Embodiment Construction

[0026] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. While the present invention has been shown and described in terms of exemplary embodiments, it will be obvious to those skilled in the art that various modifications can be made without departing from the spirit and scope of the invention. It should be noted that although the same structural elements are shown in different drawings, the same structural elements are denoted by the same numerals. Also, in the description of the present invention, if it is judged that a known function or construction may unnecessarily obscure the essence of the present invention, a detailed description thereof will be omitted.

[0027] In the following description, when an expression of "comprising" certain structural elements appears in a certain position, it means that the position does not exclude another structural element, and may also include other structural ...

Abstract

The invention provides a finger-vein-based authentication system. A finger vein of a user can be identified, compared and distinguished at a low power and a high speed by analyzing a level set curvature. Therefore, the invention provides a finger-vein-based authentication system comprising a light source unit, a filter unit, a CCD camera unit, a storage unit, and a control unit. The light source unit is configured to emit near-infrared light; the filter unit is configured to only allow light that is emitted by the light source unit and has a specific wavelength to pass; the CCD camera unit is configured to capture an image including a finger of a user and convert the captured image into an electric signal; the storage unit is configured to store a level set curvature program, wherein the level set curvature program executes the operation of extracting a finger vein pattern from the image including the finger by using the level set curvature; and the control unit is configured to drive the level set curvature program.

Description

technical field [0001] The present invention relates to finger vein authentication, and more specifically, to finger vein authentication that identifies, compares, and differentiates a user's finger veins at a lower power / faster speed by a method of analyzing level set curvature. Background technique [0002] In general, biometric authentication is the use of human physiological or behavioral characteristics to identify individuals. Representatives of biometric authentication technologies include fingerprint recognition, face recognition, iris recognition, finger vein recognition, signature recognition, speaker recognition, and so on. Among the above-mentioned biometric authentication methods, fingerprint recognition and finger vein recognition have advantages because the recognition performance is superior, the user does not resist and feel no discomfort, and the recognition time is short. [0003] The concept that a user's fingerprint can be used for identification has lo...
