+\section{Motivation}
+Digidow is a research project of Prof. Mayrhofer, head of the Institute for Networks and Security (INS).
+The project is aims to be a secure and privacy-friendly solution to identify or authenticate a person to a requester.
+Figure \ref{fig:digidow} shows a graphical overview of the planned identification process in this project.

+After service discovery (1) over a distributed network, a user should be able to be identified by that system.
+When a person intends to get access by this system, she initially should provide a unique ID (2).
+Given this information, the \emph{Verifier} asks the \emph{Biometric Sensor} to gain biometric data of this person(3).
+In fact, one can use any form of data which uniquely identifies a single person.
+Once, this data is retrieved, the Biometric Sensor finds the user's \emph{Personal Agent}, builds trust (4, 6) in between and submits the data subsequently(5).
+Since the Personal Agent holds all required data to identify its corresponding user, it is able to decide whether the claim is correct or not (7).
+Based on that decision, the Verifier can then trigger an adequate reaction(8).
+This system is designed to implement the \emph{Need-To-Know} principle and thus privacy for the user.
+
+\section{Scope of the Thesis}
+This master thesis will cover a major part of the \emph{Biometric Sensor}.
+When a request of the \emph{verifier} appears, the system captures data from the biometric interface, wraps and submits it to the \emph{personal agent}, where further processing is done.
+Two essential questions arise while doing so.
+First, the system has to identify the corresponding personal agent.
+This problem should be solved with the service discovery part.
+Second and more important for this thesis is the question, how the sensor system and the personal agent trusts each other.
+Therefore one is able to generate trust via a \emph{Trusted Platform Module} (TPM).
+Another question is how the system interacts with attached sensors that get the sensible data.
+
+\subsection{Practical Part}
+One goal of this thesis is to set up a system which is \emph{trustworthy}.
+This means that the system's TPM can verify every major part of the executed software (firmware, boot loader, kernel, driver, executed software, firmware of attached devices, \ldots).
+
+Furthermore a program should read data from attached sensors.
+This data should then be sent to the personal agent for further processing.
+Before this can be done, both, Personal Agent and the Biometric Sensor have to trust each other.
+The TPM provides a function called \emph{Direct Anonymous Attestation} to tackle this problem.
+Since the TPM is a passive part in the system, these features have to be accessed with a custom program.
+
+After having this system implemented, a demonstration platform should illustrate how this system works.
+The not yet provided, but required interfaces will be simulated in a way that allow to demonstrate the function of the implemented part of this thesis.
+
+\section{Discussion}
+The implementation and demonstration allows then a discussion about benefits and drawbacks of the implementation and a comparison to other possible implementations. 
+This thesis should cover and discuss the following questions:
+\begin{itemize}
+	\item What is trust?
+	\item How does the TPM benefit to the system's trust?
+	\item What are the limitations by using a TPM?
+	\item What is necessary to trust a system with a TPM?
+	\item How can trust be generated between Personal Agent and Biometric Sensor?
+\end{itemize}
