This study Aims to research and develop identity verification using freeware. For optimization of workflow systems authentication systems. This research is a research and software development. To be applied to the management system to verify identity. The development process of the study process the performance of the verification system . To software development It is a tool used for development . Program for the development of the Linux operating system . The results of research Such programs can be used to produce real target audience is the personnel of the agency. This research has made evaluating its use for system identification using freeware. Users have found that satisfaction with the program was good .

This research presented an online approach to verify entire Thai Fingerprint through fingerprint scanner U.are.U 4000 model using Hausdorff Distance Technique for similarity measurements. The Fingerprint Verification Using Hausdorff Distance Technique system consists of image preprocessing minutia feature extraction from two type (ridge ending and bifurcation) and verification process. In the image preprocessing include brightness enhancement contrast enhancement orientation field frequency ridge gabor filtering binarization and thinning which are sufficient to enhance the image for feature extraction. Only features extraction was recorded for fingerprint verification. The experimental result demonstrates 93.33% of verification accuracy.
