Many countries and international organizations, as well as individuals, are advocating or have already embodied it as a basic human right, thus enhancing the issues of whether it should be incorporated into the macro system of international human rights. By analyzing the facts, this article points out that the international concept of the right to internet access should be distinguished from its domestic concept, for there are no legal sources about the right to internet access for guidance as with some treaties in the current international law, despite its close relationship with some existing rights such as the freedom of speech, press and assembly, or the right of equality, or the right to development. And there is still a long time before the legal value and related responsibilities as well as the boundaries about the right to internet access becomes a consensus in the international society. Even though there is quite a possibility, this right hasn’t been embodied as part of international human rights, and thus hasn’t made a legal concept in international human right law.展开更多

While attempts to make Internet access a candidate for the standing of human right have become popular in both the political and legal arenas, we still lack serious philosophical reflection on this issue. The paper first evaluates the arguments made by various authors, and then moves to provide its own conclusions. Its logic is that if （i） Internet access is crucial for enabling democracy, and （ii） democracy is a basic human right, then we may have at least prima facie reason to see such a technology as a derived human right whose normativity supervenes on the right to democracy.展开更多

The protocol-based IAMC framework enables developers to create interoperable clients and servers easily and independently. Presented are conceptual and experimental work on the IAMC framework architecture and major components: the Mathematical Computation Protocol (MCP), a client prototype (Dragonfly), a server prototype (Starfish), a mathematical encoding converter (XMEC), and an open mathematical compute engine interface (OMEI).展开更多
