Vidhi Khanduja, Shampa Chakraverty, Om Prakash Verma · Gate to Computer Science and Research · 2016
Databases play a pivotal role in all domains of technology, encompassing data mining, medical records, stock market data, e-commerce etc.With this elevated need for databases and their wide distribution in the web sphere, their security has become a major concern today.It is in this context that watermarked protection of databases has started receiving increasing attention from researchers.We present two of the most important security concerns related to protection of relational database: (i) Ownership proof and (ii) Tamper detection.We explain the functions of various components of a Robust Watermarking Model (RWM) to resolve ownership issues and a Fragile Watermarking Model (FWM) to deal with Integrity issues.We discuss various attacks that are possible on databases and present the appropriate security solutions to overcome them.
