Convenient Move of Digital Content Using RFID in Home Networks

A home network consists of home appliances, and they are being expanded with home appliance development. The amount of digital content in home networks is therefore increasing tremendously. But continuous protection of digital content authentication is difficult, because of a lack of digital content management between devices. Devices should reissue licenses from DRM servers, and then content will be able to shift toward each device. In this paper, a framework which freely moves digital content by device authentication to other devices in a home network is proposed. In addition, a system which reduces a DRM server"s work with license issues and management, and the even outside approaches, will be able to control the system by device authentication from a home network sever.
