In a broader sense, the human-centered equivalents of experience and trust apply to D2D interaction. Ubiquitous computing (UbiComp) embeds intelligence and computing capabilities in everyday objects to make them effectively communicate, share resources, and perform useful tasks. The safety of resources is a serious problem. As a result, authorization and access control in UbiComp is a significant challenge. Our work presents experience as an outcome of history (HI), reliability (RL), transitivity (TR), and Ubiquity (UB). This experience model is easily adaptable to a variety of self-regulating context-aware access control systems. This paper proposes a framework for Experience-Based Access Control (EX-BAC) with all major services provided by the model. EX-BAC extends attribute-based access control. It uses logical device type and experience as context parameters for policy design. When compared with the state-of-the-art, EX-BAC is efficient with respect to response time.展开更多

This serves as a unique and valuable means of the public communication of science and technology and informal science education activities, with the public at the centre of the process. To achieve this, SRWs integrate action and reflection not as a dichotomy, but as a complementary relation in which sensorial interaction is not a thoughtless process and mental activity is not disembodied. In this way, SRWs create virtuous cycles of meaningful learning.However, SRW practitioners thus far have not paid enough attention to the development of a theoretical foundation to support their strategies;they remain highly dependent on empirical experience and tacit knowledge. The little attention paid to the creation of a conceptual framework represents a critical barrier for reflection, discussion and, with them, the maturation of the SRW community.This work links a characterization of the SRW, built upon empirical experiences, to a variety of learning theories to identify an essential basis for discussion on the subject. Our objective is to complement the rich empirical tradition of the SRW with analytic elements intended to encourage discussion and promote—as tends to happen in activities with the public—virtuous cycles of theory and practice.展开更多
