Releasing Differentially Private Trajectories with Optimized Data Utility

Bing Li, Hong Zhu, Meiyi Xie
2022 Applied Sciences  
The ubiquity of GPS-enabled devices has resulted in an abundance of data about individual trajectories.  ...  However, existing works are primarily concerned with maintaining the trajectory data geographic utility and neglect the semantic utility.  ...  Acknowledgments: The authors would like to acknowledge the efforts made by the editors and the reviewers, which greatly improved the quality of the paper.  ...

Data tainting and obfuscation: Improving plausibility of incorrect taint

Sandrine Blazy, Stephanie Riaud, Thomas Sirvent
2015 2015 IEEE 15th International Working Conference on Source Code Analysis and Manipulation (SCAM)  
Code obfuscation is designed to impede the reverse engineering of a binary software. Dynamic data tainting is an analysis technique used to identify dependencies between data in a software.  ...  In this paper, we present a code transformation technique meant to prevent the identification of useless results: a few lines of code are inserted in the obfuscated software, so that the results obtained  ...  They should be placed closely before points where the taint is spread from a single data to multiple data.  ...

Malware detection with quantitative data flow graphs

Tobias Wüchner, Martín Ochoa, Alexander Pretschner
2014 Proceedings of the 9th ACM symposium on Information, computer and communications security - ASIA CCS '14  
We base our data flow analysis on the incremental construction of aggregated quantitative data flow graphs.  ...  We demonstrate the feasibility of our approach through a prototypical instantiation and implementation for the Windows operating system.  ...  Second, approaches of the cited kind are typically sensitive to advanced behavioral obfuscation techniques like reordering system calls, randomly inserting bogus calls, or substituting calls with semantically  ...

Context-driven Granular Disclosure Control for Internet of Things Applications

Arezou Soltani Panah, Ali Yavari, Ron van Schyndel, Dimitrios Georgakopoulos, Xun Yi
2017 IEEE Transactions on Big Data  
One such technique is called data obfuscation in which data is deliberately modified to blur the sensitive information, while preserving the data utility.  ...  The current obfuscation techniques, however, focus on the privacy of published datasets shared with untrusted parties.  ...  At the time of data dissemination, the obfuscator masks the sensitive data based on contextual information.  ...

Obfuscating the Topical Intention in Enterprise Text Search

Hwee Hwa Pang, Xiaokui Xiao, Jialie Shen
2012 2012 IEEE 28th International Conference on Data Engineering  
The text search queries in an enterprise can reveal the users' topic of interest, and in turn confidential staff or business information.  ...  To safeguard the enterprise from consequences arising from a disclosure of the query traces, it is desirable to obfuscate the true user intention from the search engine, without requiring it to be re-engineered  ...  ACKNOWLEDGEMENT We thank the reviewers for their constructive feedback. HweeHwa Pang is supported by Research Grant 10-C220-SMU-003 from the Singapore Management University.  ...

Dialing Privacy and Utility: A Proposed Data-Sharing Framework to Advance Internet Research

Erin E Kenneally, Kimberly Claffy
2010 IEEE Security and Privacy  
Anonymized data may not immediately expose PII, but any time a piece of de-identified data has been linked to first order identifying information, other anonymous aspects of the obfuscated data are easier  ...  Prominent privacy-sensitive techniques include: A. Deleting/filtering sensitive data. B. Deleting/filtering part(s) of the sensitive data. C.  ...

Information Security in Big Data: Privacy and Data Mining

Lei Xu, Chunxiao Jiang, Jian Wang, Jian Yuan, Yong Ren
2014 IEEE Access  
The growing popularity and development of data mining technologies bring serious threat to the security of individual's sensitive information.  ...  The basic idea of PPDM is to modify the data in such a way so as to perform data mining algorithms effectively without compromising the security of sensitive information contained in the data.  ...  [44] group nodes in the underlying map to create obfuscation areas around sensitive locations. The sensitive nodes on the map are pre-specified by the data owner.  ...
