Towards an Information Theoretic Metric for Anonymity [chapter]

Andrei Serjantov, George Danezis
2003 Lecture Notes in Computer Science  
We then propose an alternative information theoretic measure of anonymity which takes into account the probabilities of users sending and receiving the messages and show how to calculate it for a message  ...  In this paper we look closely at the popular metric of anonymity, the anonymity set, and point out a number of problems associated with it.  ...  We have also proposed an information-theoretic metric based on the idea of anonymity probability distributions.  ...

2022 Journal of Surveillance, Security and Safety  
We compare the proposed metric with existing information theoretic metrics and their ability to assess risk for various cases of dataset characteristics.  ...  Methods: In this paper, a new information theoretic-based privacy metric (ITPR) for assessing both the re-identification risk and sensitive information inference risk of datasets is proposed.  ...  Information theoretic risk metrics provide the ability to be applied to different anonymity systems [19] .  ...

Discussing Anonymity Metrics for Mix Based Anonymity Approaches [chapter]

Dang Vinh Pham, Joss Wright
2009 IFIP Advances in Information and Communication Technology  
It is therefore important to find an appropriate measure for the anonymity provided by these approaches.  ...  Today the Chaumian Mix idea is not only an academic approach for anonymous communication, it is also a practical system with many variants used in real-world scenarios.  ...  Extensions of Information Theoretic Metrics There have been a number of attempts to extend the applicability of the basic information theoretic entropy-based metrics of anonymity.  ...

Optimizing the design parameters of threshold pool mixes for anonymity and delay

David Rebollo-Monedero, Javier Parra-Arnau, Jordi Forné, Claudia Diaz
2014 Computer Networks  
Our extensive theoretical analysis finds the optimal mix parametrization and characterizes the optimal trade-off between the contrasting aspects of anonymity and delay, for two information-theoretic measures  ...  Experimental results show that mix optimization may lead to substantial delay reductions for a desirable level of anonymity.  ...  Acknowledgments We would like to thank the anonymous referees for their extremely valuable comments. This work was partly supported by the Spanish Government through projects  ...

The Role of Information Theory in the Field of Big Data Privacy

Mariam Haroutunian, Institute for Informatics and Automation Problems of NAS RA, Karen Mastoyan, Gavar State University

Toward an analytical approach to anonymous wireless networking

Parv Venkitasubramaniam, Ting He, Lang Tong, Stephen Wicker
2008 IEEE Communications Magazine  
AN INFORMATION THEORETIC MEASURE OF ANONYMITY The first step toward an analytical model for this problem is to define a quantifiable measure of anonymity.  ...  In particular, an analytical measure for route anonymity is proposed using information theoretic equivocation.  ...

A three-dimensional approach towards measuring sender anonymity

Neeraj Jaggi, Umesh MarappaReddy, Rajiv Bagai
2011 2011 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)  
We provide justification for three distinct aspects of anonymity, important from the perspectives of a user, a system designer, and an attacker, leading to a three-dimensional approach towards measuring  ...  Finally, we apply the proposed metric to an existing anonymous system and discuss the insights gained.  ...  Information theoretic measures towards quantifying the degree of anonymity are discussed in [13] , [10] .  ...
