CAREER: Systems for the emerging patterns of content exchange

我们正处于互联网内容创建和交换方式的根本性转变的开端。虽然内容以前主要是由一小部分组织创建的，但现在，个人用户--由于数字设备和社交网络的普及以及互联网接入的无处不在--正在创建内容，这些内容代表了互联网流量的很大一部分。不幸的是，现有技术和基础设施不适合新的内容创建和交换模式，导致基础设施和工作负载不匹配，这在从内容分发方式到用户能够表达访问控制的方式的地方都很明显。更糟糕的是，现有供应商开发新技术的速度一直很慢，因为他们目前的商业模式往往严重依赖现有方法。智力优势：在这些趋势的推动下，该项目正在开发适应不断变化的内容创建和交换模式的系统、网络和分发架构，使用户能够自由交换内容，并为最终用户生成的内容表达有意义的隐私政策。更广泛的影响：将应对这些挑战的责任完全下放给行业，有可能使当今的提供商处于确保内容只能以符合其商业利益的方式共享的地位。因此，拟议研究的影响可能会被在线社交网络的所有用户感受到，因此将产生重大的公众影响。

We are at the beginning of a fundamental shift in how content is created and exchanged over the Internet. While content was previously created primarily by a small minority of organizations, now, individual users--empowered by the popularity of digital devices and social networks, as well as the ubiquity of Internet access--are creating content that represents a significant fraction of Internet traffic. Unfortunately, existing techniques and infrastructure are ill-suited for the new patterns of content creation and exchange, resulting in a mismatch of infrastructure and workload that is evident in places ranging from the ways in which content is distributed to the ways in users are able to express access control. To make matters worse, existing providers have been slow to develop new techniques, as their current business models are often heavily reliant on existing approaches. Intellectual Merit: Motivated by these trends, this project is developing systems, networks, and distribution architectures that are tailored to the changing patterns of content creation and exchange, enabling users to freely exchange content and express meaningful privacy policies for end user-generated content. Broader Impact: Fully delegating the responsibility for addressing these challenges to industry risks entrenching the providers of today into a position of ensuring that content can only be shared in ways that are in-line with their business interests. Thus, the impact of the proposed research will be potentially felt by all users of online social networks, and will thus have significant public impact.
