All biometric systems include the processing processes of acquisition, decoding, comparison and matching. Fingerprint identification technology is an early scientific application in the field of biometric identification technology. With the security technology of fingerprint identification gradually entering special institutions such as finance and government, more and more fingerprint identification applications appear in office buildings and enterprise civil fields, making fingerprint identification the most widely used at present Biometric technology with the largest market share.


Yinke intelligent, the manufacturer of face recognition intelligent lock, is an innovative international enterprise focusing on intelligent technology products and IOT platform. The company's business and products focus on "intelligent door lock, 5g mobile phone, intelligent hardware, mobile phone accessories and IOT system platform". Today, Yinke intelligence makes a brief comparative analysis of fingerprint recognition and palmprint recognition based on its own industry experience.

《1》 About fingerprint identification technology


Fingerprint identification technology is more and more widely used in today's society. Many third-party payment platforms and online banking software use this technology. Fingerprint identification technology is to confirm identity by identifying finger lines. Because all fingers do not have the same lines, there is basically no false recognition probability. However, whether fingerprint identification is applied to intelligent door locks or other intelligent hardware carriers, it still has its own defects, which are mainly reflected in the following aspects:


(1) . it has high requirements for the environment and is very sensitive to the humidity and cleanliness of fingers. Dirt, oil and water will not be recognized or affect the recognition results;


(2) , some people or groups have few or no fingerprint features, so it is difficult to image;


(3) . it is difficult to identify low-quality fingerprints such as peeling and scars, and the recognition rate is low. For some special groups such as manual workers with more calluses on their hands, it is difficult to register and identify them;


(4) Every time the fingerprint is used, the user's fingerprint marks will be left on the fingerprint collection head, and these fingerprint marks may be used to copy the fingerprint, which is also the biggest security risk and replicable.


(5) Someone warned that fingerprint technology may have fatal defects. At the cyber security conference in London, representatives representing major banks were told that the fingerprints of many elderly people had faded and could not be recognized by machines. Representatives of major banks were told at the London cyber security conference that many elderly people's fingerprints faded so badly that machines could not recognize them.


In fact, the application of fingerprint identification has brought many criticisms. For example, broken skin, incomplete fingerprint, dry and wet fingers have become research problems. Therefore, the crazy fingerprint set event is becoming more and more intense, and the market's cry for new technology is becoming stronger and stronger

《2》 About palmprint recognition technology


What is palmprint vein recognition technology? Palm geometry is based on the fact that almost everyone's hand shape is different, and the shape of the hand will not change significantly after people reach a certain age. When the user puts his hand on the hand reader, a three-dimensional image of a hand is captured. Next, the shape and length of fingers and finger joints are measured. According to the different data used to identify people, hand shape reading technology can be divided into the following three categories: the application of palm, the pattern of hand blood vessels, and the geometric analysis of fingers. Mapping the different features of the hand is quite simple and does not produce a large number of data sets.


In short, palmprint vein recognition technology is a new biometric recognition technology, which uses the vein distribution image in the finger for identity recognition. Its working principle is that the blood flowing in the finger can absorb light of a specific wavelength, and the clear image of palmar veins can be obtained by irradiating the finger with light of a specific wavelength. Using this inherent scientific feature, the obtained images are analyzed and processed to obtain the biological characteristics of palmar veins, and then the obtained palmar veins feature information is compared with the previously registered palmar veins feature to confirm the identity of the identified person.


The shape of palmprint vein is unique and stable, that is, the palmprint vein images of each person are different, and the vein images of different fingers of the same person are also different; The vein shape of healthy adults does not change, which provides a medical basis for palmprint veins.


Compared with fingerprint identification technology, palmprint veins are hidden inside the body, which is basically impossible to be copied and embezzled, and the security is very high. Moreover, the user has low psychological resistance and is less affected by physiological and environmental factors. It overcomes the factors such as dry finger skin, oil stain, dust, abnormal skin surface and so on. The whole process of the original palmprint vein image from capture to digital processing is less than 1 second, and can trigger many important characteristics, such as high accurate recognition rate (false recognition rate is 0.0001%, false rejection rate is 0.01%, registration failure rate is 0%), which makes it far better than fingerprint recognition technology in high security and convenience. At this stage, palmprint vein recognition still has undeniable competitive advantages.

Yinke intelligent, the manufacturer of face recognition intelligent lock, analyzes the comparison between fingerprint recognition and palmprint recognition! Conclusion:


In fact, the application of fingerprint identification has brought many criticisms. For example, broken skin, incomplete fingerprint, dry and wet fingers have become research problems. Therefore, the crazy fingerprint set event is becoming more and more intense, and the market's cry for new technology is becoming stronger and stronger


As a result, biometric living recognition technologies such as palmprint recognition, face recognition, iris recognition and voiceprint recognition are constantly emerging, which has brought countless innovative applications to the whole market and home. For example, face recognition intelligent lock, face recognition intelligent access control, face recognition attendance and door lock integrated face recognition intelligent door


In addition to face recognition, iris recognition also has good development potential in the future. Iris recognition is one of the most accurate biometric technologies at present. It has the characteristics of low error rate, difficult to forge, difficult to copy and difficult to damage biometrics. In theory, it will be more accurate and reliable than fingerprint recognition and face recognition. Based on the above characteristics, iris recognition technology will be the focus of future applications in security, national defense, e-commerce and other fields.
