An Alternative Approach to k-Anonymity for Location-Based Services
Users of location-based services (LBSs) may have serious privacy concerns when using these technologies since their location can be utilized by adversaries to infer privacy-sensitive information about them. In this work, we analyze the mainstream anonymity solutions proposed for LBSs based on k-anonymity, and point out that these do not follow the safe assumptions as per the original definition...
متن کاملAnonymity and Historical-Anonymity in Location-Based Services
The problem of protecting user’s privacy in Location-Based Services (LBS) has been extensively studied recently and several defense techniques have been proposed. In this contribution, we first present a categorization of privacy attacks and related defenses. Then, we consider the class of defense techniques that aim at providing privacy through anonymity and in particular algorithms achieving ...
متن کاملK-Anonymity based Privacy-Preserving location Monitoring Services for Wireless Sensor Networks
Wireless sensor technologies gave rise to many new applications widely used by general citizens as well as military operations. Numerous cases of these applications are based on the information of personal locations. Observations of these locations with untrusted server cause privacy threats to the individuals being monitored. To deal with such a privacy break, the concept of aggregate location...
متن کاملA K-Anonymity Based Schema for Location Privacy Preservation
In recent years, with the development of mobile devices, the location based services (LBSs) have become more and more prevailing and most applications installed on these devices call for location information. Yet, the untrusted LBS provider can collect these location information, which may potentially threaten users’ location privacy. In view of this challenge, we propose a two-tier schema for ...
متن کاملk-Concealment: An Alternative Model of k-Type Anonymity
We introduce a new model of k-type anonymity, called k-concealment, as an alternative to the well-known model of k-anonymity. This new model achieves similar privacy goals as kanonymity: While in k-anonymity one generalizes the table records so that each one of them becomes equal to at least k− 1 other records, when projected on the subset of quasi-identifiers, k-concealment proposes to general...
