Biometric authentication of a user using online dynamic signature

It is very challenging task to recognize user action and reaction corresponding to that in real time. Online dynamic signature stands for capturing signature of a person in real time whenever and wherever it is required. In this paper, we are designing a prototype consisting of a digital tablet, pen and microcontroller transmission board to sense the online gesture and collect the same. Personal computer receives the signature transmitted by the transmitter that is connected to digital tablet. Acceleration that obtains instantaneously, rotation, as well as other various informations are captured by dynamic data for signing procedure. Later recording the captured information, preprocessing steps will be carried out in which unwanted noise information will be eliminated. Using the proposed algorithm we are able to authenticate the user effectively. False rejection rate and even the false rate of acceptance are low by using this method. Our work has been found to provide better accuracy and validation result compared to existing works.
