Personal computer with a biometric sensor having improved resistance to environmental distortions |
摘要 |
The present invention is a personal computer system and method including a biometric sensor which is protected from environmental forces and which resists certain attacks by sensing whether a living person is providing the biometric identification. A second sensor provides an input as to whether the biometric input is from a living person, through the sensing of a life-indicative parameter such as an appropriate level of blood oxygen in the sensed item, and the sensors are covered by a removal cover which provides electrostatic discharge when the cover is opened.
