QUALIFIED ELECTRONIC SIGNATURE DEVICE IN THE FORM OF STYLUS AND METHOD OF ITS USE

摘要

A qualified electronic signature device in the form of stylus and method of its use wherein a smart stylus contains a stylus tip, a smart card chip, a processing unit with memory, motion sensor, pressure sensor, a RF transceiver, power control button, LED diode, integrated battery and real-time clock module. The device further contains an external computing device and an electronic dataset. A smart stylus enables qualified electronic signature by means of identifying the signatory via hand written characteristics and behavioural features. At least one characteristic trait of a person who signs an electronic dataset is captured for evaluation. Subsequently, to authenticate the signatory, the captured electronic dataset is evaluated against behavioural templates stored in smart stylus prior to authentication. Upon successfully authenticated signatory, an integrated smart card chip digitally signs an electronic dataset fingerprint obtained via RF transceiver from an external computing device presenting the electronic dataset.
