In this paper, a method for improving the reliability of an Automated Handwritten Signature Verification System (AHSVS) using a short handwritten sentence is realized using a dedicated hardware as a real time DSP system. The necessity of realising hardware based models emerges from the fact that modern DSP systems provide integration of the entire design process and flexibility due to hardware implementation and portability. In system level design, each word of the sentence is used to tackle an individual verification problem. The entire verification procedure is implemented by building both the image processing and classifier design modules using the TMSC6713 DSK and the SIMULINK model builder. The improvement in verification performance is due to both the fusion procedure applied and the full discretion of the writer to choose his own secret word.
