Abstract(s)
A Identidade Auto-Soberana é um novo modelo de identidade digital na internet, ou seja,
uma nova forma de provarmos quem somos para os sites, serviços e aplicações com as quais
precisamos estabelecer relacionamentos confiáveis para aceder ou proteger informações privadas.
É o conceito de que indivíduos e empresas podem armazenar os seus próprios dados de identidade
nos seus próprios dispositivos; escolher quais as informações a compartilhar com os validadores,
sem depender de um repositório central de dados de identidade.
Este estudo analisa qual poderá ser, por parte da população portuguesa, a aceitação da
tecnologia de Identidade Auto-Soberana, analisando o ‘Nível de Conhecimento’ à data da
realização do estudo. Recorre-se a uma versão adaptada do Technology Acceptance Model (TAM),
proposto por Davis (1989), que procura analisar as relações entre o conjunto de variáveis ‘Utilidade
Percebida’, ‘Facilidade de Utilização Percebida’ e ‘Risco Percebido’, para perceber qual a intenção
comportamental de uso desta tecnologia, por outras palavras, poder-se-á afirmar que uma
tecnologia é aceite, caso esta seja vista como segura, necessária e útil. A recolha da amostra é feita
através de um questionário publicado.
Os resultados obtidos mostram que uma esmagadora maioria da população da amostra não
conhece a tecnologia da Identidade Auto-Soberana. O ‘Nível de Conhecimento’ não apresenta
correlação com as restantes variáveis, ou seja, demonstra não ter influência. A análise do ‘Risco
Percebido’, conclui que existe receio na intenção de utilização desta tecnologia, dado ao ‘Risco
Percebido’. Não obstante, relativamente às conclusões observadas, existe uma limitação sobre a
população da amostra do estudo, a qual não reflete todos os segmentos da sociedade, recomendando
que numa análise futura, se consiga uma amostra mais diversificada. Como recomendação destaca-
se a necessidade de aumentar o conhecimento das pessoas sobre a Identidade Auto-Soberana, e
reduzir o risco percebido entre os utilizadores.
A Self-Sovereign Identity (SSI) is a new digital identity model used on the internet, it is an alternative way to validate who we are on websites, services and applications in which we need to establish trusting relationships to access or protect private information. It’s main purpose is so that individuals and companies can store their own identity data on their own devices; choose what information to share with validators, without relying on a central repository of identity data. This study analyzes what would be the Portuguese population's level of acceptance towards technology such as the Self-Sovereign Identity, analyzing the ‘Level of Knowledge’ at the time of the study. An adapted version of the Technology Acceptance Model (TAM) proposed by Davis (1989) is used, which seeks to analyze the relationships between a set of variables 'Perceived Usefulness', 'Perceived Ease of Use' and 'Perceived Risk', to understand the intended use of the technology under study, in other words, it may be perceived that a technology is only accepted if it is considered as safe, necessary, and useful. The data collection of the sample is done through a published questionnaire. The results obtained shows that the majority of the sample population does not familiar with the Self-Sovereign Identity technology. The 'Level of Knowledge' does not correlate with the other variables, that is, it demonstrates that it has no influence. The analysis of the 'Perceived Risk' concludes that there is fear in the intention of using this technology, given the 'Perceived Risk'. However, regarding the observed conclusions, there is a limitation on the population of the study sample, which does not reflect all segments of society, recommending that in a future analysis, a more diversified sample be obtained. As a recommendation, we highlight the need to increase people's knowledge about the SSI and reduce the perceived risk among users.
