Time-Aware Anonymization of Knowledge Graphs

چکیده

Knowledge graphs (KGs) play an essential role in data sharing because they can model both users’ attributes and their relationships. KGs tailor many analyses, such as classification where a sensitive attribute is selected the analyst analyzes associations between users attribute’s values (aka values). Data providers anonymize share anonymized versions to protect privacy. Unfortunately, adversary exploit these relationships infer information by monitoring either one or snapshots of KG. To cope with this issue, paper, we introduce ( k , l )-Sequential Attribute Degree (( )-sad), extension w -tad principle[10], ensure that re-identified are diverse enough prevent them from being inferred confidence higher than \(\frac{1}{l} \) even though adversaries monitor all published KGs. In addition, develop Time-Aware Graph Anonymization Algorithm KG satisfy )-sad principle, by, at same time, preserving utility data. We conduct experiments on four real-life datasets show effectiveness our proposal compare it -tad.

On Anonymization of Multi-graphs

The problem of privacy-preserving data mining has attracted considerable attention in recent years because of increasing concerns about the privacy of the underlying data. In recent years, an important data domain which has emerged is that of graphs and structured data. Many data sets such as XML data, transportation networks, traffic in IP networks, social networks and hierarchically structure...

Pragmatics Aware Querying in Heterogeneous Knowledge Graphs

With the increase in structured Linked Data sources, Knowledge Graphs(KG) are becoming indispensable in areas like Question Answering, Web Search and Data Analytics. Given the richness present in the KG schema definitions, more expressive user querying is possible. However, accessing KGs is still challenging, because the rich schema is not exposed in a more intuitive way to the naive user. This...

Completeness-Aware Rule Learning from Knowledge Graphs

Knowledge graphs (KGs) are huge collections of primarily encyclopedic facts. They are widely used in entity recognition, structured search, question answering, and other important tasks. Rule mining is commonly applied to discover patterns in KGs. However, unlike in traditional association rule mining, KGs provide a setting with a high degree of incompleteness, which may result in the wrong est...

Query-aware location anonymization for road networks

Recently, several techniques have been proposed to protect the user location privacy for location-based services in the Euclidean space. Applying these techniques directly to the road network environment would lead to privacy leakage and inefficient query processing. In this paper, we propose a new location anonymization algorithm that is designed specifically for the road network environment. ...

L-opacity: Linkage-Aware Graph Anonymization

The wealth of information contained in online social networks has created a demand for the publication of such data as graphs. Yet, publication, even after identities have been removed, poses a privacy threat. Past research has suggested ways to publish graph data in a way that prevents the re-identification of nodes. However, even when identities are effectively hidden, an adversary may still ...
