Differential privacy with δ-neighbourhood for spatial and dynamic datasets
2014
Proceedings of the 9th ACM symposium on Information, computer and communications security - ASIA CCS '14
Preserved Fulltext
Differential privacy provides a strong guarantee in protecting privacy of individuals who contributed to a published dataset. ...
For dynamic datasets, while there are known negative results on the standard differential privacy, it is possible to continuously and indefinitely publish under δ-neighbourhood by reusing the privacy budgets ...
PUBLISHING SPATIAL DATASET Although an -differentially private mechanism under the standard neighbourhood is also -differentially private under δ-neighbourhood, it may not achieve our intention of investing ...

We consider the problem of publishing location datasets, in particular 2D spatial pointsets, in a differentially private manner. ...
The publishing process is simple from the publisher's point of view: the publisher just needs to map the data, sort them, group them, add Laplace noise and publish the dataset. ...
Note that a mechanism that achieves differential privacy under replacement neighborhood can be converted to one that achieves privacy under the welladopted neighborhood. ...

Consequently, we are able to place different privacy models including differential privacy and early syntactic models on the same scale, and compare their privacy/utility tradeoff. ...
Early models (kanonymity and -diversity) are now thought to offer insufficient privacy. Noise-based methods like differential privacy are seen as providing stronger privacy, but less utility. ...
In this region either -diversity or t-closeness can outperform differential privacy under these metrics as shown in both plots. ...
