Kunskap om lösenord och deras säkerhet är idag något som förbises av den gemene datoranvändaren. Lösenordshanterare kan både hjälpa och skydda vid hanteringen av lösenord. De flesta webbläsare idag har inbyggda funktioner för lösenordshantering. Utifrån existerande litteratur kunde det identifieras att det behövs data kring vilka faktorer som påverkar webbläsares användare att använda respektive inte använda dessa inbyggda lösenordshanterare. Syftet med rapporten är att presentera en analys av faktorer som påverkar varför privatpersoner väljer att använda respektive inte använda webbläsares inbyggda lösenordshanterare. Resultatet presenteras med hjälp av kvalitativa semi-strukturerade intervjuer där 33 respondenter deltagit och besvarat frågor kring deras hantering av lösenord och användning av webbläsares inbyggda lösenordshanterare. Resultat från intervjuer visade att faktorer som var av betydande roll för ickeanvändande respondenter var starkt kopplade till datorvana och hur ofta respondenter använde datorn. De faktorer som spelade störst roll för användare av verktyget var enkelhet och tidseffektivitet. Icke-användare tenderade att ha en behovsbrist gällande verktyget, mestadels på grund av deras avsaknad av datoranvändning. Faktorer som påverkar användare och icke-användare visade sig stämma överens med tidigare forskning. Dessutom sammanfattades att antalet respondenter som var användare av lösenordshanterare var betydligt högre än vad som tidigare hävdats i litteratur. Majoriteten av respondenterna (79%) var användare av lösenordshanterare, vilket motsäger tidigare studier som utförts där endast 23% använder sig av lösenordshanterare. / Knowledge of passwords and their security is today something that is overlooked by the everyday computer user. Password managers can both help and protect when managing passwords. Most web browsers today have built-in password management features. Based on existing literature, it could be identified that there is a need for knowledge concerning which factors influence web browser users to use or not use their built-in password managers. The purpose of the report is to present an analysis of factors that affect why private individuals choose to use or not use browsers built-in password managers. The results are presented with the help of qualitative semi-structured interviews in which 33 respondents participated and answered questions about their handling of passwords and the use of web browsers built-in password managers. Results from the interviews showed that factors that were significant for non-user respondents were strongly linked to computer skills and how often respondents used the computer. The factors that played the biggest role for users of the tool were simplicity and time efficiency. Non-users tended to have a lack of need for the tool, mostly because of their lack of computer usage. Factors affecting users and non-users were found to be consistent with previous research. In addition, it was concluded that the number of respondents who were users of password managers was significantly higher than previously claimed in the literature. The majority of respondents (79%) were users of password managers, which contradicts previous studies conducted where only 23% use password managers.

Les mégadonnées font partie de ces sujets dont on entend parler sans trop savoir ce qu’ils signifient précisément. Souvent associés au domaine de l’intelligence artificielle, ces volumineux ensembles de données sont à la base d’un nombre croissant de modèles d’affaires axés sur la valorisation des données numériques que nous générons au quotidien. Le présent mémoire cherche à démontrer que cette exploitation des mégadonnées par les entreprises ne s’effectue pas dans un vide juridique. Les mégadonnées ne peuvent être considérées comme un objet de droit en l’absence d’une définition formelle. Une revue de la littérature multidisciplinaire à leur sujet, invite à les concevoir comme un actif informationnel doté de cinq caractéristiques principales, soit leur volume, leur vélocité, leur variété, leur valeur et leur véracité. L’analyse de ces caractéristiques permet au juriste d’atteindre une compréhension suffisante de ce phénomène afin de l’aborder sous le prisme du droit positif. Suivant un exercice de qualification juridique, les mégadonnées émergent à la fois comme un bien meuble incorporel et comme un ensemble de documents technologiques portant divers renseignements dont certains peuvent être qualifiés de renseignements personnels. Le cadre juridique applicable à l’exploitation des mégadonnées s’articule donc autour de la protection législative de la vie privée informationnelle qui s’incarne à travers les lois en matière de protection des renseignements personnels. Cet encadrement est complété par certaines règles relatives à la gestion documentaire et au droit à l’égalité. Une manière efficace de présenter cet encadrement juridique est selon le cycle de vie des renseignements personnels au sein des mégadonnées. Ainsi, il appert que les principes issus de l’approche personnaliste et minimaliste du droit québécois à la protection des renseignements personnels s’appliquent tant bien que mal à la collecte des données numériques ainsi qu’à leur traitement par les entreprises. / Big data is one of those topics we keep hearing about without knowing exactly what it means. Often associated with the field of artificial intelligence, these large datasets are the backbone of a growing number of business models that focus on leveraging the digital data we generate on a daily basis. This Master’s thesis seeks to demonstrate that this exploitation of big data by businesses is not happening in a legal vacuum. Big data cannot be considered as an object of rights in the absence of a formal definition. A review of the multidisciplinary literature on the subject invites us to conceive them as an information asset with five main characteristics: volume, velocity, variety, value and veracity. The study of these characteristics allows the jurist to reach a sufficient understanding of the phenomenon in order to approach it through the lens of positive law. Following a legal qualification exercise, big data emerges both as intangible movable property and as a set of technological documents carrying various types of information, some of which can be qualified as personal information. The legal framework governing the exploitation of big data is therefore built around the legislative protection of informational privacy, which is embodied in privacy laws. This framework is complemented by certain rules relating to document management and the right to equality. An effective way to present this legal framework is according to the life cycle of personal information within big data. Thus, it appears that the principles stemming from the personalist and minimalist approach of Quebec's data protection law apply, albeit not without struggle, to the collection of digital data as well as their processing by businesses.
