A Reversible Watermarking Technique for Ownership Protection and Data Recovery

Computer Engineering

Watermarking is commonly used technique in which, information is enforced to prove ownership on different types of data such as image, audio, video, text and relational database. There are many watermarking techniques for databases. Social network data are being mined for extracting knowledge and patterns. Such data are composed by different researchers and organizations and this are usually also shared via different channels. These data is usually big in volume because there are millions of social network users all over the world. Ownership protection of such data with huge volume becomes relevant. Digital watermarking is a more demanding solution than any other technique for ensuring rights protection and integrity of the original data sets. The leading objective is to devise a reversible watermarking technique for the social network data to prove ownership rights and also provide a mechanism for data recovery. Robustness of the proposed technique is evaluated through attack analysis using experimental study
