SoNeUCONABC , an expressive usage control model for Web-Based Social Networks

by Lorena González-manzano, Ana I. González-tablas, José M. De Fuentes, Arturo Ribagorda - Computers & Security, In Press , 2014
"... In the era of hyper-connectivity Web-Based Social Networks (WBSNs) are de-manding applications. They facilitate the interaction of huge amounts of users and the development of appropriate Access Control Models (ACMs) is an aris-ing necessity. Particularly, the development of WBSNs ACMs with expressi ..."

with expressive power and capable of managing access control along the whole usage process is the challenge pursued. To contribute on this issue, first, 23 proposals have been analysed and second, SoNeUCONABC, an expressive usage control model for WBSNs, is proposed. It extends UCONABC [1] including relationships

SoNeUCONADM: the administrative model for SoNeUCONABC usage control model

by Ana I. González-tablas, Jose ́ M. De Fuentes, Arturo Ribagorda
"... Abstract—The popularity of Web Based Social Networks (WBSNs) encourages their enhancement. Many WBSN data is considered personal data and access control management plays a key role in this regard. The point is not only to manage access control but to determine how administration should be performed. ..."

"... ABSTRACT This article aims at proposing some elements for a grounded theor y of the network society. The network society is the social structure characteristic of the Information Age, as tentatively identi ed by empirical, cross-cultural investigation. It permeates most societies in the world, in v ..."

Once we control for network effects in our models of fund and portfolio company performance, the importance of how much investment experience a VC has is reduced, and in some specifications, eliminated. Finally, we provide initial evidence on the evolution of VC networks. Key words: Venture

In particular, we show how users within very different schemes of data-distribution (centralized, dht, unstructured P2P,etc) can still transparently
