Many grid usage scenarios depend on small, dynamic working groups for which the ability to establish transient collaboration with little or no intervention from resource administrators is a key requirement. The system developed, PRIMA, focuses on the issues of management and enforcement of fine-grained privileges. Dynamic account creation and leasing as well as expressive enforcement mechanisms...

Numerous countries around the world have enacted privacy-protection legislation, in an effort to protect their citizens and instill confidence in the valuable business-to-consumer E-commerce industry. These laws will be most effective if and when they establish a standard of practice that consumers can use as a guideline for the future behavior of e-commerce vendors. However, while privacy-prot...

The spectrum access rights granted by the Federal government to spectrum users come with the expectation of protection from harmful interference. As a consequence of the growth of wireless demand and services of all types, technical progress enabling smart agile radio networks, and on-going spectrum management reform, there is both a need and opportunity to use and share spectrum more intensive...

Computational grids and other heterogeneous, large-scale distributed systems require more powerful and more flexible authorization mechanisms to realize fine-grained access-control of resources. Computational grids are increasingly used for collaborative problem-solving and advanced science and engineering applications. Usage scenarios for advanced grids require support for small, dynamic worki...

In this paper we analyze the requirements access control mechanisms must fulfill in the context of group communication and define a framework for supporting fine-grained access control in client-server group communication systems. Our framework combines rolebased access control mechanisms with environment parameters (time, IP address, etc.) to provide support for a wide range of applications wi...

The global area under genetically modified (GM) crops grew rapidly in the first ten years of GM technology adoption. However, the protection of innovators’ intellectual property rights (IPRs) has remained controversial, especially in developing countries, where IPR enforcement is lax. Weak enforcement of IPRs in developing countries has resulted in the failure of markets to transfer rents from ...

Although the ILO has been in existence for over a century, it is not equipped with international mechanisms enforcement of labour standards that promotes. Globalization and trade liberalization have exposed strong relationship between rights regulation, leading to attempts regulate provisions context, initially through WTO and, more recently, clauses bilateral regional free agreements (FTAs). T...

according to the articles 169 to 179 of the civil judgment enforcement law, the enforcement of the foreign judgment in the iranian law is based on the reciprocal act. but extension of international relations in the world today, above all in the commercial domain, requires that enforcement of foreign judgment be accepted after obtaining its correctness conditions based on res judicata. therefore...
