Mobile devices are ubiquitous today. Billions of smartphones, tablets, and laptops are used for accessing and sharing data anywhere, anytime. Moreover, localization technologies like GPS and Bluetooth beacons such as Apple’s iBeacon or Google Eddystone enable location-based services and geo-social networks. Point of interest finders, navigation services, friend finders, crowd sensing, and location-based online gaming (e.g., Pokémon GO) are just a few examples of such mobile applications and services utilizing the location of users. The advent of further mobile and/or networked devices including wearable devices like fitness trackers, networked vehicles, or in general anything connected to the Internet of Things (IoT) like IP cameras, microphones (e.g., Amazon Echo, Google Home), smart meters, etc. will drastically increase the amount of data collected to offer “smart” health applications, home services, personalized insurances (“pay as you drive”), energy systems (smart grid), etc.

Besides the immense popularity of such mobile and networked devices and “smart” services, they also raise concerns about the privacy of users. Location information does not only reveal the whereabouts of a person, but can also be used to infer other highly privacy-sensitive information like his work place, religious attitude, style of living (e.g., regularly visiting pubs), and much more. Personal health information could be used to raise the premium of an insurance. Sensors embedded into our environment could capture images and conversations of people, and so on.

Therefore, one major question discussed in this seminar is: how can we offer mobile and networked services without compromising user privacy? Anonymization, obfuscation, cryptographic approaches, private information retrieval, differential privacy, are some exemplary methods discussed to this end.

The systems discussed in this seminar are not restricted to mobile systems, but also consider networked systems in general. For instance, we will also discuss Bitcoin and its blockchain concept, or the Tor network in depth in this seminar.

Note that this is an INFOTECH seminar targeting English-speaking students. German-speaking students from computer science and software technology please have a look at our Hauptseminar Prinzipien vernetzter Systeme – Privatheit und Sicherheit in mobilen und vernetzten Systemen.
