    Unwillingness to pay for privacy: A field experiment

    We measure willingness to pay for privacy in a field experiment. Participants were given the choice to buy a maximum of one DVD from one of two online stores. One store consistently required more sensitive personal data than the other, but otherwise the stores were identical. In one treatment, DVDs were one Euro cheaper at the store requesting more personal information, and almost all buyers chose the cheaper store. Surprisingly, in the second treatment when prices were identical, participants bought from both shops equally often. -- Wir messen die Zahlungsbereitschaft fĂŒr Datenschutz in einem Feldexperiment.

    Execution Models for Choreographies and Cryptoprotocols

    A choreography describes a transaction in which several principals interact. Since choreographies frequently describe business processes affecting substantial assets, we need a security infrastructure in order to implement them safely. As part of a line of work devoted to generating cryptoprotocols from choreographies, we focus here on the execution models suited to the two levels. We give a strand-style semantics for choreographies, and propose a special execution model in which choreography-level messages are faithfully delivered exactly once. We adapt this model to handle multiparty protocols in which some participants may be compromised. At level of cryptoprotocols, we use the standard Dolev-Yao execution model, with one alteration. Since many implementations use a "nonce cache" to discard multiply delivered messages, we provide a semantics for at-most-once delivery

    A data sharing platform for earables research

    Get PDF
    Ear-worn wearable devices, or earables, are a rapidly emerging sensor platform, with unique opportunities to collect a wide variety of sensor data, and build systems with novel human-computer interaction components. At this point in the development of the field, with projects such as eSense putting hardware in researchers' hands but being limited in reach, the sharing of datasets collected by researchers with the wider community would bring a number of benefits. A central data sharing platform would enable wider participation in earables research and improve the quality of projects, as well as being a vehicle for better data quality and data protection practices. We discuss the considerations behind building such a platform, and propose an architecture that would achieve better privacy-utility trade-offs than many existing data sharing efforts
