Four-joint-finger acquisition technology-based VTM

Abstract

The invention discloses a four-joint-finger acquisition technology-based VTM (Virtual Teller Machine). The VTM comprises a four-joint-finger acquisition apparatus used for acquiring a feature value of four joint fingers and sending the feature value to a database, the database used for storing a feature value of a specific user and comparing the input feature value with a pre-stored feature value, and a main controller used for controlling the four-joint-finger acquisition apparatus to acquire the feature value and obtaining a comparison result from the database. The VTM has the advantages that a scanning array is generated by utilizing a brightness difference of scanning reflection rays; the scanning array comprises necessary coordinate values and element values, and then the feature value is extracted from the screened element values; and in the whole process, the feature extraction of the four joint fingers can be finished according to a simple algorithm without forming picture information, and the left and right hands can be distinguished.

Description

technical field [0001] The invention relates to a financial terminal, in particular to a VTM machine based on the quadruple-finger acquisition technology. Background technique [0002] Since the advent of smart financial terminals such as VTM (Virtual Teller Machine) and STM (Smart Teller Machine), they are increasingly replacing traditional ATMs because they can save a lot of manpower and improve customer experience. Smart terminals can provide functions that cannot be realized by traditional ATMs, such as account opening, account cancellation, transfer, and business communication. However, these functions require strict identity verification for users, unlike ATMs that use cards as a means of authority confirmation. Smart financial terminals use multiple biometric methods such as fingerprints, fingerprints, fingerprints, and voiceprints for user identity confirmation and authorization confirmation. Among them, fingerprint identification is an authorized identification wit...

AI Technical Summary

Problems solved by technology

Among them, fingerprint identification is an authorized identification with high authority, so the technical requirements for fingerprint identification are very high, while the VTM machine in the prior art can only identify a single fingerprint, and the efficiency is very low

Finger recognition in other fields is based on image processing. Image processing requires high-definition and high-precision image acquisition devices, resulting in high cost of the whole machine, and the efficiency of image processing is much lower than that of other digital processing.
