TLDR
A novel watermarking method is proposed, which embeds an image watermark into relational database, and experimental results verify the effectiveness of the proposed method.Abstract:
As an embranchment of information hiding, the digital watermark techniques have been attracting more and more interests in both research and industrial fields. As a tool for storing and managing data, relational database is widely used in many information systems. It is a crucial issue to protect the copyright of relational data. In order to make watermarking information more intuitive and easier to identify, We propose a novel watermarking method, which embeds an image watermark into relational database. Experimental results verify the effectiveness of the proposed method.read more

Robust and Blind Watermarking of Relational Database Systems
Ali Al-Haj,Ashraf Odeh +1 more
TL;DR: This study proposed an efficient database watermarking algorithm based on inserting binary image watermarks in non-numeric mutli-word attributes of selected database tuples that is robust as it resists attempts to remove or degrade the embedded watermark and blind as it does not require the original database in order to extract the embeddedWatermark.
Reversible Watermarking for Relational Database Authentication
Yong Zhang,Bian Yang,Xiamu Niu +2 more
TL;DR: This reversi-ble watermarking scheme possesses the ability of perfect restoration of the original attribute data from the un-tampered watermarked relational databases, thus guaranteeing a “clear and exact” tampered-or-not authenti-cation without worry about causing any permanent distortion to the database.

TL;DR: A data coloring method based on cloud watermarking to recognize and ensure mutual reputations and the experimental results show that the robustness of reverse cloud generator can guarantee users’ embedded social reputation identifications.

A new watermarking approach for relational data
TL;DR: This paper presents an effective watermarking technique for relational data that is robust against various attacks, and inserts new tuples that are not real and called "fake" tuples, to the relation as watermarks.

A Speech Based Algorithm for Watermarking Relational Databases
TL;DR: Speech signal is introduced as watermark to be embedded into the relations and associated novel watermark insertion algorithm and detection algorithm are proposed for copyright protection.

Resolving rightful ownerships with invisible watermarking techniques: limitations, attacks, and implications
TL;DR: It is shown that, in certain applications, rightful ownership cannot be resolved by current watermarking schemes alone, and existing techniques are attacked by providing counterfeit water marking schemes that can be performed on a watermarked image to allow multiple claims of rightful ownership.

Watermarking digital images for copyright protection
TL;DR: The authors demonstrate a solution to one of the key problems in image watermarking, namely how to hide robust invisible labels inside grey scale or colour digital images.
