The proposed system Privacy-Preserving Digital Rights
Management (DRM) in Cloud Networking is the concept for
computer networking and management for software product
purchasing on internet or cloud along with rights assign to the
authorized users within the Cloud along with security which
can be achieved by preserving the privacy of the software
products in a friendly manner. At the same time, this approach
guarantees that software is bound to users and their validity is
checked before execution. This is done using RSS feed of

details of students of that particular branch. This feed is
designed using MYSQL and XML.
1.2 Digital Rights Management (DRM):
DRM is the tool used to secure the digital
contented on internet. So RSS feed is protected using DRM
techniques on cloud. When the product of RSS feed is
