This paper proposes a zero-watermark scheme with geometrical invariants using support
vector machine (SVM) classifier against geometrical attacks for image authentication. Here …

Digital watermarking is considered one of the most promising techniques to verify the
authenticity and integrity of digital data. It is used for a wide range of applications, eg …

We put forward a fragile zero watermarking scheme to detect and characterize malicious
modifications made to a database relation. Most of the existing watermarking schemes for …

Over the past few years, reversible watermarking techniques for relational databases have
been proposed to provide protection of ownership rights, data tempering, and data integrity …

In 2002, Agrawal and Kiernan defined six basic requirements, including preventing illegal
watermark embedding and authentication, reversibility, robustness, and others, which must …

In this paper, we propose an efficient distortion-free watermarking of large-scale data sets in
various formats by exploiting the power of parallel and distributed computing environment. In …

In this paper, we present our design of a new, blind, reversible, robust, watermarking
scheme for relational databases storing textual and numerical data, which is not only …

The protection of database systems content using digital watermarking is nowadays an
emerging research direction in information security. In the literature, many solutions have …

In the era of big data, secure and controlled data publishing becomes increasingly vital.
When data holders publish dataset to data demanders, data holders often (1) protect the …

In the era of big-data when volume is increasing at an unprecedented rate, structured data is
not an exception from this. A survey in 2013 by TDWI says that, for a quarter of …
