Privacy-Preserving Aggregate Queries for Optimal Location Selection
Today, vast amounts of location data are collected by various service providers. The location data owners have a good idea of where their customers are most of the time. Other businesses also want to use this information for location analytics, such as finding the optimal location for a new branch. However, location data owners cannot directly share their data with other businesses, mainly due ...
متن کاملPreserving User Location Privacy with Safe Zone for Spatial Queries
Now a days the use of Location Based Services (LBS) gained importance among the users. In most of the cases, users do not want to reveal their personal information to their service providers. Sometimes mobile devices are out of the specified range which cannot be processes by servers. Hence confidentiality, privacy and up to date and optimal answers will be important aspects in location based s...
متن کاملPrivacy-Preserving Verification of Aggregate Queries on Outsourced Database
It is often desirable to be able to guarantee the integrity of historical data, ensuring that any subsequent modifications to the data can be detected. It would be especially convenient to extend such proofs of integrity to certain computations performed later using the historic data. We approach this question in the context of outsourced databases, where a data owner delegates the ability to a...

متن کاملPrivacy Preserving Moving KNN Queries
We present a novel approach that protects trajectory privacy of users who access locationbased services through a moving k nearest neighbor (MkNN) query. An MkNN query continuously returns the k nearest data objects for a moving user (query point). Simply updating a user’s imprecise location such as a region instead of the exact position to a locationbased service provider (LSP) cannot ensure p...
