Finger recognition is riddled with issues the main one being over a dozen different medical conditions and various occupations where the user will be physically unable to use a contact fingertip reader.
There are many people who suffer from skin diseases. Some of these diseases have a strong influence on the process of fingerprint recognition. People with fingerprint diseases are unable to use fingerprint scanners, which is discriminating for them, since they are not allowed to use their fingerprints for the authentication purposes.
The various diseases include Hand eczema / hand dermatitis, Fingertip eczema / fingertip dermatitis, Pompholyx / dishidrosis, Tinea of the palm / tinea manus, Pyoderma, Pitted keratolysis, Keratolysis exfoliativa, Lichen planus, Acanthosis nigricans, Pyogenic granuloma, Systemic sclerosis, Raynaud’s phenomenon, Medication induced adverse skin reactions, Leprosy, Herpes simplex virus, Scabies, Erythema multiforme, Dermatitis artefacta, etc, so it a bigger problem than may first appear.
There is other fingertip verification technology from Veridian which does not rely on touching a fingertip reader but photos the fingers and palm and has a higher level of accuracy.
The technology is accepted by Interpol and the Dutch Government and in tests is more accurate than the fingerprint scanners built into phones.
It is not just scanning a part of a finger but more finger area.
It is also contactless technology that can be used by those with medical conditions preventing them contact fingerprint readers.
According to the manufacturers the benefits of 4 Fingers TouchlessID are:
• Extremely low False Rejection Rate of 1.0% at a 0.01% False Acceptance Rate
• Greater than 500 DPI resolution, the same as high-end flatbed fingerprint scanners
• Works under any lighting conditions because it uses the device’s LED flash
• Works on standard smartphones – no additional hardware required
• Liveness detection to prevent presentation attacks (spoofing)
• Uses a simple interface that makes it fast and easy to authenticate
• 4 Fingers provides high-quality prints for 1:1 or 1:n matching
• Supports legacy fingerprint database matching, including Interpol, NIST, and more coming soon.
Veridium Touchless ID is utilizing the powerful hardware that everyone has in their pocket as a device to acquire biometrics for secure and reliable authentication. Thanks to their proprietary algorithms, they are able to harvest the high-quality images using rear camera of most smartphone and use them to generate fingerprint images that have similar quality as traditional sensors, add to that their technology captures more area of the single finger than most of these sensors. And, their system is a multifinger system that uses the four fingers. Please check their website for more information.
Veridium Touchless ID has liveness measure to prevent use of photographs and their new Software Biometric Authentication Solution is Verified as Citrix Ready.
Dutch fintech bank bunq use this as their biometrics solution. With a higher level of accuracy than a traditional fingertip reader it also means a lower number of disgruntled customers swiping and swiping their finger trying to get it recognised.
