Pattern-Guided k-Anonymity [PDF]

open access: yesAlgorithms, 2013
We suggest a user-oriented approach to combinatorial data anonymization. A data matrix is called k-anonymous if every row appears at least k times—the goal of the NP-hard k-ANONYMITY problem then is to make a given matrix k-anonymous by suppressing ...

Daily activity locations k-anonymity for the evaluation of disclosure risk of individual GPS datasets [PDF]

open access: yesInternational Journal of Health Geographics, 2020
Background Personal privacy is a significant concern in the era of big data. In the field of health geography, personal health data are collected with geographic location information which may increase disclosure risk and threaten personal geoprivacy ...

MultiRelational k-Anonymity [PDF]

open access: yes2007 IEEE 23rd International Conference on Data Engineering, 2007
k-anonymity protects privacy by ensuring that data cannot be linked to a single individual. In a k-anonymous dataset, any identifying information occurs in at least k tuples. Much research has been done to modify a single table dataset to satisfy anonymity constraints.

k-Same-Net: k-Anonymity with Generative Deep Neural Networks for Face Deidentification [PDF]

open access: yesEntropy, 2018
Image and video data are today being shared between government entities and other relevant stakeholders on a regular basis and require careful handling of the personal information contained therein. A popular approach to ensure privacy protection in such

Location Prediction Based on Transition Probability Matrices Constructing from Sequential Rules for Spatial-Temporal K-Anonymity Dataset. [PDF]

open access: yesPLoS ONE, 2016
Spatial-temporal k-anonymity has become a mainstream approach among techniques for protection of users' privacy in location-based services (LBS) applications, and has been applied to several variants such as LBS snapshot queries and continuous queries ...

Efficient Multidimensional Suppression for K-Anonymity [PDF]

open access: yesIEEE Transactions on Knowledge and Data Engineering, 2010
Many applications that employ data mining techniques involve mining data that include private and sensitive information about the subjects. One way to enable effective data mining while preserving privacy is to anonymize the data set that includes private information about subjects before being released for data mining. One way to anonymize data set is

Optimization-Based k-Anonymity Algorithms

open access: yesComputers & Security, 2020
<p>In this paper we present a formulation of <em>k</em>-anonymity as a mathematical <a href="https://www.sciencedirect.com/topics/computer-science/optimization-problem" target="_blank">optimization problem</a>. In solving this formulated problem, <em>k</em>-anonymity is achieved while maximizing the utility of ...

Location privacy protection method based on lightweight K-anonymity incremental nearest neighbor algorithm

open access: yes网络与信息安全学报, 2023
The use of location-based service brings convenience to people’s daily lives, but it also raises concerns about users’ location privacy.In the k-nearest neighbor query problem, constructing K-anonymizing spatial regions is a method used to protects users’
