The pervasiveness of location-aware devices has spawned extensive research in trajectory data mining, resulting in many important real-life applications. Yet, the privacy issue in sharing trajectory data among different parties often creates an obstacle for effective data mining. In this paper, we study the challenges of anonymizing trajectory data: high dimensionality, sparseness, and sequenti...
Development of online social networks and publication of social network data has led to the risk of leakage of confidential information of individuals. This requires the preservation of privacy before such network data is published by service providers. Privacy in online social networks data has been of utmost concern in recent years. Hence, the research in this field is still in its early year...
This paper outlines current research in progress for the creation of a set of privacy heuristics, incorporated into a framework for privacy preserving open source publishing of public body information. It explains how HCI may result in privacy being compromised if information is published without first considering what privacy implications such publication might have. The paper then goes on to ...
In this paper, we propose an effective microaggregation algorithm to produce a more useful protected data for publishing. Microaggregation is mapped to a clustering problem with known minimum and maximum group size constraints. In this scheme, the goal is to cluster n records into groups of at least k and at most 2k_1 records, such that the sum of the within-group squ...

Outsourced data publishing is a promising approach to achieve higher distribution efficiency, greater data survivability, and lower management cost. In outsourced data publishing (sometimes referred to as third-party publishing), a data owner gives the content of databases to multiple publishers which answer queries sent by clients. In many cases, the trustworthiness of the publishers cannot be...

In the medical field, we are amassing phenomenal amounts of data. This data is imperative in discovering patterns and trends to help improve healthcare. Yet the researchers cannot rejoice as the data cannot be easily shared, because health data custodians have the understandable ethical and legal responsibility to maintain the privacy of individuals. Many techniques of anonymization have been p...
Organizations share their data about customers for exploring potential business avenues. The sharing of data has posed several threats leading to individual identification. Owing to this, privacy preserving data publication has become an important research problem. The main goals of this problem are to preserve privacy of individuals while revealing useful information. An organization may imple...
