5.4 Under which operating systems does the ID Mouse run?
Win 98, 98se, Win NT 4.0 as of Service Pack 3 or higher and Windows 2000.
5.5 How does FingerTIPTM work?
The FingerTIPTM module, the core of the ID Mouse, enables the fingerprint to be reliably read
in and evaluated and can be used in various ways.
When a finger is lying on the sensor, 65'000 sensor electrodes measure the exact distance
between the skin surface and the sensor. The integrated software optimizes recognition
performance both for generating the reference data record and for every subsequent check.
With a surface area of less than 160 mm2, the biometric sensor can also be used in very
small devices. In less than 100 ms the sensor generates a digitized gray-scale image of the
fingerprint. Image processing software looks for the characteristic features of the fingerprint
("minutiae") and stores their position and orientation. When a fingerprint is checked later on,
an evaluation algorithm compares the sensor image with the previously stored reference
data. The release signal comes from the sensor chip only if both data records match. The
reference data is stored in the local memory. The identification or verification is carried out
within the computer. It is not the entire fingerprint which is stored as the reference data
record, but rather a few characteristic features from which the original fingerprint cannot be
reconstructed.
What also makes the FingerTIPTM stand out is its low power consumption. This enables use
in mobile devices such as laptops and mobile phones in particular. A further feature of the
sensor is its sleep mode. Its construction, developed especially for this product, facilitates
integration of the FingerTIPTM into the most varied of devices. A flexible printed board bridges
the gap between the sensor on the surface of the device and the data-processing chip at its
interior. It offers the designer a certain degree of flexibility when deciding where to mount the
sensor on the device. The DIN (German standard) plug connection enables soldering in
standard SMD (Surface Mounted Device) technology. The FingerTIPTM is manufactured in
standard CMOS technology as is used for the production of integrated circuits. It thus offers a
low-cost introduction to the use of biometric systems.
5.6 How can you bypass logon under Win 98 if, for example, the ID Mouse is
defective?
The computer must be started up with a startup disk under MS-DOS.
Switch to the ID Mouse folder:
default:
c:\progr~1\idmouse
The login entry must be deactivated with ren login.exe loginold.exe.
Note: This will only work if you have not set your PC to shut down automatically.
