Intermediaries: bridges across the digital divide

2012

The challenge of bringing developing countries into the “information society” has been traditionally framed as bridging the digital divide. Meeting this challenge has predominantly been through technical solutions aimed at providing physical access to the Internet. Yet, other aspects of the divide such as low literacy rates, gender and religious issues arguably pose bigger hurdles in getting the benefits of the Internet to the vast majority of the population of developing countries. They are seldom aware of the information available on the net and even when they are, they have difficulty using it. To facilitate access and use of the Internet by the population, an intermediary is often neede…

Attribute based access control scheme with controlled access delegation for collaborative E-health environments

2017

Abstract Modern electronic healthcare (e-health) settings constitute collaborative environments with complex access requirements. Thus, there is a need for sophisticated fine-grained access control mechanisms to cater these access demands and thereby experience the full potential of e-health systems. In order to realize a flexible access control scheme, integrating access delegation is of paramount importance. However, access delegation has to be enforced in a controlled manner so that it will not jeopardize the security of the system. In this paper, we addressed this issue through proposing an attribute based access control scheme integrated with controlled access delegation capabilities. …

A cultural heritage experience for visually impaired people

2020

Abstract In recent years, we have assisted to an impressive advance of computer vision algorithms, based on image processing and artificial intelligence. Among the many applications of computer vision, in this paper we investigate on the potential impact for enhancing the cultural and physical accessibility of cultural heritage sites. By using a common smartphone as a mediation instrument with the environment, we demonstrate how convolutional networks can be trained for recognizing monuments in the surroundings of the users, thus enabling the possibility of accessing contents associated to the monument itself, or new forms of fruition for visually impaired people. Moreover, computer vision …
