Investigating People’s Privacy Risk Perception
Authors: Gerber Nina , Reinheimer Benjamin , Volkamer Melanie 
Published: July 2019

Abstract
Although media reports often warn about risks associated with using privacy-threatening technologies, most lay users lack awareness of particular adverse consequences that could result from this usage. Since this might lead them to underestimate the risks of data collection, we investigate how lay users perceive different abstract and specific privacy risks. To this end, we conducted a survey with 942 participants in which we asked them to rate nine different privacy risk scenarios in terms of probability and severity. The survey included abstract risk scenarios as well as specific risk scenarios, which describe specifically how collected data can be abused, e.g., to stalk someone or to plan burglaries. To gain broad insights into people’s risk perception, we considered three use cases: Online Social Networks (OSN), smart home, and smart health devices. Our results suggest that abstract and specific risk scenarios are perceived differently, with abstract risk scenarios being evaluated as likely, but only moderately severe, whereas specific risk scenarios are considered to be rather severe, but only moderately likely. People, thus, do not seem to be aware of specific privacy risks when confronted with an abstract risk scenario. Hence, privacy researchers or activists should make people aware of what collected and analyzed data can be used for when abused (by the service or even an unauthorized third party).

Abstract
Hypothesis testing is one of the most common types of data analysis and forms the backbone of scientific research in many disciplines. Analysis of variance (ANOVA) in particular is used to detect dependence between a categorical and a numerical variable. Here we show how one can carry out this hypothesis test under the restrictions of differential privacy. We show that the F -statistic, the optimal test statistic in the public setting, is no longer optimal in the private setting, and we develop a new test statistic F
1 with much higher statistical power. We show how to rigorously compute a reference distribution for the F
1 statistic and give an algorithm that outputs accurate p-values. We implement our test and experimentally optimize several parameters. We then compare our test to the only previous work on private ANOVA testing, using the same effect size as that work. We see an order of magnitude improvement, with our test requiring only 7% as much data to detect the effect.
ConsenSGX: Scaling Anonymous Communications Networks with Trusted Execution Environments
Authors: Sasy Sajin , Goldberg Ian 
Published: July 2019

AbstractAnonymous communications networks enable individuals to maintain their privacy online. The most popular such network is Tor, with about two million daily users; however, Tor is reaching limits of its scalability. One of the main scalability bottlenecks of Tor and similar network designs originates from the requirement of distributing a global view of the servers in the network to all network clients. This requirement is in place to avoidepistemic attacks, in which adversaries who know which parts of the network certain clients do and do not know about can rule in or out those clients from being responsible for particular network traffic.In this work, we introduce a novel solution to this scalability problem by leveraging oblivious RAM constructions and trusted execution environments in order to enable clients to fetch only the parts of the network view they require, without the directory servers learning which parts are being fetched. We compare the performance of our design with the current Tor mechanism and other related works to show one to two orders of magnitude better performance from an end-to-end perspective. We analyse the requirements to actually deploy such a scheme today and conclude that it would only require a small fraction (<2.5%) of the relays to have the required hardware support; moreover, these relays can perform their roles with minimal network bandwidth requirements.
Circumventing Cryptographic Deniability with Remote Attestation
Authors: Gunn Lachlan J. , Parra Ricardo Vieitez , Asokan N. 
Published: July 2019

Abstract
Deniable messaging protocols allow two parties to have ‘off-the-record’ conversations without leaving any record that can convince external verifiers about what either of them said during the conversation. Recent events like the Podesta email dump underscore the importance of deniable messaging to politicians, whistleblowers, dissidents and many others. Consequently, messaging protocols like Signal and OTR are designed with cryptographic mechanisms to ensure deniable communication, irrespective of whether the communications partner is trusted.
Many commodity devices today support hardware-assisted remote attestation which can be used to convince a remote verifier of some property locally observed on the device.
We show how an adversary can use remote attestation to undetectably generate a non-repudiable transcript from any deniable protocol (including messaging protocols) providing sender authentication, proving to skeptical verifiers what was said. We describe a concrete implementation of the technique using the Signal messaging protocol. We then show how to design protocols that are deniable even against an adversary capable of attestation, and in particular how attestation itself can be used to restore deniability by thwarting realistic classes of adversary.
Git Blame Who?: Stylistic Authorship Attribution of Small, Incomplete Source Code Fragments
Authors: Dauber Edwin , Caliskan Aylin , Harang Richard , Shearer Gregory , Weisman Michael , Nelson Frederica , Greenstadt Rachel 
Published: July 2019

Abstract
Program authorship attribution has implications for the privacy of programmers who wish to contribute code anonymously. While previous work has shown that individually authored complete files can be attributed, these efforts have focused on such ideal data sets as contest submissions and student assignments. We explore the problem of authorship attribution “in the wild,” examining source code obtained from open-source version control systems, and investigate how contributions can be attributed to their authors, either on an individual or a per-account basis. In this work, we present a study of attribution of code collected from collaborative environments and identify factors which make attribution of code fragments more or less successful. For individual contributions, we show that previous methods (adapted to be applied to short code fragments) yield an accuracy of approximately 50% or 60%, depending on whether we average by sample or by author, at identifying the correct author out of a set of 104 programmers. By ensembling the classification probabilities of a sufficiently large set of samples belonging to the same author we achieve much higher accuracy for assigning the set of samples to the correct author from a known suspect set. Additionally, we propose the use of calibration curves to identify which samples are by unknown and previously unencountered authors.

