In any economic paradigm, the concept of ownership is fundamental. From the concrete ownership of goods and services, one has the more abstract ownership of buying potential in the form of currency. We are witnessing a digital revolution in which our world is being recast in an information-based paradigm, and currency is no exception. Bitcoin is a digital currency that uses a set of protocols (based on blockchains) that are intended to eliminate the need of intermediaries to conduct transactions. A transaction may be seen as an access control and thus, while bitcoins are seen at first as currency, the underlying blockchain infrastructure can be used for other applications involving access control, such as Digital Rights Management. In this project, we will look at an innovative but practical blockchain based solution to DRM.

在任何经济模式中，所有权的概念都是基本的。从商品的具体所有权 和服务，人们拥有以货币形式购买潜力的更抽象的所有权。我们 目睹了一场数字革命，我们的世界正在以信息为基础的范式重新塑造， 货币也不例外。比特币是一种数字货币，它使用一套协议（基于区块链）， 旨在消除中介人进行交易的需要。交易可以被视为 访问控制，因此，虽然比特币最初被视为货币，但底层区块链基础设施可以 可用于涉及访问控制的其他应用程序，例如数字版权管理。本课题 将着眼于一个创新但实用的基于区块链的DRM解决方案。
