Privacy Preference Signals: Past, Present and Future
Authors: Hils Maximilian , Woods Daniel W. , Böhme Rainer 
Published: July 2021

Abstract
Privacy preference signals are digital representations of how users want their personal data to be processed. Such signals must be adopted by both the sender (users) and intended recipients (data processors). Adoption represents a coordination problem that remains unsolved despite efforts dating back to the 1990s. Browsers implemented standards like the Platform for Privacy Preferences (P3P) and Do Not Track (DNT), but vendors profiting from personal data faced few incentives to receive and respect the expressed wishes of data subjects. In the wake of recent privacy laws, a coalition of AdTech firms published the Transparency and Consent Framework (TCF), which defines an optin consent signal. This paper integrates post-GDPR developments into the wider history of privacy preference signals. Our main contribution is a high-frequency longitudinal study describing how TCF signal gained dominance as of February 2021. We explore which factors correlate with adoption at the website level. Both the number of third parties on a website and the presence of Google Ads are associated with higher adoption of TCF. Further, we show that vendors acted as early adopters of TCF 2.0 and provide two case-studies describing how Consent Management Providers shifted existing customers to TCF 2.0. We sketch ways forward for a pro-privacy signal.
SwapCT: Swap Confidential Transactions for Privacy-Preserving Multi-Token Exchanges

Published: July 2021

Abstract
Decentralized token exchanges allow for secure trading of tokens without a trusted third party. However, decentralization is mostly achieved at the expense of transaction privacy. For a fair exchange, transactions must remain private to hide the participants and volumes while maintaining the possibility for noninteractive execution of trades. In this paper we present a swap confidential transaction system (SwapCT) which is related to ring confidential transactions (e.g. used in Monero) but supports multiple token types to trade among and enables secure, partial transactions for noninteractive swaps. We prove that SwapCT is secure in a strict, formal model and present its efficient performance in a prototype implementation with logarithmic signature sizes for large anonymity sets. For our construction we design an aggregatable signature scheme which might be of independent interest. Our SwapCT system thereby enables a secure and private exchange for tokens without a trusted third party.
Fortified Multi-Party Computation: Taking Advantage of Simple Secure Hardware Modules

Abstract
In practice, there are numerous settings where mutually distrusting parties need to perform distributed computations on their private inputs. For instance, participants in a first-price sealed-bid online auction do not want their bids to be disclosed. This problem can be addressed using secure multi-party computation (MPC), where parties can evaluate a publicly known function on their private inputs by executing a specific protocol that only reveals the correct output, but nothing else about the private inputs. Such distributed computations performed over the Internet are susceptible to remote hacks that may take place during the computation. As a consequence, sensitive data such as private bids may leak. All existing MPC protocols do not provide any protection against the consequences of such remote hacks. We present the first MPC protocols that protect the remotely hacked parties’ inputs and outputs from leaking. More specifically, unless the remote hack takes place before the party received its input or all parties are corrupted, a hacker is unable to learn the parties’ inputs and outputs, and is also unable to modify them. We achieve these strong (privacy) guarantees by utilizing the fact that in practice parties may not be susceptible to remote attacks at every point in time, but only while they are online, i.e. able to receive messages. To this end, we model communication via explicit channels. In particular, we introduce channels with an airgap switch (disconnect-able by the party in control of the switch), and unidirectional data diodes. These channels and their isolation properties, together with very few, similarly simple and plausibly remotely unhackable hardware modules serve as the main ingredient for attaining such strong security guarantees. In order to formalize these strong guarantees, we propose the UC with Fortified Security (UC#) framework, a variant of the Universal Composability (UC) framework.
Secure integer division with a private divisor
Authors: Veugen Thijs , Abspoel Mark 
Published: July 2021

Abstract
We consider secure integer division within a secret-sharing based secure multi-party computation framework, where the dividend is secret-shared, but the divisor is privately known to a single party. We mention various applications where this situation arises. We give a solution within the passive security model, and extend this to the active model, achieving a complexity linear in the input bit length. We benchmark both solutions using the well-known MP-SPDZ framework in a cloud environment. Our integer division protocol with a private divisor clearly outperforms the secret divisor solution, both in runtime and communication complexity.
Blocking Without Breaking: Identification and Mitigation of Non-Essential IoT Traffic

