Robust and Blind Watermarking of Relational Database Systems
Problem statement: Digital multimedia watermarking technology was suggested in the last decade to embed copyright information in digital objects such images, audio and video. However, the increasing use of relational database systems in many real-life applications created an ever increasing need for watermarking database systems. As a result, watermarking relational database systems is now merg...
متن کاملA Blind Reversible Robust Watermarking Scheme for Relational Databases
Protecting the ownership and controlling the copies of digital data have become very important issues in Internet-based applications. Reversible watermark technology allows the distortion-free recovery of relational databases after the embedded watermark data are detected or verified. In this paper, we propose a new, blind, reversible, robust watermarking scheme that can be used to provide proo...
متن کاملRobust and Blind 3D Watermarking
3D watermarking is a technique to hide some information into the 3D graphical model in such a way that the watermarked object is visually indistinguishable from the original one. A robust and blind 3D watermarking method should be able to detect the embedded message after a certain level of malicious attack without having the original model. 3D watermarking has a great potential of usage in the...
متن کاملReversible Watermarking for Relational Database Authentication
A reversible watermarking scheme for relational databases is proposed in this paper to achieve lossless and exact authentication of relational databases via expansion on data error histogram. This reversible watermarking scheme possesses the ability of perfect restoration of the original attribute data from the untampered watermarked relational databases, thus guaranteeing a “clear and exact” t...
متن کاملRobust and Reversible Relational Database Watermarking Algorithm Based on Clustering and Polar Angle Expansion
Digital watermarking has been widely applied to relational database for ownership protection and information hiding. But robustness and reversibility are two key challenges due to the frequently database maintaining operators on those tuples. This paper proposes a novel relational database watermarking scheme based on a fast and stable clustering method on database tuples, which adopts Mahalano...
