ABSTRACT
In this era of cloud computing, protecting the data privacy is an important consideration. Also, due to the rapid growth of the
Internet and social networks, a user can easily gather large amount of data from different sources without worrying about its
copyright information. So it becomes essential for the data owner to add their ownership information into the data which can
be done by using watermark technique. Due to this, only authenticated users can reuse and republish the data. In this paper, we
propose an architecture that provides privacy protection of image data as well as the secure watermark extraction in a
simultaneous manner by using sparse sampling and secure computation. This paper enhances the privacy of data by applying
layer of encryption over the data using data hiding technique before it is passed to the sparse sampling transformation. This
will make the proposed architecture tolerable against the semi-honest security assumption required for the simultaneous
operation in sparse sampling domain. At the side of reconstructing an image, we proposed to yield with better quality and
robustness than the existing system.
