Abstract
Spoľahlivá autorizácia a overovanie identity sa v súčasnosti stávajú nevyhnutnými pre mnohé každodenné činnosti akými sú nastupovanie do lietadla, prevádzanie finančných operácií apod. Táto práca pojednáva o možnostiach návrhu vhodnej metódy získavania, spracovania a vyhodnotenia dát z tabletu ako takého, so zameraním na možnosť získavať dáta z grafického tabletu použitého v spojení s osobným počítačom, pre účely overenia identity. Obsahuje prehľad biometrie, ako samostante sa rozvíjajúcej vednej disciplíny v priebehu posledných desaťročí 20. storočia až po súčasnosť, súhrn vývoja grafických tabletov, aktuálny stav v súčasnosti, stručný prehľad najrozšírenejších technológií využívaných pri ich konštrukcii a samotné rozdelenie. Ďalej sa zameriava na návrh a popis implementácie vhodného postupu získavania dát z poskytnutého tabletu Trust TB - 7300, s využitím dostupného vývojového balíka pre Tablet PC spoločnosti Microsoft, a porovnanie modelu WinForms a WPF (.NET Framework) za súčasného deklarovania vhodnosti použitia práve druhého z nich. V neposlednom rade je, na základe odozvy od dostupnej množiny užívateľov, kladený dôraz na návrh vhodných typov vstupných dát, testovacích vzorov, vhodnej metódy a aplikácie pre zber a spracovanie dát získaných z grafického tabletu, ako aj ich použitie pre proces overenia identity daného jedinca. V konečnom dôsledku je tak možné previesť zhodnotenie presnosti danej metódy na množine užívateľov, jej vhodnosti pre použitie a nedostatkov. Na základe analýzy danej problematiky je možné navrhnutú metódu prehlásiť za nedostatočne optimálnu – je totiž bezpečná, ale nepresná s malou mierou stálosti a opakovateľnosti. Jedná sa však len o prvotný návrh, pričom použitie v aplikáciách každodenného života je zatiaľ nemožné a proces prechodu z laboratórnych podmienok by si vyžiadal ďalšie pokračovanie v testovaní a zdokonaľovaní postupu.
Reliable authorization and authentication is now becoming necessary for many everyday activities such as boarding an aircraft, doing financial transactions etc. This work deals with the possibility of proposing an appropriate method of acquisition, processing and evaluation of data from the tablet itself, focusing on the possibility of obtaining data from the graphics tablet used in conjunction with a personal computer, for the purpose of verifying identity. It contains an overview of biometrics, as independent developing science over the last decades of the 20th century to the present, a summary of the development of a graphics tablet, the current situation, a brief overview of the most popular technologies used in their construction and distribution. Furthermore, it focuses on the design and implementation of appropriate procedures to obtain data provided by the Trust tablet TB - 7300, using available software development kit for the Microsoft Tablet PC, and a comparison of WinForms and WPF model (.NET Framework), with the declaration of suitability for the use of the second one. Last but not least, according to the response from the available set of users, this work focuses on the design of appropriate types of input data, test patterns, method and application for collecting and processing data from the graphic tablet, as well as their use for the verification of the identity of the individual. Ultimately, it is possible to discuss the accuracy of the method on a set of users, its suitability for use and shortcomings. Based on the analysis of the issue, the proposed method can be declared as under-optimal - it is safe, but inaccurate with low stability and repeatability. It is also important to accent that this is just the initial proposal, the use of applications in everyday life is for current phase impossible and the transition from laboratory conditions would require further development and improvement of the process.
