Security of Data stored in a database is an important measure of trust when database as a service paradigm is considered. In todays internet based applications and online storage systems the database service providers should implement proper privacy measures and take stringent actions against attacks and secure customers valuable data. In this paper, we anticipate the present day situations and attacks and suggest watermarking as a solution to achieve security against forgery and theft of databases. We give a brief account of audio, video, text and image water marking techniques. We identify important attacks in this sector and study their modus operandi. Our study also gives a survey about some of the past work and robust watermarking algorithms for relational databases and their advantages. Considering the present day importance of security we propose a two tier model for watermarking of databases. The two tier model watermarks a database as a whole along with the individual data objects stored in it.
