Dynamic Signature Recognition is one of the highly accurate biometric traits. We capture live signature of the person hence it is possible to have dynamic characteristics of signature for matching purpose. The signature captured by digitizer hardware is in the form of discreet points; we have observed that because of speed limitations of the hardware we get signature points with small time gap causing loss of information in between two points. Here we propose a system to suppress the loss of point and calculate intermediate point location. We have proposed use of Digital Difference Analyzer (DDA) algorithm with certain modifications for the interpolation of points. This method gives fair reconstruction of dynamic signature with captured multidimensional features.
