Recently, the fingerprint identification technology has a brand-new scanning method, which is different from the previous judgment based on arts and sciences. This time, by monitoring the pore secretions, the accuracy of the judgment is greatly improved in combination with the previous fingerprint science and technology.
With the successful development of this technology, criminals now want to escape the task that is almost impossible to accomplish; human sweat pores will produce unique polymers due to sweat discharge, and when the relevant test substances come into contact with these polymers, they will produce different reflect. With this technology and the previous fingerprint recognition technology, only a small part of the fingerprint is needed to confirm the identity information. Sensor technology has played an extremely important role in this new fingerprint analysis and clinical diagnosis of pores.
Actually, the idea of ​​using sweat pores in conjunction with fingerprint confirmation information has also appeared before, but it has been abandoned due to the long time, poor reliability, and high price. This time, this new technology was invented by a research team led by chemical engineer Jong-Man of Hanyang University in Korea. First, a simple discoloration polymer deposit is used for ink jet printing. When the fingertips are pressed, the polymer comes into contact with the sweat and the color changes from blue to red, which makes it possible to form a unique fingerprint.
Traditional fingerprint identification information requires a large area of ​​fingerprint information to be collected, and it is easy to cause errors in the process of collection and comparison. In contrast, this new technology requires only a small fraction of fingerprints to identify identity information and ensure accuracy. The same new fingerprint identification method can also be used for clinical diagnosis of sweat blockage.
