Identity authentication device
View Patent ↗An identity authentication device is stylus-shaped. A processor is disposed within the device. The stylus-shaped device includes a scanner-type device component for capturing within the processor memory a written signature generated by the stylus while the stylus is writing upon a surface. A fingerprint sensor is disposed within the grip of the stylus. The fingerprint sensor enables the capture of a digital signature of the writer at the same time that the written signature of the writer is captured. Once the identity of the writer has been authenticated by comparison against a reference print, the signature of the writer irrefutable. The device serves the same general purpose and can be used in lieu of a signature pad. The device is either attached to a surface or is portable and wireless.
1. An identity authentication device having the general shape of a stylus, the stylus having a stylus tip, the identity authentication device comprising:
a sensor disposed within the grip of the stylus, the sensor enabling the capture of a fingerprint or a thumbprint as the stylus is generating text images upon a surface, either the fingerprint or thumbprint enabling identity authentication of the person doing the writing, the text images being a signature or non-signature images; and
a processor having memory, the memory being disposed within the stylus, the stylus including means for determining the position of the tip of the stylus upon the surface, the text images being captured in processor memory as the writing is generated by the stylus, the processor memory retaining the text images generated by the stylus upon the surface;
whereby identity authentication is based upon a comparison of either the captured fingerprint or thumbprint against a reference print, such identity authentication being independent of the text images; and
whereby the text images generated by the stylus are downloadable from the scanned text images retained in the processor memory within the stylus.

a sensor enabling the capture of a fingerprint or a thumbprint as the stylus is generating text images upon a surface, the fingerprint or thumbprint enabling identity authentication of a person doing the writing, the text images being a signature or non-signature images; and
a processor having memory, the memory being disposed within the stylus, the stylus including a scanner-type device, the scanner-type device for scanning text images generated by the stylus upon the surface, all of the text images being captured in processor memory as the writing is generated by the stylus, the processor memory retaining the text images generated by the stylus upon the surface;
whereby identity authentication is based upon a comparison of either the captured fingerprint or thumbprint against a reference print, such identity authentication being independent of the text images; and whereby the text images generated by the stylus are downloadable from the scanned text images retained in the processor memory within the stylus.

a processor having memory, the memory being disposed within the stylus, the processor tracking the position of the stylus tip as the text images are being generated upon the writing surface, the position of the stylus tip relative to the surface being tracked by infrared emissions received by the stylus and stored in the processor memory as the writing is generated by the stylus;
whereby identity authentication is based upon a comparison of the captured fingerprint or thumbprint against a reference print, such identity authentication being independent of the text images; and whereby the text images generated by the stylus are downloadable from the scanned text images retained in the processor memory within the stylus.
