Content Espresso: A Global Secure Large File Sharing System for Media Industries

Abstract

Recently, it becomes common to handle large files in computers. However, we have a difficulty to realize file sharing over networks, especially for large files. The problem is that we have extended the system model designed decades ago based on a stand-alone computer model. Assuming that all files are located in data centers, and nobody accesses them at the sites, we can redesign the file sharing system model for higher access speed and efficient storage resource usage. We designed a global secure file sharing system called Content Espresso. In this paper, we describe the difficulty, the design goal for global secure file sharing system, and our approach for it. Finally, we explain the impact of Content Espresso on network.
