Abstract:

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2005.<br>Vita.<br>Includes bibliographical references (p. 129-142).<br>A content distribution network (CDN) makes a publisher's content highly available to readers through replication on remote computers. Content stored on untrusted servers is susceptible to attack, but a reader should have confidence that content originated from the publisher and that the content is unmodified. This thesis presents the SFS read-only file system (SFSRO) and key regression in the Chefs file system for secure, efficient content distribution using untrusted servers for public and private content respectively. SFSRO ensures integrity, authenticity, and freshness of single-writer, many-reader content. A publisher creates a digitally-signed database representing the contents of a source file system. Untrusted servers replicate the database for high availability. Chefs extends SFSRO with key regression to support decentralized access control of private content protected by encryption. Key regression allows a client to derive past versions of a key, reducing the number of keys a client must fetch from the publisher. Thus, key regression reduces the bandwidth requirements of publisher to make keys available to many clients.<br>(cont.) Contributions of this thesis include the design and implementation of SFSRO and Chefs; a concrete definition of security, provably-secure constructions, and an implementation of key regression; and a performance evaluation of SFSRO and Chefs confirming that latency for individual clients remains low, and a single server can support many simultaneous clients.<br>by Kevin E.

Abstract:

Le besoin du contrôle d'accès au contenu dans les hiérarchies (CACH) apparaît naturellement dans de nombreux contextes, allant des départements gouvernementaux aux jeux interactifs, et de la diffusion multi-niveaux des données au contrôle d'accès dans les bases de données. Tous ces contextes ont un point commun, c'est d'avoir besoin de s'assurer que les différentes entités n'accèdent qu'aux ressources auxquelles elles sont autorisées. Le contrôle d'accès au contenu consiste à effectuer cette dernière tâche. Contrôler l'accès aux ressources est généralement assuré en chiffrant les ressources du système et en donnant les clés utilisées pour le chiffrement de ces ressources aux utilisateurs qui y sont autorisés. La génération et la gestion de telles clés est un besoin crucial pour le déploiement des systèmes de contrôle d'accès au contenu. De plus, les hiérarchies à large échelle avec des membres qui changent leurs droits d'accès fréquemment exigent un passage à l'échelle performant du mécanisme de gestion de clés. Dans le cadre de cette thèse, nous nous focalisons sur la gestion de clés pour le contrôle d'accès au contenu. Nous commençons par donner les briques de base de la gestion de clés pour le CACH. Par la suite, nous étudions les schémas de gestion de clés existants et les classifions en deux catégories, à savoir l'approche des clés dépendantes et l'approche des clés indépendantes. Par ailleurs, nous proposons un modèle générique pour représenter les schémas de l'approche des clés indépendantes et l'utilisons pour définir des bornes inférieures sur les coûts de gestion des clés. Par la suite, nous proposons un nouveau schéma indépendant de gestion de clé et prouvons son optimalité en montrant que ses performances atteignent les bornes inférieures. L'optimalité de ce schéma constitue l'un des apports les plus importants de cette thèse. Ensuite, nous proposons deux nouveaux schémas efficaces de l'approche des clés dépendantes et nous les évaluons par simulations et par une modélisation avec les processus de Markov. Enfin, nous proposons une variante de ces schémas qui permet de définir des compromis pertinents sur les différents critères de performances<br>Lots of applications, ranging from interactive online games to business corporations and government departments, and from multi-layered data streaming to databases access control, require ensuring that its users respect some access control restrictions. Content access control in hierarchies (CACH) consists in ensuring, using cryptographic techniques, that the users access application resources to which they are entitled. Content access control is generally ensured by encrypting the system resources and giving the keys to users having access to them. Generating and managing those keys is a crucial requirement for the deployment of content access control systems. Moreover, large scale hierarchies with highly dynamic users present serious scalability issues for key management. In this thesis, we deal with key management for content access control. We start by defining building blocks of key management for CACH. Then, we study the existing key management solutions and classify them into two categories -namely, the dependent keys and independent keys approaches - and propose a key management framework for each category. We further propose a generic model to represent independent-keys key management schemes and use this model to define lower bounds on the key management overhead. Then, we propose a new independent-keys key management scheme and prove that it is optimal by showing that it reaches the overhead lower bounds. The optimality of this scheme constitutes one of the most important results of our thesis. Thereafter, we propose new efficient dependent-keys key management schemes and evaluate them by simulations and Markov process modelling. At last, we propose a variant of our schemes allowing to define trade-offs on the performance criteria. We show that this variant offers a means to define very interesting overhead trade-offs

