Finger multi-mode character synchronous acquisition system

Abstract

The invention provides a finger multi-mode character synchronous acquisition system. The system includes a finger epidermal fingerprint acquisition module (1000), a finger OCT information acquisitionmodule (1100), a support module (1200), a finger OAG information processing module (1300) and a computer (1400). The support module (1200) is used to achieve data interface expansion so as to facilitate data transmission and power output between the computer and each module; the finger epidermal fingerprint acquisition module (1000) is used to achieve finger epidermal fingerprint information acquisition; the finger OCT information acquisition module (1100) is used to collect finger OCT information; the finger OAG information processing module (1300) is used to convert OCT information into OAGinformation; and the computer (1400) is used to further process the collected information. By using of the finger multi-mode character synchronous acquisition system, people can obtain the informationof finger epidermal fingerprints, finger dermal fingerprints and sweat glands and finger subcutaneous blood velocity.

Description

technical field [0001] The invention belongs to the technical field of biological feature identification, in particular to a system for synchronously collecting finger skin fingerprints, finger dermis fingerprints, sweat glands, and finger subcutaneous blood flow velocity information. Background technique [0002] The rapid development of information technology has made the whole society a combination of information and network. The security of social informatization and network has become an important issue. Traditional identity authentication methods are easy to be forged or impersonated, and biometric technology is to authenticate and identify the unique characteristics of individuals, which greatly enhances security. However, due to the limitations of single-modal finger biometrics in practical applications, such as being susceptible to data noise, and with the advancement of biometric forgery technology, anti-counterfeiting is more likely to be challenged.