Published: July 2019

Abstract

Background
Chronic rhinosinusitis (CRS) current therapeutic approaches still fail in some patients with severe persistent symptoms and recurrences after surgery. We aimed to evaluate the master transcription factors gene expression levels of T cell subtypes in chronic rhinosinusitis with nasal polyps (CRSwNP) and chronic rhinosinusitis without nasal polyps (CRSsNP) that could represent new, up-stream targets for topical DNAzyme treatment.

Patients and methods
Twenty-two newly diagnosed CRS patients (14 CRSwNP and 8 CRSsNP) were prospectively biopsied and examined histopathologically. Gene expression levels of T-box transcription factor (T-bet, TBX21), GATA binding protein 3 (GATA3), Retinoic acid-related orphan receptor C (RORC) and Forkhead box P3 (FOXP3) were analyzed by real-time quantitative polymerase chain reaction (RT-qPCR).

Results
Eosinophilic CRSwNP was characterized by higher level of GATA3 gene expression compared to noneosinophilic CRSwNP, whereas there was no difference in T-bet, RORC and FOXP3 between eosinophilic and noneosinophilic CRSwNP. In CRSsNP, we found simultaneous upregulation of T-bet, GATA3 and RORC gene expression levels in comparison to CRSwNP; meanwhile, there was no difference in FOXP3 gene expression between CRSwNP and CRSsNP.

Conclusions
In eosinophilic CRSwNP, we confirmed the type 2 inflammation by elevated GATA3 gene expression level. In CRSsNP, we unexpectedly found simultaneous upregulation of T-bet and GATA3 that is currently unexplained; however, it might originate from activated CD8+ cells, abundant in nasal mucosa of CRSsNP patients. The elevated RORC in CRSsNP could be part of homeostatic nasal immune response that might be better preserved in CRSsNP patients compared to CRSwNP patients. Further data on transcription factors expression rates in CRS phenotypes are needed.

Published: July 2019

Abstract
Maximum utilization of lignocellulosic biomass is contingent upon degrading the recalcitrant lignin polymer. Conventional methods employed in delignification require high inputs of energy and chemicals, resulting in the release of highly toxic effluents. The ability of gut flora of Coptotermes curvignathus in lignin degradation was investigated in this study. Production of ligninolytic enzymes was done in an aerated submerged fermentation system with kraft lignin as sole carbon source. The degradation experiment was carried out for 7 days at 30 °C, pH 7. Three potential lignin degraders identified as Bacillus sp., Lysinibacillus sp. and Acinetobacter sp. were successfully isolated. The bacterial growth and secretion of extracellular ligninolytic enzymes confirmed metabolism of kraft lignin by the identified strains. Lysinibacillus sp., a novel lignin degrader showed highest manganese peroxidase (76.36 ± 15.74 U/L) and laccase activity (70.67 ± 16.82 U/L) after 7 and 6 days of incubation respectively, while maximal activity of lignin peroxidase (262.49 ± 0.92 U/L) was recorded after 7 days in culture supernatants of Bacillus sp. With respect to the activity of the secreted enzymes, the lignin degrading potential of these bacterial strains can be explored in the valorisations of lignocellulosic biomass in industrial processes such as pulping, bioethanol production, fine chemicals and materials synthesis.

ANALISIS LUASNYA PENGUNGKAPAN KUANTITATIF PADA INTEGRATED REPORTING DI INDONESIA, MALAYSIA, DAN SINGAPURA
Authors: Febriyanti Agnes Febriyanti , Gunawan Juniati 
Published: July 2019

This study aims to determine how much disclosures can be found on the IR issued by companies in Indonesia, Malaysia, and Singapore that implement International <IR> Framework as a guide. This study uses a total observation of 21 (twenty one) Integrated Reports, consisting of 12 (twelve) IR from Indonesia, 5 (five) IR from Malaysia, and 4 (four) IR from Singapore, where the entire population is used as the research object.Content analysis and descriptive qualitative are used as the chosen methods to explore many information disclosures. The result of this study shows that IR in Indonesia, Malaysia, and Singapore falls in the high category. This achievement was obtained because the companies that are used as the object of the research (the companies that publish IR) might be are top companies (total assets, capital, business lines, and employees) and have a good reputation. In addition, the companies that are used as a sample of this research have reported a sustainability report in the previous period which has an indicator similar to IR.Additionally, this study shows that IR in Indonesia is leading in reporting risks and opportunities because regulators require public companies have a risk management committee (Regulation of Bapepam and LK X.K.6). Whereas, IR in Malaysia and Singapore are leading in basic preparation and presentation of IR in behalf of the guidance of the current corporate reporting (Sustainability Reporting Guide - Malaysia and Singapore Stock Exchange) that has similar indicators to the International <IR> Framework. However, the third IR lacks the ability to disclose the strategy and allocation of resources are caused by uncertainty. The trend for subsequent reporting will be done through IR, IR is considered capable of creating organization’s value in the short, medium, and long term to meet the needs of stakeholders.