Abstract:

Au cours de ces dernières années, de plus en plus d’utilisateurs choisissent de diffuser leurs photos sur des plateformes de partage d’images. Ces plateformes permettent aux utilisateurs de restreindre l’accès aux images à un groupe de personnes, afin de donner un sentiment de confiance aux utilisateurs vis-à-vis de la confidentialité de ces images. Malheureusement, la confidentialité ne peut être garantie sachant que le fournisseur de la plateforme a accès aux contenus de n’importe quelle image publiée sur sa plateforme. En revanche, si les images sont mises en ligne chiffrées, seules les personnes ayant la possibilité de déchiffrer les images, auront accès aux images. Ainsi, la confidentialité peut être assurée. Trois principales spécificités sont à prendre en compte lors du chiffrement d’une image : le schéma de chiffrement doit être effectué en respectant le format de l’image (e.g. format JPEG), garantir l’indistinguabilité (l’adversaire ne doit obtenir de l’information sur le contenu de l’image à partir de l’image chiffrée), et doit être compatible avec les traitements des images spécifiques à la plateforme de partage d’images. L’objectif principal de cette thèse a été de proposer un tel schéma de chiffrement pour les images JPEG. Nous avons d’abord proposé et implémenté un schéma de chiffrement garantissant la conservation de l’image et l’indistinguabilité. Malheureusement, nous avons montré que sur Facebook, Instagram, Weibo et Wechat, notre solution ne permettait de maintenir une qualité d’images suffisante après déchiffrement. Par conséquent, des codes correcteurs ont été ajoutés à notre schéma de chiffrement, afin de maintenir la qualité des images<br>In recent years, more and more users prefer to share their photos through image-sharing platforms. Most of platforms allow users to specify who can access to the images, it may result a feeling of safety and privacy. However, the privacy is not guaranteed, since at least the provider of platforms can clearly know the contents of any published images. According to some existing researches, encrypting images before publishing them, and only the authorised users who can decrypt the encrypted image. In this way, user’s privacy can be protected.There are three challenges when proposing an encryption algorithm for the images published on image-sharing platforms: the algorithm has to preserve image format (e.g. JPEG image) after encryption, the algorithm should be secure (i.e. the adversary cannot get any information of plaintext image from the encrypted image), and the algorithm has to be compatible with basic image processing in each platform. In this thesis, our main goal is to propose an encryption algorithm to protect JPEG image privacy on different image-sharing platforms and overcome the three challenges. We first propose an encryption algorithm which can meet the requirements of the first two points. We then implement this algorithm on several widely-used image-sharing platforms. However, the results show that it cannot recover the plaintext image with a high quality after downloading the image from Facebook, Instagram, Weibo and Wechat. Therefore, we add the correcting mechanism to improve this algorithm, which reduces the losses of image information during uploading the encrypted image on each platform and reconstruct the downloaded images with a high quality

Abstract:

