Abstract:
1. A biometrics signal input device to be connected to a computer apparatus, the computer apparatus mainly comprising a central processing unit (CPU), a main memory, a BIOS (Basic Input/Output System) ROM (Read Only Memory) chip, a main storage device, a user interface and a host interface, through which the biometrics signal input device is connected to the host interface, the biometrics signal input device comprising: a controller for providing a device interface to be connected to the host interface; a biometrics sensor connected to the controller; and a memory connected to the controller, wherein: when the computer apparatus is turned on, a hardware detecting and initializing operation is performed using a program code in the BIOS ROM chip to detect and initialize the CPU, the main memory, the user interface and the host interface; when the biometrics signal input device connected to the host interface is detected, the hardware detecting and initializing operation is paused, and programs or data stored in the memory of the biometrics signal input device is downloaded to the computer apparatus and executed or processed, so that an operation environment is established; the CPU enables a biometrics matching and application program in the operation environment so as to provide a human-machine interface to guide a user to use the biometrics sensor to perform a biometrics data matching operation; in the biometrics data matching operation, the human-machine interface guides a to-be-identified user to perform an authentication procedure, the controller controls the biometrics sensor to sense to-be-identified biometrics data of the to-be-identified user, the CPU reads and processes the to-be-identified biometrics data from the controller and compares the processed to-be-identified biometrics data and biometrics template data stored in the memory of the biometrics signal input device, and the hardware detecting and initializing operation is continued, if the processed to-be-identified biometrics data and the biometrics template data match with each other, so as to detect and initialize the main storage device and enable a main operation system stored in the main storage device to be loaded into the CPU and executed to complete a booting operation, wherein the main storage device is detected and initialized after the processed to-be-identified biometrics data and the biometrics template data match with each other, and after the CPU, the main memory, the user interface and the host interface are detected and initialized; and the operation environment is established before the biometrics sensor senses the to-be-identified biometrics data of the to-be-identified user.
