Multi-resolution privacy-enhancing technologies for smart metering

Fabian Knirsch, Günther Eibl, Dominik Engel
2017 EURASIP Journal on Information Security  
For three types of privacy methods (secure aggregation, masking and differential privacy), we show that MRA not only enhances privacy, but also adds additional flexibility and control for the end-user.  ...  The combination of MRA and PETs is evaluated in terms of privacy, computational demands, and real-world feasibility for each of the three method types.  ...  Acknowledgements The financial support by the Austrian Federal Ministry of Science, Research and Economy and the Austrian National Foundation for Research, Technology and Development is gratefully acknowledged  ...

Lifted Relational Neural Networks [article]

Gustav Sourek, Vojtech Aschenbrenner, Filip Zelezny, Ondrej Kuzelka
2015 arXiv   pre-print
A general lifted architecture, possibly reflecting some background domain knowledge, is described through relational rules which may be handcrafted or learned.  ...  The framework allows for hierarchical relational modeling constructs and learning of latent relational concepts through shared hidden layers weights corresponding to the rules.  ...  Acknowledgments GS and FŽ are supported by Cisco sponsored research project "Modelling network traffic with relational features".  ...

Higher-order probabilistic adversarial computations: Categorical semantics and program logics [article]

Alejandro Aguirre, Gilles Barthe, Marco Gaboardi, Deepak Garg, Shin-ya Katsumata, Tetsuya Sato
2021 arXiv   pre-print
We prove the soundness of the logics in the category of quasi-Borel spaces, using a general notion of graded predicate liftings, and we use logical relations over graded predicate liftings to establish  ...  We develop unary program logics for reasoning about error probabilities and expected values, and a relational logic for reasoning about coupling-based properties.  ...  We introduce the concept of Heyting-algebra valued strong graded relational lifting. 93:25 Example 6.6 (Relational lifting for differential privacy).  ...

Generalised Differential Privacy for Text Document Processing [article]

Natasha Fernandes, Mark Dras, Annabelle McIver
2019 arXiv   pre-print
In this paper we combine ideas from "generalised differential privacy" and machine learning techniques for text processing to model privacy for text documents.  ...  We show that our mechanism satisfies privacy with respect to a metric for semantic similarity, thereby providing a balance between utility, defined by the semantic content of texts, with the obfuscation  ...  [12] for lifting a differentially private mechanism K: X → DX to a differentially private mechanism K : X N → DX N on vectors in X N .  ...

Specificities, Obstacles and Limits to Building Customer Loyalty in Mountain Resort Luxury Hotels

Maud Tixier
2011 Modern Economy  
We shall base our findings on the example of Courchevel, located in the Savoie region, in France, a resort renowned worldwide for its concentration of luxury and 5-star hotels with their star-winning chefs  ...  Fifty or so qualitative interviews on the topic of customer loyalty were carried out in twenty or so hotels for this study between 2008 and 2010.  ...  Meeting these expectations is the priority for any luxury hotel and will have more or less impact according to their discriminatory and differentiating character compared to the competition.  ...