We describe a new file system that provides, at the same time, both name and content based access to files. To make this possible, we introduce the concept of a semantic directory. Every semantic directory has a query associated with it. When a user creates a semantic directory, the file system automatically creates a set of pointers to the files in the file system that satisfy the query associated with the directory. This set of pointers is called the query-result of the directory. To access the files that satisfy the query, users just need to de-reference the appropriate pointers. Users can also create files and sub-directories within semantic directories in the usual way. Hence, users can organize files in a hierarchy and access them by specifying path names, and at the same time, retrieve files by asking queries that describe their content. Our file system also provides facilities for query-refinement and customization. When a user creates a new semantic sub-directory within a semantic directory, the file system ensures that the query-result of the sub-directory is a subset of the query-result of its parent. Hence, users can create a hierarchy of semantic directories to refine their queries. Users can also edit the set of pointers in a semantic directory, and thereby modify its query-result without modifying its query or the files in the file system. In this way, users can customize the results of queries according to their personal tastes, and use customized results to refine queries in the future. Our file system has many other features, including semantic mount-points that allow users to access information in other file systems by content. The file system does not depend on the query language used for content-based access. Hence, it is possible to integrate any content-based access mechanism into our file system.

Abstract:

A common problem in the workplace is sharing digital documents with coworkers. Forsome companies the problem extends to wanting the documentskept internally backedup and controlling which people in the company has rights to read and revise certaindocuments.This paper shows different systems and models for access control, version control,and distribution of the documents that can be used to create asystem that solves theseproblems.One requirement for this system was a user interface where users can upload, down-load and manage access to their documents. Another requirement was a service thathandles version control for the documents, and a way to quickly connect and distributethe documents. The system also needed to be able to handle access control of the ver-sioned documents on document level, referred to as "fine grained access control" in thispaper.These models and systems were evaluated based on aspects of the access control mod-els, version control systems, and distribution systems andprotocols. After evaluating,appropriate selections were made to create a prototype to test the system as a whole.The prototype ended up meeting the goals that Nordicstationset for the project butonly with basic functionality. Functionality for retrieving any version from a docu-ments history, controlling access for the documents at document level, and a simpleweb based user interface for managing the documents.<br>Att enkelt dela dokument med arbetskollegor är något alla företag har ett behov utav.Ofta är dessa dokument interna och skall hållas inom företaget.

Abstract:

This Ph.D. thesis tackles the issue of sill and video object categorization. The objective is to associate semantic labels to 2D objects present in natural images/videos. The principle of the proposed approach consists of exploiting categorized 3D model repositories in order to identify unknown 2D objects based on 2D/3D matching techniques. We propose here an object recognition framework, designed to work for real time applications. The similarity between classified 3D models and unknown 2D content is evaluated with the help of the 2D/3D description. A voting procedure is further employed in order to determine the most probable categories of the 2D object. A representative viewing angle selection strategy and a new contour based descriptor (so-called AH), are proposed. The experimental evaluation proved that, by employing the intelligent selection of views, the number of projections can be decreased significantly (up to 5 times) while obtaining similar performance. The results have also shown the superiority of AH with respect to other state of the art descriptors. An objective evaluation of the intra and inter class variability of the 3D model repositories involved in this work is also proposed, together with a comparative study of the retained indexing approaches . An interactive, scribble-based segmentation approach is also introduced. The proposed method is specifically designed to overcome compression artefacts such as those introduced by JPEG compression. We finally present an indexing/retrieval/classification Web platform, so-called Diana, which integrates the various methodologies employed in this thesis

Abstract:

Using a legally obtained dataset of 34 copyrighted O’Reilly Media books, we apply the DE-COP membership inference attack method to investigate whether OpenAI’s large language models were trained on copyrighted content without consent. Our AUROC scores show that GPT-4o, OpenAI’s more recent and capable model, demonstrates strong recognition of paywalled O’Reilly book content (AUROC = 82%), compared to OpenAI’s earlier model GPT-3.5 Turbo. In contrast, GPT-3.5 Turbo shows greater relative recognition of publicly accessible O’Reilly book samples. GPT-4o Mini, as a much smaller model, shows no knowledge of public or non-public O’Reilly Media content when tested (AUROC ≈ 0.5). Testing multiple models, with the same cutoff date, helps us account for potential language shifts over time that might bias our findings. These results highlight the urgent need for increased corporate transparency regarding pre-training data sources as a means to develop formal licensing frameworks for AI content training.

