Towards Privacy-Aware Location-Based Database Servers

M.F. Mokbel
2006 22nd International Conference on Data Engineering Workshops (ICDEW'06)  
The wide spread of location-based services results in a strong market for location-detection devices (e.g., GPS-like devices, RFIDs, handheld devices, and cellular phones).  ...  The location-based database server is equipped with additional functionalities that support spatio-temporal queries based on the spatial region received from the location anonymizer rather than the exact  ...  In this case, the location-based database server does not have the exact location information of the person who issued the query while the exact location information of the target objects (i.e., gas stations  ...

Towards a Common Notion of Privacy Leakage on Public Database

Shinsaku Kiyomoto, Keith M. Martin
2010 2010 International Conference on Broadband, Wireless Computing, Communication and Applications  
In particular, this model applies the notion of differential privacy to data sets that satisfy k-anonymity. We demonstrate this approach through a simple case study.  ...  If personal private information is leaked from the data, the service will be regarded as unacceptable by the original owners of the data.  ...  the value for sensitive information in the worst case, where the adversary has background knowledge about a quasiidentifier of a target person.  ...

Towards privacy-preserving integration of distributed heterogeneous data

Pawel Jurczyk, Li Xiong
2008 Proceeding of the 2nd PhD workshop on Information and knowledge management - PIKM '08  
And most importantly, the results should not contain individually identifiable information and institutions should not reveal their databases to each other apart from the query results.  ...  In this paper, we propose a distributed anonymization protocol that allows independent data providers to build a virtual anonymized database from horizontally partitioned databases, and a secure query  ...  We would like to thank Kristen Lefevre for providing the implementation of Mondrian algorithm and the anonymous reviewers for their valuable comments.  ...

Privacy enhancing identity management

Sebastian Clauβ, Dogan Kesdogan, Tobias Kölsch
2005 Proceedings of the 2005 workshop on Digital identity management - DIM '05  
Especially we present the current state of research and mechanisms useful to protect the user's privacy.  ...  However, designing such systems is a complex task, as the expectations of the different parties involved in electronic transactions have to be met.  ...  This is done by queries which are more general than the intended one. With combination of the results one can construct the result of the target query.  ...

The New Casper: A Privacy-Aware Location-Based Database Server

Mohamed F. Mokbel, Chi-Yin Chow, Walid G. Aref
2007 2007 IEEE 23rd International Conference on Data Engineering  
While the location anonymizer is implemented as a stand alone application, the privacy-aware query processor is embedded into PLACE; a research prototype for location-based database servers.  ...  Casper consists of two main components; the location anonymizer that blurs the users' exact location into cloaked spatial regions and the privacy-aware query processor that is responsible on providing  ...  For example, an employer may check on her employee behavior by knowing the places she visits or the personal medical records can be inferred by knowing which clinic a person visits.  ...

Privacy-Preservation for Publishing Sample Availability Data with Personal Identifiers

Ali Gholami, Erwin Laure, Peter Somogyi, Ola Spjuth, Salman Niazi, Jim Dowling
2015 Journal of Medical and Bioengineering  
We realize our solution by having a two-level anonymiziation mechanism, where our toolkit for publishing availability data first pseudonymizes personal identifiers and then anonymizes sensitive attributes  ...  We believe that our toolkit contributes a first step to support the privacy preserving publication of data containing personal identifiers.   ...  ACKNOWLEDGMENT The authors would like to thank Jan-Eric Litton from Karolinska Institutet for his support and Matthias Templ from Vienna University of Technology for helping with the sdcMicro package.  ...

Hippocratic PostgreSQL

Jalaja Padma, Yasin N. Silva, Muhammad U. Arshad, Walid G. Aref
2009 Proceedings / International Conference on Data Engineering  
In many cases this requirement is imposed by laws that recognize the right of data owners to control whom their information is shared with and the purposes for which it can be shared.  ...  Several interesting problems emerge as a result and their solutions are presented in the context of this demo.  ...  The idea of Sensitive Attribute Generalization [9] adds the notion of personalized privacy to the concept of k-anonymity.  ...

Non-interactive differential privacy

2012 Proceedings of the First International Workshop on Open Data - WOD '12  
Differential privacy stands out as a model that provides strong formal guarantees about the anonymity of the participants in a sanitized database.  ...  This paper covers such breakthrough discoveries, by reviewing applications of differential privacy for non-interactive publication of anonymized real-life datasets.  ...  The goal is to optimize the results of range queries, where the analyst asks for the number of people lying under a given query area, usually expressed as an hyperrectangle.  ...

2012 2012 Fourth International Conference on Intelligent Networking and Collaborative Systems  
The number of data collections of person-specific information is increasing exponentially.  ...  Security models, developed for databases, differ in many aspects because they focus on different features of the problem, leading to incomplete implementations of the organizational security strategy.  ...  For a single user case, when a user poses a query, the detection system will examine the user's query log and determine the probability of inferring sensitive information.  ...
