Privacy, Data Protection, Digital Identities
The use of modern telecommunications and on-line services involve users' personal information.. For example, using search engines exposes the query terms used, which can be both sensitive and identifying, as illustrated by the exposure of search terms; social networking services expect users to reveal their social connections, messages and preferences, that could lead to direct privacy violation if exposed. Browsing the web also leaves traces of where users have gone, their interests, and their actions - meta-data that can be used to profile individuals.