Abstract:

In 2020, ARL’s Advocacy and Public Policy Committee launched a digital rights initiative focused on understanding and safeguarding the full stack of research libraries’ rights: to acquire and lend digital content to fulfill libraries’ functions in research, teaching, and learning; to provide accessible works to people with print disabilities; and to fulfill libraries’ collective preservation function for enduring access to scholarly and cultural works. Our objective is to make sure that these rights are well understood by research libraries, by Congress, by the US Copyright Office, and by the courts. This report discusses licenses and contracts for digital content in the context of the US Copyright Act. The report presents advocacy and public policy strategies, such as rights-saving clauses, open access, state strategies, and federal exemptions. The report concludes with next steps, including a test case and ARL strategies.

Rémy, Elisabeth, Romain Escudier, and Alexandre Mignot. Access impact of observations. EuroSea, 2023. http://dx.doi.org/10.3289/eurosea_d4.8.

Full text

Abstract:

The accuracy of the Copernicus Marine Environment and Monitoring Service (CMEMS) ocean analysis and forecasts highly depend on the availability and quality of observations to be assimilated. In situ observations are complementary to satellite observations that are restricted to the ocean surface. Higher resolution model forecasts are required by users of the CMEMS global and regional ocean analysis and forecasts. To support this with an efficient observational constrain of the model forecast via data assimilation, an increase observation coverage is needed, associated with an improved usage of the available ocean observations. This work exploits the capabilities of operational systems to provide comprehensive information for the evolution of the GOOS. In this report, we analyse the use and the efficiency of the in-situ observations to constrain regional and global Mercator Ocean systems. Physical and biogeochemical variables are considered. The in-situ observations are used either to estimate physical ocean state at global and regional scale via data assimilation or to estimate BGC model parameters. The impact of the physical in situ observations assimilated in open ocean and coastal areas is assessed with numerical data assimilation experiments. The experiments are conducted with the regional 1/36° resolution and global 1/12° resolution systems operated by Mercator Ocean for the Copernicus Marine Service. For the global physical ocean, the focus is on the tropical ocean to better understand how the tropical mooring observations constrain the intraseasonal to daily variability and the complementarity with satellite observations and the deep ocean. The tropical moorings provide unique high frequency observations at different depth, but they are far away from each other, so part of the signal in the observation are decorrelated from one mooring to the others. It is only via an integrated approach, as data assimilation into a dynamical model and complementarity with other observing networks that those observations can efficiently constrain the different scales of variability of the tropical ocean circulation. As the satellite observations brings higher spatial resolution between the tropical moorings but for the ocean surface, we show that the tropical mooring and Argo profile data assimilation constrain the larger scale ocean thermohaline vertical structure (EuroSea D2.2; Gasparin et al., 2023). The representation of the high frequency signals observed at mooring location is also significantly improved in the model analysis compared to a non-assimilative simulation. The ocean below 2000 m depth is still largely under constrained as very few observations exist. Some deep ocean basins, as the Antarctic deep ocean, shows significant trend over the past decade but they are still not accurately monitored. Based on the spread of four deep ocean reanalysis estimates, large uncertainties were estimated in representing local heat and freshwater content in the deep ocean. Additionally, temperature and salinity field comparison with deep Argo observations demonstrates that reanalysis errors in the deep ocean are of the same size as or even stronger than the observed deep ocean signal. OSSE already suggested that the deployment of a global deep Argo array will significantly constrain the deep ocean in reanalysis to be closer to the observations (Gasparin et al., 2020). At regional and coastal scales, the physical ocean circulation is dominated by higher frequency, smaller scale processes than the open ocean which requires different observation strategy to be well monitor. The impact of assimilating high frequency and high-resolution observations provided by gliders on European shelves is analysed with the regional Iberic Biscay and Irish (IBI) system. It was found that repetitive glider sections can efficiently help to constrain the transport of water masses flowing across those sections. BGC ocean models are less mature than physical ocean models and some variable dependencies are still based on empirical functions. In this task, Argo BGC profile observations were used to optimize the parameters of the global CMEMS biogeochemical model, PISCES. A particle filter algorithm was chosen to optimize a 1D configuration of PISCES in the North Atlantic. The optimization of the PISCES 1D model significantly improves the model's ability to reproduce the North Atlantic bloom Recommendations on the in-situ network extensions for real time ocean monitoring are given based on those results, and the one also obtained in the WP2, Task 2.2 where data assimilation experiments but with simulated observations where conducted. Argo extension and the complementarity with satellite altimetry was also extensively studied. (EuroSea Deliverable ; D4.8)

