Safe and efficient, non-contact "hand brushing" identification helps epidemic prevention and control

2022 year , The volatility of the epidemic , Let many cities in China press the pause button again . Non contact identity authentication , Because it can reduce the transmission path of the virus , It has become an important demand for the normalization of epidemic prevention in various regions . The present , Non contact biometric technology is developing rapidly , According to the research organization Mordor Intelligence A report released predicts , Affected by the new crown epidemic , To 2026 year , The global non-contact biometric technology market will be close to 238.5 Billion dollars , The compound annual growth rate is 16.17%.

In the track of non-contact biometrics , Murky technology “ Brush hand recognition ” Is a new player . It uses palm print 、 Palm vein information for biometrics , Just open your hand to murky's “ Brush your hands ” equipment , In the blink of an eye , You can complete identity authentication , Safe and efficient .

“ hand ” Biometric collection on the needs to be informed by the user , And the palmar vein is hidden under the skin , Forgery threshold is high , Natural with living characteristics , Can better protect privacy , Personal information is more secure . At a time when epidemic prevention and control and privacy protection are increasingly valued , Non contact of murky technology ” Brush hand recognition “ Technology is also more and more widely used .

“ Brush your hands ” distinguish · Principle analysis

Murky technology “ Brush hand recognition ” Palmar vein recognition with palmprint , The process is similar to the general biometric technology , Including image acquisition 、 Image preprocessing 、 Feature extraction and matching . among , In terms of image acquisition , Palmprint recognition Just like general biometrics , What is used is Visible light imaging . and Palmar vein Recognition is different , What is used is Reflective imaging , Through the difference of absorption rate of near-infrared light between deoxyhemoglobin in vein and other physiological tissues , An image of the formation of the palmar vein . say concretely , When doing image acquisition of palmar vein , Will use specific wavelengths of near-infrared light to illuminate the Sagittarius , Light passes through the epidermis , Enter subcutaneous tissue and scatter in it . The near-infrared light in the scattering process is largely absorbed by deoxyhemoglobin in venous blood , Therefore, when imaging, the image sensor , The vein veins appear dark shadows where they are , Other areas that are not veins show higher brightness . After a series of digital processing , Finally, a black-and-white vascular pattern image that is conducive to feature extraction is formed .

Palmprint and palmar vein on one hand , There are about hundreds of their own characteristics , And murky technology has built a multi-scale representation , From pixel to overall image , Murky made a comparison of the middle scale label （label） and vector （vector） And so on , The feature information is greatly expanded . Based on this , Murky then uses the original vector search algorithm , Realized palmprint 、 High precision comparison of palmar vein features , Make every authentication and identification secure 、 accurate .

“ Brush your hands ” distinguish · There are many benefits

Non contact is conducive to epidemic prevention and control COVID-19 is still raging. , And use murky's “ Brush your hands ” Identification and identity verification , No need to touch the equipment , You don't need to take off your mask , It reduces the possibility of cross infection . Palm vein information is not easy to forge Murky “ Brush your hands ” Identify the Palmar vein Hidden under the skin , Characteristic information is difficult to forge , And it needs flowing blood to make the equipment recognize , With in vivo detection function , Make identification more secure . Active identification , privacy protection “ Brush your hands ” Identification requires active authorization . Input information from the palm , To identity verification , Users need to reach out actively , Willing to authorize their biometric information to complete identity authentication , There are very few cases of passive acquisition or passive identification . The scene is rich , Convenient operation and maintenance The hand brushing device can be integrated with the system software of the device owner , Used in various scenarios requiring identification . Take the smart Park as an example ： Hand brushing equipment can be used in office areas Access control 、 Punch in , In the parking lot 、 The station can realize manual parking 、 By bus , You can brush your hands in the apartment 、 Go out and register wait . such , Even in an open park , It can also realize the high efficiency of personnel flow 、 Digital management , The park can not only reduce costs and increase efficiency , More convenient for users 、 quick 、 Secure authentication experience .

“ Brush hand recognition ”· future “ near ” stay “ palm “ in

“ Brush your hands ” Such a safe and efficient way of identification , It's not far from us . In recent years, , Big foreign factories began to pay attention to “ Brush your hands ” technology , Related products have gradually come into people's attention . for example , Amazon has started to use it in its own retail stores and whole foods supermarkets Amazon One, Realized “ Brush your hands ” Settle accounts .
