A Report on Palm Vein Technology Engineering Essay
The seminar report uploaded here discusses the workings of Palm Vein Recognition technology. Palm vein scanning systems, such as those for finger vein identification, use a technology based on the use of near-infrared rays and the way hemoglobin in the veins responds to them. The hemoglobin in the blood is supplied with oxygen in the lungs and arteries. Palm vein recognition has received significant attention regarding its use in biometric identification. The features of the palmar vein provide a superior level of personal safety and reliability. The contactless palm authentication technology consists of image detection and software technology. The palmar vein sensor Fig.2 captures an infrared image of the user's palm. The illumination of the infrared beam is controlled according to the illumination around the sensor, and the sensor can capture the palm image. TECHNOLOGY: Palm vein authentication technology consists of a small palm vein scanner that is easy and natural to use, fast and highly accurate. The palm of the hand is held a few centimeters above the scanner and reads the unique vein pattern within a second. A vein photo is taken and the palm pattern is recorded. This may serve as a guide for future research into the development of a low-cost, effective vein finder for medical application and possible commercialization. In addition, this technology will provide opportunities for collaborative studies between physicians and medical technology professionals. The unique vein pattern remains the same throughout a person's life. The vein pattern in the palm is also larger than the fingerprint or iris, allowing the scan to contain more data to increase identification accuracy. More privacy protection. Palm vein patterns cannot be scanned from a distance. The palm of your hand should be in front of the sensor. Advantages: • The veins in the palm are wider in size and the blood vein patterns are complex in structure, this makes it unique for each person and therefore offers more security during authentication. • Skin properties independent. •Is a contactless technology. The first step in using this technology is to keep the palm parallel. Thus, palmar vein images are gray-level images in which dark gray to black veins appear on the gray background. 1. Extraction of vein features. A major problem in using palm veins as a biometric modality for person recognition is the extraction of palm vein features from NIR images and finding efficient descriptors for palm vein appearance..
