Signature verification is probably one of the oldest widespread and used biometrical identification method. We use our signature day by day to authenticate contracts or various form, so an automatized signature verification system would be useful, which is able to recognise our signature with great precision.

In the past decades the analyses of handwritten signatures was an intensive research area, but even with the highest precision methods many questions remained. At the Department of Automation and Applied Informatics of Budapest University of Technology and Economics a new, computer based signature verification system has been implemented, and the topic is still an active research area. At the first stage the system examines the signatures, and then based on the main features of the analysed patterns will be able to decide whether the currently unknown signature is original or a forgery.

My task was to introduce the above research results for the public audience. So I’ve implemented two separate application for two different platform, which lead the current user through the processes of the developed signature validation system. The apps not only aimed the experts of the topic, but the users can discover the validation process flow without any related knowledge or competence. With a webcamera the users can directly upload their own signatures and be able to test the accuracy of the validation system. For the experts there is the possibility to construct custom validation configuration and run the application according to their concept.

The first application has been implemented for Silverlight platform to ensure web interface for the users. That can be used without any installation via browser with the well-known desktop user experience.

The other one has been deployed for Windows 8.1 platform and aimed to run on supported tablets and computers. Take advantage of the new platform follows the principles of modern user experience and multiply that with useful animations.
