Protecting Privacy Against Location-Based Personal Identification

2005
This paper presents a preliminary investigation on the privacy issues involved in the use of location-based services. It is argued that even if the user identity is not explicitly released to the service provider, the geo-localized history of user-requests can act as a quasi-identifier and may be used to access sensitive information about specific ...

LPPS: Location privacy protection for smartphones

2016 IEEE International Conference on Communications (ICC), 2016
Location-based service (LBS) is useful for many applications. However, LBS has raised serious concerns about users' location privacy. Utilizing the computation and storage capacity of smart phones, we propose a novel system architecture, called Location Privacy Protection for Smartphone (LPPS), to provide a privacy-preserving top-k query. LPPS does not

Protecting Location Privacy in Spatial Crowdsourcing

2015
Recently, spatial crowdsourcing has attracted wide attention in both the research community and industry, one of which is the eMarket platform. It enables requesters to release spatial tasks (i.e., tasks related to a location) and expect them to be performed by workers (i.e., users with smart mobile devices).

Location cloaking for location privacy protection and location safety protection

2018
Many applications today rely on location information, yet disclosing such information can present heightened privacy and safety risks. A person's whereabouts, for example, may reveal sensitive private information such as health condition and lifestyle. Location information also has the potential to allow an adversary to physically locate and destroy a ...

A New Location Privacy Protection Algorithm

22017 IEEE International Conference on Computational Science and Engineering (CSE) and IEEE International Conference on Embedded and Ubiquitous Computing (EUC), 2017
The accuracy of user location information is inversely proportional to the user's privacy preserving degree k, and is proportional to quality of query service. In order to balance the conflict between privacy preserving security and query quality caused by the accuracy of location information, A clustering algorithm aiming at eliminating outliers based

The survey of location privacy protection

2012 International Conference on Wavelet Active Media Technology and Information Processing (ICWAMTIP), 2012
For the past few years, the Location-Based Service (LBS) is becoming more and more important for people's life. On the one hand, it is easy to told people that where is they are anytime, On the other hand, the privacy of location issues attract more and more attention.

Collaboration-Based Location Privacy Protection Method

2019 IEEE 2nd International Conference on Electronics Technology (ICET), 2019
In the privacy protection method based on user collaboration, all participants and collaborators must share the maximum anonymity value set in the anonymous group. No user can get better quality of service by reducing the anonymity requirement. In this paper, a privacy protection algorithm random-QBE, which divides query information into blocks and ...

Quantifying and Protecting Location Privacy

2013
Recent developments in information and communication technologies have been profound and life-changing. Most people are now equipped with smart phones with high computation power and communication capabilities. These devices can efficiently run multiple software applications in parallel, store a non-negligible amount of (personal) user data, process ...

Protecting Location Privacy Through Crowd Collaboration

2017
Location-based services (LBSs) enable users to sense their surroundings at the risk of exposing coordinates to attackers. Worse yet, a strong adversary with arbitrary knowledges probably derive more privacy especially in continuous query scenarios. To address the problems, a multi-player privacy game mechanism is proposed to satisfy users’ location ...

Protecting location privacy through Identity Diffusion

2009 International Conference on Ultra Modern Telecommunications & Workshops, 2009
With the proliferation of new online services and wireless personal devices, location-based services and applications for mobile users are widespread in use today. But the privacy of these users exposes to others increasingly in accessing those location based services.
