Proximity Tracing Approaches - Comparative Impact Analysis
Although they address the same problem, the so-called “centralized” and “decentralized” approaches to COVID-19 proximity tracing rely on different threat model assumptions. The goal of this document is to analyze the impact of these two options in terms of privacy, security and reliability.The main objective of the decentralized approach is to protect users against a malicious server or a state-level adversary and to prevent the leak of sensitive data due to attacks or negligence at the server side. Therefore, the role of the server is reduced as much as possible, and the exposure verification is performed on the user device. In contrast, the centralized approach puts more emphasis on the protection of users against other malicious users trying to infer who is infected. Hence, the role of the server in the centralized approach is more important, including the verification of exposure.This design choice involves different privacy risks:● The decentralized approach provides many opportunities to malicious or curious users (through wide scale and undetectable attacks or during normal usage) to infer the identity of infected users or to monitor specific areas. These privacy risks coming from users (e.g., neighbors) can easily lead to abuses as well as stigmatization and harassment of diagnosed users. On the positive side, the server learns little information about users.● In the centralized approach, in contrast, the capability of users to learn who is infected is drastically limited. This better protection however comes at the cost of relying on a server which is able to learn some information about users.Law enforcement agencies and third parties colluding with the server are sources of risk in both approaches but they do not concern the same population. Only infected users who consent to declare themselves are concerned in the decentralized approach, while these risks concern all users (infected or not) in the centralized approach. However, the likelihood of these risks needs to be assessed and balanced, as all other risks, with the potential benefits of these applications in the fight against COVID-19. To this respect, the centralized approach can bring added value because the health authority is aware of the number of exposed people and can use it both for statistical purposes and to easily adjust the risk calculation algorithm (to decide if a user should be classified as “at risk”)
Connaissances des Znieff de Bourgogne :Côte beaujolaise et Massif du Beaujolais (71)
Dans le cadre de sa mission de connaissance des habitats naturels de la région, la délégation Bourgogne du CBNBP a réalisé en 2019 une étude des végétations des ZNIEFF des régions naturelles du Massif du Beaujolais (71) et de la Côte beaujolaise (71). En effet, les Znieff de type I sont des espaces homogènes écologiquement, définis par la présence d'espèces ou d'habitats rares, remarquables ou caractéristiques du patrimoine naturel régional.L’analyse des 103 relevés de végétation disponibles (60 relevés déjà dans la Base de Données Habitats et 43 nouveaux relevés réalisés entre mai et juillet 2019) a permis d’identifier 61 végétations (dont 24 sont à la fois d’intérêt européen et régional et 17 seulement déterminants Znieff). Cette liste de végétations permet de voir que la région naturelle est caractérisée par les milieux forestiers (22). Ils sont suivis par les zones humides (16) et les végétations prairiales et pelousaires (19), Tous ces milieux sont menacés, les végétations forestieres à cause de l’intensification sylvicole les végétations prairiales et pelousaires par la transformation en cultures et en peupleraies, en vallées, ; les végétations humides parce qu’elles sont atteintes par une eutrophisation générale. Dans le cadre de l’inventaire continu, les 9 Znieff de type I du Gâtinais seront parcourues en 2020 afin de compléter leur liste de végétations
A Taxonomy of Cyber-attacks on Computer Networks
Computer networks in the current state of the world have become an inevitability all around the world ever since it was put in motion. It has constantly gained users within businesses and organisations, and the users will tend to increase as more technology is invented. We need computer networks day-by-day, as it uses different computers within the same network to share files, resources and significant data. It is used within businesses and schools or could be part of the network which may be connected to the internet. When computer networks start growing as a whole, then the chances of cyber-attacks also starts to increase and the attack can happen when it is least expected. This is due to the fact that solutions aren't as effective as such. For example, resources, tools and framework cannot detect cyber-attacks that affect the organisation, before the attack is carried out [1]. Alongside this, when there is a large number of users on a specific network, then the network can become slow as it is sharing resources with more users, which could eventually lead it to shut down
A causally connected superluminal Natario warp drive spacetime ???
Warp Drives are solutions of the Einstein Field Equations that allows superluminal travel within the framework of General Relativity. There are at the present moment two known solutions: The Alcubierre warp drive discovered in 1994 and the Natario warp drive discovered in 2001. However one the major drawbacks concerning warp drives is the problem of the Horizons(causally disconnected portions of spacetime) in which an observer in the center of the bubble cannot signal nor control the front part of the bubble.The geometrical features of the Natario warp drive are the required ones to overcome this obstacle at least in theory. The behavior of a photon sent to the front of the warp bubble in the case of a Natario warp drive with variable velocity is the main purpose of this work.We present the behavior of a photon sent to the front of the bubble in the Natario warp drive in the 1+1 spacetime with both constant and variable velocities using quadratic forms and the null-like geodesics ds 2 = 0 of General Relativity and we provide here the step by step mathematical calculations in order to outline the final results found in our work which are the following ones: For the case of fixed velocities the Horizon exits in agreement with the current scientific literature but for the case of variable velocities the Horizon do not exists at all.Due to the extra terms in the Natario vector that affects the whole spacetime geometry this solution with variable velocities have different results when compared to the fixed velocity solution.Remember that we are presenting our results using step by step mathematics in order to better illustrate our point of view
