The vast usage of digital multimedia content in public communication system has raised an increasinglyimportant issue for content owners and service providers. Digital watermarking provides techniques to hide watermarks intodigital content to achieve copyright protection and prevent its illegal copy or reproduction.This paper proposes a novelmethod for watermarking relational databases based on hybrid model optimization in which the embedding and extractingalgorithms of watermarking in discrete wavelet transform (DWT) are combined with Genetic Algorithm(GA) -BacterialForaging Algorithm(BFO) based optimization techniques for watermarking . We use the 5-level DWT for the spatialtransform; because of this we get the more accurate watermark. Identification of owner is cryptographically made secureand used as an embedded watermark. Strength of BFA is explored to make the technique robust, secure an d imperceptible.
