  • Patent number: 7669047
    Abstract: A biometrics signal input device with a USB interface is connected to a computer apparatus to control BIOS booting procedures of the computer apparatus. The computer apparatus communicates with a USB controller of the input device through the USB interface according to a USB communication protocol and regards this device as a USB device. Then, the computer apparatus executes a program stored in a memory of the input device and enables a biometrics sensor to read biometrics data of a user. Then, to-be-identified biometrics data and biometrics template data pre-stored in the memory are transferred to a main memory of the computer apparatus. A CPU of the computer apparatus compares the to-be-identified biometrics data with the biometrics template data. After the comparison passes, the BIOS booting procedures are allowed to be continued until the CPU has completely loaded an operation system stored in a main storage device of the computer apparatus.

  • Patent number: 7606440
    Abstract: In a linear image sensing device with image matching function, a linear sensors array senses a finger, which is moving over it, to obtain fragment image analog signals, which are amplified, by a programmable gain amplifier, into amplified signals. An analog-to-digital converter sequentially converts the amplified signals into digital image signals. An image matching module sequentially receives and processes adjacent two of the digital image signals, and outputs continuous non-overlapped fragment images through an input/output interface. A control logic controls operations and communications of the above-mentioned components. A terminal system receives the non-overlapped fragment images and assembles the non-overlapped fragment images into a complete fingerprint image in a manner of stacking the images side by side.

  • Patent number: 7539830
    Abstract: A portable storage device capable of automatically running biometrics application programs includes a control module, a storage unit and a biometrics sensor. The control module, in which firmware is stored, is electrically connected to a terminal host, a storage unit and a biometrics sensor. The firmware is configured to divide the storage unit into a plurality of blocks including a biometrics application program block and a private block. The biometrics application program block stores at least one biometrics application program. The firmware enables an operation system of the terminal host to treat the biometrics application program block as an compact disk drive and disables or closes the compact disk drive after automatic running the at least one biometrics application program. The least one biometrics application program guides a user to perform a biometrics identification procedure, and then enables a specific operation.

  • Patent number: 7519829
    Abstract: A storage device to be connected to a terminal host includes a control module to be connected to the host, and a biometrics sensor and a storage unit both connected to the control module. The host runs a biometrics application program (AP) to inform the control module to control the sensor to read to-be-identified biometrics data of a user and to determine whether the to-be-identified biometrics data matches with biometrics template data stored in the storage device. When the two sets of data match with each other, the host runs a host-specific-code generating program to generate and transfer a host specific code to the control module. The control module generates a device specific code using a device-specific-code generating program stored therein, determines whether the codes match with each other, and enables the host to access a data protection unit of the storage device when the codes match with each other.

  • Publication number: 20080091399
    Abstract: A driverless signal generating apparatus to be connected to a computer host includes a signal generator and an interface controller, which is connected to the signal generator and has operation firmware stored therein. The operation firmware simulates the signal generating apparatus as a standard device. A driver corresponding to the standard device has been built in an operation system (OS) of the computer host. The operation firmware receives a first command outputted from the OS through the driver and makes the OS identify an attribute of the signal generating apparatus in response to the first command. An application program (AP) may be executed in the OS to generate a second command. The first and second commands pertain to a control transfer command for enabling control transfer. The firmware receives the second command and thus controls the signal generator to generate an external signal to be sent back to the OS.
