Extended K-Anonymity Model for Privacy Preserving on Micro Data

Masoud Rahimi, Mehdi Bateni, Hosein Mohammadinejad
2015 International Journal of Computer Network and Information Security  
In order to overcome this problem, several approaches, called p-sensitive k-anonymity, p+-sensitive k-anonymity, and (p, α)-sensitive k-anonymity, were proposed.  ...  The drawbacks of these methods include the inability to protect micro datasets against attribute disclosure and the high value of the distortion ratio.  ...  A.3 -The Distortion Ratio: the distortion ratio of four privacy preservation measures were compared: psensitive k-anonymity, p+-sensitive k-anonymity, (p, α)sensitive k-anonymity, (k, p, t) Anonymizing3Layer  ...

Improving data utility in differential privacy and k-anonymity [article]

Jordi Soria-Comas
2013 arXiv   pre-print
We focus on two mainstream privacy models: k-anonymity and differential privacy. Once a privacy model has been selected, the goal is to enforce it while preserving as much data utility as possible.  ...  On the data utility side, dealing with a large number of quasi-identifier attributes is problematic. We propose a relaxation of k-anonymity that deals with these issues.  ...  Probabilistic k-anonymity We propose a privacy model that, similarly to k-anonymity, protects against identity disclosure (the probability of determining the true identity for a specific value of a confidential  ...

k-Anonymization in the Presence of Publisher Preferences

Rinku Dewri, Indrajit Ray, Indrakshi Ray, Darrell Whitley
2011 IEEE Transactions on Knowledge and Data Engineering  
Existing methods for this purpose modify the data only to the extent necessary to satisfy the privacy constraints, thereby asserting that the information loss has been minimized.  ...  Privacy constraints are typically enforced on shared data that contain sensitive personal attributes.  ...  This check must be appropriately modified when considering a privacy model different from k-anonymity.  ...

Then IKA is further categorized into Improved Symmetric k-Anonymization (ISKA) and Improved Asymmetric k-Anonymization (IAKA). After anonymizing data using IKA, ILD model is used to increase privacy.  ...  In order to maintain privacy, different methods of k-anonymization and l-diversity have been widely used. But for larger datasets, the results are not very promising.  ...  Acknowledgement We are grateful to the Madhya Pradesh State Election Commission, India, for their enthusiastic and constant support and for providing us with the real-time big dataset needed for the research  ...