Published: July 2021

Abstract
Despite the prevalence of Internet of Things (IoT) devices, there is little information about the purpose and risks of the Internet traffic these devices generate, and consumers have limited options for controlling those risks. A key open question is whether one can mitigate these risks by automatically blocking some of the Internet connections from IoT devices, without rendering the devices inoperable.
In this paper, we address this question by developing a rigorous methodology that relies on automated IoT-device experimentation to reveal which network connections (and the information they expose) are essential, and which are not. We further develop strategies to automatically classify network traffic destinations as either required (i.e., their traffic is essential for devices to work properly) or not, hence allowing firewall rules to block traffic sent to non-required destinations without breaking the functionality of the device. We find that indeed 16 among the 31 devices we tested have at least one blockable non-required destination, with the maximum number of blockable destinations for a device being 11. We further analyze the destination of network traffic and find that all third parties observed in our experiments are blockable, while first and support parties are neither uniformly required or non-required. Finally, we demonstrate the limitations of existing blocklists on IoT traffic, propose a set of guidelines for automatically limiting non-essential IoT traffic, and we develop a prototype system that implements these guidelines.
Residue-Free Computing
Authors: Arkema Logan , Sherr Micah 
Published: July 2021

Abstract
Computer applications often leave traces or residues that enable forensic examiners to gain a detailed understanding of the actions a user performed on a computer. Such digital breadcrumbs are left by a large variety of applications, potentially (and indeed likely) unbeknownst to their users. This paper presents the concept of residue-free computing in which a user can operate any existing application installed on their computer in a mode that prevents trace data from being recorded to disk, thus frustrating the forensic process and enabling more privacy-preserving computing. In essence, residue-free computing provides an “incognito mode” for any application. We introduce our implementation of residue-free computing, ResidueFree, and motivate ResidueFree by inventorying the potentially sensitive and privacy-invasive residue left by popular applications. We demonstrate that ResidueFree allows users to operate these applications without leaving trace data, while incurring modest performance overheads.
Differentially Private Naïve Bayes Classifier Using Smooth Sensitivity
Authors: Zafarani Farzad , Clifton Chris 
Published: July 2021

Abstract
There is increasing awareness of the need to protect individual privacy in the training data used to develop machine learning models. Differential Privacy is a strong concept of protecting individuals. Naïve Bayes is a popular machine learning algorithm, used as a baseline for many tasks. In this work, we have provided a differentially private Naïve Bayes classifier that adds noise proportional to the smooth sensitivity of its parameters. We compare our results to Vaidya, Shafiq, Basu, and Hong [1] which scales noise to the global sensitivity of the parameters. Our experimental results on real-world datasets show that smooth sensitivity significantly improves accuracy while still guaranteeing ɛ-differential privacy.
Gage MPC: Bypassing Residual Function Leakage for Non-Interactive MPC

Abstract
Existing models for non-interactive MPC cannot provide full privacy for inputs, because they inherently leak the residual function (i.e., the output of the function on the honest parties’ input together with all possible values of the adversarial inputs). For example, in any non-interactive sealed-bid auction, the last bidder can figure out what was the highest previous bid. We present a new MPC model which avoids this privacy leak. To achieve this, we utilize a blockchain in a novel way, incorporating smart contracts and arbitrary parties that can be incentivized to perform computation (“bounty hunters,” akin to miners). Security is maintained under a monetary assumption about the parties: an honest party can temporarily supply a recoverable collateral of value higher than the computational cost an adversary can expend. We thus construct non-interactive MPC protocols with strong security guarantees (full security, no residual leakage) in the short term. Over time, as the adversary can invest more and more computational resources, the security guarantee decays. Thus, our model, which we call Gage MPC, is suitable for secure computation with limited-time secrecy, such as auctions. A key ingredient in our protocols is a primitive we call “Gage Time Capsules” (GaTC): a time capsule that allows a party to commit to a value that others are able to reveal but only at a designated computational cost. A GaTC allows a party to commit to a value together with a monetary collateral. If the original party properly opens the GaTC, it can recover the collateral. Otherwise, the collateral is used to incentivize bounty hunters to open the GaTC. This primitive is used to ensure completion of Gage MPC protocols on the desired inputs. As a requisite tool (of independent interest), we present a generalization of garbled circuit that are more robust: they can tolerate exposure of extra input labels. This is in contrast to Yao’s garbled circuits, whose secrecy breaks down if even a single extra label is exposed. Finally, we present a proof-of-concept implementation of a special case of our construction, yielding an auction functionality over an Ethereum-like blockchain.
Privacy-Preserving Approximate k-Nearest-Neighbors Search that Hides Access, Query and Volume Patterns
Authors: Boldyreva Alexandra , Tang Tianxin 
Published: July 2021

