Efficient and secure sharing of scientific data remains a key challenge in the Open Science framework, especially in terms of data authenticity, provenance and privacy. Traditional digital repositories improve access but often lack decentralized mechanisms that guarantee integrity and traceability. Blockchain technology provides a potential solution through tamper-proof records and distributed consensus, while ...
Secure (HTTPS) in the entry pages of the official websites of all (308) Portuguese municipalities. This is relevant because such websites are typically used to provide transactional services to citizens, and citizens need to trust that websites are authentic and that confidentiality and integrity of the information exchanged is assured in the communication process. Automated and, whenever needed, manual analyse...
This paper presents a study on the evolution of the use of HTTPS by the official websites of all (308) Portuguese municipalities. One year ago, we found a bad situation regarding HTTPS usage: only a small percentage of websites adopted HTTPS correctly. The results were communicated to the relevant entities so actions could be taken. After one year, we performed a new assessment to check for evolution. This pape...
This paper presents a study on the adoption of HTTPS in the official websites of all (308) Portuguese municipalities. Automated and, whenever needed, manual analysis were used to investigate its entry pages. Specifically, the pages were checked for the existence of an HTTPS site; the correctness of the certificates and their certification chain; coherence between contents of the HTTP and HTTPS sites; redirectio...
In a world where people must subject themselves to high scrutiny in every process they initiate, and in a world where the digital environment grows incessantly, we anticipate more online services asking for personal attributes and their need to trust in such attributes. For tackling such need, we describe a proposal for a secure, decentralized and shared repository of certified personal attributes. Individuals ...
Between 2010 and 2015, the authors implemented a set of research-based learning activities in the context of two curricular units offered at the University of Aveiro in Portugal. Although initially designed with strictly pedagogical purposes and to familiarize students with research, these activities have formed the basis of several studies that have been published in journals and international conference proce...
A entrada da Guiné Equatorial na Comunidade dos Países de Língua Portuguesa (CPLP) tem sido muito contestada. Os críticos apontam motivações meramente económicas para a adesão de um país que, três anos depois, ainda não fala português mas continua rico em matérias-primas. Há também quem sinalize o incumprimento do roteiro para a adesão por parte do mais recente Estado-membro da comunidade lusófona no que diz re...
This paper assesses local e-government maturity in the Iberoamerican community. Sixty Andorran, Argentinian, Brazilian, Chilean, Colombian, Costa Rican, Mexican, Portuguese, Spanish, and Uruguayan cities were considered in this study. A demographic criterion was adopted to define the municipalities observed within those countries and a three-dimensional model was used to evaluate each municipal website. Then, w...
CHAPAS is a model for the provision of life event e-government services where no direct communication between service providers exists. The citizen, assisted by a personal tool (Chappie), is responsible to gather all the information required by the service he wants to apply to, possibly from services of other providers. In this paper we discuss how life event e-government services are provided in CHAPAS, from t...
