While prior studies have provided us with an initial understanding of people’s location-sharing privacy preferences, they have been limited to Western countries and have not investigated the impact of the granularity of location disclosures on people’s privacy preferences. We report findings of a three-week comparative study collecting location tra...

Disclosing the current location of a person can seriously affect their privacy, but many apps request location information to provide location-based services. Simultaneously, these apps provide only crude controls for location privacy settings (sharing all or nothing). There is an ongoing discussion about rights of users regarding their location privacy (e.g. in the context of the General Data Protection Regulation – GDPR). GDPR requires data collectors to notify users about data collection and to provide them with opt-out options. To address these requirements, we propose a set of user interface (UI) controls for fine-grained management of location privacy settings based on privacy theory (Westin), privacy by design principles and general UI design principles. The UI notifies users about the state of location data sharing and provides controls for adjusting location sharing preferences. It addresses three key issues: whom to share location with, when to share it, and where to share it. Results of a user study (N=23) indicate that (1) the proposed interface led to a greater sense of control, that (2) it was usable and well received, and that (3) participants were keen on using it in real life. Our findings can inform the development of interfaces to manage location privacy.

As computing resources are becoming more powerful and less costly, they give rise to new applications and services. Location Based Service is the next step forward to
facilitate context-aware services backed by recent advances in technologies. It allows industries to promote their services in a user-focused approach. In this perspective, mobile phone business plays an influential role and introduces trends in the way individuals communicate and share experience in unprecedented ways.
Location Based Services are involved in many aspects of our lives, including emergency cases and marketing activities. But deployment of such a technology cannot be without its drawbacks. Due to the mobile nature of such devices, location information can be obtained continuously, and the major concern in that regard is location privacy. Furthermore, reliability of using such services is important to ensure a convenient user experience. Thus, it is important to understand the obstacles that face LBS utilisation despite the future aspirations it promises and how they might be surmounted.
This thesis attempts to investigate mainly the two areas of privacy and security by
identifying the threats facing location information generally and that of LBS
information particularly. Also it presents the concerns that users of LBS may raise as a result of using LBS. Finally, relevant metrics are presented as possible answers to some of the threats.
Location sharing is a popular feature of online social networks, but challenges remain in the effective presentation of privacy choices to users, whose location sharing preferences are complex and diverse. One proposed approach for capturing these nuances builds on the observation that key attributes of users' location sharing preferences can be represented by a small number of privacy profiles, which can provide a basis for configuring individual preferences. However, the impact of this approach on how users view their privacy is relatively unknown. We present a study evaluating the impact of this approach on users' location sharing preferences and their satisfaction with the decisions made by their resulting settings. The results suggest that this approach can influence users to share significantly more without a substantial difference in comfort. This further suggests that the provision of profiles for privacy settings must be carefully considered, as they can substantially alter sharing behavior.