Serafica, Ramonette, and Queen Cel Oren. Should the Philippines Adopt Net Neutrality Regulations? Philippine Institute for Development Studies, 2024. http://dx.doi.org/10.62986/pn2024.08.

Full text

Abstract:

Net neutrality is a contentious issue in internet regulation, looking at nondiscrimination and pricing policy. It espouses the idea that broadband service providers should charge consumers only once for internet access, not favor one content provider over another, and not charge content providers for sending information over broadband lines to end users. Advocates argue that this fosters innovation and protects freedom of expression, while critics warn that it could stifle investment and innovation. This paper examines the advantages and disadvantages of adopting net neutrality principles in the proposed Open Access in Data Transmission Act. While net neutrality can address legal obstacles, infrastructure gaps, and network discrimination, its unintended impacts on investment and innovation remain ambiguous. Thus, policymakers are advised to identify the public interest at stake, consider existing competition regulations and consumer protection laws, and assess possible impacts on the internet value chain. Also recommended is the elimination of barriers to entry and other restrictions within the internet access connectivity segment of the internet value chain.

Full text

Abstract:

The article analyzes the results of the survey of 75 lecturers on using learning content management system (LCMS) Moodle in the educational process. It is defined that more than 75% of the respondents use LCMS Moodle. The lecturers up to 30 or over 60 years old, with up to 3-year-work experience in Universities need methodic assistance. Textual e-learning resources are widely used in developed courses while video and audio are not used enough. LCMS Moodle is mostly used during exams or tests and student work, and using LCMS Moodle should be intensified in lectures, laboratory and practical classes. Among the most demanded resources are label, page, file, URL, book, assignment, attendance, glossary, quiz. Thus, the popularization of other resources is identified as one of the most important. An action plan how to improve LCMS Moodle usage: increasing the IT competencies of both teachers and students – planned long-term courses “IT in full-time (blended) learning”; seminars, consultations, (group and individual forms) both on general issues, and according to the specificity of the specialties; methodic handouts and recommendations; improving logistics; improving logistical support – ensuring constant access to the Internet, updating and equipping computer classrooms; creating of transparent, predictable and attractive for authors content of the regulatory framework.

Full text

Abstract:

The Zanzibar Ministry of Education and Vocational Training (MoEVT) and the World Bank (the Bank) approached the EdTech Hub (the Hub) in April 2020 to explore the feasibility of implementing a Virtual Learning Environment (VLE). The Hub was requested to focus primarily on the deployment of a VLE in lower secondary education, and this report consequently focuses primarily on this group. The report is structured in four sections: An introduction to provide the background and guiding principles for the engagement with a short overview of the methodology applied. An analysis of the Zanzibar education system with a particular focus on elements relevant to deploying a VLE. This includes the status of ICT infrastructure, and a summary of the stakeholders who will play a role in using or implementing a VLE. A third section that discusses types of VLEs and content organisation, and their applicability to the Zanzibar ecosystem. A conclusion with recommendations for Zanzibar, including short- and long-term steps. In this collaboration with Zanzibar’s MoEVT, the Hub team sought to understand the purpose of the proposed VLE. Based on discussions and user scenarios, we identified two main education challenges a VLE may help to resolve. In the short term, students cannot go to school during the COVID-19 crisis, but need access to educational content. There is content, but no flexible and versatile platform to disseminate content to all students. In the long term, a mechanism to provide students with access to quality, curriculum-aligned content in school, or remotely, is required.
