Palm vein authentication could fit tablets
As there seem to be an escalation among providers of biometric authentication solutions, the dumb fingerprint is now often dismissed as being “insecure” and the next big thing is either multimodal biometrics (taking into account several simple biometric features) or more difficult to extract and near impossible to forge in-depth biometrics such as vein patterns.
Using proprietary optics with a characterized diffraction and angular orientation, the researchers were able to achieve a compact near IR illumination component that lights up a rectangular target area above the a device’s screen (sideways) with a uniform intensity using a single LED. The company has also developed a new verification technology that captures the complete pattern of a palm’s veins, dividing the pattern into slices as one’s hand passes over the optical unit.
This means that the optical unit (including the camera sensor and the near IR LED) only 8mm wide can be embedded into the frames of compact mobile devices and still perform full palm vein authentication as a user slides her/his hand over the screen (following some on-screen guides).
The optical unit continuously captures images of the palm while at the same time, coordinate data obtained from the touch panel is also continuously recorded so as to rebuild a complete picture of the palm veins pattern.
