This open access book describes the technologies needed to construct a secure big data infrastructure that connects data owners, analytical institutions, and user institutions in a circle of trust. It begins by discussing the most relevant technical issues involved in creating safe and privacy-preserving big data distribution platforms, and especially focuses on cryptographic primitives and privacy-preserving techniques, which are essential prerequisites. The book also covers elliptic curve cryptosystems, which offer compact public key cryptosystems; and LWE-based cryptosystems, which are a type of post-quantum cryptosystem. Since big data distribution platforms require appropriate data handling, the book also describes a privacy-preserving data integration protocol and privacy-preserving classification protocol for secure computation. Furthermore, it introduces an anonymization technique and privacy risk evaluation technique. This book also describes the latest related findings in both the living safety and medical fields. In the living safety field, to prevent injuries occurring in everyday life, it is necessary to analyze injury data, find problems, and implement suitable measures. But most cases don’t include enough information for injury prevention because the necessary data is spread across multiple organizations, and data integration is difficult from a security standpoint. This book introduces a system for solving this problem by applying a method for integrating distributed data securely and introduces applications concerning childhood injury at home and school injury. In the medical field, privacy protection and patient consent management are crucial for all research. The book describes a medical test bed for the secure collection and analysis of electronic medical records distributed among various medical institutions. The system promotes big-data analysis of medical data with a cloud infrastructure and includes various security measures developed in our project to avoid privacy violations.

À l'ère d'Internet, l'expression de nos identités numériques est prise en porte-à-faux. D'un côté, l'invention par les citoyens-internautes de nouvelles modalités d'expression et de revendications identitaires, individuelles et collectives sont susceptibles de renforcer le lien social et l'existence démocratique. D'un autre côté, la propension de contrôle de ces identités à des fins économiques et politiques s'accroît via la captation, la fidélisation et la traçabilité des profils. Répression et surveillance de nos comportements numériques semblent plus que jamais d'actualité. Comment maîtriser ses identités numériques ? Peut-on être personne sur le réseau ? Peut-on effacer ses traces ? Que faire de tous nos mots de passe et identifiants ? Ce volume des Essentiels d'Hermès propose de mettre en lumière les ressorts et dilemmes de la présence en ligne et de l'« être ensemble », ou autrement dit de la communication à l'ère numérique.

Understanding an organization?s reliance on information systems and how to mitigate the vulnerabilities of these systems can be an intimidating challenge--especially when considering less well-known weaknesses or even unknown vulnerabilities that have not yet been exploited. The authors introduce the Vulnerability Assessment and Mitigation methodology, a six-step process that uses a top-down approach to protect against future threats and system failures while mitigating current and past threats and weaknesses.

Qu’est-ce que l’identité numérique et l’e-réputation ? Cette question se pose aujourd’hui dans le cadre de l'écosystème internet pour les usages individuels et collectifs. Cet ouvrage présente de manière accessible l'état de la recherche sur ces questions et propose un tour d'horizon des enjeux fondamentaux à maîtriser pour pouvoir garder le contrôle sur sa présence en ligne ou sur celle de son organisation. Ce livre s'adresse à ceux qui, soucieux de découvrir la richesse de cette problématique, aux entreprises, organisations et collectivités à la recherche d'une méthodologie et de bonnes pratiques sur ces questions, ainsi qu'à toute personne qui s'est déjà, ne serait-ce qu'une fois, posé la question de savoir si la publication d'une information, d'une vidéo, d'une photographie, d'un statut Facebook, ne risquait pas de lui porter un jour préjudice, à lui, à l'un de ses proches ou à son employeur. Et surtout, ce livre s'adresse à toutes les personnes qui ne se sont jamais posées cette question. Cet ouvrage a été réalisé avec le soutien du Labex Hastec.

For cloud users and providers alike, security is an everyday concern, yet there are very few books covering cloud security as a main subject. This book will help address this information gap from an Information Technology solution and usage-centric view of cloud infrastructure security. The book highlights the fundamental technology components necessary to build and enable trusted clouds. Here also is an explanation of the security and compliance challenges organizations face as they migrate mission-critical applications to the cloud, and how trusted clouds, that have their integrity rooted in hardware, can address these challenges. This book provides: Use cases and solution reference architectures to enable infrastructure integrity and the creation of trusted pools leveraging Intel Trusted Execution Technology (TXT). Trusted geo-location management in the cloud, enabling workload and data location compliance and boundary control usages in the cloud. OpenStack-based reference architecture of tenant-controlled virtual machine and workload protection in the cloud. A reference design to enable secure hybrid clouds for a cloud bursting use case, providing infrastructure visibility and control to organizations. "A valuable guide to the next generation of cloud security and hardware based root of trust. More than an explanation of the what and how, is the explanation of why. And why you can’t afford to ignore it!" —Vince Lubsey, Vice President, Product Development, Virtustream Inc. " Raghu provides a valuable reference for the new 'inside out' approach, where trust in hardware, software, and privileged users is never assumed—but instead measured, attested, and limited according to least privilege principles." —John Skinner, Vice President, HyTrust Inc. "Traditional parameter based defenses are in sufficient in the cloud. Raghu's book addresses this problem head-on by highlighting unique usage models to enable trusted infrastructure in this open environment. A must read if you are exposed in cloud." —Nikhil Sharma, Sr. Director of Cloud Solutions, Office of CTO, EMC Corporation.
