Valuing Differential Privacy : Assessing the value of personal data anonymization solutions, specifically Differential Privacy-solutions, for companies in the mobility sector / Värdering av Differential Privacy : En värdering av anonymiseringsalgoritmer, specifikt Differential Privacy-lösningar, för bolag inom mobilitetssektorn

Andersson, Axel, Borgernäs, Sebastian January 2022 (has links)
This paper aims to determine the value of the product based on the mathematical concept of Differential Privacy, by assessing the value of the business opportunities it enables and the value of the possible GDPR-fines it prevents. To delimit the scope of the research the analysis will focus on what the value of personal data is for companies within the mobility sector. Mobility is a cross-industrial sector consisting of companies within connectivity-technology, transportation, and automotive. The method used to assess the final value of anonymizing personal data, such as consumer data, using a DP-solution (meaning, an implementation of the theory) has consisted of both quantitative and qualitative analysis. The quantitative analysis aims to assess the ‘Cost of Risk’ for mobility companies that are exposed to personal integrity regulation due to data processing. To further conclude the true cost of the financial impact caused by getting fined for infringing on privacy regulation because of unlawful data processing is done through a complementary qualitative assessment. Lastly, the 'Opportunity Cost', or rather the cost of missed financial opportunities, is determined qualitatively for a case study company within Sweden’s mobility ecosystem to conclude the overall value of a DP-solution for a specific company. The final product of this research paper is to provide a framework assessing the total value, for specifically companies in the mobility sector, of implementing differential privacy solutions. / Syftet med denna uppsats är att fastställa värdet av anonymisering baserat på det matematiska konceptet Differential Privacy, genom att bedöma värdet av de affärsmöjligheter det skapar, samt värdet av de möjliga GDPR- böter det förhindrar. För att avgränsa studiens omfattning består analysen endast av att uppskatta dessa värden för företag inom mobilitetssektorn. Mobilitetssektorn är en tvärindustriell sektor som består av företag inom uppkoppling-, transport- och bilindustrin. Metoden som använts för att ta fram det slutliga värdet av att anonymisera persondata genom en differential privacy lösning, består både av en kvantitativ och en kvalitativ analys. Målet med den kvantitativa analysen är att estimera kostnadsrisken för företag inom mobilitetssektorn som exponeras mot GDPR-böter med avseende på dess datahantering. För att vidare ta reda på den totala finansiella inverkan av sådana böter, kompletteras analysen av en kvalitativ studie, som delvis omfattas av de finansiella möjligheterna ett företag går miste om i en sådan situation. Den kvalitativa analysen består också av en fallstudie av ett svenskt företag inom mobilitetssektorn, med målet att estimera värdet av de affärsmöjligheter som uppstår med hjälp av anonymisering av data. Slutligen är målet med denna uppsats att förse läsaren med att ramverk för att estimera det totala värdet av att implementera differential privacy lösningar i företag inom mobilitetssektorn.

L'accès des ménages abidjanais aux services de collecte des déchets : 3 essais d'évaluation des bénéfices. / The households access to waste collection services in Abidjan : three attempts of evaluation of profits

