ABSTRACT:
With
the development of Internet technology and human computing, the computing
environment has changed dramatically over the last three decades. Cloud
computing emerges as a paradigm of Internet computing in which dynamical,
scalable and often virtualized resources are provided as services. With
virtualization technology, cloud computing covers diverse services (such as
virtual computing, virtual storage, virtual bandwidth, etc.) for the public by
means of multi-tenancy mode. Although users are enjoying the capabilities of
super-computing and mass storage supplied by cloud computing, cloud security
still remains as a hot spot problem, which is in essence the trust management
between data owners and storage service providers. In this paper, we propose a
data coloring method based on cloud watermarking to recognize and ensure mutual
reputations. The experimental results show that the robustness of reverse cloud
generator can guarantee users0 embedded social reputation identifications.
Hence, our work provides a reference solution to the critical problem of cloud
security.
