Due to the wide range of opportunities that are provided to us, with which we represent ourselves to others, it is very important to develop the widest possible personalization features to represent our personalities to others. In addition, the personalization using web applications is also important for increasing intuitive usage and finding new users in application interfaces. We are aware that the application interfaces need to be as intuitive and easy to customize, so it is necessary to put great deal of attention to software development, and the program focused on the design and functionality of the user interface, which makes the users narrower or wider, depending on the design's performance. For adapting the software to human needs and providing the best solution, extensive and detailed research is required before making any application. For the purpose of this graduate thesis, an application for defining and recognizing characters based on personal handwriting has been developed. The aim of the thesis is to develop an application that will use the experiential factors to strive for as accurate as possible results for matching and recognizing the user's handwriting. With this application, one transfers his own imagination to a digital form. This application gives one the ability and the pleasure to design ones wishes per one’s own desires and habits. After examining the accuracy of the character matching, the errors will be shown and the possible improvements will be known. With these errors, the application can be revised and upgraded so it would be more precise. Also, with this app, encrypted messages could be developed, which only this app could recognize through vector values.
