+\end{frame}
+ \begin{frame}{Motivation}
+ Issues:
+ \begin{enumerate}
+ \item \textbf{Privacy} concerns:
+ \begin{itemize}
+ \item Targeted advertisement, opinion shaping.
+ \item ``Public safety'': Mass surveillance and data collection.
+ \end{itemize}
+ \pause
+ \item \textbf{Liability} risks:
+ \begin{itemize}
+ \item Data loss through leaks or hacks may result in existential
legal implications (GDPR).
+ \end{itemize}
+ \pause
+ \item \textbf{Oligopoly}:
+ \begin{itemize}
+ \item ``There can be only one (two)''.
+ \item IdP market tends to degenerate.
+ \item Federation not widely used.
+ \end{itemize}
+ \end{enumerate}
+ \end{frame}
+
+\begin{frame}{Approach}
+ \textbf{Primary objective}: We must enable users to exercise their right to
digital self-determination:
+ \begin{enumerate}
+ \pause
+ \item Avoid third party services for identity management and data
sharing.
+ \pause
+ \item Open, free and decentralized service which is not under the
control of a single organization, consortium or business.
+ \pause
+ \item Free software.
+ \end{enumerate}
+ \pause
+ $\Rightarrow$ Empower users to \textbf{reclaim} control over their digital
identities.
+ \end{frame}
+
+
+ \begin{frame}{What does an IdP do?}
+ \begin{enumerate}
+ \item Identity provisioning and access control
+ \begin{itemize}
+ \item Allow management of identities and personal data.
+ \item Facilitate sharing of identity data with third parties.
+ \item Provide up-to-date information accessible even if user is
offline.
+ \item Enforce authorization decisions of user.
+ \uncover<3->{\item[$\Rightarrow$] \textbf {re:claimID}}
+ \end{itemize}
+ \pause
+ {\color<3->{gray}
+ \item Identity information verification and attestation:
+ \begin{itemize}
+ {\color<3->{gray}
+ \item ``this is Alice's email address'': Email provider.
+ \item ``this person is living in Germany'': Sovereign state.
+ \uncover<3->{\item[$\Rightarrow$] \textbf {Not our department!*}}
+ }
+ \end{itemize}
+ \uncover<3->{\tiny{*We will revisit this further on.}}
+ }
+ \end{enumerate}
+ %\begin{enumerate}
+ % \item Identities and attributes must be shared over a secure,
decentralized storage to allow access even of user is offline
+ % \item Access control on data without trusted entity that enforces
authorization decisions by user of he is offline

+\begin{frame}{Managing and publishing identity information}
+ \centering
+ \includegraphics[width=1\textwidth]{Reclaim-2}
+\end{frame}
+
+\begin{frame}{The GNU Name System}
+ \begin{itemize}
+ \item In GNS, a namespace is defined by a public/private EC key pair:
+ \begin{itemize}
+ \item $x$: Private key
+ \item $P$: Public key
+ \item $G$: Generator of the curve
+ \item $n$: Group order
+ \end{itemize}
+ \pause
+ \item Records are encrypted and signed using keys derived from $(x,P)$.
+ \pause
+ \item Encrypted records are published in a distributed hash table (under
key $q$).
+ \pause
+ \item Any peer is able to verify the signature as the corresponding
derived public key is also published.
+ \pause
+ \item Records can only be resolved and decrypted if the true identity and
the label is known.
+ \pause
+ \item[$\Rightarrow$] Namespaces \textbf{cannot} be enumerated and
queries/responses \textbf{cannot}* be observed.
+ \end{itemize}
+ \tiny{*Unless label and identity are known.}
+\end{frame}
+
+\begin{frame}{Identity attributes in GNS}
+ Users may create a namespace $(x,P)$ and use it as a digital identity
containing personal information:
+ \begin{table}[h]
+ \begin{tabular}{|c|c|c|}
+ \hline
+ Label & Record Type & Value \\\hline\hline
+ $l_{email}$ & \texttt{ATTR} & ``email=alice@example.com''\\\hline

+ $l_{dob}$ & \texttt{ATTR} & ``dob=1.3.1987'' \\\hline
+ \end{tabular}
+ \end{table}
+ where the labels are \textbf{random secret values} with high entropy.
+\end{frame}
+
+
+\begin{frame}{Publishing information}
+ Given a namespace $(x,P)$, we can treat labels as shared secrets in order to
selectively disclose information.

OpenID Connect IdP.

+\section{Who sais that, anyway?}
+
+\begin{frame}{Attestations}
+ \centering
+ \begin{itemize}
+ \item Sometimes we need third party assurances to establish trust in
identities.
+ \pause
+ \item Currently, IdPs such as Facebook/Google implicitly provide this
assurance (i.e. vouch for the truthfulness and correctness).
+ \pause
+ \item Claim: Those parties are not actually the authorities over (most of)
your personal data! Examples:
+ \begin{itemize}
+ \item Real name (State/Self-asserted/Other organization)
+ \item Phone number (Provider)
+ \item Address (State/Self-asserted)
+ \item Citizenship (State)
+ \item Age (State)
+ \item Email address (Mail provider)
+ \end{itemize}
+ \end{itemize}
+\end{frame}
+
+\begin{frame}{Attestations}
+ \centering
+ \begin{itemize}
+ \item What users actually need is a \textbf{collection of credentials}.
+ \pause
+ \item Those credentials are issued by a \textbf{variety of different
entities}, including the user.
+ \pause
+ \item Credentials are ideally \textbf{preserving the privacy} of the
individual, e.g. using zero-knowledge proofs.
+ \pause
+ \item Those ideas are already finding their way into standards:
+ \begin{itemize}
+ \item W3C: ``Verifiable Credentials''
+ \item OpenID Connect: ``Aggregated Claims'' \uncover<5->{$\Leftarrow$
\textbf{working on it}.}
