+abstract="Although many charities have a web presence, almost all of them have been designed to accept credit cards as the only means for making donations. The anonymity requirements of many donors, however, make the existing means of donation inappropriate for them. In this paper we investigate the business need for an internet charity donation scheme, identify the security requirements such a scheme should fulfill, and propose a scheme that uses an anonymous electronic cash technique to make donations, and that employs smart cards for donation distribution. Finally, we analyse how the proposed scheme matches the identified security requirements.",

\maketitle
\begin{abstract}
+ Privacy-preserving donations have complex requirements that also
+ vary by country. Building on privacy-friendly digital cash protocols
+ (which enable customers to pay anonymously using blind signatures)
+ we created the {\em Donau} system to handle key use-cases for donations.
+ This paper explains how our Free Software implementation addresses the
+ most common requirements, and also elaborates how others could be
+ instantiated with significant changes or additions to the design.
+
+ The Donau system achieves privacy for donors while providing
+ them with a proof that they donated to some registered charity.
+ The charity does not learn the identity of the donor and the tax
+ authority does not learn which charities received donations from
+ a particular donor. However, authorities do learn the total amount
+ donated to a charity by all donors.
+
+ Our design introduces a new entity, the {\em Donation Authority}
+ which operates the {\em Donau} service. The {\em Donau} would typically
+ be operated by or on behalf of the tax authority and ensures that
+ only recognized charities can register and provide proofs to their
+ donors.
+
+ Society would benefit from the Donau system as it simplifies
+ filing taxes, contributes to fair taxation, and eliminates
+ privacy-concerns from charitable giving.

GNU Taler is a privacy-friendly payment protocol that offers full anonymity to
the customer, making their purchases anonymous and unlinkable not only to
third parties but even to merchants and banks involved. While this payment
