Content of the Course


Buying groceries is a task of which most people are affected regularly. Although making purchase decisions is a common and recurring process, it is still a complex task characterized by a lack of transparency and decisions made under uncertainty. As a result, consumers are using their mobile devices more and more to support their buying decisions while shopping. This trend has been identified by producers and service providers alike and different mobile product information services are available for consumers nowadays. On the other hand, numerous studies have shown that consumers have a growing concern of digital privacy on the Internet. At the same time, privacy-enhancing technologies (PETs) are gaining a new momentum in academia and industry as a way forward to minimize the down side of digital privacy breach. A typical example of PETs are Attribute-based Credentials (ABCs). ABCs allow users to access information services with minimal disclosure of personal identifying digital data. However, the adoption of PETs in general and ABCs in particular by end users have not been studied thoroughly. There are many factors to consider when emphasizing on the factors affecting the acceptance of ABCs, one of which is the lack of a user-centered design and development. The objective of this seminar is, therefore, to let students familiarize themselves with PETs and especially ABCs as well as carry out scientific investigations on their usability and adaptability challenges. The students will also research how mobile product information services can help to overcome the information asymmetry between the consumer and the producer.
