+<h3>Abstract</h3>
+<p>
+ Subscription-based services are more popular than ever, with a significant portion of digital goods, such as newspaper
+ articles, music, movies, and TV shows, sold through this business model. These services are generally tied to a user
+ account. As a result, the use of a subscription leaves a data trail. Service providers can use collected usage data to
+ build a personality profile that can reveal information about political views, sexual orientation, health
+ complications, or other sensitive topics.
+</p>
+<p>
+ This information, in the wrong hands, can have critical implications, especially in regions with repressive regimes.
+ Ideally, a solution to this problem also addresses the challenge of subscribers sharing their credentials with groups
+ of people online.
+</p>
+<p>
+ This thesis presents a solution for account-less and privacy-preserving subscriptions based on GNU Taler. The solution
+ is convenient for customers, affordable for merchants, and resistant to abusive sharing of subscriptions.
+ Subscriptions are valid during a configured timeframe, while usage during that timeframe is unlimited. The flexible
+ design of the solution allows it to be used for a wide array of use cases beyond subscriptions, such as discounts,
+ loyalty stamps, multi-entry event ticketing, membership programs, deposit systems, and privacy-preserving gifts. In
+ addition, the solution's low operational costs, coupled with its built-in protection against abusive sharing of
+ subscriptions, make it highly attractive to merchants.
+</p>
+<p>
+ The solution is implemented in the GNU Taler merchant component as free and open source software. The integration into
+ the GNU Taler wallets is subject to future work. Furthermore, to inform customers about the degree of anonymity for a
+ given subscription, an additional service for authorizing the anonymity set size of subscriptions is proposed.

+<h2>Donau - Tax Deductable Donations with Privacy</h2>
+
<p>
-The Donau system is a new type of a donation authority system. It is free software with focus on privacy and anonymity. It depends on the code of the GNU Taler environment, but is completely independent of the Taler payment system.

-The verifiability of the donations receipts eliminates tax fraud. Furthermore, the new possibility to combine donation receipts increases the user convenience of the Donor and tax auditor.
