Recently, the comprehensive inspection system of finger vein frontier inspection developed by Yantai border inspection station of Shandong Provincial Public Security Frontier command passed the professional demonstration and test successfully, marking a big step forward in the construction of "intelligent frontier inspection" of the border inspection station.

According to the introduction, the core technology of the inspection system is to obtain personal finger vein distribution map through finger vein recognition instrument, extract characteristic value from finger vein distribution map according to special comparison algorithm, acquire finger vein image through infrared CCD camera, store digital image of finger vein in computer system, and store characteristic value. In vein comparison, vein map is taken in real time to extract characteristic value. Advanced filtering, image binarization and thinning methods are used to extract features of digital image, which is compared with finger vein feature value stored in host computer. Complex matching algorithm is used to match finger vein features, so as to identify individuals and confirm their identities. The technology adopts advanced biometric technology, which has the characteristics of wide application, good anti-interference, high accuracy, non duplication, non forgery, security and convenience, and is a more advanced identification technology than fingerprint identification.




After the comprehensive inspection system of finger vein frontier inspection is put into use at Yantai port, the service object only needs to carry personal identity card and extract finger vein information when handling border inspection certificate for the first time, then "one finger in hand, the whole Hong Kong can walk", truly realize the goal of "remote and paperless" certificate processing, make the border inspection service more efficient and efficient, and effectively realize the "safety, security, safety and security" of border inspection "Comfortable and efficient".
