Abstract
Whoever conducts a survey usually wants a large number of participants in order to attain meaningful results. A method to increase the motivation of potential participants is offering a prize that is awarded to one of them. For that purpose the pollster usually collects the E-mail addresses or other personal data of the participants, enabling him to notify the winner. Collecting the participant’s personal data may, however, conflict with the potential participant’s privacy interests as well as the pollster’s concern about dishonest answers participants may give to gain favor. Therefore, this paper presents solutions that enable the pollster to carry out a survey in an anonymous way while only collecting the winner’s personal data. If the prize is a virtual good, then even the winner’s identity is concealed.