Abstract
We study the problem of privacy-preserving approximate kNN search in an outsourced environment — the client sends the encrypted data to an untrusted server and later can perform secure approximate kNN search and updates. We design a security model and propose a generic construction based on locality-sensitive hashing, symmetric encryption, and an oblivious map. The construction provides very strong security guarantees, not only hiding the information about the data, but also the access, query, and volume patterns. We implement, evaluate efficiency, and compare the performance of two concrete schemes based on an oblivious AVL tree and an oblivious BSkiplist.

Perkembangan teknologi beton membuat ikut berkembangnya struktur beton bertulang. Salah satunya adalah struktur drop panel. Drop panel merupakan struktur pengganti balok yang diproyeksikan dibawah flat slab dengan penambahan ketebalan pada kepala kolomnya. Namun, peraturan-paraturan yang menjelaskan tentang struktur ini masih sedikit, sehingga SNI 2847 : 2013 dan SNI 1726 : 2012 memberi batasan pada struktur drop panel dan flat slab hanya dapat digunakan pada struktur rangka pemikul momen menengah dan digunakan pada wilayah gempa ringan atau sedang. Jogja Apartemen termasuk ke dalam struktur rangka pemikul momen khusus dan berada pada wilayah gempa tinggi. Oleh karena itu dilakukan penelitian dengan mendesain ulang struktur drop panel Jogja Apartemen digantikan dengan balok konvensional untuk mendapatkan tingkat keamanan struktur terhadap parameter-parameter beban gempa, persyaratan beton bertulang, perbandingan dimensi awal drop panel, balok, dan flat slab dengan desain baru dan memperoleh perbandingan rasio volume beton bertulang. Penelitian ini dilakukan dengan merubah perencanaan drop panel dan balok awal dengan balok baru tanpa drop panel yang dibantu dengan software analisis numerik ETABS. Dari hasil penelitian didapat bahwa desain denah balok baru tanpa drop panel dinyatakan aman terhadap parameter-parameter beban gempa berupa periode getar struktur dengan nilai arah x dan y di bawah batas maksimum sebesar 2,03 detik, base shear dimana V dinamik lebih besar dari 85 % V statik , perpindahan maksimum arah x dan y di bawah batas limit, stabilitas rasio pengaruh P-delta kurang dari nilai maksimum sebesar 0,091, faktor pembesaran torsi kurang dari 3, dan mengalami penurunan volume beton sebesar 16,27 % dengan rasio tulangan mengalami penurunan sebesar 12,62 %.

Gerakan 5R (Ringkas, Rapi, Resik, Rawat, Rajin) di PT X sangat berkaitan erat dengan K3 (Keselamatan dan Kesehatan Kerja) yang sesuai dengan standar OHSAS 18001 (Occupational Health and Safety Assessment Series). Guna mengetahui sejauhmana pengaruhnya terhadap karyawan maka dilakukan analisis penerapan program K3/5R di PT X dengan pendekatan standar OHASAS 18001 dan statistik tes U Mann-Whitney serta pengaruhnya pada produktivitas karyawan, dan kemungkinan penerapan pada proyek konstruksi sesuai Instruksi Menteri PUPR No. 02/IN/M/2020 tentang Protokol Pencegahan Penyebaran COVID-19. Dari hasil analisis produktivitas kerja ternyata setelah penerapan 5R ada pengaruhnya, terlihat dari tes U Mann-Whitney dengan H0 ditolak dan H1 diterima. Dengan demikian pengaruh penerapan 5R cukup besar. Pada saat dimulainya Gerakan 5R terlihat bahwa produktivitas kerja karyawan naik cukup besar dari Rp. 5,93 juta/karyawan pada tahun ke 6 (Tahun pertama dimulai Gerakan 5) menjadi 10,98 pada tahun ke 7 (Tahun kedua Gerakan 5R) atau naik 85,2%. Demikian pula pada tahun ke 8 (Tahun ketiga Gerakan 5R) produktivitas kerja menjadi 20,59 atau naik 87,5% dibandingkan dengan produktivitas kerja tahun ke 7 (Tahun kedua Gerakan 5R).
