Embodiment Construction

[0031] Hereinafter, the present invention will be described in detail by illustrating various exemplary embodiments of the invention with reference to the accompanying drawings. However, inventive concepts may be embodied in many different forms and should not be construed as limited to the illustrative embodiments set forth herein. Furthermore, the same reference numerals may be used in the drawings to denote similar elements.

[0032] First, please refer to figure 1 , which shows a schematic diagram of an iris image acquisition device according to an embodiment of the present invention. The iris image acquisition device 100 is used to acquire and protect an iris image, so as to prevent malicious persons from stealing images with iris characteristics during wired (such as USB or MIPI interface) or wireless transmission, thereby improving the security of iris recognition.

[0033] like figure 1 As shown, the iris image acquisition device 100 includes an image sensor 110 , a...

Abstract

The invention provides an iris image obtaining apparatus and method, and an iris image identification apparatus and method. Multiple data sequences with iris images are obtained and divided into locating images and to-be-processed images, wherein the locating images are used for locating iris positions, and the to-be-processed images are used for generating protected iris images according to the iris positions in the locating images. Therefore, an intentional person cannot steal the images with iris features in a transmission process, so that the iris identification security is improved.

Description

technical field [0001] The invention provides an iris image acquisition device, an iris image recognition device and a method thereof, and particularly relates to an iris image acquisition device, an iris image recognition device and a method thereof which prevent iris features from being stolen. Background technique [0002] Iris recognition is recognized by the industry as a biometric technology with a high level of security. The iris has a high degree of uniqueness and stability (it does not change with time after stable development). Therefore, compared with other biometrics, such as fingerprint recognition or face recognition, iris information can be more accurately interpreted and identified. Generally, an iris recognition system is composed of an image acquisition device (such as a camera) and an image processor (such as a computer system). The image acquisition device shoots images with iris characteristics, and transmits the images with iris characteristics to the...
