of the fingertip and converts it into a machine-matchable fingerprint.

It’s best to take an individual’s fingerprints from a phone camera when the person is about five centimeters away from the camera. From there, the company’s algorithms detect and process your fingers. You need a resolution of at least two megapixels for their algorithm to work properly and be able to detect what defines your fingerprint, shadow, and light areas. The test results show that the technology is ready to be deployed in more places by law enforcement.

Contactless fingerprinting is a fast-growing industry, and it can help create security for some of your most intimate data. It uses your uniqueness to assure identification, with the use of different parts of your body which produce biometric data. Contactless fingerprinting technology is proving to be controversial, with the potential for fraud and identity theft. Some are pushing for a ban on biometric technologies in public places, claiming that it could “end anonymity”.

Learn the Advantages of Contactless Fingerprinting

Boon Edam UK is proud to introduce the first fingerprint scanner that can be used with a contactless payment, which allows for increased security. With the newest scan technology, MorphoWave Compact can automatically scan four fingers at once and create a 3D model in under a second.

The MorphoWave Compact operates with significantly less energy than other scanners and offers a more convenient user experience as well. Fingerprint technology has evolved rapidly over the years and will continue to develop with 3D imaging and deep learning. Although many hurdles have yet to be addressed, fingerprinting technology will continue to improve.

A fingerprint can distinguish the uniqueness of prints which has made it a popular form of identification. However, new scanning technology allows you to submit your fingerprint without compromising the accuracy of the image. With the emergence of contactless technology, fingerprint identification has become not only faster but more accurate. The usage of contactless fingerprinting is now prominent across all devices from credit cards to mobile phones. Contactless systems are the new and present standard in fingerprint identification

Touch-based methods distort and flatten fingerprints, rendering them useless. New technology has allowed for the development of contactless fingerprinting that still provides an accurate identification. This is especially useful in the fields of law enforcement, as well as commercial sectors looking for a more efficient way to identify individuals. Notwithstanding, the development of contactless technology is limited by issues that block further progress.

Recent Information

In 2011, biometric technology has rapidly made its way through commercial use to law enforcement.  This focus has been on the application of fingerprinting to law enforcement, showing that law enforcement faces key issues.

Scientists are trying to find a safer and more accurate method for scanning prints for greater reliability. With the ability to accurately compare fingerprints from older wet ink samples and new samples from contactless methods, advancements in fingerprint scanning can increase its use in law enforcement.

Researchers mention that newer fingerprint technology is effective but there are no statistics to compare accuracy and resolution. Fingerprint recognition algorithms, which are not standardized yet, are all different and often don’t work as well. The size of the files they create and how fast they process the information slows down the speed of your system and processing accuracy. The issues introduced by contactless fingerprinting are not unheard of in commercial applications.