Koné, Noukignon 21 November 2017 (has links)
L’augmentation de la quantité des déchets ménagers dans le District d’Abidjan constitue une pression énorme pour l’environement et la santé des populations. Les soutiens ponctuels des organismes internationaux tels que la Banque Mondiale et la présence de nombreux acteurs (Etat, institutions internationales, acteurs locaux) n’ont pas empêché la persistance de la problématique de la gestion des déchets dans l’agglomération abidjanaise. La faiblesse du rendement et du taux de recouvrement de la Taxe d’Enlèvement des Ordures Ménagères imputée aux ménages pour la gestion des ordures, ne permet pas de répondre aux besoins de financement de la filière. Ainsi, cette thèse analyse les conditions et effets de l’accès des ménages d’Abidjan à un service amélioré de collecte des déchets. Pour cela, nous avons mené une enquête d’évaluation contingente (consentement à payer). En recourant à un modèle de choix discret (probit), nous avons pu mettre en évidence le lien entre les caractéristiques des ménages et leur volonté à participer à une gestion améliorée de leurs ordures. Nous avons démontré l’existence d’un lien entre l’accès à des services de collecte des déchets et aux latrines améliorées. Ce résultat va dans le sens des ODD qui préconisent une gestion intégrée de l’assainissement. Le recours à une méthode d’appariement a permis d’évaluer, de manière originale, les bénéfices du recours à un service informel de pré-collecte des déchets pour les ménages enquêtés. Les déterminants de la demande avérée pour un service informel ont d’abord été identifiés. L’indice de richesse (richesse matérielle), le genre, la durée de stockage des ordures, le fait que le ménage considère les maladies comme étant le problème majeur lié aux déchets, sont les facteurs qui expliquent le recours à un service de pré-collecte de leurs ordures. Par ailleurs, ce recours génère, d’après les résultats de la modélisation, des bénéfices socio-économiques quantifiables en termes d’une part, de développement socio-économique et humain et d’autre part, en termes de solutions de financement de la filière par la mise en place d’une taxe incitative (au ramassage des ordures). Enfin, à l’aide de la méthode des prix hédonistes appliquée aux données de notre enquête, nous avons identifié une relation positive entre les équipements de base d’un logement tel que l’accès à l’eau, à l’électricité et aux latrines et le prix des loyers. En revanche, la faible qualité du service actuel de collecte des ordures ménagères dans les quartiers enquêtés ou le fait que la charge liée à la collecte soit récurrente, expliqueraient sa non influence sur le prix locatif des logements. / The increase in amount of household wastes in Abidjan is an enormous strain on the environment and on the health of local populations.Support from international institutions such as the World Bank and the presence of many actors (State, international institutions and local actors) have not prevented the persistence of the waste management problem in Abidjan. In this thesis, we analyse the conditions and implications of households for improved waste collection service in Abidjan. For this, we conducted a contingent valuation survey (willingness to pay). By using a discrete choice (probit) model, we were able to highlight the link between household characteristics and their willingness to participate in improved waste management. We have demonstrated a link between access to waste collection services and improved latrines. This result is in line with the SDGs, which advocate integrated sanitation management.At first, the determinants of the demand turned out for an informal service were identified. The wealth index, the gender, the duration of storage of the garbage, the fact that the household considers the diseases as being the major problem bound to waste, are the factors which explain the recourse to a service of pre-collection of their garbage. Besides, this recourse generates, according to the results of the modelling, quantifiable socioeconomic profits in terms of socioeconomic and human development in the first hand and on the other hand, in terms of solutions of financing of the sector by the implementation of an incentive tax. Finally, by using the hedonic price method, which applied to our survey data, we identified a positive relationship between the basic attachments of a dwelling such as access to water, electricity and latrines and the price of rents. On the other hand, the low quality of the current garbage collection service would explain its no-influence on the rental price of housing

Odhalené preference pro rekreaci v přírodě - česká a evropská perspektiva / Revealed preferences for outdoor recreation in natural areas - Czech and European perspective

Kaprová, Kateřina January 2019 (has links)
K. Kaprová (2019): Revealed preferences for outdoor recreation in natural areas - Czech and European perspective Abstract of the Doctoral Dissertation The dissertation thesis focuses on the investigation and synthesis of recreation welfare benefits associated with natural areas in the Czech Republic and in Europe. The dissertation thesis consists of five case studies. These represent various geographic levels of analysis: the level of one single recreation locality, the national level that takes into account large natural recreation sites in the Czech Republic (including protected areas), and a synthesis of results of studies on the European level. The methodological approach is based on the theory of environmental economics and employs non-market valuation techniques based on methods of revealed preferences, namely the hedonic pricing method and two types of travel cost modelling. In Study I, we examine how the presence and characteristics of urban greenery affect property prices in Prague. The results confirm that proximity to greenery and its area are important determinants of housing prices in Prague, which means that residents realize the positive values provided by urban greenery, including recreational ecosystem service. Benefits to residents differ with the type of greenery. Urban forests have the...
